Juno Pulse provides a single, consistent SSL VPN client that IT organizations could use across a range of different platforms. When used with Juniper's SSL VPN and unified access control (UAC) appliances, devices running the Juno Pulse client can also be handed off from VPN access to a direct connection, such as once a remote user arrives at their corporate campus.
From an endpoint security standpoint, Juno Pulse also provides network access control -- per the Trusted Computing Group's Trusted Network Connect standard -- when used in conjunction with Juniper's SA Series SSL VPN Appliances, WXC Series Application Acceleration Platforms, or UAC appliances. For the iPhone, Juno Pulse builds on new capabilities first announced by Apple in April. In a statement, Apple said that iOS4 -- the recently renamed iPhone 4 OS -- would support "forthcoming SSL VPN applications from Juniper Networks and Cisco."
According to Juniper's Brendan Lewis, iOS4 "will have integrated, world-class SSL VPN capabilities, versus just supporting IPSec VPNs." One advantage of using an SSL VPN, typically, is that it provides more fine-grained access control -- for example, role-based access to a subset of enterprise applications. Another advantage, historically, has been a lower cost of support, versus IPsec VPN clients.
