Hamachi VPN

Hamachi VPN

What it is
With Hamachi you can organize two or more computers with an Internet
connection into their own virtual network for direct secure communication.
Hamachi is fast, secure and simple. It is also free.
What’s in it for me
Think – LAN over the Internet.
Think – Zero-configuration VPN.
Think – Secure peer-to-peer.
Access computers remotely. Use Windows File Sharing. Play LAN games. Run
private Web or FTP servers. Communicate directly. Stay connected.
Technology
Hamachi is a zero-configuration virtual private networking application with
an open security architecture and NAT-to-NAT traversal capabilities.
Hamachi is the first application to mix seemingly unrelated networking
technologies in one powerful package to deliver an unprecedented level of
peer-to-peer connectivity. More …
Security
Hamachi is secure. All Hamachi communications are encrypted and
authenticated with industry-standard algorithms and protocols. Nobody will
be able to see what two Hamachi peers are talking about. Not even us.
However what is equally important – Hamachi security architecture is
completely open meaning that its detailed description is available for the
review to anyone interested. More …
Ease of Use
A special effort went into designing and polishing Hamachi user interface.
The result is sleek, simple and intuitive, while still very much functional.
Everything you need, nothing you don’t.
Hamachi software contains no spyware, bannerware or any other -ware
unrelated to its purpose. And it never will.
