**MediaSentry** was a [United States](/source/United_States) company that provided services to the music recording, motion picture, television, and software industries for locating and identifying [IP addresses](/source/IP_address) that are engaged in the use of online networks to share material in a manner said organizations claim is in violation of [copyright](/source/Copyright). Their most notable customers were several trade associations including the [Motion Picture Association of America](/source/Motion_Picture_Association_of_America) and [International Federation of the Phonographic Industry](/source/IFPI).

The company provided several services for this purpose, such as monitoring popular forums for [copyright infringement](/source/Copyright_infringement), aid in litigation, early leak detection, and the distribution of decoy files.[1] MediaSentry also monitored auction sites such as [eBay](/source/EBay) for unauthorized distribution of software and other property.

## History

On 1 February 2001 MediaSentry was founded by Aaron Fessler in [Morristown, New Jersey](/source/Morris_County,_New_Jersey).

On 13 June 2005 MediaSentry was acquired by [SafeNet](/source/SafeNet).[2] SafeNet sold the MediaSentry division to [Artistdirect](/source/Artistdirect) in April 2009.[3]

In late 2007 the [University of Oregon](/source/University_of_Oregon), represented by [Oregon Attorney General](/source/Oregon_Attorney_General) [Hardy Myers](/source/Hardy_Myers), refused to provide information on its students to the [RIAA](/source/RIAA), questioning the tactics used by MediaSentry in one of its investigations.[4] The next year [Central Michigan University](/source/Central_Michigan_University) accused MediaSentry of violating its students' privacy[5] after the company ignored a ruling that it was illegally operating without a private investigator's license.[6]

In January 2009 the RIAA canceled their usage of MediaSentry for undisclosed reasons.[7]

In August 2009, [ARTISTdirect](/source/ARTISTdirect) restructured [MediaDefender](/source/MediaDefender) and MediaSentry, creating [Peer Media Technologies](/source/Peer_Media_Technologies).
