Beta: Imunify360 version 4.5 released

Jan 6, 2020 6:50:23 PM / by Inessa Atmachian



We’re pleased to announce that the new version of Imunify360, our automated security application for Linux servers, has been released. This new version, 4.5, includes three new features that make it even more flexible and effective.

Stand-alone installation
Previously, Imunify360 had to be installed through a particular control panel, such as cPanel, DirectAdmin, or Plesk. Now, with version 4.5, it can be installed directly on the server, independent of any panel, regardless of the administrative interface.


We invite panel developers, VPS and shared hosting companies to integrate with Imunify360 in order to start using a comprehensive automated security solution on servers and add more value to the hosting service in general. Contact our product team via feedback@imunify360.com for details. We’ll be happy to assist you.

Global IP management
Now it’s possible to combine several servers into a management group, and manage IPs within that particular group. Just log in with your CLN account, create groups, add some servers to them, and you can block/whitelist particular IPs among the servers in those groups.



Improved PAM module
The PAM plugin for Imunify360 (“Pluggable Authentication Module”) now provides protection for Exim+Dovecot components against brute-force IMAP/POP3 attacks. It counts the number of unsuccessful attempts, and identifies the targets as single- or multiple-user accounts and considers the source of attacks, so it blocks attackers in a more intelligent way.

In addition to these features, we’ve also improved the performance and efficiency of Imunify360 in version 4.5: its malware scanner and other components now require less CPU and memory.
