PRESS RELEASE

CHICAGO (November 11, 2010) – Trustwave, a leading provider of information security and compliance solutions, has entered into a partnership with CyberSource Corporation. Under the terms of the agreement, Trustwave will have the opportunity to provide Payment Card Industry Data Security Standard (PCI DSS) compliance validation solutions to CyberSource’s merchant customers.

PCI DSS compliance is a requirement for all organizations that accept credit cards or debit cards as a form of payment and has been endorsed by all of the major card brands, including Visa Inc., MasterCard Worldwide, Discover Financial Services, American Express, and JCB International.

In order to assist in the compliance efforts of merchants, CyberSource has engaged Trustwave to provide its merchants access to TrustKeeper' PCI, Trustwave’s industry-leading PCI DSS compliance web portal.

TrustKeeper PCI facilitates PCI DSS compliance validation in an easy and efficient manner. Using its dynamic PCI Wizard, merchants answer a personalized questionnaire that simplifies the complex terminology of PCI DSS compliance requirements. TrustKeeper PCI also helps merchants complete the PCI Self-Assessment Questionnaire, schedule required vulnerability scans, and receive their PCI DSS compliance certificate.

Additionally, after a simple download, merchants are provided access to TrustKeeper Agent which serves as a beaconing device that performs compliance checks on merchants’ payment systems and sends that data back to TrustKeeper PCI. This prevents merchants from unintentionally storing unencrypted cardholder data or track data.

As an additional component of the partnership, TrustKeeper PCI provides online educational and compliance tools for merchants to help build awareness of the PCI DSS requirements. Online video tutorials guide merchants through general cardholder data security, the PCI DSS, and how to comply with the standard. On-demand help, tutorials and tools such as TrustKeeper PCI’s Security Policy Advisor and Security Awareness Education help merchants efficiently complete PCI DSS validation.

“Working with Trustwave, we believe we can offer our merchant customers a simplified path to PCI DSS compliance validation,” said Michael McGirr, Director, Global Risk at CyberSource. “We are delighted to be partnering with Trustwave, long one of the leaders in payment card security compliance management.”

“Trustwave’s compliance suite is specifically geared to help businesses understand and achieve PCI DSS compliance,” said Doug Klotnia, Executive Vice President of Product and Strategic Sales at Trustwave. “CyberSource merchants will be provided with a holistic approach to PCI DSS compliance validation which includes education, support and ultimately, compliance.”
