OPNsense App (Opnsense_App_for_Splunk)


This Splunk App is community driven and not affiliated with the official OPNsense® Firewall. As such, the included documentation does not contain information on how to get started with this firewall. Rather, this documentation serves as a guide to help visualize the data in Splunk. Please visit for documentation on installing/configuring your own OPNsense firewall.

The OPNsense App for Splunk helps make your firewall data meaningful. Visualize system or security related events recorded by the OPNsense® Firewall. This app requires the OPNsense Add-on for Splunk.

Key Features
