I just mentioned basic security check but I don't know anything about corporate networks or how to manage them. One thing I know is that Microsoft has robust network directory service called Active Directory which "authenticates and authorizes all users and computers in a Windows domain type network—assigning and enforcing security policies for all computers and installing or updating software." So for example you could register all corporate access points to a Windows domain and no way you get connected to a wrong access point.
The article does make the same point. Basically companies could configure their WiFi in a more secure fashion but many won't. I'm certain many small companies use very basic setups similar to a home WiFi and at best will just change the WiFi password periodically.
This is why major OS providers are taking it on themselves to tackle some of these issues independently of the WiFi setup - like taking the location in consideration and warning you if you connect to the same network in a different location.
