Did you know that Junos Pulse exists on every Windows 8.1 machine?
Each and every Windows 8.1 installation contains a variant of Junos Pulse called the "Junos Pulse In-Box VPN Plugin." The In-Box Plugin can be used to create VPN connections to certain Juniper VPN headends.
Microsoft occasionally releases Windows operating system updates that contain Pulse In-Box updates. The last such In-Box update was for the "Heartbleed" vulnerability on May 5, 2014.
