PKWARE Releases New Versions of PKZIP for iSeries and zSeries

Newest versions enable efficient and secure information transfer between datacenters and other computing users within, and outside, the Enterprise

Brown Deer, WI. (October 6, 2003). PKWARE, the leading provider of Trusted ZIP solutions for the Enterprise, today announced enhancements to its award winning PKZIP products for iSeries midrange systems and zSeries mainframes. The new functionality now enables datacenters to compress and secure files of virtually any size and number, and to automatically create self-extracting files, making it easy to send large files across and beyond the enterprise. Secure ZIP(tm) files created by PKZIP for iSeries and zSeries can also be unzipped and decrypted by external Windows recipients using the freely available PKZIP Reader.

PKZIP for iSeries and PKZIP for zSeries are already used by 60 percent of the Fortune 100 companies, including 12 of the top 14 financial institutions in the U.S. and over 20 percent of all mainframes worldwide. The new features strengthen the interoperability of ZIP files across computing platforms, making it easy to transfer data efficiently and securely between mainframes, servers and desktops.

"PKZIP enables significant reductions in storage, bandwidth and processing requirements for midrange and mainframe computing platforms," said Tim Kennedy, President and COO of PKWARE. "Our latest versions of PKZIP greatly enhance the ability of datacenters to transfer information efficiently and securely with other users within the enterprise -- as well as the extended enterprise."

PKWARE's patent-pending Secure ZIP technology combines encryption with the zipping process, allowing organizations to realize tremendous savings in bandwidth, CPU cycle time, and storage. With the PKZIP cross-platform solutions, datacenters can now easily implement data security solutions that maximize their existing investments in computing, storage, and network infrastructures.

PKWARE today announced two other initiatives to extend the interoperability of the Secure ZIP file compression standard: New licensing programs for PKZIP Reader and Secure ZIP, and the PKZIP Reader Partner Program. The licensing program is intended to enhance interoperability among all ZIP users and vendors. The PKZIP Reader Partner Program provides organizations with a license to redistribute PKZIP Reader, the free unzipping and decrypting utility, to their business partners and customers. With PKZIP Reader, firms can quickly, easily and inexpensively extend their security initiatives to those in the extended enterprise.
