It allows the investigator to conduct in-depth analysis of user files to collect evidence such as documents, pictures, internet history and Windows Registry information. The company also offers EnCase training and certification.
Data recovered by EnCase has been used in various court systems, such as in the cases of the BTK Killer and the murder of Danielle van Dam. Additional EnCase forensic work was documented in other cases such as the evidence provided for the Casey Anthony, Unabomber, and Mucko cases.
