THE Package
Options Based on Customer's Need
Firewall Based on Complexity Requirements
In the majority of cases, the Ubiquiti will be the UTM of choice. Most small businesses will not have a complex enough Internet connection with self hosted, customer facing sites with the need for a reverse proxy. For those with that need, the OpnSense UTM will be used instead.
Server High Availability Based on Need and Server Budget
Having a high availability cluster is definitely a nice-to-have feature, however, that comes at a cost. There are different ways to ho high availability and also ways to do pseudo-high availability (Replication - not quite HA but close).
