Innovation Matrix Assessment

Very early-stage, small team; broad operational deployment is unproven publicly.
Acquired by identity unicorn Silverfort in April 2026 to anchor its AI-era runtime identity security roadmap.
Runtime, AI-agent-inclusive authorization is a forward-looking approach ahead of most static, policy-based IAM tools.
No independent efficacy data found for a company only about a year old at acquisition.
Runtime identity and access decisions for humans, machines, and AI agents is a fast-growing enterprise security need.
