Wow, I feel morally compelling to comment on your comments. Stop telling false information to people in unknown. "VPN is a very old tech and is becoming harder and harder to maintain and constantly needs patching to keep it viable and It is slow. VPN is near the end of its life and will be phased out over the next 10 years." - what a load of bullshit! VPN is a type of secure virutal network, which has been existing for many years and will continue to exist and evolve. And how bold you claimed "VSN is next generation of VPN"! If you don't understand technologies, please stay quiet, don't come out to mislead people and embarrass yourself.
I encourage anyone confused refers justinr's above comment to your trusted IT professionals for opinions. It's ridiculous and immoral to put out such false information.
By my guess, this so called VSN is likely some encryption component, either in the form of hardware or software module, to facilitate securely transfer information over internet, more like SSL/TLS and is not an equivelent to VPN. If this is the case, it's basically worthless as tons of commercial and free libraries already available, and they are evolving quickly (remember VSN has its patent in 2013, what an antique tech!). Basically most of contemporary software has such built-in function as basic security. For example, when you use whatsapp, Skype etc, you got peer to peer encryption, which is nothing more than encrypting the messages between the session peers, and no middle man (server) knows the key to decrypt your messages.
VPN, on top of this message encryption function, also establishes a virtual network infrastructure for you, making your device as if connected to the destination network so that you can access your office internal network drives etc.
And I would challenge the company's claim on high performance and low latency - network latency is accumulation of delay of all traffic nodes, VIN at most improves the client side encryption time, if they really do faster encryption work. Generally speaking, network performance are dictated by the pipe between the ends. In today's terminal hardware performance, even the slowest encryption library probably contributes 0.01% of the total latency of a connection.
I feel sorry for you guys got excited on seeing the above justinr's comments. It's just NOT TRUE!
