Question regarding random Decryption when using Cortex XDR

L0 Member

Hello all,

Wanted to ask if any of you had something similar happening around.

Scenario : 

2 systems (just as an example, as they are more) - 1 of the systems gets decrypted after a system update was done (BIOS, driver updates etc.) , the other system does not get decrypted for the same updates, instead the BitLocker suspends itself and after the upgrade is done, it 'resumes' itself (which in my opinion is the correct expectation). This information I get from Event Viewer (sadly I can't see what the decryption issue is there, neither can I see it in the traps logs).

Both of the systems are using the same encryption profile from Cortex, both of the systems are using the same GPO configuration that pushes Cortex BitLocker encryption.

At first I though it might be related to no AD connectivity prior to the upgrade initiation, but this was false, I checked if Secure boot might cause it, but this was also false. Both of the systems are using UEFI.

Anybody got any idea what specs/configs I need to check/compare for those systems that decrypt and those that do not?

Thank you!
