Zantaz buys Singlecast's data classification and policy management tools Zantaz, a maker of storage archiving technology, is acquiring Singlecast Technologies for its data classification and policy management tools.Zantaz, in Pleasanton, California, is acquiring the technology assets of Singlecast, based in New York City and Atlanta, and will retain most of the company’s employees. The terms of the acquisition were not disclosed.Zantaz specializes in technology that provides e-discovery capabilities to an enterprise. Companies that have archival data on tape or disk storage systems need to be able to retrieve that data in a timely fashion to comply with some state and federal statutes. They may also have to get to the data if the company is involved in a lawsuit and parties to the suit seek information, a process called discovery. A change in U.S. rules for criminal procedures that took effect Dec. 1 places new requirements on companies to accommodate e-discovery requests.Zantaz and Singlecast have partnered for two years through a technology licensing agreement to provide compliance review tools for Zantaz Enterprise Archive Solution and, more recently, a Zantaz product called First Archive. Zantaz now plans to incorporate Singlecast’s technologies across its entire content archiving product line.The proliferation of e-mail places new demands on companies to archive e-mails in the event they are needed in e-discovery, said Brian Babineau, an analyst with Enterprise Strategy Group (ESG), a market research company. Zantaz technology classifies e-mail for storage purposes at the moment an e-mail is created, making them easier to find in the archive when needed. ESG estimates that over the next four years, e-mail archives will grow by a compound annual rate of 68 percent. Technology Industry
