Visa USA's Cardholder Information Security Program (CISP) (mandated since June 2001) is intended to protect Visa cardholder data 'wherever it resides', ensuring that members, merchants, and service providers maintain the highest information security standards. To achieve compliance with CISP, merchants and service providers must adhere to the Payment Card Industry (PCI) Data Security Standard, which offers a single approach to safeguarding sensitive data for all card brands. This standard is a result of collaboration between Visa and MasterCard, and is designed to create common industry security requirements that incorporate the CISP requirements.
