LimitationsSecurity- and red-teaming-first orientation means it emphasizes threat testing and monitoring over deep policy/GRC workflow; enterprise pricing is not publicly listed; still a relatively young company with limited publicly named customers.Now part of A10 Networks, so future roadmap is tied to the acquirer; standalone framework/compliance mapping is limited publicly.

Which should you shortlist?

Choose Cranium AI if enterprises that need to secure, red-team, and prove governance across internal and third-party AI in one platform

Choose TrojAI if enterprises wanting combined pre-deployment red teaming and runtime AI application protection

Neither is a substitute for a governance program. Whichever you pick, you still need people who can define the policies the tool enforces.
