Granite Island Group Profile and History
Granite Island Group was initially formed to provide TSCM and SIGINT training services to the Army Intelligence School located at Fort Devens, MA. Engineering, design, and related services were also provided to various research facilities and defense contractors throughout New England. These services also included product design, fully instrumented TSCM surveys, bug sweeps, wiretap detection, SCIF compliance inspections, shielding evaluations, and other engineering services related to the technical security and protection of classified information.
Design projects included the development of several briefcase and man-pack systems used for signals exploitation and surveillance, along with suites of software products used to control test instruments for automated ECM, SIGINT, TSCM and related measurements.
In 1989 the services offered were expanded to include the design, installation, and maintenance of high performance computer networks used in secure facilities. This included performing TSCM and bug sweep services on desktop computers, data networks, and PBX/ESS systems to identify weaknesses which could allow technical penetrations or the compromise of classified or sensitive information.
Granite Island Group currently provides TSCM, bug sweeps, wiretap detection, and communications engineering services to a wide range of clients and has become one of the most respected names in the industry.
The web site developed to over 1,800 publicly assessable documents related to TSCM, technical counter-intelligence and technical security which involves well over 75,000 printed pages. The site currently handles an average of over 4,500 visitors a day from all over the world.
