Enterprise AI Security and Governance for Humans and Agents

WitnessAI, incubated by Ballistic Ventures in 2023 and led by CEO Rick Caccia (former SVP of Marketing at Palo Alto Networks), builds an enterprise AI governance platform that puts guardrails around how employees and agents use generative AI models. The company raised $27.5 million in a Series A from Google Ventures and Ballistic Ventures in May 2024, followed by $58 million in strategic funding led by Sound Ventures in January 2026. The WitnessAI platform intercepts traffic between users and LLMs, applies policies to prevent data leakage, blocks prompt injection and misuse, and gives security and privacy teams detailed visibility into all AI activity — delivered via isolated, per-customer cloud instances designed for regulatory separation and millisecond latency.

Enterprise AI adoption is outpacing governance. Employees interact with AI models across dozens of tools and platforms, generating conversations that may include sensitive corporate data, regulated information, or policy violations that go completely unmonitored. WitnessAI addresses this by acting as an invisible governance layer between the enterprise and all AI systems — cataloguing AI systems in use, tracking every interaction for intent and behavioral patterns, enforcing data protection policies, and blocking prompt injection and model jailbreaking attempts in real time. The platform is designed specifically for security and privacy teams who need to enable AI productivity without accepting ungoverned risk, delivering compliance evidence alongside operational controls in a single system.
