Firewall for AI is an inline security solution that protects user-facing LLM-powered applications from abuse and data leaks. It integrates directly with Cloudflare’s Web Application Firewall (WAF) to provide instant protection with zero operational overhead, automatically discovering and enforcing AI guardrails throughout the entire request lifecycle. The beta release includes capabilities such as discovery, detection of sensitive information disclosure, mitigation of security controls, and more features will follow in future releases. By leveraging Cloudflare Workers AI, Presidio's Named Entity Recognition model, and other technologies, Firewall for AI aims to strengthen LLM security, prevent sensitive data exposure, and reduce the risk of social engineering attacks.
