    What is Web Application Firewall?

    A Web Application Firewall (WAF) filters, monitors and blocks bad HTTP traffic targeting vulnerabilities in web applications. It helps your business stay up and running by protecting your website and apps from sophisticated attacks, including cross-site scripting (XSS), SQL injection (SQLi) and large-scale distributed denial of service (DDoS).
