Unlike McAfee ePolicy Orchestrator, SEPM does not have import or virus definition check-in feature that makes virus definition update easy. In an environment where internet is not available, you have to download the
.jdb file from symantec website, then copy the file to this path
C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\data\inbox\content\incoming this is the default path for SEPM. After you have copied the
.jdb file, SEPM will automatically process the definition update.
Step 3: SEPM will process the file, once the file is processed the .jdb file will be disappeared from
C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\data\inbox\content\incoming
