How Do WAFs Work?

Web Visitor

WAFs inspect HTTP/HTTPS packets and filters malicious traffic

Your Website

What is a Web Application Firewall (WAF)?

Web Application Firewalls inspect all incoming and outgoing web traffic and it intelligently blocks the potential web attacks before they reach your web server. WAFs carefully inspect all Application Layer (OSI Model Layer 7) traffic and only allow legitimate traffic through to a web server.

Benefits of WAFs:
  • Cleaner & safer network : mitigate major hacking incidents
  • Peace of mind : always active security that works on the perimeter
  • Performance : security that doesn’t affect performance or incur latency issues
  • Compliance : satisfy PCI-DSS requirement 6.6

Why You Should Choose CodeGuard Backup?

Most WAF vendors utilize an open source WAF engine called ModSecurity (which has no GUI). These vendors typically build a front facing user interface or dashboard and only add basic signatures or pattern matching rules on top of ModSecurity. This can be an issue for a variety of reasons since pattern matching only relies on known attacks or attacks that have already happened in the past. This makes users vulnerable to modified web attacks or even unknown or new attacks. QatarCloud completely flips the script in terms of security technology with its patented logic analysis engine. This intelligent engine automates the web attack detection process by utilizing more behavioral symptoms of malicious attacks (QatarCloud don't only rely on pattern matching).
