Pulse Secure *is* something that is run by enterprises as "their own." It is either a physical appliance or a virtual appliance that you run on your own infrastructure. No different in concept that any other "do it yourself" VPN, other than you actually have enterprise-level support.
This vulnerability is horrible, but it is not like any other piece of software would inherently be better, be it proprietary, open source, or whatever.
