About

Prompt Security is a comprehensive platform for securing enterprise AI. It prevents Shadow AI and data exposure risks from third-party tools and copilots, protects homegrown AI apps from threats like prompt injections, jailbreaks, and toxic outputs, and manages the sprawl of AI agents. By inspecting every prompt and response, it provides full visibility, enforces policy, and ensures governance across all AI interactions in the organization.
