WitnessAI

The confidence layer for secure enterprise AI.

WitnessAI is an AI security and governance platform that provides a unified layer for securing enterprise AI adoption, including agent-to-agent communication. It’s built for large enterprises across regulated and high-stakes industries that need visibility and control over how AI systems and agents interact with data and each other. Rather than building AI models itself, WitnessAI sits as a governance layer across whatever AI systems an organization already uses. The company reports raising over $85M in total funding and 500% ARR growth, figures the company itself has disclosed.

Key Features

Unified AI governance layer — Provides centralized visibility and control across an organization’s AI usage, rather than securing one model or tool at a time.
Agent-to-agent communication security — Monitors and secures interactions between AI agents, not just human-to-AI interactions.
Enterprise AI interaction monitoring — Tracks how employees and systems interact with AI to flag risk or policy violations.
Model-agnostic design — Operates as a security layer independent of which underlying LLM providers an enterprise uses.

Use Cases

For regulated enterprises — A financial services firm uses WitnessAI to monitor and govern employee and agent interactions with AI tools to meet compliance requirements.
For large industrial organizations — A utility or automaker secures multi-agent workflows across its operations without needing to vet each individual AI vendor separately.
