APERION is the runtime governance layer for enterprise AI agents in regulated industries. The company builds the Enterprise AI Trust Fabric: verified identity, runtime governance, and identity-bound audit evidence, so financial services, healthcare, and defense organizations can deploy AI agents and prove to regulators what every one of them did. Its on-premises control plane, SmartFlow, enforces policy inline on every prompt, response, and tool call. Its open-source middleware, Shield, governs agent tool calls. APERION composes with existing identity and access platforms rather than replacing them.
