Autonomy Announces Availability of Idol-Based CA Message Manager

Customers Benefit from New Advanced Functionalities, an Order of Magnitude Increase in Performance, and Conceptual Understanding of Information

CAMBRIDGE, England and SAN FRANCISCO, July 2, 2010 - Along with the completion of the acquisition of CA Technologies'
Information Governance business, Autonomy Corporation plc (LSE: AU. or AU.L)
today announced that its unique meaning-based pan-enterprise search platform,
the Intelligent Data Operating Layer (IDOL), now powers the recently-acquired
Message Manager. This product has been renamed Autonomy Message Manager.
Autonomy announced its acquisition of CA Technologies' Information Governance
business on June 9, 2010.

The integration of Autonomy IDOL into Message Manager brings advanced
automation to information governance tasks based on IDOL's ability to
understand the meaning of information. This significantly reduces the levels
of manual effort for classifying, monitoring and managing large and growing
volumes of data. New and existing Message Manager customers will benefit from
the same powerful enterprise search engine in use by more than 17,000
corporate customers, acknowledged by leading industry analysts as the "clear
leader in the enterprise search market."

"The rapid integration of Message Manager with Autonomy IDOL is
impressive, and a sign of good things to come from the recently completed
transaction," said Reed Irvin, Vice President, Information Governance of
Autonomy. "The combination will empower our customers with advanced
capabilities that will reduce their operating costs, while enhancing both
their productivity and ability to comply with corporate governance."

Customers who wish to take advantage of IDOL's breadth of connectivity to
repositories and applications, as well as a myriad of rich functions from the
IDOL platform, can do so for an additional cost. The new add-on capabilities
include access to more than 400 connectors and over 1,000 file types,
including text, audio and video, as well as advanced multilingual
capabilities and hundreds of new functions, such as Automatic Clustering and
Idea Clouds.

"With the tightened global government regulations around information
governance and eDiscovery, organizations of all sizes must take a very
careful approach to email archiving, and require a platform that enables them
to bring meaning to all data, regardless of its format or location," said
Neil Araujo, CEO of Autonomy iManage. "Autonomy is the only company that is
truly in a position to meet the demands of this new reality - and is the
obvious choice for any organization looking to standardize on one platform to
archive, find, manage, and process large volumes of information quickly and
intuitively."
