OpenText also acquired Guidance Software a few years ago. They make EnCase which is one of the largest digital forensic software tools utilized for investigations.
I was a developer at Guidance from 2003-2010. I left because the future was easy enough to foresee. There might be one or two developers left at OpenText whom I know, but most have left. It’s all about milking that Enterprise SMS revenue.
X-Ways and Magnet are rightfully decimating EnCase’s traditional use in forensics.
