“Being named to the Fortune Cyber 60 is both an honor and a motivation,” said Josh Kamdjou, CEO and co-founder of Sublime Security. “Email protection requires a fundamentally new strategy as autonomous and AI-enhanced attacks continue to evolve. With our agentic AI technology, we’re giving defenders unprecedented tools to outsmart adversaries and reshape the future of email security.”
The recognition follows Sublime Security’s successful $150 million Series C funding round completed in October 2025. Earlier this year, the company also debuted its first two intelligent AI agents — Autonomous Security Analyst (ASA) and Autonomous Detection Engineer (ADÉ) — designed to automate and expand core security operations for enterprises facing relentless threat volumes.
