Trident Media Guard (TMG) is a French company that specializes in software to prevent unauthorized copying of files over the Internet. Founded in 2002 by Alain Guislain and Bastien Casalta, it is located in Saint-Sébastien-sur-Loire near Nantes.

It aims to "provide services to major publishing companies of the recording and film industry to stop the loss of revenue due to illegal downloads on peer-to-peer networks."

It was selected in late January 2010, by the music and film industry to address copyright infringements on the Internet as part of the HADOPI law. In this context, it will aim to identify the IP addresses of users making illegal downloading, and then send that information to HADOPI.[1]

Trident Media Guard and Thierry Lhermitte jointly received the Special Mention prize Orwell Internet at Big Brother Awards 2010.[2]
