About
Sublime Security is a next-generation email security platform that uses autonomous AI agents to detect, adapt, and respond to advanced threats — including BEC, phishing, malware, and QR code attacks — in hours rather than days. Security teams gain full visibility, a detection-as-code rule engine, and an open-source threat intelligence layer to hunt and stop attacks before they reach users.
