Opsin
Opsin is a San Jose-based enterprise AI security company that helps organizations adopt generative AI tools like Microsoft Copilot, ChatGPT Enterprise, Claude, and Google Gemini without leaking sensitive data. Its platform continuously maps AI agents across the enterprise, assesses what data those agents can surface, detects oversharing and policy violations in real time, and remediates misconfigurations - giving security, GRC, and legal teams visibility and control within about 24 hours of a one-click API integration.
