Hlyn is building the control layer for AI agents.

We combine application-level intent enforcement with kernel-level containment — intercepting every tool call, isolating every runtime, and stopping compromised agents from escaping their boundaries.

Our system understands both what an agent is trying to do and what it is actually doing at the OS level. The result is full-stack containment for autonomous systems, built for the era of agentic infrastructure.

We also built the best open-source prompt injection detector on HuggingFace — 95.8% precision, 6.4× faster inference than the nearest competitor (protect ai), and a free API.
