NX security is guaranteed at every layer involved in the communication process. NX uses SSH public-key encryption and 128 bit volatile random cookie generation.

NX transparently tunnels Linux multimedia channels. Not only does NX play KDE and Gnome system sounds, but you can listen to MP3s played on the server and local workstation simultaneously.

Thanks to its outstanding compression performances, NX is able to deliver X, RDP and RFB remote sessions using the same client. This is achieved by translating "foreign" protocols into X-Window, the native protocol of NX.

Behind NoMachine software is the NX Distributed Computing Architecture, a suite of Open Source technologies and commercial tools, designed by NoMachine to make network computing as easy and widespread as Web browsing. NoMachine has built the foundations of its NXDCA on two well known and widely used open standards, SSH and the X-Window System, the windowing system which is behind the Graphical User Interfaces of Linux and the Unix Operating System.
