Hello , 

Yes 14.3 should be supported.  Netskope announces support at the major release level.  For Sonoma, ensure that your clients are at least version 109.  Additionally, keep in mind Sonoma also has an additional requirement for approving full disk access.   Granting this access is documented but it depends on your MDM.  For example, JAMF instructions are documented here. 

I onboarded before Sonoma and recently discovered this revised guidance for Sonoma. We do not currently have the Full Disk Access granted for ‘com.netskope.client.Netskope-Client.NetskopeClientMacAppProxy’ in our PPPC payload from Jamf MDM. We are not using Endpoint DLP, just the traffic steering component. Is there any more info on the implications of not having this granted in our case? So far I don’t see anything wrong, so I am reluctant to push out a PPPC change without more info or some idea of what isn’t working because of it.

Yes it is a supported version!
