It is possible to update the AntiVirus definitions on a Symantec Endpoint Protection Manager (SEPM) or Symantec Endpoint Protection (SEP) client using a downloaded .JDB file. AntiVirus definitions on SEP clients may also be updated via an Intelligent Updater (IU).
Is there a similar, standalone method for updating SEP's other protection technologies such as Intrusion Prevention System (IPS), Network Threat Protection (NTP) or Proactive Threat Protection (PTP)?
For releases prior to SEP 12.1 RU3, only AntiVirus definitions can be updated by downloading a standalone file such as a .JDB file or an IU. All other content types must be downloaded using LiveUpdate.
For SEP 12.1 RU3 and above, .jdb and .exe standalone updaters are available for SONAR ("Behavior-Based Protection") and IPS ("Network-Based Protection") definitions. These are now available from Security Response's Virus Definitions & Security Updates page.
Please note: these SONAR and IPS updaters are only designed to function with SEP 12.1 RU3 and above. For more information, please see Latest Symantec Endpoint Protection Released - SEP 12.1.RU3
