CAMBRIDGE, England and SAN FRANCISCO, June 1, 2011 -

- Autonomy IDOL to Help Enhance Information Discovery Capabilities at the
Department of National Defence

Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that the Canadian
Department of National Defence has selected Autonomy's Meaning Based
Computing platform, IDOL, as a key part of its Information Management and
Collaboration initiative. With Autonomy, the Department of National Defence
will be able to enhance its information discovery capabilities.

Autonomy IDOL performs conceptual and contextual analysis and probability
matching on information to find the meaning within and the
inter-relationships between disparate pieces of content. This unique approach
allows employees at global organizations to find and access the most
pertinent content, irrespective of languages, operating systems, and file
types. By supporting more than 1,000 different data formats, including
structured, semi-structured, and unstructured data, across 400 different
content repositories, Autonomy can search all categories of information in an
organization. IDOL is fault-tolerant using load balancing and mirroring,
highly scalable, secure, and has sub-second performance on billions of files.

"Autonomy's Meaning Based Computing platform is used by many government
agencies around the world to understand the meaning of their content and
identify patterns between distinct pieces of information," said Mike Lynch,
CEO of Autonomy. "Our technologies help them to better meet regulatory
compliance, while realizing cost savings and improvements in service delivery
to their citizens. We are pleased to help the Canadian Department of National
Defence to effectively leverage its information assets."
