Since its establishment in 1990, the company has been working on computer security programs, with the main focus on password and system recovery software.

On July 16, 2001, Dmitry Sklyarov, a Russian citizen employed by ElcomSoft who was at the time visiting the United States for DEF CON, was arrested and charged for violating the United States DMCA law by writing ElcomSoft's Advanced eBook Processor software.

The technology first appeared in 2007 and employs the time–memory tradeoff method to build pre-computed hash tables, which open the corresponding files in a matter of seconds instead of days.

On November 30, 2010, Elcomsoft announced that the encryption system used by Canon cameras to ensure that pictures and Exif metadata have not been altered was flawed and cannot be fixed.
