AI agent security platform that maps intent, identity, data and access
Opsin (Opsin Security) is a San Jose enterprise AI security company that discovers employee-built AI agents across tools such as Microsoft Copilot, Claude, ChatGPT Enterprise and Gemini, then maps each agent's purpose, identity, permissions, data and tools against its behavior. Its risk graph helps security teams prioritize and remediate excess access and off-mission actions. In October 2026 it raised a $21 million round led by SYN Ventures and Race Capital. Founders include James Pham (CEO), Oz Wasserman (CPO) and Jeremy Mailen (CTO), with backgrounds at Abnormal Security, FireEye and Trifacta.
