Hey /u/JohnITAdmin,
Have you taken a look at our Sophos XG Firewall? It's also able to be deployed on Azure.
I'll send you a PM to follow up.
Cheers,
Your cheapest option isn't even an option for the majority of people on this sub.
Snort is ONLY an IDS, and the CHEAPEST business option is $399 a year. Personal is not licensed for business use, the the free one IS THIRTY DAYS BEHIND in definitions.
Here is everything that Sophos offers over just a consumer grade firewall. https://www.sophos.com/en-us/products/next-gen-firewall.aspx
