Autonomy Provides Pan-Enterprise Search to Deloitte Luxembourg

Leading Professional Services Firm to Boost Productivity with IDOL

CAMBRIDGE, England and SAN FRANCISCO, March 8, 2011 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that Deloitte
Luxembourg has selected Autonomy's Intelligent Data Operating Layer (IDOL)
for pan-enterprise search. IDOL enables companies to enhance client service
by boosting efficiency, helping to avoid duplication of effort, eliminating
knowledge gaps, and unlocking information assets that have traditionally
remained untapped. Autonomy's unique conceptual capabilities, language
independence, scalability, and the ability to connect to virtually every
repository, including internal databases, the web, email and SharePoint, are
further advantages of the software.

"Due to its exhaustive industry expertise and know-how, Deloitte
Luxembourg has a vast pool of information to manage," commented Laurent
Brochmann, CIO at Deloitte Luxembourg. "Knowledge is one of our most
important assets but the geographical and language barriers have
traditionally been an obstacle to maximizing its full potential through
technology. Autonomy's unique meaning-based technology will enable us to
better manage information and knowledge within the firm to increase
productivity."

IDOL will equip its users with conceptual access to all structured,
semi-structured and unstructured content in the organization, enabling them
to form a well-educated and holistic view of a matter. Unlike legacy
solutions, IDOL can extract meaning from information across different
formats, languages and locations and identify links between disparate
documents and experts. Thus, for example, a user compiling a report for a
multi-national corporation, can find relevant content be it in English,
French, German or Italian, and further identify the best SMEs in the
organization to collaborate with. By automatically generating a profile of
each user in the organization, based on their explicit and implicit history,
IDOL is uniquely able to bring experts together for more efficient
resource-allocation. This helps the creation of virtual workgroups, and
encourages communication, knowledge-sharing and collaboration. Deloitte users
will also benefit from automatic news feeds about selected areas of interest,
as IDOL's 'Agents' functionality helps keep them abreast of relevant industry
developments.

Autonomy will further collaborate with Deloitte to fast-track its
technology to Deloitte Luxembourg's extensive customer base, thus helping to
ensure better operational efficiency, accuracy, transparency and information
governance for Deloitte Luxembourg customers.

"Autonomy solutions are used by more than 1,800 professional services
firms of all sizes worldwide, including the Big Four accounting firms," said
Eric Rousseau, Regional Manager Benelux at Autonomy. "As the only vendor that
offers a seamlessly connected and comprehensive set of information management
and governance tools, Autonomy is the preferred partner for professional
services firms as it enables them to derive optimal value from the collective
knowledge of their employees. We are delighted that Deloitte Luxembourg has
selected Autonomy's IDOL to underpin its pan-enterprise search."
