Checkpoint devices don't seem to really like syslog, but we do have an integration using their Opsec NG applications.
There is a Checkpoint connector for syslog messages from Checkpoint EdgeX listed as "Checkpoint Edge X Firewall". It is possible it may work with the one you are asking about. Sometimes venders use the same core messages for other brands of their devices. If that one does not work then your best bet is to put in a Connector Feature Request for that coverage. I would highly suggest that you also put a Thwack request that others can vote up as well. The more requests we get for a device the higher it gets moved up in the priority list.
