Guidance Software Inc. (NASDAQ: GUID), the World Leader in Digital Investigations™, today announced a game-changing Pay-Per-Use pricing model that enables organizations to use its industry’s leading EnCase® eDiscovery on a case-by-case basis.

Guidance Software now offers organizations the option of paying for only what they use, with charges tied to the amount of data searched, collected, processed, and output into load files. Pay-Per-Use pricing enables them to allocate litigation costs through internal charge-backs, and to seek insurance reimbursement for electronic discovery costs, with monthly invoices that break down charges on a per case basis.

“We want every organization to experience the benefits of using EnCase eDiscovery,” said Victor Limongelli, President and CEO of Guidance Software. “Pay-Per-Use pricing now makes our industry-leading solution available to those who pay for litigation costs through operating budgets. With EnCase eDiscovery, every litigant can build a proven, credible, and defensible in-house eDiscovery process.”

With Guidance Software’s Pay-Per-Use pricing, customers pay no upfront license fees. Pricing is tiered – the higher the annual dollar commitment and the longer the term committed, the lower the pricing. Customers get the same EnCase eDiscovery software that perpetual license customers do – installed behind the firewall, and providing unmatched search, collection, and processing of electronically stored information.

Guidance Software will continue to offer EnCase eDiscovery on a perpetual license basis for those with access to capital budget dollars. This will continue to be the most cost-effective option for many companies, in particular those with extensive litigation, and it is available to Pay-Per-Use customers at any time.

Last month, Guidance Software received the highest ranking (Top 5 Provider) in the eDiscovery Software Providers Category of Socha-Gelbmann's 2008 Electronic Discovery Survey. Earlier this year, Guidance Software also received the highest possible rating in Gartner's MarketScope for E-Discovery and Litigation Support Vendors, 2007. The Gartner report is available, compliments of Guidance Software at www.guidancesoftware.com.
