Take control of public AI application security with Cloudflare's Firewall for AI

Cloudflare announces the open beta of Firewall for AI, an inline security solution that discovers LLM-powered endpoints, detects PII in prompts using regex and Presidio-based NER running on Workers AI, and enforces protections via WAF rules and Security Analytics. The solution identifies LLM endpoints through traffic heuristics (e.g., SSE, response bitrate) and integrates with custom and rate-limiting rules to block or allow specific PII categories, with planned enhancements including token counting and AI-driven guardrails.
