Where others have become obsessed with speed and trends, Sergio Membrillas has built a career on slowing down and staying true to his craft. Over 13 years as a professional illustrator, he's evolved a distinct style – bold, graphic, and quietly playful – that feels both timeless and entirely his own. But this evolution, as he's quick to point out, wasn't something he forced. "I believe evolution is essential for every artist," Sergio reflects. "Change is not something I resist; it's something I enjoy and welcome as part of the creative journey." His work, initially influenced by a love of Mid-Century graphic design, has gradually absorbed references as diverse as Etruscan art, Mesopotamian motifs, and early 20th-century traditional tattoos. It's a portfolio built on curiosity, not conformity. Despite his stylistic clarity, Sergio's process remains refreshingly analogue at its core. He still begins each project with pencil and paper, leaning into the tactility of drawing by hand. "I've always valued having a physical relationship with art," he says. "There's something essential about feeling the wood of the pencil, manually erasing mistakes, rather than simply double-tapping a screen." His philosophy of working slowly, attentively, and with purpose shows in the balanced compositions and confident use of negative space that has become his signature. Sergio credits his background in graphic design for this instinctive sense of structure. "There has always been a strong graphic sensibility within me," he says, noting that the discipline of design continues to inform his illustration practice, particularly in editorial and poster work where clarity and storytelling must co-exist. Yet, like many creative careers, his path into illustration wasn't plotted from the start. Initially, Sergio imagined illustration would complement his design projects, not become the main event. "At first, I thought I would incorporate my illustrations into my graphic design projects – but in the end, it turned out to be the other way around." A commission for EasyJet's in-flight magazine marked a pivotal moment that reframed illustration from a hobby to a profession. "It made me realize that being an illustrator is a real profession, just like any other." Fast-forward to today, and Sergio's client list reads like a who's who of publishing and design, from The New Yorker to Pentagram. While the calibre of collaborators has changed, what matters most remains the same: trust. "When a client trusts your work and approaches projects with an open mind, collaboration flourishes," he says. It's in these open, trusting relationships that Sergio finds the space to experiment and further develop his ideas. Unsurprisingly, editorial work holds a special place for him. "Editorial projects offer wider creative margins, allowing for greater flexibility and innovation," he explains. Compared to the tighter confines of advertising, editorial illustration offers the opportunity to tell nuanced stories, and Sergio is clear that he views every assignment, regardless of format, as a collaborative effort. If one thing is clear, though, it's that he's not that he's afraid to say no when needed. Maintaining a strong personal voice is non-negotiable. "I always strive to stay true to myself and ensure that every project I undertake reflects a clear personal signature," he says. For Sergio, authenticity isn't just a matter of artistic pride; it's what differentiates an illustrator in a saturated, increasingly automated industry. Valencia is home for Sergio, a city he credits with much of his creative energy. "Oh, Valencia! It's a beautiful city that inspires me and brings me joy," he says, describing it as a European cousin to Los Angeles with its sun-soaked streets and vibrant cultural scene. The blend of tradition and modernity fuels his practice, offering constant inspiration without the sensory overload that often accompanies larger creative hubs. Given the pressure many creatives feel to keep pace with shifting trends, Sergio's approach feels almost radical. "I'm not particularly interested in trends," he says. "What truly matters to me is the feeling of having done something meaningful and fulfilling by the end of the day." Instead of chasing what's fashionable, he draws inspiration from a surprisingly eclectic bookshelf, mixing everything from Wim Crouwel's graphic design classics to studies on Scandinavian tattoos and Alec Soth's photography. It's a reminder that fresh ideas rarely come from looking where everyone else is looking. In the era of AI and content overload, the role of the illustrator is changing, but Sergio remains optimistic. While machine learning might churn out images at record speed, it can't replicate the nuance and emotional intelligence that underpin great illustration. "Illustrators can tell stories, evoke emotions, and create meaningful connections that machines simply cannot replicate," he says. "Our role is shifting, but the value of authentic, thoughtful illustration remains indispensable." That insistence on authenticity carries through to the advice he offers younger illustrators navigating a commercial landscape. "Create work that makes you happy when you go to sleep at night," Sergio advises. "It's important to find projects that align with your values and passions so your artistic voice remains authentic." It's an ethos that has carried him through more than a decade of creative highs and industry shifts. Perhaps it's the real secret behind the clarity of his practice, which he has built not on chasing trends or algorithms but on careful craft, deliberate evolution, and the simple, enduring joy of a well-made pencil and a blank piece of paper.

Microsoft 365 Word gets SharePoint eSignature, now you can ditch third-party signing tools Paul Hill Neowin @ziks_99 · Jun 6, 2025 03:02 EDT Microsoft has just announced that it will be rolling out an extremely convenient feature for Microsoft 365 customers who use Word throughout this year. The Redmond giant said that you’ll now be able to use SharePoint’s native eSignature service directly in Microsoft Word. The new feature allows customers to request electronic signatures without converting the documents to a PDF or leaving the Word interface, significantly speeding up workflows. Microsoft’s integration of eSignatures also allows you to create eSignature templates which will speed up document approvals, eliminate physical signing steps, and help with compliance and security in the Microsoft 365 environment. This change has the potential to significantly improve the quality-of-life for those in work finding themselves adding lots of signatures to documents as they will no longer have to export PDFs from Word and apply the signature outside of Word. It’s also key to point out that this feature is integrated natively and is not an extension. The move is quite clever from Microsoft, if businesses were using third-party tools to sign their documents, they would no longer need to use these as it’s easier to do it in Word. Not only does it reduce reliance on other tools, it also makes Microsoft’s products more competitive against other office suites such as Google Workspace. Streamlined, secure, and compliant The new eSignature feature is tightly integrated into Word. It lets you insert signature fields seamlessly into documents and request other people’s signatures, all while remaining in Word. The eSignature feature can be accessed in Word by going to the Insert ribbon. When you send a signature request to someone from Word, the recipient will get an automatically generated PDF copy of the Word document to sign. The signed PDF will then be kept in the same SharePoint location as the original Word file. To ensure end-to-end security and compliance, the document never leaves the Microsoft 365 trust boundary. For anyone with a repetitive signing process, this integration allows you to turn Word documents into eSignature templates so they can be reused. Another feature that Microsoft has built in is audit trail and notifications. Both the senders and signers will get email notifications throughout the entire signing process. Additionally, you can view the activity history (audit trail) in the signed PDF to check who signed it and when. Finally, Microsoft said that administrators will be able to control how the feature is used in Word throughout the organization. They can decide to enable it for specific users via an Office group policy or limit it to particular SharePoint sites. The company said that SharePoint eSignature also lets admins log activities in the Purview Audit log. A key security measure included by Microsoft, which was mentioned above, was the Microsoft 365 trust boundary. By keeping documents in this boundary, Microsoft ensures that all organizations can use this feature without worry. The inclusion of automatic PDF creation is all a huge benefit to users as it will cut out the step of manual PDF creation. While creating a PDF isn’t complicated, it can be time consuming. The eSignature feature looks like a win-win-win for organizations that rely on digital signatures. Not only does it speed things along and remain secure, but it’s also packed with features like tracking, making it really useful and comprehensive. When and how your organization gets it SharePoint eSignature has started rolling out to Word on the M365 Beta and Current Channels in the United States, Canada, the United Kingdom, Europe, and Australia-Pacific. This phase of the rollout is expected to be completed by early July. People in the rest of the world will also be gaining this time-saving feature but it will not reach everyone right away, though Microsoft promises to reach everybody by the end of the year. To use the feature, it will need to be enabled by administrators. If you’re an admin who needs to enable this, just go to the M365 Admin Center and enable SharePoint eSignature, ensuring the Word checkbox is selected. Once the service is enabled, apply the “Allow the use of SharePoint eSignature for Microsoft Word” policy. The policy can be enabled via Intune, Group Policy manager, or the Cloud Policy service for Microsoft 365 Assuming the admins have given permission to use the feature, users will be able to access SharePoint eSignatures on Word Desktop using the Microsoft 365 Current Channel or Beta Channel. The main caveats include that the rollout is phased, so you might not get it right away, and it requires IT admins to enable the feature - in which case, it may never get enabled at all. Overall, this feature stands to benefit users who sign documents a lot as it can save huge amounts of time cumulatively. It’s also good for Microsoft who increase organizations’ dependence on Word.

Corsair Overhauls Prebuilt, 3-Chamber Airflow Case, & Transparent PSUJune 5, 2025Last Updated: 2025-06-05We take a look at Corsair’s upcoming i600 pre-built PC, Air 5400 case, Frame 4000D prototype, and moreThe HighlightsCorsair’s i600 pre-built PC is a new revision on the company’s i500 and overhauls its GPU cooler and CPU radiatorThe Corsair Air 5400 is an airflow-targeted case that has air ducts on the top and bottom of its chassisCorsair has partnered with Singularity to develop the Frame 4000D prototype, which has an interesting power board that handles cable managementTable of ContentsAutoTOC Grab a GN Tear-Down Toolkit to support our AD-FREE reviews and IN-DEPTH testing while also getting a high-quality, highly portable 10-piece toolkit that was custom designed for use with video cards for repasting and water block installation. Includes a portable roll bag, hook hangers for pegboards, a storage compartment, and instructional GPU disassembly cards.IntroWe visited Corsair’s suite at Computex 2025 and liked some of the stuff the company had to show. Editor's note: This was originally published on May 21, 2025 as a video. This content has been adapted to written format for this article and is unchanged from the original publication.CreditsHostSteve BurkeCamera, Video EditingMike GaglioneVitalii MakhnovetsWriting, Web EditingJimmy ThangCorsair Air 5400Corsair will release its Air 5400, which is an airflow-targeted case. On the back side of the case is a giant hole, which couples with a front-mounted radiator that will allow the case to shove air straight out of it. This design allows it to focus air flow for the GPU entirely from its own set of fans at the bottom of the case. This is probably the most interesting case from Corsair we saw at Computex this year. It should be around $220, though that’s dependent on the everchanging tariff situation. Internally, the Air 5400 has a duct at the bottom where the case has 3x120mm fans (the entire case is actually set up to support all 120mm fans, which simplifies things). The duct is there to guide air into the GPU. Corsair claims that the case is getting about a 1-2 degree improvement with the duct in a like-for-like test. If you do end up with a front radiator, then a potential area that gets abandoned in terms of airflow might be around the VRM area and some of the board components like system memory.  There are mounts for fans up on top of the case along with an additional duct. Looking at the back of the case, there are 2 holes on the back, which is surprising for a 120mm fan. The spacing doesn’t look like it would fit a 120mm fan, but Corsair’s plan is to include a bracket that would adapt a 120mm fan here and would actually cut out into the glass area on the back, which would make you lose about 40% of the fan. This should help but raises some questions about whether it may cause acoustic issues when you partially blast air into a glass wall. Speaking of glass, the Air 5400’s glass is laminated. A couple companies are doing this now. Corsair says this helps the glass stay more put together to prevent shattering. Looking at the back side panel, there’s a big acrylic sheet coupled with an area where air can escape. Opening up the back panel, there’s a huge amount of cable-management depth. You can also see that the motherboard tray is punctured all of the way through. This causes concerns around structural rigidity, but Corsair is using a .8mm thick steel, which helps a little bit here. The company has also strengthened the case’s top panel compared to Corsair’s 4000D case, which received negative feedback in that area. The Air 5400 is set to be priced at $220 with 3x120mm fans included. i600 Grab a GN15 Large Anti-Static Modmat to celebrate our 15th Anniversary and for a high-quality PC building work surface.

(or consider a direct donation or a Patreon contribution!)Corsair is updating its i500 pre-built PC, which we hated, with its upcoming i600, and the company has improved it a lot. The i500’s GPU cooling solution had basically no contact with any of the power components. The i600, on the other hand, has massive overhauls here. The case itself has only slightly changed, but the changes made accommodate larger radiators. The block for the video card, including the power components, is totally different in a way that looks promising. The stuff that jumped out to us right away about the i600 is the fin stacks for the VRM, which is connected to a shared copper nickel-plated base plate for the GPU and memory. Everything is connected to the same base plate, which is connected to the liquid cooler. This means all of the heat gets dumped into the liquid cooler. There’s pros and cons to this design. The pro is that all of the other components get cooled better. The downside is that the GPU itself is sharing the heat dissipation capacity with all of the other components in the cooler. This means you typically see some increase in the GPU temperature as a result. There’s ups and downs to this approach. It doesn’t necessarily mean one solution is better than the other as long as it’s all cooled. The i600 has copper bars, which contact the MOSFETs. Otherwise, it’s very similar to the i500. Corsair has also modified its CPU cooler radiator, where the company has moved its tanks off to the side. The tubes are also running in a different direction. Corsair is also moving to 25mm thick fans, where previously they had the slimmer 15mm fans. That extra 10mm will help with pressure and performance a lot. We plan on doing a review of the PC as soon as we buy one.Corsair Frame 4000DWe saw a prototype of Corsair’s Frame 4000D, where the company changed a few things. Corsair partnered with Singularity for its powerboard. It’s somewhat similar to Elmore’s BENCHLAB, with the exception of it not logging power. With the case, you basically run all of the power cables into the power board and then route them to their final locations. We count 10 fan headers here along with a bunch of RGB headers. There’s a lot of possibilities with this. Currently, it’s mostly being used as a cable-management tool, but you could, in theory, expand this to include more switches, like fan-control switches. We would really like to see current monitoring. It would make it more expensive but that could be a potentially useful direction to go in where you could monitor on the 12VHPWR, for instance, which would become a great marketing point for Corsair and would be very useful for end users. The front panel is also different as it has a die-cut edge now.  The power supply setup is also different here with Corsair doing an acrylic wall for the PSU instead of steel. The challenge here is that plastic is an incredibly good insulator. This could raise some ESD (electrostatic discharge) concerns and may cause the PSU to lose some of the shielding that steel provides. As a part of this design, Corsair has customized the caps and PCBs so that they get nice color matching. It looks pretty nice. 3D PrintingCorsair was telling us how for its upcoming 4000D and its Frame series cases, it was getting into 3D printable panels and pieces. They showed us how one Corsair employee 3D printed a shroud-like duct, which takes air in through the bottom and shoves it up into where the pump and reservoir are in the image above. These 3D print files are available on Corsair’s account on Printables.  Corsair 5000DWe didn’t care too much about it but Corsair also showed off its new 5000D that has a screen on it, which is a thing companies are doing now. They also had a 5000D case without the screen, which is a larger variant of the Frame 4000D case. Corsair says that it should be priced around $180, but that’s in flux with the tariffs situation.  Corsair Open Concept Visit our Patreon page to contribute a few dollars toward this website's operation (or consider a direct donation or buying something from our GN Store!)

The company showed a gigantic radiator tower at the show, which is pretty cool to see.

Email authentication protocols like SPF, DKIM, and DMARC play a critical role in protecting domains from spoofing and phishing. However, when SEGs are introduced into the email path, the interaction with these protocols becomes more complex. Security gateways(SEGs) are a core part of many organizations’ email infrastructure. They act as intermediaries between the public internet and internal mail systems, inspecting, filtering, and routing messages. This blog examines how security gateways handle SPF, DKIM, and DMARC, with real-world examples from popular gateways such as Proofpoint, Mimecast, and Avanan. We’ll also cover best practices for maintaining authentication integrity and avoiding misconfigurations that can compromise email authentication or lead to false DMARC failures. Security gateways often sit at the boundary between your organization and the internet, managing both inbound and outbound email traffic. Their role affects how email authentication protocols behave. An inbound SEG examines emails coming into your organization. It checks SPF, DKIM, and DMARC to determine if the message is authentic and safe before passing it to your internal mail servers. An outbound SEG handles emails sent from your domain. It may modify headers, rewrite envelope addresses, or even apply DKIM signing. All of these can impact SPF,  DKIM, or DMARC validation on the recipient’s side. Understanding how SEGs influence these flows is crucial to maintaining proper authentication and avoiding unexpected DMARC failures. Inbound Handling of SPF, DKIM, and DMARC by Common Security Gateways When an email comes into your organization, your security gateway is the first to inspect it. It checks whether the message is real, trustworthy, and properly authenticated. Let’s look at how different SEGs handle these checks. Avanan (by Check Point) SPF: Avanan verifies whether the sending server is authorized to send emails for the domain by checking the SPF record. DKIM: It verifies if the message was signed by the sending domain and if that signature is valid. DMARC: It uses the results of the SPF and DKIM check to evaluate DMARC. However, final enforcement usually depends on how DMARC is handled by Microsoft 365 or Gmail, as Avanan integrates directly with them. Avanan offers two methods of integration:1. API integration: Avanan connects via APIs, no change in MX, usually Monitor or Detect modes.2. Inline integration: Avanan is placed inline in the mail flow (MX records changed), actively blocking or remediating threats. Proofpoint Email Protection SPF: Proofpoint checks SPF to confirm the sender’s IP is authorized to send on behalf of the domain. You can set custom rules (e.g. treat “softfail” as “fail”). DKIM: It verifies DKIM signatures and shows clear pass/fail results in logs. DMARC: It fully evaluates DMARC by combining SPF and DKIM results with alignment checks. Administrators can configure how to handle messages that fail DMARC, such as rejecting, quarantining, or delivering them. Additionally, Proofpoint allows whitelisting specific senders you trust, even if their emails fail authentication checks. Integration Methods Inline Mode: In this traditional deployment, Proofpoint is positioned directly in the email flow by modifying MX records. Emails are routed through Proofpoint’s infrastructure, allowing it to inspect and filter messages before they reach the recipient’s inbox. This mode provides pre-delivery protection and is commonly used in on-premises or hybrid environments. API-Based (Integrated Cloud Email Security – ICES) Mode: Proofpoint offers API-based integration, particularly with cloud email platforms like Microsoft 365 and Google Workspace. In this mode, Proofpoint connects to the email platform via APIs, enabling it to monitor and remediate threats post-delivery without altering the email flow. This approach allows for rapid deployment and seamless integration with existing cloud email services. Mimecast SPF: Mimecast performs SPF checks to verify whether the sending server is authorized by the domain’s SPF record. Administrators can configure actions for SPF failures, including block, quarantine, permit, or tag with a warning. This gives flexibility in balancing security with business needs. DKIM: It validates DKIM signatures by checking that the message was correctly signed by the sending domain and that the content hasn’t been tampered with. If the signature fails, Mimecast can take actions based on your configured policies. DMARC: It fully evaluates DMARC by combining the results of SPF and DKIM with domain alignment checks. You can choose to honor the sending domain’s DMARC policy (none, quarantine, reject) or apply custom rules, for example, quarantining or tagging messages that fail DMARC regardless of the published policy. This allows more granular control for businesses that want to override external domain policies based on specific contexts. Integration Methods Inline Deployment: Mimecast is typically deployed as a cloud-based secure email gateway. Organizations update their domain’s MX records to point to Mimecast, so all inbound (and optionally outbound) emails pass through it first. This allows Mimecast to inspect, filter, and process emails before delivery, providing robust protection. API Integrations: Mimecast also offers API-based services through its Mimecast API platform, primarily for management, archival, continuity, and threat intelligence purposes. However, API-only email protection is not Mimecast’s core model. Instead, the APIs are used to enhance the inline deployment, not replace it. Barracuda Email Security Gateway SPF: Barracuda checks the sender’s IP against the domain’s published SPF record. If the check fails, you can configure the system to block, quarantine, tag, or allow the message, depending on your policy preferences. DKIM: It validates whether the incoming message includes a valid DKIM signature. The outcome is logged and used to inform further policy decisions or DMARC evaluations. DMARC: It combines SPF and DKIM results, checks for domain alignment, and applies the DMARC policy defined by the sender. Administrators can also choose to override the DMARC policy, allowing messages to pass or be treated differently based on organizational needs (e.g., trusted senders or internal exceptions). Integration Methods Inline mode (more common and straightforward): Barracuda Email Security Gateway is commonly deployed inline by updating your domain’s MX records to point to Barracuda’s cloud or on-premises gateway. This ensures that all inbound emails pass through Barracuda first for filtering and SPF, DKIM, and DMARC validation before being delivered to your mail servers. Deployment Behind the Corporate Firewall: Alternatively, Barracuda can be deployed in transparent or bridge mode without modifying MX records. In this setup, the gateway is placed inline at the network level, such as behind a firewall, and intercepts mail traffic transparently. This method is typically used in complex on-premises environments where changing DNS records is not feasible. Cisco Secure Email (formerly IronPort) Cisco Secure Email acts as an inline gateway for inbound email, usually requiring your domain’s MX records to point to the Cisco Email Security Appliance or cloud service. SPF: Cisco Secure Email verifies whether the sending server is authorized in the sender domain’s SPF record. Administrators can set detailed policies on how to handle SPF failures. DKIM: It validates the DKIM signature on incoming emails and logs whether the signature is valid or has failed. DMARC: It evaluates DMARC by combining SPF and DKIM results along with domain alignment checks. Admins can configure specific actions, such as quarantine, reject, or tag, based on different failure scenarios or trusted sender exceptions. Integration methods On-premises Email Security Appliance (ESA): You deploy Cisco’s hardware or virtual appliance inline, updating MX records to route mail through it for filtering. Cisco Cloud Email Security: Cisco offers a cloud-based email security service where MX records are pointed to Cisco’s cloud infrastructure, which filters and processes inbound mail. Cisco Secure Email also offers advanced, rule-based filtering capabilities and integrates with Cisco’s broader threat protection ecosystem, enabling comprehensive inbound email security. Outbound Handling of SPF, DKIM, and DMARC by Common Security Gateways When your organization sends emails, security gateways can play an active role in processing and authenticating those messages. Depending on the configuration, a gateway might rewrite headers, re-sign messages, or route them through different IPs – all actions that can help or hurt the authentication process. Let’s look at how major SEGs handle outbound email flow. Avanan – Outbound Handling and Integration Methods Outbound Logic Avanan analyzes outbound emails primarily to detect data loss, malware, and policy violations. In API-based integration, emails are sent directly by the original mail server (e.g., Microsoft 365 or Google Workspace), so SPF and DKIM signatures remain intact. Avanan does not alter the message or reroute traffic, which helps maintain full DMARC alignment and domain reputation. Integration Methods 1. API Integration: Connects to Microsoft 365 or Google Workspace via API. No MX changes are needed. Emails are scanned after they are sent, with no modification to SPF, DKIM, or the delivery path.  How it works: Microsoft Graph API or Google Workspace APIs are used to monitor and intervene in outbound emails. Protection level: Despite no MX changes, it can offer inline-like protection, meaning it can block, quarantine, or encrypt emails before they are delivered externally. SPF/DKIM/DMARC impact: Preserves original headers and signatures since mail is sent directly from Microsoft/Google servers. 2. Inline Integration: Requires changing MX records to route email through Avanan. In this mode, Avanan can intercept and inspect outbound emails before delivery. Depending on the configuration, this may affect SPF or DKIM if not properly handled. How it works: Requires adding Avanan’s Protection level: Traditional inline security with full visibility and control, including encryption, DLP, policy enforcement, and advanced threat protection. SPF/DKIM/DMARC impact: SPF configuration is needed by adding Avanan’s include mechanism to the sending domain’s SPF record. The DKIM record of the original sending source is preserved. For configurations, you can refer to the steps in this blog. Proofpoint – Outbound Handling and Integration Methods Outbound Logic Proofpoint analyzes outbound emails to detect and prevent data loss (DLP), to identify advanced threats (malware, phishing, BEC) originating from compromised internal accounts, and to ensure compliance. Their API integration provides crucial visibility and powerful remediation capabilities, while their traditional gateway (MX record) deployment delivers true inline, pre-delivery blocking for outbound traffic. Integration methods 1. API Integration: No MX record changes are required for this deployment method. Integration is done with Microsoft 365 or Google Workspace. How it works: Through its API integration, Proofpoint gains deep visibility into outbound emails and provides layered security and response features, including: Detect and alert: Identifies sensitive content (Data Loss Prevention violations), malicious attachments, or suspicious links in outbound emails. Post-delivery remediation (TRAP): A key capability of the API model is Threat Response Auto-Pull (TRAP), which enables Proofpoint to automatically recall, quarantine, or delete emails after delivery. This is particularly useful for internally sent messages or those forwarded to other users. Enhanced visibility: Aggregates message metadata and logs into Proofpoint’s threat intelligence platform, giving security teams a centralized view of outbound risks and user behavior. Protection level: API-based integration provides strong post-delivery detection and response, as well as visibility into DLP incidents and suspicious behavior.  SPF/DKIM/DMARC impact: Proofpoint does not alter SPF, DKIM, or DMARC because emails are sent directly through Microsoft or Google servers. Since Proofpoint’s servers are not involved in the actual sending process, the original authentication headers remain intact. 2. Gateway Integration (MX Record/Smart Host): This method requires updating MX records or routing outbound mail through Proofpoint via a smart host. How it works: Proofpoint acts as an inline gateway, inspecting emails before delivery. Inbound mail is filtered via MX changes; outbound mail is relayed through Proofpoint’s servers. Threat and DLP filtering: Scans outbound messages for sensitive content, malware, and policy violations. Real-time enforcement: Blocks, encrypts, or quarantines emails before they’re delivered. Policy controls: Applies rules based on content, recipient, or behavior. Protection level: Provides strong, real-time protection for outbound traffic with pre-delivery enforcement, DLP, and encryption. SPF/DKIM/DMARC impact: Proofpoint becomes the sending server: SPF: You need to configure ProofPoint’s SPF. DKIM: Can sign messages; requires DKIM setup. DMARC: DMARC passes if SPF and DKIM are set up properly. Please refer to this article to configure SPF and DKIM for ProofPoint. Mimecast – Outbound Handling and Integration Methods Outbound Logic Mimecast inspects outbound emails to prevent data loss (DLP), detect internal threats such as malware and impersonation, and ensure regulatory compliance. It primarily functions as a Secure Email Gateway (SEG), meaning it sits directly in the outbound email flow. While Mimecast offers APIs, its core outbound protection is built around this inline gateway model. Integration Methods 1. Gateway Integration (MX Record change required) This is Mimecast’s primary method for outbound email protection. Organizations route their outbound traffic through Mimecast by configuring their email server (e.g., Microsoft 365, Google Workspace, etc.) to use Mimecast as a smart host. This enables Mimecast to inspect and enforce policies on all outgoing emails in real time. How it works: Updating outbound routing in your email system (smart host settings), or Using Mimecast SMTP relay to direct messages through their infrastructure. Mimecast then scans, filters, and applies policies before the email reaches the final recipient. Protection level: Advanced DLP: Identifies and prevents sensitive data leaks. Impersonation and Threat Protection: Blocks malware, phishing, and abuse from compromised internal accounts. Email Encryption and Secure Messaging: Applies encryption policies or routes messages via secure portals. Regulatory Compliance: Enforces outbound compliance rules based on content, recipient, or metadata. SPF/DKIM/DMARC impact: SPF: Your SPF record must include Mimecast’s SPF mechanism based on your region to avoid SPF failures. DKIM: A new DKIM record should be configured to make sure your emails are DKIM signed when routing through Mimecast. DMARC: With correct SPF and DKIM setup, Mimecast ensures DMARC alignment, maintaining your domain’s sending reputation. Please refer to the steps in this detailed article to set up SPF and DKIM for Mimecast. 2. API Integration (Complementary to Gateway) Mimecast’s APIs complement the main gateway by providing automation, reporting, and management tools rather than handling live outbound mail flow. They allow you to manage policies, export logs, search archived emails, and sync users. APIs enhance visibility and operational tasks but do not provide real-time filtering or blocking of outbound messages. Since APIs don’t process live mail, they have no direct effect on SPF, DKIM, or DMARC; those depend on your gateway (smart host) setup. Barracuda – Outbound Handling and Integration Methods Outbound Logic Barracuda analyzes outbound emails to prevent data loss (DLP), block malware, stop phishing/impersonation attempts from compromised internal accounts, and ensure compliance. Barracuda offers flexible deployment options, including both traditional gateway (MX record) and API-based integrations. While both contribute to outbound security, their roles are distinct. Integration Methods 1. Gateway Integration (MX Record / Smart Host) — Primary Inline Security How it works: All outbound emails pass through Barracuda’s security stack for real-time inspection, threat blocking, and policy enforcement before delivery. Protection level: Comprehensive DLP (blocking, encrypting, or quarantining sensitive content)  Outbound spam and virus filtering  Enforcement of compliance and content policies This approach offers a high level of control and immediate threat mitigation on outbound mail flow. SPF/DKIM/DMARC impact: SPF: Update SPF records to include Barracuda’s sending IPs or SPF include mechanism. DKIM: Currently, no explicit setup is needed; DKIM of the main sending source is preserved. Refer to this article for more comprehensive guidance on Barracuda SEG configuration. 2. API Integration (Complementary & Advanced Threat Focus) How it works: The API accesses cloud email environments to analyze historical and real-time data, learning normal communication patterns to detect anomalies in outbound emails. It also supports post-delivery remediation, enabling the removal of malicious emails from internal mailboxes after sending. Protection level: Advanced AI-driven detection and near real-time blocking of outbound threats, plus strong post-delivery cleanup capabilities. SPF/DKIM/DMARC impact: Since mail is sent directly by the original mail server (e.g., Microsoft 365), SPF and DKIM signatures remain intact, preserving DMARC alignment and domain reputation. Cisco Secure Email (formerly IronPort) – Outbound Handling and Integration Methods Outbound Logic Cisco Secure Email protects outbound email by preventing data loss (DLP), blocking spam and malware from internal accounts, stopping business email compromise (BEC) and impersonation attacks, and ensuring compliance. Cisco provides both traditional gateway appliances/cloud gateways and modern API-based solutions for layered outbound security. Integration Methods 1. Gateway Integration (MX Record / Smart Host) – Cisco Secure Email Gateway (ESA) How it works: Organizations update MX records to route mail through the Cisco Secure Email Gateway or configure their mail server (e.g., Microsoft 365, Exchange) to smart host outbound email via the gateway. All outbound mail is inspected and policies enforced before delivery. Protection level: Granular DLP (blocking, encrypting, quarantining sensitive content) Outbound spam and malware filtering to protect IP reputation Email encryption for sensitive outbound messages Comprehensive content and attachment policy enforcement SPF: Check this article for comprehensive guidance on Cisco SPF settings. DKIM: Refer to this article for detailed guidance on Cisco DKIM settings. 2. API Integration – Cisco Secure Email Threat Defense How it works: Integrates directly via API with Microsoft 365 (and potentially Google Workspace), continuously monitoring email metadata, content, and user behavior across inbound, outbound, and internal messages. Leverages Cisco’s threat intelligence and AI to detect anomalous outbound activity linked to BEC, account takeover, and phishing. Post-Delivery Remediation: Automates the removal or quarantine of malicious or policy-violating emails from mailboxes even after sending. Protection level: Advanced, AI-driven detection of sophisticated outbound threats with real-time monitoring and automated remediation. Complements gateway filtering by adding cloud-native visibility and swift post-send action. SPF/DKIM/DMARC impact: Since emails are sent directly by the original mail server, SPF and DKIM signatures remain intact, preserving DMARC alignment and domain reputation.
