Integrates with any LLM and supports both input and output validation.
Wiz is the dominant cloud security platform and the leader in AI Security Posture Management (AI-SPM).

Wiz identifies misconfigurations, exposed models, and sensitive training data risks across the entire AI supply chain. As the most widely adopted cloud security platform, Wiz is the de facto standard for securing enterprise AI infrastructure.
