By standalone server, we mean any server with or without a control panel other than cPanel, Directadmin or Plesk. The same one-line command used above can be used for instaling cPGuard on all servers. But, since the environements can vastly differ from one to another, you will be asked to provide additional infomation manually during the installation.

cPGuard offers two license types, each tailored to the number of accounts on your server. The Standard license accommodates up to 50 users, while the Unlimited accounts license imposes no user restrictions.
Our support spans various web hosting control panels and platforms, with user counting based on the total number of users on the server, irrespective of the active users in the control panel.

Sometimes your license may show errors especially when your IP address is changed. So in such cases, you need to re-issue the license to register your new instance for the license key.

To start with let us discuss what is inotify :- Inotify (inode notify) is a Linux kernel subsystem that acts to extend filesystems to notice changes to the filesystem, and reports those changes to applications through the APIs provided. This particular subsystem support was added to Glibc version in 2006; to use inotify, you must have a Linux machine with kernel 2.6.13 or later.Inotify Watch helps to keep track of the file changes under the directories on “watch” and report back to the application in a standard format using the API calls.
Obviously, it does not make any direct harm to the system. For a 64-bit system, 1 kB memory will be allocated for each watch on board. So with sufficient memory, increasing the watch will be just fine and we have crafted our application to utilize the memory as efficiently as possible.

Absolutely! There's no binding contract, giving you the freedom to cancel your cPGuard plan whenever you need. No strings attached!
