# EnCase

EnCase is the shared technology within a suite of digital investigations products by Guidance Software (acquired by OpenText in 2017). The software comes in several products designed for forensic, cyber security, security analytics, and e-discovery use. EnCase is traditionally used in forensics to recover evidence from seized hard drives. 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 (Wakefield Massacre) cases.

## Company and Product Overview

Guidance Software, and the Encase forensic tool, was originally created by Shawn H. McCreight.
In 2002 EnCase Enterprise was released allowing the first network enabled digital forensic tool to be used in forensic, investigative, and security matters.
In 2005 EnCase eDiscovery was released which further enabled the network abilities of EnCase to allow Identification, Collection, Preservation, and Analysis of ESI for Litigation and Investigative purposes.
In 2007 EnCase AIRS (Automated Incident Response Suite) was released (now discontinued and evolved to EnCase Endpoint Security) to automate the scanning, documenting, and remediation abilities of EnCase Enterprise. In 2007, EnCase Information Assurance, EnCase Data Audit and Policy Enforcement (both also effectively integrated into EnCase Endpoint Security) were also released.
In 2008 EnCase Cybersecurity was released which combined many of the tools and automation from previous security functions and streamlined the workflow of incident response.
In 2015 EnCase Endpoint Security was released which was the evolution of Endpoint Security into a more user-friendly web interface as well as further integration with many other security tools to further expedite and shorten the response time from an attack or event.
In 2016 EnCase Enterprise needed a face lift and the distributed agent (formerly referred to as servlet) was given more abilities with the redesign into EnCase Endpoint Investigator. Also in 2016 the release of EnCase Risk Manager for data risk assessment, audit, DLP-like services, and compliance.
In 2017 Guidance Software was acquired by OpenText, and the company name "Guidance Software" is no longer used.

## Features

### Expert Witness File Format

EnCase contains functionality to create forensic images of suspect media. Images are stored in proprietary Expert Witness File format; the compressible file format is prefixed with case data information and consists of a bit-by-bit (i.e. exact) copy of the media inter-spaced with CRC hashes for every 64 sectors of data (by default). The file format also appends an MD5 hash of the entire drive as a footer. The E01 file format was reversed engineered and specifications can be found here.

### Mobile forensics

As of EnCase V7, Mobile Phone Analysis is possible with the addition some add-ons available from Guidance Software.
