I'm going to get log from my firewall ，in order to see more firewall information in my splunk enterprise 7.2.0 web-site,especially compliance（eg：HIPPA SOX PCI-DSS，etc） information.
But my firewall is produced by a unpopular company，not Cisco ASA、check point、fortigate etc， I can't find any add-on or app for my device in splunkbase.
so what add-on/app should I use?
If the firewall supports sending syslog, you can setup a syslog-ng or rsyslog on a linux server (VM could do) to receive the logs and parse them to files/folder structure. You may then have to do custom TA to extract fields for your needs.
