If you use Microsoft's certificate services, you can configure an automatic
certificate enrollment group policy. This can generate certs for both users
and computers as needed. This works for Windows clients. If you have other
clients, you will want an MDM or alternatively a certificate onboarding
solution, though if you have Macs joined to Active Directory, you should be
able to issue the certs without a for-pay MDM.
