Hi Martijn,
Specifically I'm trying to forward logs for Harmony Endpoint (Managed via the Infinity Portal), as our SIEM doesn't currently have an API integration for Endpoint.
I'm trying here...

At the top MSSP level this works great, but it fails to connect when I do this at a tenant level.
I suspect I need the license. $300 for the license is a little disappointing when virtually every other vendor has syslog as a standard feature. I presume I'd need a license per tenant? That's going to get expensive for what is free in other products 🙄
