Our Story

I am David Gallant, President, GCIS. I have over 29 years of investigative experience, including over 22 years dedicated primarily to computer related crimes.  While serving as a Federal Agent in the US Air Force with the Air Force Office of Special Investigations (AFOSI), I was the case agent on numerous significant investigations involving sensitive Air Force assets, and coordinated the initial investigative activity for one of the most successful, multi-agency international computer hacker investigations in history.  I retired from the Air Force in 2001 with multiple honors.

Following my retirement, I entered the corporate security world with a startup company and helped build it into an internationally recognized leader in computer forensics, incident response, and incident response training. I was a key contributor to the success of Helix(™), a leading open source incident response software suite.  I have trained hundreds of federal, state and local law enforcement officials, as well as IT security personnel in the proper methodology for securing and analyzing computer evidence.  I am frequently sought to speak to attorneys and IT security audiences, and have authored several articles related to computer forensics, Internet safety, and computer security.

I am also a part-time contract instructor for AccessData Corp - continuing my desire to train law enforcement and IT security personnel in proper evidence seizure and forensic analysis techniques.
