What they do

Problem

AI agents accessing tools and production systems can execute unsafe or unauthorized actions due to weak identity, access control, and auditing.

Solution

A zero-trust identity, authentication, and fine-grained authorization platform that wraps every agent tool call with parameter-level verification, policy guardrails, ephemeral credentials, and real-time audit logging.

Who it's for

Engineering and security teams building and operating AI agent workflows in organizations needing strict access control and compliance.
