Holistic AI is the control layer for enterprise AI. The governance gap is no longer theoretical. AI systems are making decisions, taking actions, and interacting with real-world systems right now, at a speed and scale no human review process can match. The risk is not in your next audit. It is happening at runtime. Holistic AI gives enterprises the infrastructure to govern AI where it actually operates, built around three pillars: Identify. Automatically detect every AI system across your organization, built, bought, or embedded. Surface shadow AI, third-party tools, and hidden deployments before they become blind spots. Protect. Continuously test for bias, risk, and compliance against global frameworks including the EU AI Act, NIST AI RMF, and ISO 42001. Catch what static reviews miss, before and after deployment. Enforce. Apply policies directly to AI systems and intervene the moment risks emerge, activating controls, blocking unsafe behavior, and generating audit-ready evidence without slowing operations down. Recognized by Gartner as a Representative Vendor in the emerging category of Guardian Agents, and trusted by enterprises including Unilever, Siemens, and MAPFRE, Holistic AI is building the governance infrastructure that AI at scale actually requires. The organizations moving fastest on AI are the ones who stopped treating governance as a checkpoint and started treating it as a control system.
