Best Web Application Firewall (WAF) Software

Web application firewalls (WAF) are designed to protect web apps by filtering and monitoring incoming traffic. These tools analyze HTTP traffic as it comes in, blocking potentially malicious traffic and identifying traffic anomalies. Companies use these tools in conjunction with additional application security software to better protect operational web applications. These tools differ from traditional firewalls, which control traffic between servers, by filtering traffic and content attempting to access a specific web-based application.

To qualify for inclusion in the Web Application Firewalls (WAF) category, a product must:

  • Inspect traffic flow at the application level
  • Filter HTTP traffic for web-based applications
  • Block attacks such as SQL injections and cross-site scripting
