Product activation

When installation is complete, you will be prompted to activate your product.


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

Enter a License Key

A unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the the license owner and for activation of the license.

ESET Business Account

Use this option if you are registered and have your ESET Business Account (EBA) exlink where your ESET Server Security license has been imported. You can also enter Security Admin credentials that you use on ESET License Administrator portal exlink.

Offline License file

An automatically generated file that will be transferred to the ESET product to provide license information. 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 at a later time.

Select Help and support > Manage license in the main program window to manage your license information at any time. You will see the public license ID used to identify your product by ESET and for license identification. Your Username, under which the computer is registered, is stored in the About section, which you can view by right-clicking the system tray icon TRAY_ICON.

After you've successfully activated ESET Server Security, the main program window will open and display your current status in the Monitoring page. Some attention may be required initially, for example, you'll be asked if you want to be part of ESET LiveGrid®.

The main program window will also display notifications about other items, such as system updates (Windows Updates) or detection engine updates. When all items that require attention are resolved, the monitoring status will turn green and display 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 is able to activate client computers silently using licenses made available by the administrator.
