Web Application Firewall (WAF) is a security solution designed to protect web applications from common threats by filtering and monitoring HTTP traffic between a web application and the Internet, blocking malicious traffic and allowing legitimate traffic to pass through.

Additionally, the WAF is capable of identifying bots and controlling attacks automatically, without requiring any action from the client. This security system protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among other threats.
