Re: O M G
I used a lot of DrayTek routers early in my I.T. career, and they were unbeatable on price, features and support. But they're also quite ... eccentric. After having exposure to mainstream enterprise products (Palo Alto, Fortinet, Juniper, Cisco, etc.), I felt pretty "cramped" going back to working on DrayTeks.
In recent years, Netgate has replaced DrayTek as my weapon of choice in the SME or SOHO space - particularly the pfSense-based routers. They tend not to come with built-in modems or Wi-Fi, but on other features (firewall, NAT, logging & monitoring, DNS resolver, etc.), they blow equivalent DrayTeks out of the water. You can add packages as you require (e.g. Snort, Wireguard, haproxy, Squid, etc.). And the devices normally receive updates for a long time. I have an SG-1100 at home, which was released in 2019, and there's no sign yet of Netgate announcing an EOL. Still regularly updated. (For SME I use larger appliances - 2100 and 4200.)
Yes, you can run pfSense on lots of other hardware, but for an SME, it makes sense to go with a supported device. The main drawback is that their "Multi-Instance Management" implementation is still very early stage. If you're managing a fleet of routers, maybe try Sophos XG. Not as strong a value proposition as Netgate, but more mainstream, while being (IMHO) more accessible than any of the Gartner leaders.
