CAMBRIDGE, England and SAN FRANCISCO, July 1, 2010 /PRNewswire/ -- Autonomy Corporation plc , a global leader in infrastructure software for the enterprise, today announced that IDC, a leading research firm, reported that Autonomy owned the largest revenue share in the worldwide search and discovery market in 2009.

According to IDC's report titled Worldwide Search and Discovery 2009 Vendor Shares: An Update on Market Trends, Autonomy increased its market share lead to 15.3% in 2009. This share represents a 50% lead over the next closest keyword search competitor, Microsoft, and is nearly double that of the third place vendor, Google.

The IDC report, written by Sue Feldman, Vice President for Search and Technologies, and Hadley Reynolds, Senior Analyst, states that Autonomy continues to be the largest enterprise supplier, using its search-based IDOL infrastructure to act as a foundation for content-centric and search-driven business applications including eDiscovery and compliance, Web content management, enterprise content management and rich media, search marketing, intelligence, call center and customer support, and traditional knowledge management applications.(1)

Businesses from every industry continue to turn to Autonomy to help them achieve what other technology companies fail to deliver on - identifying the meaning within all forms of information, in real-time, in order to protect and promote their organization, said Mike Lynch, CEO of Autonomy. Autonomy's unique meaning-based approach to information computing is what continues to fuel our rapid growth and clear market leadership, as validated by the recent IDC report on Search and Discovery market shares.

Autonomy's pan-enterprise search platform, the Intelligent Data Operating Layer (IDOL), performs conceptual and contextual analysis and probability matching on information to find the meaning within and the inter-relationships between and among disparate pieces of content. This unique approach allows global organizations to find and access the most pertinent content for business value or risk management, irrespective of languages, operating systems, and file types. By supporting more than 1,000 different data formats, including structured, semi-structured, and unstructured data, located across 400 different content repositories, Autonomy can search all categories of information repositories in an organization, enabling companies to maintain compliance with government regulations, such as the Federal Rules of Civil Procedure (FRCP). IDOL is fault-tolerant using load balancing and mirroring, highly scalable, secure, and has sub-second performance on billions of files.
