For extra security, you can add a firmware password to Macs, especially since Find My Mac is essentially useless (unlike for iPads, which have an activation lock preventing thieves from reactivating the iPad after a factory reset) and DEP-to-MDM enrollments for Macs can even be avoided by thieves if they're resourceful enough.
If you have a laptop with a firmware password, you need that password to boot from anything except the startup disk. Combine that with FileVault encryption, and a stolen Mac is pretty much useless. Doesn't mean that you'll necessarily get it back, but the likelihood is higher if the device is useless to thieves.
You can, of course, enable the firmware password via Recovery Mode, but it's easier to do it from the command line:
There are two modes for a firmware password: command and full. By default, the firmware password mode will be command, which means you'll be prompted for the password only if you boot from something other than the startup disk. If, for some strange reason, you want the mode to be full, it would mean you'd be prompted for a firmware password at every boot, regardless of what you're booting to.
A few other commands you might find useful...
If you want to script firmware password setting, someone wrote a fairly simple script that does it. There's also firmware password manager, which is a far more sophisticated way to manage firmware passwords.
Nota Bene: If you enable a firmware password, you can get into target disk mode by holding down the Alt/Option key at boot, typing in the firmware password, and then holding down the T key. However, you will be unable to boot into Safe Mode unless you delete the firmware password.
