Companies and service providers that process card payment transactions that require storing and transmitting payment data, are required to meet strict technical and organizational requirements in order to protect the cardholder’s personal data. These requirements are defined in the Payment Card Industry Data Security Standard, or PCI DSS, and apply to all organizations that handle cardholder information for all major debit, credit, prepaid, ATM, and POS cards. Retarus’ data centers and communication services meet this IT security standard initiated by the four major credit card companies, American Express, MasterCard, Discover and Visa and it is considered one of the most secure and stringent standards in the world. Retarus is the first messaging service provider to be awarded the PCI DSS certification for its data centers and services, which has a key impact in all Retarus’ customers worldwide, as they will benefit from additional security when their data is processed and stored.
