at a company I used to work at, yes, very much so. our personal devices were checked into a locker with security before entering the secured part of the building. you were free to come back out to use it when you needed during the day. the USB ports to our workstations were covered with epoxy. the desktops didn't actually connect to the internet, so email/etc used a remote citrix connection to isolate networks. any network transfer over a set size would send notices. to be honest, it was glorious to be without the device. the shit part was everyday when leaving the office you had to have your bags searched.
