NoMachine is remote desktop software built on the NX protocol, which the vendor says delivers high performance. Users work on another computer as if sitting in front of it. Functions include file sharing, printing, two-factor authentication, SSH tunnelling, browser-based access and screen recording. The range covers Personal and Enterprise Desktop editions, mobile clients, and Terminal Server and Cloud Server products. NoMachine Network is an optional subscription service that lets machines be reached behind firewalls.
NoMachine S.à r.l. is based in Luxembourg, so EU law applies to the vendor. The enterprise products are self-hosted, so the customer controls where data, desktops and applications are kept. The software is proprietary and commercial: the core NX compression code was released under the GPL in 2003, but NoMachine 4 made NX closed source in 2013. The pages consulted do not state where NoMachine Network runs, so this should be confirmed if it is used.
