Update configuration | ESET Server Security

Select default update profile

Choose existing or create new profile that will be applied by default for updates.

Clear update cache

If you experience problems with an update, click Clear to clear the temporary update cache.

Product updates / Auto-updates

Enabled by default. Use the slider to disable auto-updates if you need to stop the ESET Server Security from being updated temporarily. We recommend that you keep this setting enabled to ensure your ESET Server Security has the latest Program Component Updates (PCU), and micro Program Component Updates (μPCU) applied when a new update is available.

The updates are applied after the next server restart.

Outdated detection engine alerts

Set maximum detection engine age automatically / Maximum detection engine age (days)

Use the slider to disable automatic detection engine age and set the maximum time manually (in days) after which the detection engine age will be reported as out of date. The default value is 7.

Module Rollback

If you suspect that a new update of detection engine and/or program modules may be unstable or corrupt, you can rollback to the previous version and disable updates for a set period of time. Alternatively, you can enable previously disabled updates if you had postponed them indefinitely. ESET Server Security records snapshots of detection engine and program modules for use with the Rollback feature. To create detection engine snapshots, leave Create snapshots of modules enabled.

Number of locally stored snapshots

Defines the number of previous module snapshots stored.

Rollback to previous modules

Click Rollback to revert program modules to previous version and temporarily disable updates.

To create a custom update profile, select Edit next to List of profiles. Type your own Profile name and click Add. Select profile to edit and modify parameters for module updates types or create an Update mirror.

Select the type of update to use from the drop-down menu:

•Regular update - By default, the Update type is set to Regular update to ensure that update files will automatically be downloaded from the ESET server with the least network traffic.

•Pre-release update - Are updates that have gone through thorough internal testing and will be available to the general public soon. You can benefit from enabling pre-release updates by having access to the most recent detection methods and fixes. However, pre-release updates might not be stable enough at all times and SHOULD NOT be used on production servers and workstations where maximum availability and stability is required.

•Delayed update - Allows updating from special update servers providing new versions of virus databases with a delay of at least X hours (that is, databases tested in a real environment and therefore considered as stable).

Enable update delivery optimization

When enabled, update files are downloaded from CDN (content delivery network). Disabling this setting may cause download interruptions and slowdowns when dedicated ESET update servers are overloaded. Disabling is useful when a firewall is limited to access ESET update server IP addresses only or a connection to CDN services is not working.

Ask before downloading update

When a new update is available, you will be prompted before downloading it.

Ask if an update file size is greater than (KB)

If the update file size is greater than the value specified in the field, a notification will be displayed.

Modules updates

Module updates are set to Choose automatically by default. The update server is the location where updates are stored. If you use an ESET server, we recommend that you leave the default option selected.

When using a local HTTP server - also known as a Mirror - the update server should be set as follows: http://computer_name_or_its_IP_address:2221
When using a local HTTP server with SSL - the update server should be set as follows: https://computer_name_or_its_IP_address:2221
When using a local shared folder - the update server should be set as follows: \\computer_name_or_its_IP_address\shared_folder

Enable more frequent updates of detection signatures

Detection engine will be updated in shorter intervals. Disabling this option may negatively impact detection rate.

Allow module updates from removable media

Update from removable media if contains created mirror. When Automatic selected, updates will run in the background. If you want to show update dialogs select Always ask.

Product updates

Pausing auto-updates for specific update profiles temporarily disables automatic product updates, for example while connected to the internet using other networks or metered connections. Keep this setting enabled to have constant access to the latest features and the highest possible protection.

In some cases, a server restart may be required for the updates to take place.

Proxy Server

To access the proxy server setup options for a given update profile, click the Proxy mode and select one of the three following options:

•Do not use proxy server - No proxy server will be used by ESET Server Security when performing updates.

•Use global proxy server settings - Proxy server configuration specified in the Advanced setup (F5) > Tools > Proxy server will be used.

•Connection through a proxy server - Use this option if:

A proxy server should be used to update ESET Server Security that is different from the proxy server specified in the global settings (Tools > Proxy server). If so, the settings should be specified here: Proxy server address, communication Port (3128 by default), plus Username and Password for the proxy server if required.
The proxy server settings were not set globally, but ESET Server Security will connect to a proxy server for updates.
Your computer is connected to the internet via a proxy server. The settings are taken from Internet Explorer during program installation, but if they are subsequently changed (for example, if you change your ISP), check that the HTTP proxy settings listed in this window are correct. Otherwise the program will not be able to connect to the update servers.

Authentication data such as Username and Password is intended for accessing the proxy server. Complete these fields only if a Username and Password are required. Please note that these fields are not for your Username/Password for ESET Server Security, and should only be completed if you know you need a password to access the internet via a proxy server.

Use direct connection if proxy is not available

If a product is configured to utilize HTTP Proxy and the proxy is unreachable, the product will bypass the proxy and communicate directly with ESET servers.

Windows shares

When updating from a local server running Windows, authentication for each network connection is required by default.

Connect to LAN as

To configure your account, select one of the following options:

•System account (default) - Use the system account for authentication. Typically, no authentication process takes place if there is no authentication data supplied in the main update setup section.

•Current user - Select this option to ensure that the program authenticates using the currently logged-in user account. The drawback of this solution is that the program is not able to connect to the update server if no user is currently logged in.

•Specified user - Select this option to use a specific user account for authentication. Use this method when the default system account connection fails. Be aware that the specified user account must have access to the update files directory on the local server. If the user does not have access, the program will not be able to establish a connection or download updates.

When either Current user or Specified user is selected, an error may occur when changing the identity of the program to the desired user. We recommend entering the LAN authentication data in the main update setup section. In this update setup section, the authentication data should be entered as follows: domain_name\user (if it is a workgroup, enter workgroup_name\name) and password. When updating from the HTTP version of the local server, no authentication is required.

Disconnect from server after update

To force a disconnect if a connection to the server remains active even after updates have been downloaded.

Configuration options for the local Mirror server are located in the Advanced setup (F5) in the Update > Profiles > Update Mirror tab.
