Witness AI

WitnessAI is an AI security and governance platform that lets enterprises safely deploy and manage AI across their workforce. Its platform spans three pillars: Observe (visibility into all AI activity, shadow-AI discovery, and cataloging of applications and agents), Control (governance policies, audit trails, and compliance across human and AI workforces), and Protect (runtime security that blocks prompt injection and jailbreaks and filters harmful outputs). It addresses data leakage, prompt-injection attacks, unauthorized agent activity, and compliance gaps. The company is backed by GV. As of this profile no public API, developer portal, or SDKs are published; engagement is via sales/demo.
