Best AI Security Testing Tools 2026
When you’re evaluating safeguards for AI systems, compare what each tool lets you test: custom cases, data leakage, jailbreaks, prompt injection, and unsafe outputs. Deployment mode, API-independent access details such as a free plan, and paid-from pricing can help narrow options to fit your environment and budget. Among the named tools are F5 BIG-IP APM, Project Moonshot, and AgentScan, with OpenSecureAI Scanner, PromptGuard, Augustus, Basilisk, and Giskard also represented. Consider which threat behaviors you need to examine and whether the available deployment and pricing details suit your development workflow.
