Product activation

You are prompted to activate your product when the installation is complete.


You can use any of the following methods to activate ESET Server Security:

A purchased License Key

Type or copy/paste your ESET-issued License Key into the License Key field and click Continue. Type the License Key exactly as it is, including the hyphens. If you copy/paste the license, ensure that you do not accidentally select additional space around the text.

ESET Business Account

Use this option if you are registered and have your ESET Business Account where your ESET Server Security license has been imported.

An offline License file

This is an automatically generated file that is transferred to the ESET product. Your offline License file is generated from the license portal and is used in environments where the application cannot connect to the licensing authority.

Click Activate later with ESET PROTECT if your computer is a member of a managed network, and your administrator will perform remote activation via ESET PROTECT. You can also use this option if you want to activate this client later.

Select Help and support > Change license in the main program window to manage your license information. You will see the public license ID used to identify your product and license. Your Username, under which the computer is registered, is stored in the About section, and you can view it by right-clicking the Windows notification area icon TRAY_ICON.

After successfully activating ESET Server Security, the main program window opens and displays your current status on the Monitoring page. Some attention may be required initially; for example, you are asked if you want to be part of ESET LiveGrid®.

The main program window also displays notifications about other items, such as system updates (Windows Updates) or detection engine updates. When everything requiring attention is resolved, the monitoring status turns green and displays the status You are protected.

You can activate your product from the main menu under Help and support > Activate Product or Monitoring status > Product is not activated.


ESET PROTECT can silently activate client computers using licenses made available by the administrator.
