Cloudflare’s layered security approach combines multiple security practices into one service. It prevents disruptions caused by bad bots, while allowing the good bots, such as Google web crawlers through, keeping Internet assets highly available, protected, and performant.
Simply choose the security setting that’s right for your website. Cloudflare shields you with a complete layer of defense, including a built-in Web Application Firewall (WAF), to stop attacks of all types and sizes. Cloudflare even protects you from the toughest attacks targeting Layer 3/4 and 7.
