Witness AI

Witness AI builds a unified platform for enterprise AI security and governance. The product operates at the network level, giving organisations visibility into AI activity across their workforce, including the detection of shadow AI usage - tools and models adopted without formal approval. It applies intent-based access controls that interpret context rather than matching keywords, and provides runtime security for models, applications and AI agents. Deployment is via network integration or lightweight APIs, and the system blocks novel threats and filters harmful outputs before they reach users.

The platform's architecture is single-tenant, designed to address data-sovereignty requirements. Technical work spans several areas: network-level visibility and monitoring, runtime protection for models and agents, intent-based access control, shadow AI detection, and data-loss prevention and output filtering. Customers include global enterprises in industries such as airlines and financial services.

Founded in 2023, the company has raised $58 million in strategic funding and was named to the Fortune Cyber 60 list.
