It is worth remember that unlike those home routers, Ubiquiti's EdgeOS is based on a production major network os, Vyatta, (as is VyOs), and therefor has a lot more scrutiny and bug fixing than those other things, which are often even more complicated by the lack of foss hardware or standardized ways to do things (many routers are stuck on whatever the manufacturer put on it in the factory). I'm sure Ubiquiti's code is probably ripe for fuzzing, etc, but a well configured EdgeOS device I would put against any cisco, cumulus , extremeos, routeros, junos, pfsense, ipfire, etc device any day. The main benefit of something like Ubiquiti being asic offload that wouldn't exist if you did something like pfsense on cots x86.

The real irony of how vulnerable these devices are, is that often they are based on tech that is foss that has updates to fix those issues but has been carefully packaged up inside a blackbox the consumer doesn't get to control and therefor doesnt get those updates.

Once again, why we need a "right to root".

For national security!
