Guardion

Guardion (GuardionAI) is an early-stage AI-security company building a runtime control plane that governs enterprise AI agents. Designed with a zero-trust architecture for regulated industries, the platform routes agent traffic through an encrypted gateway that sits directly in the execution path, where it can discover and inventory agent activity, detect prompt attacks, redact sensitive data, block data leakage, and enforce security and compliance policies across multi-step agent workflows. It is positioned as a drop-in proxy between AI tools and the systems they touch, giving teams instant observability, inline enforcement, and compliance coverage without re-architecting applications. The company advertises operational reliability aimed at production use, including a 99.99% gateway uptime SLA on distributed infrastructure with automatic failover and low added latency (P99 under roughly 20ms of overhead). Founded in 2024 by former Apple Siri runtime-security engineers and organized in Dover, Delaware, Guardion is a small, recently formed startup, and detailed funding information is not publicly disclosed. It is aimed at security, risk, and compliance teams in regulated sectors that are deploying autonomous or semi-autonomous AI agents and need runtime governance, data protection, and auditability at the point where agents act.
