### [Sublime Email Security Platform](https://www.g2.com/products/sublime-email-security-platform/reviews)

Sublime’s agentic platform stops more email attacks with less work. 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
