⚡ Web Application Firewalls

Web Application Firewalls (WAF) are security solutions that inspect and filter incoming HTTP and HTTPS requests before they reach a web application.

They use rule sets to detect and block common threats such as SQL injection and cross-site scripting, and include capabilities for bot mitigation, DDoS protection, API security, virtual patching, and rate limiting.

According to our research, web application firewalls are detected on 2.5% of all websites.
97.8% of these sites use only one WAF technology, 2.2% use two.
