JOHN BRADLEY, Master Instructor
John Bradley is the CEO, Founder, Principal Investigator and Chief Software
Architect at SiQuest.
He is a former police Sergeant and 17 year veteran of the Durham Regional Police Service, the largest regional police service in Ontario. John first became involved with computer forensics in 1997 while still assigned to uniform patrol. He was frequently seconded to the Major Crime Branch, on a per case basis, to manage all computer technology aspects of select high profile criminal investigations.
In the years that followed, John became involved in several major criminal investigations involving homicide, serious sexual assault, and crimes against children (eg: child pornography). His computer forensic discoveries and presentation of the evidence in court were pivotal to the conviction process, in almost each case. In recognition of his efforts, he was awarded a commendation of distinction by the Crown Attorney, citing his particular expertise in Durham’s first homicide by poison in May of 2000.
A true innovator and self-taught programmer, John began developing commercial software in 1993 while still assigned to uniform patrol. His earlier projects were geared mainly towards the automation of criminal court documents. However, he soon became focused entirely on computer forensic tools development with an emphasis on creating time-saving solutions to help with his own investigations. With the interest of making his tools available to law enforcement worldwide, John created Armor Data Inc. as a part-time software development company in order to manage the distribution of his software.
In April 2006, John left policing and joined Canada’s Scotiabank as the Director of Technology Crime and Forensics. He was responsible for all electronic investigations, both domestic and abroad and building the bank’s forensic infrasture. Tired of the mundane day to day board room meetings, John ventured out to start his own professional services and computer forensic software development company. In doing so, Armor Data Inc. was officially renamed to Digital Investigations Group Inc.
Since 2006, John has evolved as a business leader, a seasoned computer forensic investigator, and as a professional software developer. His biggest achievement to date has been the development of “CacheBack”, a sophisticated Internet cache and history analyis tool now in its second generation. CacheBack® has quickly become the tool of choice for most Internet related investigations with international users from all major levels of governement and law enforcement. The positive feedback about CacheBack, and his company’s dedication to supporting law enforcement, have once again given rise to the need for corporate re-branding.
Not complacent by his accomplishments, John is extremely focused on innovation and is determined to continually engineer new products for the forensic industry. That is why in October 2009, he re-established the company as “SiQuest Corporation”.
“With a name like SiQuest, people will come to know us as innovators and pioneers of Internet forensic software. SiQuest will introduce a whole new calibre and genre of forensic products and we will listen to our users and respond to their needs. There has never been a greater time to be involved in computer forensics and we are looking forward to making a difference.”
