Sublime Security

Sublime Security is a modern email security platform that gives security teams transparency and control over how email threats are detected and blocked. Unlike black-box gateways, it combines AI-driven detection with a programmable rules language, letting teams write, tune, and share custom detections for phishing, business email compromise, malware, and emerging attacks. This adaptability helps organizations catch novel threats that static, native email defenses miss.

Sublime deploys via API alongside Microsoft 365 and Google Workspace, providing deep visibility into email attacks, automated response, and a community of shared detection rules. Its open, transparent approach appeals to security teams that want to understand and improve their email defenses rather than trust a closed system. Sublime Security is designed for security teams that want adaptive, programmable, AI-powered email protection with full visibility and control.
