Choosing the right LLM red teaming tool depends on the specific lifecycle improvements a team needs, whether it's generating attacks, evaluating immediate responses, or managing ongoing evaluation and release processes. Tools like Garak, Braintrust, Promptfoo, PyRIT, DeepTeam, and Mindgard each offer unique strengths, such as flexible open-source scanning, comprehensive known-risk evaluation, configuration-first workflows, custom multi-turn campaigns, ecosystem integration, and managed security services. Garak excels in attack discovery with its broad probe library, while Braintrust focuses on maintaining confirmed attacks as versioned evaluations. Promptfoo offers a command-line tool that covers both scanning and evaluation, and PyRIT provides adaptive attack strategies for complex scenarios. DeepTeam integrates with DeepEval for seamless adoption within existing ecosystems, and Mindgard offers a managed platform for automated AI security testing. Teams can benefit from combining tools to leverage their strengths across different stages of the security testing process, ensuring comprehensive coverage and maintaining a cohesive evaluation workflow.
