Protegrity Awarded Patent on Database Key Rotation Model

Highly Secure Database Key Rotation with Zero Downtime

Stamford, CT March 26, 2008 - Protegrity Corporation, the leading provider of Data Security Management solutions to the enterprise, today announced at the SecureWorld Expo in Boston that it has been awarded a patent for database key rotation that allows for zero application downtime. United States Patent 7,325,129, developed by Protegrity’s Chief Technology Officer Ulf Mattsson, delivers a continuous process for changing encryption keys in relational databases ensuring initial encryption, real time updates, and on-demand key changes can all occur without ever needing to take business mission-critical systems offline. The patented technology, available across Protegrity’s Defiance® Data Protection System solutions, extends customer control over data security management while ensuring Service Level Agreements are no longer violated due to key rotation downtime demands. The amount of time it takes an organization to comply with PCI and other data security focused regulations can be greatly reduced and enterprises will benefit from an increase in application availability without having to compromise database security. “With this patented technology, Protegrity customers gain another practical layer of control over enterprise-wide data security,” said Ulf Mattsson, Chief Technology Officer of Protegrity. “Database key rotation with zero downtime gives our clients a powerful new way to secure their databases while complying with data protection regulations with no impact on essential business processes.”
