Is Vedivi a VPN software (Virtual Private Network) ?

Yes.

It is much more than a VPN and it offers all the features of the most advanced classical VPN for a single user or small groups of users
It also contains added benefits:

• No Server or Hardware required: Unlike classic VPN, Vediviis purely Software based, and only requires a software on both end (pretty much like a messenging tool (skype, MSN or Yahoo messenger...).This offers great flexibility and allows end-user or small companies to use it with no IT help.
• Bi-directional:You are not limited to connecting from Home to your Office, you can also connect from your Office to Home, Vedivi is fully bi-directional and allows connectivity if both direction (Office->Home, Home->Office...).
• Performance & reliability: Classic VPNs normally require dedicated lines or offer poor performances over internet connections (limited bandwidth, frequent disconnections).Vedivi has overcome all these problems (proxy hashing, tcp meltdown...) and offers a highly performant (we have tested Vedivi with > 30Mbs transfer) and reliable (TCP connection stay connected when an internet connection is momentarily lost).
