About

WitnessAI is an AI security and governance platform founded in 2023 and headquartered in California. The company was built to address a critical enterprise blind spot: as employees and business units adopt AI tools at an accelerating pace — often without IT or security approval — organizations lack the visibility, control, and auditability needed to manage how AI is being used with sensitive data. WitnessAI's founding thesis is that AI governance must be built as dedicated infrastructure, not bolted onto existing security tools, to handle the unique risks introduced by generative and agentic AI systems.\n\nThe platform provides unified discovery of shadow AI usage across an organization, policy enforcement for approved AI tools, real-time monitoring of AI interactions for data leakage and compliance violations, and governance controls for agentic AI workflows that operate autonomously on behalf of users. WitnessAI integrates with enterprise identity providers, SaaS platforms, and security information systems to give CISOs and compliance teams a centralized view of AI risk. Its agentic AI governance capabilities address the emerging challenge of AI agents taking consequential actions within enterprise systems without adequate human oversight.\n\nWitnessAI raised $58 million in January 2026 and has achieved over 500% ARR growth, reflecting the urgency enterprises feel around AI governance as regulatory scrutiny and data breach risks from AI misuse intensify. The company competes in the rapidly forming AI security category alongside Nightfall AI, Securiti, and emerging offerings from established security vendors. Its early mover advantage, purpose-built architecture, and focus on agentic AI governance differentiate it as enterprises move beyond basic acceptable-use policies toward enterprise-grade AI governance frameworks.
