I was at a subsidiary of a very large company and had work slack, email, and all my code on my phone, without even the thing that lets them remote wipe your phone.
It has to do with culture and willingness to put in the effort by the security organization
Not exclusive to IT; I had to weigh the benefits of continuing to work as a caregiver for a small company, versus working in retail for a massive chain (which translates to fantastic insurance benefits.)
Fuck their data, what about my own? That pest of an app is not getting onto my device. And neither is anything else that gives an employer any control over my device.
For clarity, the android feature essentially makes a work dedicated partition on the phone. Their management app can manage that partition, and for the purposes of data movement it's essentially a distinct phone.
If they've set it up correctly they can do a remote wipe without touching your personal data.
In a lot of cases the drive to have users use their personal devices rather than employer owned ones comes from the users, not the workplace. Only needing to keep track of one device is easier in many cases.
Eh, it doesn't need to be, you just need to do the work of putting together granular access controls that can account for your risk profiles.
The risk isn't much different between a company owned telephone and a personal telephone.
They're both susceptible to most of the same attacks, or being left on the bus.
In my current job the old manager okayed working on our own devices.
I would use my personal workstation to ssh into and do work on my work mac, did that for a few years. saved me disassembling my desk between uses every day or buying a costly KVM.
They seem to be getting a lot more uptight about security these days (although the "you can work on personal devices" rule hasnt been explicitly rescinded) so i have stopped interaction between my personal devices and work devices.
Having a M2 mac recently makes it easier, i can lie in bed and work pretty much all day on a single charge so my desk remains intact
