Web Application Firewall (WAF)
Protection against OWASP Top 10, SQL injection, XSS
Cloudflare WAF protects web applications against the most common attacks, including all OWASP Top 10 categories, blocking more than 136 billion threats daily. It uses machine learning trained on traffic from over 57 million requests per second to identify zero-day exploits and unknown attack vectors.

Rules can be customized using Firewall Rules with Wireshark-like expressions.
