Products in this niche protect artificial intelligence systems by intercepting prompts, screening for sensitive data leaks, and blocking jailbreaks or prompt injections. They are primarily purchased by engineering, security, and compliance teams deploying generative AI applications into production. Unlike general application security tools or standard LLM observability platforms, these solutions specifically enforce runtime safety rules, validate tool calls, and sanitize context windows to prevent adversarial exploits.

This theme's recent-window count is below the current min-count filter, so it does not appear in the opportunity scorecard.
