The article is kind of meaningless without comparing it to non-Apple devices in the same workplaces. Android devices are not exactly known for being locked down. I have been in organizations where Linux/Unix root passwords were both common knowledge and easy to guess. None of tehse have to do with the device.
For the enterprise, it would be nice if Apple could have separate identities, logins if you will, for work and personal on iOS. That problem is far from unique to Apple. Windows 10 on Surface may not have that problem, but it brings its own mature and broad set of malware as well.
Just not two weeks after Samsung's Knox Secure encryption devices were confirmed for top secret US Government devices, it was discovered that the passwords and keys for Samsung's encryptions and access to their phones and tablets that were supposedly Knox protected were kept in an easily found unencrypted TEXT file in a library on the phone itself. . . and later, their FINGERPRINT images were found in a similarly hidden, unencrypted file, that unlocked their supposedly secure phones!
They have NOTHING comparable to Apple's secure enclave which is located inside the processor and not accessible from outside the processor where one-way HASHes of passwords and fingerprint images are kept.
