A Web Application Firewall (WAF) can process much more complex rules than a standard firewall, specifically for HTTP (web application) traffic. Generally, these rules cover common attacks such as cross-site scripting (XSS) and SQL injection. A WAF is specifically designed for HTTP traffic, enabling extensive rule customization; attacks can be identified and blocked, protecting your traffic.
It's important to note that a WAF is not a replacement for a firewall or IDS/IPS, as it only protects HTTP traffic. It is a required component of most compliance standards if your data or systems can be accessed through a web-based application.
