### Sublime Email Security Platform

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

### [AegisAI Security](https://www.g2.com/products/aegisai-security/reviews)

AegisAI is an API-based email security platform purpose-built for Microsoft 365 and Google Workspace. The platform utilizes autonomous AI agents to evaluate inbound mail across identity signals, sender behavior, and language intent. This multi-layered analysis enables the detection of highly sophisticated threats that often bypass traditional security gateways, specifically AI-powered spearphishing, compromised vendor accounts, and complex business email compromise (BEC). Rather than relying on static signatures, AegisAI analyzes user intent in every interaction. By understanding the unique communication patterns between specific senders and recipients, the platform identifies the subtle anomalies—such as shifts in urgency, tone, or phrasing—that signal a hijacked conversation or an impersonation attempt. Deployment is lightweight and non-disruptive, connecting directly via mail APIs without requiring MX record changes or altering mail flow. Beyond advanced social engineering, AegisAI provides comprehensive, native protection against phishing, malicious attachments, and zero-day malware. Its self-learning model also functions as an intelligent filter to neutralize persistent spam and promotional noise, ensuring a clean and secure inbox for both general users and high-target executives. This specialized filtering reduces the "alert fatigue" that often distracts SOC teams from high-priority security events. AegisAI leverages agentic investigation to secure every layer of the inbox, providing a robust defense against Account Takeover (ATO) attempts and Data Loss Prevention (DLP) risks. Unlike traditional tools that rely on basic reputation checks, AegisAI provides security teams with advanced AI forensics and actionable intelligence. Every detection—from a suspicious file to a subtle impersonation attempt—is supported by a clear evidence trail. This allows SOC teams to resolve the specific "blind spots" found in modern social engineering while maintaining total visibility into the evolving trust dynamics of their organization. By deploying a self-configuring control plane, AegisAI automates the remediation process, ensuring that once a threat is identified, it is neutralized across the entire enterprise instantly.
