CDN WAF Intro

A Web Application Firewall (WAF) can offer critical protection for any online business that must securely handle private customer data. Businesses typically deploy a WAF to shield their web applications from sophisticated and targeted attacks, like cross-site scripting (XSS) and SQL injection. A WAF sits between a company’s web applications and the requests coming in from the internet. Via reverse proxy, it monitors, filters, or blocks data packets as they travel to and from a web application. In doing so, it attempts to screen out potentially harmful traffic that may enable web exploits.
