Armorer Labs

Armorer Labs is a Y Combinator-backed company providing continuous security verification and runtime protection for AI agents. Its platform assesses agent risks, reproduces attacks, drafts fixes, and verifies that protections work without disrupting legitimate tasks. Armorer Guard enforces approved rules before agents act, helping block unsafe operations such as exports prompted by untrusted web content. Engineers retain control: they review and approve changes, which can be delivered through draft pull requests and merged by the team.

The platform maps findings to frameworks including the OWASP Agentic and LLM Top 10, MITRE ATLAS, and the NIST AI Risk Management Framework. It also provides security alerts through Slack and connects with tools such as GitHub, MCP, Claude Code, and OpenCode. Armorer publishes benchmark results for its detection models and shares threat intelligence about real-world risks to AI agents. The company describes its lightweight screening model as running on CPU, with an approximately nine-millisecond first-stage decision time.
