Our AI agents work like a digital SOC team in your environment, triaging and blocking advanced threats while adapting protections at adversary speed. It provides full transparency and automation by default, with control on demand for advanced teams, eliminating vendor bottlenecks or one-size-fits-all limits. Core Outcomes (The What): - Stop More Attacks with Fewer False Positives - block sophisticated threats (BEC, novel phishing, QR-based phishing) and reduce the false positives that waste time and disrupt workflows. Our tailored protections deliver a demonstrably higher catch rate, validated by the world's most demanding security teams. - Automate the Abuse Mailbox - Our Autonomous Security Analyst (ASA) automates triage, investigation, and remediation of user-reported email, cutting MTTR from hours to seconds and freeing your SOC team to focus on the threats that matter most. - Adapt Defenses Automatically. - When a missed attack is identified, we can create new coverage in hours. Our Autonomous Detection Engineer (ADÉ) generates, backtests, and deploys org-specific coverage, eliminating vendor ticket limbo. Differentiators (The How): - A Team of Agents using AI, Not Just a Black Box - Sublime deploys a team of specialized agents - like an analyst and a detection engineer - that use AI to protect, triage, and adapt your defenses. Unlike an opaque, monolithic AI, our agentic approach provides full transparency into every action, with visible decision history, message lineage, and backtests. - Org-Specific Protection, Not One-Size-Fits-All - Our Distributed Detection Model (DDM) is the foundation of our platform. It runs per-environment coverage that adapts to the unique attacks you face, allowing us to safely deploy protections that would be noisy in global models - something centralized systems simply can’t support. This means higher day-one efficacy and fewer false positives. - Autonomous by Default, Control on Demand - By stopping more attacks and reducing false positives, Sublime delivers a superior autonomous experience that requires less work. For advanced teams, the platform is fully extensible, allowing you to author your own detections and hunt for threats with a level of precision that one-size-fits-all solutions can't. Innovative organizations including Spotify, Snowflake, Brex, Elastic, Compass, Anduril, SentinelOne, and others rely on Sublime to secure the business and keep teams focused on strategic defense. 🔗 Learn how Sublime helps security teams stop more attacks with less work at sublime.security * * * Product Website Sublime Email Security Platform Seller [Sublime Security](https://www.g2.com/sellers/sublime-security) Discussions [Sublime Email Security Platform Community](https://www.g2.com/products/sublime-email-security-platform/discuss) Solution Type Best-of-Breed Overview by Christine Huynh Show More ## Value at a Glance Averages based on real user reviews. ### Time to Implement 2 months [ View More Pricing Information ](https://www.g2.com/products/sublime-email-security-platform/pricing) ## Sublime Email Security Platform Integrations (4) What do users say about integrations?

Senior Email Engineer Enterprise (\> 1000 emp.) 2/11/2026 "Accurate Out of the Box, Transparent Detections, and Powerful Automations" 5/5 What do you like best about Sublime Email Security Platform? I like that Sublime has a high degree of accuracy out of the box negating a long tuning process. The regular updates to existing and creation of new core detections keeps us well protected. The ability to create custom detection, create bespoke automations is a massive plus point. I like that the detection logic is transparent, so you always know why something was flagged. The API features also make it simple to integrate into existing workflows and remove repetitive manual tasks. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? Sublime develops and releases new valuable features regularly that we would love to use. Unfortunately, inconsistencies in regional hosting outside of the direct control of Sublime can mean that sometimes these valuable new features don’t appear in our region right away. Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you? Sublime greatly strengthens our overall detection stack by adding defence in depth, its automated remediation of threats and it's automated analysis and remediation of user‑reported phishing significantly reduces manual investigation time whilst maintaining or improving response quality.

I appreciate how user-friendly both the UI and API of the Sublime Email Security Platform are, which allows me to create in-depth detections and automations easily. I like that Sublime MQL facilitates deep customization when creating detection rules, capturing specific scenarios with various email attributes. The platform provides complex detection rule creation that would be challenging with other solutions, and it's impressive how the functions in MQL allow for intricate rule construction, down to prevalence within the configured tenant. The powerful language of Sublime provides extensive coverage with its rules, which is another aspect I find valuable. Review collected by and hosted on G2.com.

RC Rob C. IT Cloud Security Engineer 2/9/2026 "Advanced Threat Protection with Stellar Support" 5/5 What do you like best about Sublime Email Security Platform? I really like that the Sublime Email Security Platform is simple to use and very customizable, which is important for our large and sometimes complex organization. We love that the engineers are also the support team and are always happy to help, whether by jumping on a call or messaging in Teams. It's easy and straightforward to manage, thanks to this hands-off approach where it basically does everything itself. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? The only thing I can think of is there's a feature that only processes data in the US (ADE and the ability to automatically share emails with Sublime), whereas we need everything to be processed in the UK. It's just very key for us that everything's in the UK. Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you?

AM Andrew M. 12/29/2025 "Enterprise-Level Security, Effortless Onboarding" 5/5 What do you like best about Sublime Email Security Platform? I like that the Sublime Email Security Platform feels like an enterprise product and it was really easy to onboard our Google Workspaces account, all for free. I appreciate how it helps filter out malicious and spam content, while also allowing us to whitelist customer email domains and craft specific rules. The comprehensive rules make decision-making straightforward. Additionally, reviewing actions taken by the system has become an important internal security process to ensure we reduce false positives. The platform's interactive wizard automated our setup process, making it very easy to get started, and it feels very complete for the price point, especially since we're under the threshold for free use. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? It takes a little bit of trial and error to learn how to apply actions to the 700+ built-in rules, I would of appreciated some additional help/guidance on setting up rule actions from within the console. Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you? I use Sublime Email Security Platform for inbound email security, anti-phishing, anti-spam, filtering malicious content, whitelisting domains, and creating specific rules.

What stands out most about Sublime is how effectively it combines best-in-class email protection with exceptional usability. The platform does a great job of blocking phishing, malware, and other advanced threats without impacting user experience — false positives are minimal, and legitimate communications flow without friction. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? Overall the experience has been positive Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you? Sublime Email Security Platform is solving several key challenges in our email security stack — especially around advanced threat detection, phishing resistance, and policy enforcement. Before Sublime, it was harder to tailor protections to specific user groups and unique risk scenarios in our organization. The platform’s customizable rules engine has been a game-changer — it allows us to define precise policies that align with our business needs and security posture, such as rules based on sender behavior, attachment characteristics, internal user risk profiles, or domain spoofing patterns. This flexibility means that we can block or quarantine high-risk email types proactively, while reducing false positives for trusted communications. As a result, we’ve seen fewer successful phishing attempts, faster incident response, and less noise for our security team, which in turn improves operational efficiency. The ability to fine-tune rules without waiting for vendor intervention has also helped us stay agile as threats evolve. Overall, Sublime helps us protect our users more effectively, cut down on security overhead, and enforce consistent policies that match our risk tolerance — all while maintaining email usability for the business.

Information Security Manager Mid-Market (51-1000 emp.) 8/29/2025 "Best-in-Class Security Platform" 5/5 What do you like best about Sublime Email Security Platform? The platform is incredibly intuitive, giving us full visibility into email threats without complex setup or management. The dashboards and alerting make it easy to stay ahead of attacks. The ability to customize detection rules and workflows is a huge plus. We’re not locked into a one-size-fits-all product—it adapts to our environment. We were able to connect Google Workspace and start seeing results in less than 10 minutes. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? Sublime's Message Query Language (MQL) is powerful and incredibly useful for creating detection rules and automations, but it does require some trial and error and time spent with documentation to be able to use it to its full potential. Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you? We are solving a number of issues with Sublime: - The Google Workspace-native email security tools are cumbersome to use and don't provide much visibility into why something was flagged. Sublime provides a lot of detail on attack signals and message details, allowing our Security team to analyze potential threats faster. - Sublime's detection of malicious emails is very good. During our first week, a number of employees received a well crafted phishing email that Google did not detect, but Sublime flagged it as malicious instantly. - Sublime allows us to automate the response to malicious emails, which reduces the risk to end users and saves Security teams valuable time.

JH John H. Enterprise Platforms & Services - Senior Email Engineer Enterprise (\> 1000 emp.) 6/6/2025 "Reliable detection out of the box, unrivalled support, transparency and endless customisation." 5/5 What do you like best about Sublime Email Security Platform? I'm a big fan of the transparency of the platform and how you can see the what, the why, the how a threat was detected and prevented. The limitless ability to tune and customize detections to provide the best coverage for our organisation (whilst still providing reliable coverage right out of the box). Initial deployment is a piece of cake.... In just a few clicks you are ingesting historic data and detecting threats. Another stand-out to me is the excellent slack community where you can not only engage directly with the Sublime team for support but where other customers can share ideas, detections and threats they have seen. Review collected by and hosted on G2.com. What do you dislike about Sublime Email Security Platform? I find it hard to offer criticism of Sublime as any "dislikes" I had have been addressed by Sublime since we became a customer. If I had to be pressed I would like to see some improvement in the native reporting abilities of the platform and the capability to export these reports for consumption. Review collected by and hosted on G2.com. What problems is Sublime Email Security Platform solving and how is that benefiting you? Sublime has been a game-changer in tackling advanced email threats.
