With access to the HTTP and HTTPS traffic streams, the WAF can now analyse the passing traffic to identify and mitigate rogue and malicious content.

What is difference between WAF and firewall?

Understanding the Difference Between Application and Network-level Firewalls. A WAF protects web applications by targeting Hypertext Transfer Protocol (HTTP) traffic. … A network firewall protects a secured local-area network from unauthorized access to prevent the risk of attacks.
