About Holistic AI

Holistic AI sells an enterprise AI governance platform that lets customers discover every model, agent and application, assess AI risk and enforce policies.[1]

Holistic AI describes the problem as AI shipping faster than it can be governed. Its home page says new AI agents, LLMs and vendor tools go live every week, while AI inventory, risk assessments and compliance evidence still live in spreadsheets. The page also says that without AI discovery, nobody holds a complete and current inventory of what is actually running.[1]

The platform is organised around three layers: Identify, Protect and Enforce. The platform page says Identify continuously discovers and inventories every model, agent, API and pipeline across cloud, code and vendors, including shadow AI. The same page says Protect assesses, tests and red teams every system, from static models to multi-agent workflows. Enforce turns governance policy into enforceable workflows, maps controls to regulations, and generates audit-ready evidence on demand.[1]

On the risk side, the home page says the platform runs red teaming for prompt injection and jailbreaks, and 40+ tests for bias, hallucination, privacy and robustness. Holistic AI also says it monitors drift and performance in production. For agentic systems, Agent Graph maps the relationships among agents, tools, tasks and data so organizations can assess the system as a whole.[1][7]

Sentinel Agents monitor what an AI says in production, and Operative Agents step in inline when risk crosses a defined threshold. The platform page says enforcement runs inline via the HAI Guardian SDK.

For deployment, Holistic AI says its integrations are read-only and need no agents to install.

Holistic AI also offers an independent audit under the Digital Services Act.[5]

Holistic AI began at University College London, where Dr Adriano Koshiyama and Dr Emre Kazim set out to solve the governance problem. Its stated mission is to empower enterprises to adopt and scale AI with confidence.[6]

The trust center also says Holistic AI does not use customer data to train models.[1][5][6][8][9]
