WitnessAI

Platform that observes and controls how employees and AI agents use AI tools across the network.

WitnessAI sits in the network path to give enterprises visibility into AI usage, applying policy based on what a person or agent is trying to do rather than just which tool they reached. Security and governance teams use it to enable AI adoption while blocking risky prompts and data flows. Founded in 2023, it has raised over $85M.
