In its MarketScope assessment, Gartner, Inc., an independent industry research and advisory firm, provides an evaluation of a marketplace, in this case enterprise backup/ recovery software, and analyzes how certain vendors measure against criteria for that marketplace. Vendors were evaluated against six criteria: market understanding, marketing strategy, offering (product) strategy, product/service, market responsiveness and track record, and marketing execution. The vendors were given one of five ratings: Strong Positive, Positive, Promising, Caution or Strong Negative.

"According to Gartner, vendors who receive a "Strong Positive" rating are solid providers of strategic products, services or solutions. They recommend existing customers to continue investments, and potential customers should consider the vendor a strong strategic choice," said David West, vice president of marketing and business development of CommVault.
