Cloudflare’s enterprise-class web application firewall (WAF) protects your Internet property from common vulnerabilities like SQL injection attacks, cross-site scripting, and cross-site forgery requests with no changes to your existing infrastructure.

Self-managed WAFs quickly become outdated and require professional service hours to regularly update rules to protect against new threats. Cloudflare’s WAF helps you stay ahead of threats by automatically updating when new security vulnerabilities are released. Rules created by Cloudflare in response to new threats are responsible for mitigating the vast majority of threats on our network.

Cloudflare offers a single source of control for the security of websites, applications, and APIs, hosted across multiple cloud environments. Multi-cloud security provides visibility into security events, while allowing for consistent security controls, across all clouds in which Internet assets are deployed. Any attack traffic seen by Cloudflare is recorded and analyzed. Cloudflare’s network then shields Internet assets across all cloud providers.
