Corporate Profile

We have 27 years of experience stopping bad guys and finding bad guys.

GDF was founded in 1992. Initially, our focus was cyber security, and we became highly proficient at both preventing and mitigating damage done by cyber breaches and attacks. Computer forensics was a logical next step: If you're responding to a crime, why not also look for the criminals. And if you're going to catch criminals, then you've got to make things stick in court.

Simply put, we're different because we have almost three decades of experience helping clients deal with cyber crime at all phases - from protection to investigation to remediation, evidence presentation and prosecution. Our staff has real world experience in the field and in court, in addition to full training and certification.

Today, GDF discreetly assists many prominent companies with all aspects of cyber security, from breach response to threat assessments, penetration testing and threat remediation. We work with hundreds of law firms and attorneys on complex criminal and civil cases, providing investigation as well as expert witnessing. GDF is also on retainer as the leading forensic responder many private and public companies, including Fortune 100's.

GDF has worked with clients in many highly regulated industry sectors, including clients in finance and banking,  government agencies, defense industry manufacturers, healthcare and insurance companies, hospitals — organizations in all areas of business. Our staff provides expert, rapid response all over the United States, Europe and Asia.

I worked with Vince and the team at evestigate on a BitTorrent copyright infringement case. Despite encryption of drives, the team was able to provide me with the necessary information and confirmation needed to quickly resolve the dispute on favorable terms without the need for protracted litigation. I would highly recommend their services and have already made referrals to them.

I am writing to thank you for your office’s outstanding work in the above-captioned matter.  Despite not hearing from me until Friday afternoon, you were able to connect us to an expert who could do what we needed in time to get us a wonderfully-written report by Sunday afternoon.  What’s more, you and Mr. Caruso were flexible enough to work out a financial arrangement which provided my client everything he needed without additional expense.

I would also like to thank Mr. Knudsen for his excellent work on such short notice.  Within two days over the weekend, he was able to complete all the work that was required, as well as a very detailed report about his findings.  This report enabled Attorney Minnella to make a stipulation with the state prior to making his motion for judgment of acquittal; based largely on the stipulation, the Superior Court (Hon. Thomas O’Keefe) granted the motion for judgment of acquittal.  As a result an innocent man can finally rest easy knowing that he has been vindicated and no longer faces the threat of imprisonment for something that it is apparent he did not do.

Empowering our IT Department to work symbiotically with our Legal Team has saved us hundreds of thousands of dollars in fees and costs on a single matter. Frankly, we couldn’t have done it without the guidance and tools from GDF.

Electronic Discovery is more than creating TIFF Images of existing documents, it is necessary to identify less obvious sources of evidence, request it properly and make it usable, GDF's Electronic Document Discovery Services make the difference in the usability of data at pricing that keeps us within budget.
