Founded in 1987 and located near Boston, Massachusettss, Granite Island Group, is THE internationally recognized leader in the field of Technical Surveillance Counter Measures (TSCM), Bug Sweeps, Wiretap Detection, Surveillance Technology, Communications Security (COMSEC), Counter-Intelligence, Technical Security, and Spy Hunting.
Granite Island Group provides expert technical, analytical and research capability for the detection, nullification, and isolation of eavesdropping devices, technical surveillance penetrations, technical surveillance hazards, and physical security weaknesses... Simply put, we hunt spies, stop espionage, and plug leaks.
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, Signals Analysis, TEMPEST, 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, wiretap detection, 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. At the time there was only one company in the entire country who could do this... and we were it.
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.
Granite Island Group has had an Internet presence since 1987, and James Atkinson has been active on the Internet since the mid 1970's. With the growth on the Internet in the early 1990's came an FTP/UUCP library, then an IRC reflector, and a dedicated E-Mail based list for discussion and to publish and exchange files related to TSCM and ongoing projects. With the advent of "Mosaic browsers" several years later the informational files and documents were converted to HTTP (or Hypertext Documents) and placed on a dedicated domain in 1994 (www.tscm.com)
The web site developed to over 1,950 publicly assessable documents related to TSCM, technical counter-intelligence and technical security which involves well over 78,200 printed pages. The site currently handles an average of over 4,500 visitors a day from all over the world. It is the first, the largest, and most complete site anywhere on the Internet dedicated to TSCM, Technical Counter-Intelligence, and Technical Security.
Warning Signs That You Have Been Bugged
O divine art of subtlety and secrecy!
Through you we learn to be invisible, through you inaudible;
and hence hold the enemy's fate in our hands.
TSCM 101 - The Technical "Meat and Potatoes"
The following are a series of brief entry level tutorials regarding
specific areas and topics relative to TSCM and methods used to find
bugs and other eavesdropping devices.
No enterprise is more likely to succeed than one concealed
from the enemy until it is ripe for execution.
We are apt to shut our eyes against a painful truth...
For my part, I am willing to know the whole truth; to know the worst;
and to provide for it. -- Patrick Henry
you free." - John 8:32 KJV
