As a leading payment gateway managing over 247 million online payment transactions for more than 136,000 merchants each year, Authorize.Net is committed to helping its merchants protect themselves from security threats such as phishing or ID theft. Implementing Comodo's Identity and Trust Assurance (ITA) technologies provides a strong foundation of protection for Authorize.Net merchants by offering the strongest levels of encryption available, while providing validation of legitimacy to end users.

"Authorize.Net is always looking for new opportunities to provide our merchants with ways to enhance the security of their business," said Roy Banks, Authorize.Net president. "With an SSL certificate issued by Comodo, merchants will be assured that all data passing between their Web site and the Authorize.Net Payment Gateway remains secure and confidential. In addition, by displaying the Comodo TrustLogo Site Seal, our merchants are sure to boost their customers' trust and confidence."

James Langman, director of business development at Comodo, said, "As a leading Certification Authority, Comodo is pleased to be chosen as the best fit to provide critical security solutions to Authorize.Net merchants to enhance end-user trust. Together, Authorize.Net and Comodo continue to deliver innovative new identity and trust assurance solutions that empower e-commerce merchants to increase Web traffic, conversion rates and ultimately revenues.
