ProductsZyLAB Information Management Platform and various bundles for eDiscovery, email & SharePoint archiving, text-analytics, visualization, contract management, and workflow.

ZyLAB is a developer of software for e-discovery, information risk management, email management, records, contract, and document management, knowledge management, and workflow. The company is headquartered in McLean, Virginia and in Amsterdam, Netherlands. ZyLAB’s most important products are ZyLAB eDiscovery & Production System, the ZyLAB Information Management Platform and bundles that build systems for deployments.


In 1983 ZyLAB was the first company providing a full-text search program for electronic files stored in the file system of IBM-compatible PCs. 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, the company 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, the company 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.

Platforms for ZyIMAGE e-Discovery and legal production, historical archiving, compliance, back-office records management and COMINT were launched in 2007.

2010: ZyLAB Information Management Platform was released, an integrated solution to address e-Discovery and information management problems.


Initial customers of ZyINDEX were organizations such as the FBI and other law enforcement agencies to investigate electronic data from seized PCs, the U.S. Navy for on-board manuals, and law firms around the world for e-Discovery. Over the years, ZyLAB received grants from the European Union (DG13).

Other well-known ZyLAB customers were O.J. Simpson's defense team, war crime tribunals such as the trial of Slobodan Milošević, the Special Court for Sierra Leone, the UN-AKRT-ECCC Cambodia Khmer Rouge trials and the Rwanda tribunal. In 2007, the U.S. Executive Office of the President selected ZyLAB for email archiving, basically for its open XML structures, which is endorsed by organizations such as the National Archives and Records Administration. ZyLAB’s software was used for many other high-profile investigations such as the Oklahoma City bombing.

Public websites also use the ZyLAB Webserver.

Gartner positioned ZyLAB in the "Leaders" quadrant in its 2007, 2008 and 2009 Magic Quadrant for Information Access Solutions, gave it a strong positive rating in its 2007, 2008 and 2009 e-Discovery Marketscope and a Positive Rating in its 2007 and 2008 Records Management MarketScope.

ZyLAB’s chief strategy officer, Dr. Johannes C. Scholtes, is professor in text mining at the University of Maastricht faculty of Humanities and Sciences and director in the board of AIIM.
