Cloudflare announces Firewall for AI

What this post added

Introduces Firewall for AI, a new protection layer for Large Language Models (LLMs). This feature extends existing WAF capabilities like Rate Limiting and Sensitive Data Detection to address LLM-specific threats such as prompt injection, data exfiltration, and model denial of service. It analyzes user prompts to identify and block abuse attempts before they reach the LLM, and can be deployed in front of models hosted on Cloudflare Workers AI or other infrastructures.
