WitnessAI
Observe, control, and protect employees, models, apps, and agents from one AI security plane.
Proof of life. Raised $58M led by Sound Ventures, January 2026
WitnessAI catalogs shadow AI, MCP servers, and agents, then applies intent-based policies rather than keyword DLP. Runtime blocks jailbreaks and prompt injection on the way in and filters unsafe output before a user or an agent acts on it. Agent actions can be attributed back to a human identity, which is the audit trail most Copilot and coding-agent rollouts still lack.
