DLP issue driver not installed - Hdlpdbk - removable storage blocking feature does not work

Hello I am running epo 5.9.1, agent 5.6.3, DLP11.4, ENS10.6, and DLP used to work well in past, after around 20 November I encountered DLP is no longer working well in means of blocking non-corporate USB flash drives - removable storage.

when I run diag tool I see possible cause - no blocking driver installed - could it be the issue (?)
I think other causes might be:
some certificate on driver or agent or epo level (?)
ENS exception for processes fcag*.exe missing (?)



Generally the DLP plugin is show in agent-tray-menu, GUI shows policy present, but upon plug of USB drive, no action is taken (block/report/info for user).

If there is more need for evidence or symptomps, or comment on what I tried, please let me know. Thanks for any advices or support.

Re: DLP issue driver not installed - Hdlpdbk - removable storage blocking feature does not work

@tbloudek Thank you for choosing McAfee Support Community.

HDLPDBK driver used in DLP to block device at Driver Level which is loaded when you use Plug and Play (PnP) Rule. From your description, I can understand you are using Removable storage rule to block USB which uses HDLPFLT which is already loaded in your machine.

I believe the device you are using may be detecting under PnP Device Type so it is allowed. Since the endpoint status for Device blocking is "No" i believe you have not configured PnP rule or the policy enforcement is not successful at the endpoint.

Please check the device detection type in HDIAG Tool and configure the rule accordingly to block it.
