Kerio Control Offline License File Work [ Linux ]

The offline license file is a critical asset. If an attacker gains read access to the firewall configuration backup or the appliance file system, they can harvest the license file. While the file is bound to the Hardware ID, possession of the file allows an attacker to provision a cloned appliance (MAC address spoofing) if they can manipulate hardware identifiers.

Since your Kerio Control instance cannot reach the internet, you must use a separate computer with web access to obtain the file. Visit the Kerio Product Registration page. Kerio Control Offline License File
