We are in testing with the DLP agent and one of the first things I noticed is that transferring an MDB/ACCDB file causes a huge delay. Really, that's no surprise because the agent is supposed to scan the contents of the file.
What is surprising is that in my test policies I have exclusion of MS Access database files over 100MB. Despite this exclusion, I am seeing a 1min :45sec delay (sitting at 0%) before even starting the file transfer. The file is ~845MB and it's an MDB, so this should match the exclusion.
I even disabled *all* policies on the endpoint servers. No change. The only way I could get it to go away was by shutting down the agent.
Does anyone have experience successfully excluding MS Access files?
