Robust Intelligence vs Promptfoo

Both compete in Red-Teaming & AI Security. Robust Intelligence positions itself as “AI Firewall and automated model validation to secure AI from build to production”, while Promptfooleads with “Open-source tool for evaluating and red-teaming LLM apps, agents, and RAG systems”. The table below compares what each publishes.

Where Robust Intelligence pulls ahead

Publishes support for NIST AI RMF, which Promptfoo does not. Enterprise security and ML risk teams wanting adversarial testing plus runtime protection mapped to AI-security standards

Where Promptfoo pulls ahead

Developer teams wanting free, open-source, CI/CD-integrated evaluation and red teaming of LLM apps

Best forEnterprise security and ML risk teams wanting adversarial testing plus runtime protection mapped to AI-security standardsDeveloper teams wanting free, open-source, CI/CD-integrated evaluation and red teaming of LLM apps
LimitationsAbsorbed into Cisco, so it is increasingly delivered as Cisco AI Defense rather than a standalone product; enterprise-oriented, less accessible to small teamsDeveloper-oriented and requires engineering effort to configure; broader governance/compliance features live in the paid enterprise tier.

Which should you shortlist?

Choose Robust Intelligence if enterprise security and ML risk teams wanting adversarial testing plus runtime protection mapped to AI-security standards

Choose Promptfoo if developer teams wanting free, open-source, CI/CD-integrated evaluation and red teaming of LLM apps

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