AI red teaming is an essential adversarial testing process that challenges AI systems, particularly language models and agents, to identify vulnerabilities such as prompt injection, data leakage, and other unsafe behaviors before real-world exploitation occurs. OWASP ranks prompt injection as the top risk for LLM applications, emphasizing the need for rigorous testing. Various tools like Promptfoo, Garak, and TestMu AI offer different approaches to red teaming, from CI/CD integration and broad probe sweeps to real-time agent testing. Choosing the right tool depends on the deployment surface, whether it targets model endpoints or live conversational agents, and the specific risks an organization faces. While tools like Promptfoo and Garak provide extensive testing capabilities for models, TestMu AI uniquely focuses on live agent interfaces, assessing readiness across multiple attack categories. In regulated environments, reporting and evidence quality are crucial, and for systems with actionable capabilities, addressing Excessive Agency is vital to prevent financial repercussions.
