Sublime Security Platform

Sublime Security delivers an adaptive, AI-powered cloud email security platform that fundamentally changes how organizations protect against email threats by combining superior effectiveness with unprecedented visibility and control. Unlike traditional black-box solutions, Sublime provides explainable detection logic where security teams can see the reasoning behind every detection and result, while maintaining the ability to customize detection policies for their specific environment without vendor dependency. The platform is built on a multi-agent AI system featuring ASA (Autonomous Security Analyst) that triages suspicious or user-reported emails with behavioral analysis based on TTPs, and ADÉ (Autonomous Detection Engineer) that analyzes attack patterns to write, test, and validate new coverage, cutting detection timelines from weeks to hours.

Sublime protects against the full range of email threats including sophisticated BEC (Business Email Compromise), novel phishing attacks, GenAI-powered spear phishing, malware delivery, account takeover, and insider threats. The platform detects threats with high precision while providing automated triage, investigation, and remediation of user-reported messages, cutting MTTR from hours to seconds. Key capabilities include Attack Surface Reduction (ASR) for email, behavioral analysis using the proprietary Message Query Language (MQL), threat-hunting capabilities, and comprehensive automation that eliminates busywork for security teams.

The platform integrates with Microsoft 365 and Google Workspace and provides full visibility across the entire messaging ecosystem. Sublime offers both a Core (free) tier with community detections and basic capabilities, and an Enterprise tier with custom detections, advanced automation, attack surface reduction, priority support, and the full multi-agent AI system. The company maintains strong community engagement with approximately 200 published detections including 70+ community contributions. While specific compliance certifications are not publicly listed, Sublime complies with the EU-U.S. Data Privacy Framework and maintains a trust center for security documentation.
