About Obsidian Security

Obsidian Security provides cybersecurity technology designed for the AI-first enterprise, with a focus on securing data, AI systems and non-human identities operating inside third party applications.

The company helps security teams understand what is connected to enterprise systems, determine what those identities and agents are allowed to access, and monitor their activity in real time.

Obsidian says non-human identities already outnumber human identities 144 to 1 in third-party applications, while the rapid adoption of AI agents is further expanding this security challenge.

Core offerings include:

AI-agent security and governance
Non human identity security
Third party application protection
Runtime monitoring and policy enforcement

Leadership Comments

“AI is fundamentally changing how enterprises operate creating new infrastructure challenges that legacy security models weren’t designed to address,” said Jun Hong Heng, Founder and Chief Investment Officer of Crescent Cove Advisors. “Obsidian recognized that shift early and is building the platform enterprises need to securely adopt AI at scale.

AI agents gravitate toward third party applications. Thats where the data lives, that’s where the work happens, and that's exactly where the risk lives too," said Hasan Imam, CEO of Obsidian Security. Frontier, and open source models alike are pushing agents deeper into these environments faster than most security teams can track.
