About HiddenLayer

HiddenLayer inventories AI apps and models, scans the artifacts they rest on, then red-teams and guards them in production. Runtime sits as a firewall that watches prompts, tool calls, and agent sessions without needing the customer's training data.

Air-gapped packaging is aimed at classified and disconnected shops that cannot send model traffic to a SaaS broker.
