Notable case mentions

Guidance Software has been noted in a number of high-profile use cases. In 2002, Guidance Software's EnCase was used in the murder trial of David Westerfield to examine his computers and disks to connect him to child pornography. That same year, EnCase was used by French police to uncover emails from now-convicted shoe bomber Richard Colvin Reid.[http://www.govtech.com/security/EnCase-helps-finger-murder-suspect.html Government Technology], retrieved 03 June 2011

In 2004, EnCase software was used in the trial of now convicted Scott Peterson for the murder of his wife, Laci Peterson. Computer forensic experts used EnCase to examine Peterson's five computer hard drives, which provided valuable evidence that he had shopped online for a boat, studied water currents, bought a gift for his mistress in the weeks leading up to his wife's death and showed interest in a computer map that included Brooks Island, where his wife was later found.[http://www.cf-intl.com/labj_092704.htm Los Angeles Business Journal] {{Webarchive|url=https://web.archive.org/web/20080514095906/http://www.cf-intl.com/labj_092704.htm |date=2008-05-14 }}, retrieved 03 June 2011

In 2005, American serial killer Dennis Lynn Rader (also known as the BTK killer) sent a floppy disk to FOX affiliate KSAS-TV in Wichita, Kansas. Using EnCase, police were able to find metadata embedded in a deleted Microsoft Word document that was, unbeknownst to Rader, on the disk. The metadata contained "Christ Lutheran Church", and the document was marked as last modified by "Dennis." A search of the church website turned up Dennis Rader as president of the congregation council. Police began surveillance of Rader.

In 2011, following Sony Online Entertainment's multiple security breaches, Sony said it would be working with Data Forté, Guidance Software and Protiviti to resolve its PlayStation breach.[https://techland.time.com/2011/05/04/whos-cleaning-up-the-psn-debacle-for-sony/ TIME], retrieved 03 June 2011 And in May 2011, after the killing of Osama bin Laden, it was reported that an assault team of Navy SEALs removed computers, hard drives, USB sticks and DVDs from bin Laden's compound for forensic analysis. Based on a job description supporting the task, Guidance Software's EnCase is believed to be the tool selected for analysis of the electronic gear.[https://web.archive.org/web/20110507085935/http://www.cbsnews.com/8301-501465_162-20060347-501465.html CBS News], retrieved 03 June 2011 Later that year, Guidance Software's EnCase was noted as a forensic software tool used in the trial of Casey Anthony, following the death of her daughter Caylee Anthony.[http://www.wftv.com/video/28170916/index.html WFTV 9] {{Webarchive|url=https://web.archive.org/web/20110712015558/http://www.wftv.com/video/28170916/index.html |date=2011-07-12 }}, retrieved 30 June 2011 Investigators used EnCase to search digital cameras and computers.
