Hi,
Indeed R80 does not contain the latest version of Endpoint Security Management (aka R77.30.01 / E80.62 HFA1). Alignment of both products is planned for the next releases.
For now, the only solution to support both will be having an R80 Management server and a separate R77.30.01 Management server just for the Endpoint Security policy.
By the way, an EA program of Endpoint R77.30.02 / E80.64, which includes improvements in the Endpoint blades, as well as SandBlast Agent, is currently happening. If you are interested, please contact your SE.
