Depends on on how you define company, banks won’t use them, small businesses will.
If Synology use’s LUKS encryption, how can it be cracked without the key ?
Usually these devices have a kensignton lock, obviously they can pull out the drives.
Must admit I use a QNAP, believing even if someone would steal the unit or the disks they would not be able to access the data, after a power cycle, the disks need to be decrypted (8 times in my case with 8 different keys for 8 bays).
Most of these NAS’s (especially QNAP) are attacked online, I think almost no one cares about the data except the owner, LOL can’t imagine anyone wanting to steal my 20 years of accumulated project management knowledge and work, though if I lost it I would not be able to replace it.
