Obsidian Security Raises $85 Million at $1.1 Billion Valuation

Obsidian Security, a company that manages AI agent security, has raised $85 million in funding at a $1.1 billion valuation. The company provides a platform that monitors and controls what AI agents (software programs that can perform tasks autonomously) are allowed to access and do within business systems like databases and customer relationship managers, blocking risky actions like privilege escalation (gaining unauthorized higher-level access) and unauthorized data access in real time. The new funding will help Obsidian expand its security controls for Claude Code and Cowork, popular AI agents that need governance to prevent misuse.
