Radiant's Cloud and Network Achieve PCI DSS Compliance

Vancouver, Canada, March 19, 2012 - Radiant Communications Corp. (“Radiant”) (TSX-V:RCN), a leading provider of managed network and cloud hosting solutions for medium-size enterprises, today announced that it has achieved Payment Card Industry Data Security Standard (PCI DSS) version 2.0 Compliance for Service Providers.

Radiant is now one of a select few service providers in Canada to have achieved PCI DSS compliance of both their core network and enterprise cloud computing environments.

The independent PCI Security Standards Council was created by five global payment brands, including Visa, American Express and MasterCard, to develop comprehensive standards to improve the security of payment card transactions. According to Visa's Cardholder Information Security Program, all merchants and members are required to use PCI DSS compliant service providers.

“Protecting the integrity of confidential data and an organization's reputation is of critical importance in today's network-centric world,” said Radiant President and CEO Paul Healey. “Achieving compliance with one of the highest security standards in the industry gives our customers confidence about the security, integrity and privacy of data transmitted through Radiant's network and cloud infrastructure.”

PCI DSS compliance is another example of the company's continued commitment to providing its customers with the most secure, reliable and scalable IT infrastructure services in the industry.
