About Hush Security

Hush treats every AI agent as an identity that needs an owner and an expiry date.

It discovers coding assistants, enterprise agents, and self-hosted agents, including ones that never pass through a gateway, along with the MCP servers and tools they reach.

Each agent is registered to an accountable human, standing credentials are removed, and access is brokered just in time for a single action, scoped by both the agent's limits and the permissions of the person it acts for.

Every action is logged and a central kill switch can stop an agent. The company started in secrets and service accounts, and Kyndryl is a named customer and reseller.
