Updated
In short: AgentSeal is ranked #1 of 27 as of 3 October 2026, ahead of OpenSecureAI Scanner and Promptfoo. The best-ranked option with a free plan is OpenSecureAI Scanner. The lowest first paid tier on this page is RedFang at $19/mo.
AI red teaming tools help teams test AI systems against potential weaknesses. The ranking begins with AgentSeal, ProofLayer, and Darkhunt AI Security, followed by Promptfoo and Confident AI. Compare target systems and attack categories, then consider the level of automation and support for custom tests. Deployment options and continuous monitoring can help distinguish how tools fit into an evaluation process, while report exports matter for sharing findings. Free-plan availability and paid-from pricing are included too. Use these criteria to compare the listed capabilities with the systems you need to assess and how you plan to run tests.
