Web Application Firewall (WAF) is a security tool that operates at the application layer, designed to protect web requests and responses from common attacks. A good WAF can shield your web apps from threats like SQL injection, cross-site scripting (XSS), and other vulnerabilities. It can also monitor and block traffic that might lead to Denial of Service (DoS) attacks.
