Sophos Endpoint Security and Control with NAC

Hello everyone,

i have an issue with some endpoints where NAC is installed. We run an weekly scan and check conformity of "Last Scan Grace Period". For some reason, there are a lot of endpoints which run this scan and have the value "{null}" but "0" is expected. So the endpoints with the wrong value are shown as "non-compliant". But they have to be compliant because they run the scan.

Are there any workarounds i can perform?

Thanks

Robby
