Sublime Security

Sublime Security is a programmable, AI-powered cloud email security platform for Microsoft 365 and Google Workspace that detects and responds to email threats such as phishing, business email compromise (BEC), and malware using a transparent, rules-based engine. Unlike legacy "black box" secure email gateways, it allows security teams and the broader community to write, share, and customize open-source detection rules, operationalize threat intelligence, and auto-triage user-reported emails.
