They aren’t, and our private phones are also connected to the network ;)
Why though‽ Most consumer routers even have a guest network enabled by default.
it really depends on what the company does.
That’s true, but an attack could probably cause a lot of damage to any company (especially a big one) without proper security. Regardless of what they do.
Well at least you don’t have to deal with ITs PC policies, which can get pretty annoying. Allowing any device to join the company network seems incredibly stupid though.
Let’s just hope that none of your unmanaged machines get compromised.
At my previous company, only domain work computers could join the PC WiFi (with a certificate, so no passwords) and work smartphones could only join the work WiFi for mobiles.
Private devices and very limited amount of non domain computers were only allowed on the guest network and couldn’t connect to any other.
The company didn’t do anything special that needed extra security.
