GOS Systems Improves Detection Technology

Major Upgrade to Tactical Intelligence Platform

London, 11 May 2015 - Touchstone (AIM: TGL), the AIM listed investment company, provides an update on GOS Systems ("GOS"), a UK security technology group recently acquired in accordance with Touchstone's investment policy.

GOS is pleased to announce major enhancements to its tactical intelligence platform, which is based on GOS's patented selective network diversion technology.

GOS's tactical intelligence platform enables real-time detection of cellular, voice and SMS, and its suite of products features bespoke hardware and software systems for mobile phone identity retrieval for target identification, locating and technical surveillance counter measure.

The enhancements have significantly improved the platform's capability to detect across multiple telephony networks in much shorter timeframes, and also allows for the implementation of new detection techniques. Several of the enhancements were facilitated through collaboration with major clients of GOS and the upgrade will be made available to existing and new clients immediately.

Franz Forrester, Touchstone COO commented "The advances reported today by GOS are the result of careful and assiduous planning by the team and represent another important milestone in the continuous development of GOS as a serious and credible player in the critical sector of homeland security. The past few months have proved the benefits to TGL of having acquired GOS from administration last year and investing both in the team and in capital investment in technology upgrades."
