ETS has one of the most advanced digital forensic practices in the United States.

​These days, almost every case has a cell phone, tablet, or computer involved. We have the most advanced equipment and stay current on the latest tools, techniques, training, and certification to provide clients with best-in-class service nationwide.

Recovery of hidden and deleted data through logical and physical data extractions from smartphones and tablets including Phone, iPad, Android, Blackberry and Windows based devices can be done during depositions, in court, or at ETS' labs. Items that can commonly be recovered include passwords, emails, SMS text messages, chats, images, contacts, call history, website history, calendars, media files, geo-tags and location information, and documents. Information in cloud accounts can be extracted, as well, and imported into a separate forensic image and analyzed for comparison to data found on one or more devices.

On-site and in-lab imaging provides a bit-level copy of
all data from hard drives, memory chips, USB devices,
SD cards, GPS devices, CD's, and DVD's. The data
acquisition and imaging processes of a forensic evidence
evaluation are critical to the success of the case. Proper handling of digital evidence requires skilled hands and predetermined procedures to avoid damage to critical evidence and corruption of data. This includes documenting every step in the process and meticulously maintaining the chain of custody.

Expert witness testimony. We are experienced in depositions and live court appearances and have been accepted in Illinois courts as qualified to render an expert opinion in many subject areas.
