Best AI security tools for security teams

48 tools · last reviewed 2026-07

Where security owns AI risk, the requirement shifts from documenting oversight to demonstrating testing. These tools speak the security organisation's language — findings, severities, reproductions, CI gates — and map to references like the OWASP LLM Top 10 and MITRE ATLAS rather than to management-system clauses.

How to choose

Favour tools that integrate into existing pipelines and ticketing, and that produce findings an application security engineer can triage without AI expertise.
