WitnessAI

WitnessAI develops an enterprise AI security and governance platform for employees, AI models, applications and autonomous agents. It discovers AI usage, observes prompts and responses, enforces identity- and intent-based access policies, controls agent connections to tools and MCP servers, and provides audit trails. Its runtime defenses help prevent sensitive-data leakage, prompt injection, jailbreaks and harmful outputs; the platform also supports AI spending analysis and model routing. Based in Mountain View, California, WitnessAI helps organizations deploy and use AI with security and compliance controls.
