"The trend to attempt to unite all disparate systems and information regardless of format or location is reaching primetime status, and companies are rapidly standardizing on Autonomy's Meaning-Based Computing platform, IDOL, to process all enterprise information," said Mike Lynch , CEO of Autonomy. "Given a market plagued with vendor instability and merger and acquisition activity, Autonomy's rapid and persistent growth, its unrivalled financial performance, and the fact that we own all our technologies continue to position us as the vendor and partner of choice."

Autonomy's strategic value in the enterprise has risen with the proliferation of unstructured information and with changes in regulatory requirements. Autonomy's Meaning-Based Computing enables computers to understand the relationships that exist between disparate pieces of information and perform sophisticated analysis operations with real business value, automatically and in real-time.
