ZyLAB is a developer of software for Information Access, e-Discovery, Email Management, Records, Contract,- and Document Management, Knowledge Management, and Workflow. The company is head quartered in McLean, Virginia and in Amsterdam, the Netherlands. ZyLAB’s most important products are ZyINDEX and ZyIMAGE.



In 1983 ZyLAB was the first company providing a full-text search program for electronic files stored in the file system of IBM Compatible PC’s. The program was called ZyINDEX. The first version of ZyINDEX was written in Pascal and worked on MS-DOS. Subsequent programs were written in C, C++ and C# and work on a variety of Microsoft operating systems.

In 1991, ZyLAB Integrated ZyINDEX with an Optical Character Recognition (OCR) program Calera Wordscan, which was a spin off from Raymond Kurzweil’s first OCR implementation. This integration was called ZyIMAGE. ZyIMAGE was the first PC program to include a fuzzy string search algorithm to overcome scanning and OCR errors.

In 1998, ZyLAB developed support to full-text search email, including attachments.

In 2000, ZyLAB embraced the new XML standard, and created a full content management and records management system based on the XML standard and build a full solution for e-discovery, historical archives, records management, document management, email archiving, contract management, and professional back-office solutions.

In 2003, ZyLAB invested in expanding the ZyIMAGE product suite with advanced Text analytics, Text mining, data visualization, computational linguistics, and automatic translation.

2005: ZyIMAGE Information Access Platform was released, an integrated solution to address Information Access problems.

2007: Platforms for ZyIMAGE e-Discovery and Legal Production, Historical Archiving, Compliance, Back-Office Records Management and COMINT were launched.


Initial customers of ZyINDEX were organizations such as the FBI and other law enforcement agencies to investigate electronic data from seized PC’s, The US-Navy for on-board manuals and various law firms around the world for e-discovery. Over the years, ZyLAB also received grants from the European Union (DG13).

Other well-known ZyLAB customers were: O.J. Simpsons Defense Team, various war crime tribunals around the world such as the Milosovic trial, the Special Court for Sierra Leone, the UN-AKRT-ECCC Cambodia Khmer Rouge trials and the Rwanda tribunal. In 2007, the EOP (Executive Office of the President) selected ZyIMAGE for email archiving, basically for its open XML structures, which is endorsed by organizations such as NARA. ZyLAB’s software was also used for many other high profile investigations such as the Oklahoma Bombing. See also the reference section.

Various public websites also use the ZyIMAGE software.

ZyLAB is a recognized leader in the development of 2007 Magic Quadrant for Information Access Solutions and received a Strong Positive Rating in the 2007 e-Discovery Marketscope and a Positive Rating in the 2007 and 2008 Records Management MarketScope.
