Quest Software Inks Deal to Acquire PassGo Technologies

Quest Software, Inc. (Nasdaq:QSFT) today announced that it has signed an agreement to acquire PassGo Technologies Limited, a privately-held, Britain-based leader in access and identity management solutions. The addition of PassGo’s market-leading identity management and compliance products to Quest’s existing user authorization and authentication product set means customers will enjoy a more comprehensive method of managing users and controlling access in multi-platform environments including Microsoft’s Active Directory, Unix and other platforms including IBM zSeries and iSeries (S/390 and AS/400) systems. "As our customers face the challenge of providing appropriate user access and better controlling what users can do when they have it, their IT departments are looking for solutions to help them better manage access and authorization,” said Vinny Smith, CEO of Quest Software. "Over the past couple years Quest has increased its focus on expanding our Active Directory-based identity management strategy to non-Windows systems, and the addition of PassGo is the next step in our effort to meet customer needs in areas like security and compliance.” The deal is expected to close in early 2008. In his new role as Vice President, PassGo Products, PassGo CEO John Rainford will report to Steve Dickson, Vice President and General Manager of Quest’s Windows business unit. "I’m very pleased to complement our existing identity and access management offerings with the addition of PassGo,” said Dickson. "While we remain a Windows-centric business, we can now better address the needs of enterprises managing heterogeneous environments with PassGo’s mature, multi-platform solutions.” "PassGo is delighted to enhance the capabilities of a market-leader in access and identity management while at the same time maintaining high-level satisfaction and support for our current customers,” said Rainford. "This increases PassGo’s ability to reach new customers in new markets and gives Quest a new presence in industry modeling tools like Gartner’s ‘Magic Quadrants’ for Web Access Management and Enterprise Single Sign-On.” About Quest Software, Inc.
