cPGuard is a malware scanner rated as light, fast and powerful.

  • cPGuard automatically detects and stops viruses, malware, spyware, redirects and symlinks before they affect you and your customers.
  • cPGuard uses a very modest amount of resources to operate with the power it brings.
  • When malicious files are detected, cPGuard automatically sends the infected files to OpsShield‘s cloud-based analytics engine and pushes the cleaned file back to the server.
  • cPGuard also provides simple, easy-to-use and customizable configurations such as: adding folders to monitor, adding users, folders or files you don’t want to whitelist.

In addition to the above main features, cPGuard also provides other advanced features such as:

  • Require Captcha to secure login page.

  • Provides ModSecurity principles for Webhosting servers.
