Syslog server

If you have a Syslog server running in your network, you can Export logs to Syslog to receive certain events (Detection Event, Firewall Aggregated Event, HIPS Aggregated Event, etc.) from client computers running ESET Endpoint Security.

To enable the Syslog server:

1.Click More > Settings > Syslog and click the toggle next to Enable Syslog sending.

2.Specify the following mandatory settings:

a.Format of payload:—JSON, LEEF or CEF

b.Format of envelope of the log—BSD (specification), Syslog (specification)

c.Minimal log levelInformation, Warning, Error or Critical

d.Event type of logs—Select the type of logs you want to include (Antivirus, HIPS, Firewall, Web protection, Audit Log, Blocked files, ESET Inspect alerts).

e.Destination IP or FQDN of TLS-compatible syslog server—IPv4 address or hostname of the destination for Syslog messages

f.Validate CA Root certificates of TLS connections—Click the toggle to enable the certificate validation for the connection between your Syslog server and ESET PROTECT. After enabling the validation, a new text field will be displayed where you can copy and paste the required certificate chain. The server certificate must meet the following requirements:

The whole certificate chain in PEM format is uploaded and saved in the Syslog export configuration (this includes root CA, as there are no built-in trusted certificates)

Your Syslog server's certificate provides a Subject Alternative Name extension (DNS=/IP=), in which at least one record corresponds to the FQDN/IP hostname configuration.


You need the certification authority version 3 (and later) with the Basic Constraints certificate extension to pass the validation.

The validation of TLS connections applies only to the certificates. Disabling the validation does not affect the TLS settings of ESET PROTECT.

After making the applicable changes, click Apply settings. The configuration becomes effective in 10 minutes.


The regular application log file is constantly being written to. Syslog only serves as a medium to export certain asynchronous events, such as notifications or various client computer events.
