LogMeIn Hamachi is a VPN service that easily sets up in 10 minutes, and enables secure remote access to your business network, anywhere there's an Internet connection.
It works with your existing firewall, and requires no additional configuration. Hamachi is the first networking application to deliver an unprecedented level of direct peer-to-peer connectivity. It is simple, secure, and cost-effective.
The preview release of LogMeIn Hamachi Mobile is a secure VPN client for the Windows Mobile platform, offering connectivity from dispersed environments to your enterprise resources. It operates and behaves much the same as the existing Hamachi for Windows, with some features removed or modified to adapt to the Mobile OS.
