System Requirements

Your free Comodo Rules are configured and managed via our online interface
and only requires that they are downloaded to your web-server

  • » Apache web server v.2.2 and upward
    (Nginx and Lightspeed web servers also supported)
  • » Linux server platform
  • » 10 MB free space
    (to download free ModSecurity rule sets)
  • Optional: 2 MB free space for client installation

Why do you need a WAF?


Online enterprises are efficiently controlled by web applications. Online stores, payment gateways, dynamic content, web-mail and social media, banking transactions, etc. are controlled and managed by web application tools. Security data breaches lead to destruction and downfall of websites leading to loss of corporate financial data and sensitive personal information of the customers.


A WAF is focused chiefly in implementing ModSecurity rules and prompting on the intended updates regularly in response to the change in threat behaviors.


WAF and websites should be highly protected against online malicious threats and attacks. CWAF ensures effective protection of websites and applications that are running on Linux- and Apache-based web servers.
