CloudFlare has introduced a firewall specifically designed for AI, called Firewall for AI, which primarily serves enterprises deploying AI models, aiming to provide a protective layer. The AI firewall, being a WAF, is used to intercept potential vulnerabilities and illegal exploitation issues, such as MDoS and sensitive information leaks. CloudFlare's AI firewall reduces the risk of MDoS through rate limiting, thereby decreasing the risk of business interruptions for enterprises.
