About Sonrai Security

Sonrai maps every identity-to-permission relationship, then deploys organization-level deny policies that strip unused privileged actions, services, and regions. Just-in-time access comes back through Slack or Teams so a blocked call does not become a Sev-1 for DevOps.

Independent testing in 2025 showed the firewall blocked 16 of 16 AWS privilege-escalation paths without a proxy in the data plane.
