The end-to-end AI governance platform to discover, assess, mitigate, monitor and govern risk across every AI agent, model, and application.
Holistic AI provides an enterprise AI governance platform that unifies discovery, testing, monitoring, and compliance into a single system. The platform automatically discovers AI systems including shadow AI across cloud, code, data, and SaaS, maintains a live inventory, and tracks ownership and lifecycle. It offers continuous automated testing for bias, hallucinations, toxicity, privacy leaks, drift, security vulnerabilities like jailbreaks and adversarial attacks, along with runtime monitoring via workflow tracing and observability. Policy-as-code enforcement aligns with regulations, providing deployment gates, audit trails, and evidence collection for compliance reporting. Serving enterprises in regulated sectors, it distinguishes itself with comprehensive coverage from AI inventory to real-time agentic monitoring and policy enforcement at scale, backed by research origins at University College London.Holistic AI homepage, Holistic AI governance platform, Holistic AI about, Preqin profile, LinkedIn, CB Insights
