CommVault Rated "Promising" in Leading Analyst Firm's E-Discovery Software Product MarketScope

OCEANPORT, N.J. — January 14, 2009

• CommVault (NASDAQ: CVLT) has been rated Promising in Gartner's MarketScope for E-Discovery Software Product Vendors, published December 17, 2008¹. According to the report, "[t]he e-discovery market includes products and services that allow electronically stored information (ESI) of all types to be identified, preserved, collected, processed, reviewed, produced and managed over a period of time."
• To outline the changes in the 2008 MarketScope for E-Discovery Software Product Vendors, Gartner noted that "[t]his year's MarketScope will be different to last year's in two significant ways. First, service providers will not be included in this year's MarketScope evaluation. Second, the research note will not include vendors with under $10 million in total revenue."
• CommVault® Archive and Search software, two modules that are part of the CommVault Simpana® data and information management suite, form the backbone of the CommVault Simpana® eDiscovery solution allowing customers to capture, investigate, preserve and disclose information simply and securely. These capabilities help legal teams control eDiscovery risk as well as enabling IT departments to control data growth through deduplication. Both can lead to significant reductions in the overall cost of records retention and discovery.
• With newly adopted US changes to the Federal Rules of Civil Procedure (FRCP), and the growing worldwide trend to preserve ESI as evidence, organizations are realizing that ESI is no longer limited to just obtaining and securing on-line email. CommVault Search software ensures rapid discovery of information across a wide range of content sources, and across any tier of storage in the enterprise, while CommVault Archive software allows specific retention and security policies to be defined in one application that span different data types and repositories. Using Simpana software ensures that proper data retention and disposition is managed. More importantly, in the event of litigation, it allows for a legal retention hold to be placed across relevant data, multiple sites and geographies from within one user interface.
• Gartner's MarketScope notes that "[s]pending on electronic discovery (e-discovery) software and services offerings is forecast to grow by between 25% and 35% annually through 2012." The report further provides that "[e]nterprises purchasing e-discovery software can reduce the costs of litigation by improving their control over unstructured content, and semi-structured content, most notably e-mail. Also, they can cut costs and risks by taking control of litigation hold, litigation-hold tracking, file collection, file processing and legal review instead of outsourcing these functions."
• As organizations evaluate the offerings of vendors in this market, CommVault Simpana software offers several key advantages inherent in CommVault's Singular Information Management® approach. A powerful, yet simple single platform methodology allows organizations to quickly address the mounting requirements for long-term data retention and compliance management, so that customers benefit from significantly reduced risk, ease-of-administration, enterprise-class scalability and reduced overall cost and complexity.

• "The true cost of eDiscovery can be debilitating, between the risks of fines and sanctions, the drain on corporate resources, lost productivity from legal fishing expeditions and the cost of outsourcing eDiscovery actions," said Simon Taylor, senior director of CommVault's Information Access Management group. "By offering businesses the ability to search and discover any electronically stored information across the enterprise, managing its retention, preservation and ultimately destruction, CommVault continues to help customers improve legal review efficiency and reduce the overall risk and cost of eDiscovery. Our commitment to driving innovation in this market is second to none and in my opinion this is reflected in our rating in the Gartner MarketScope for E-Discovery Software Product Vendors."
