Is it possible for me to have Glasswire Premium (OR Portmaster --alt. to Glasswire) running with CIS 2024 Beta ?
Glasswire/Portmaster aren’t security firewalls. They’re more for filtering and seeing all the active connections under the hood in real time.
I mentioned cruelsister because I like how she explains and demonstrates things, as well as her use of sarcasm as a second language. 
An interesting question, and to answer I doid a quickie test run of both vs CF.
Of the 2 I would suggest GlassWire over PortMaster (the latter doesn’t always play nice with CF). With regard to Glasswire, it has a very pretty interface, and if you find value in the non-malware related Network Monitoring thingies it would be fine.
However I was rather surprised that a modified Coinminer had the abilityto connect out the BlackHat Command without showing up in the Netwrok activity screen- but note that I used the free version (with the Paid version all Outbound connections would be handled similarly (but more annoyingly) to CF with the Firewall in Custom Ruleset mode.
Hope this helped!

Having Portmaster & CIS on your PC at the same time will require a powerful PC configuration, as these 2 programs are demanding in terms of resources.
Personally, I don’t see the functional benefit of having both.
In terms of filter rules, with Portmaster you can do a lot of what CFW does, but I find it less flexible, more cumbersome and less pleasant to use.
Portmaster offers 2 things that I find interesting: it uses filter lists like uBO does and can prohibit direct access to the Internet (programs that want to access the Internet without using the DNS).
