Panacea Card Data Scanner (pCDS) is a data discovery tool designed to identify cardholder data within specific environments to support PCI DSS compliance requirements, particularly Requirement 3.1 which mandates protection of cardholder data. The tool scans across private networks from a single machine deployment to locate payment card numbers and other sensitive customer information. pCDS uses algorithms to identify card numbers issued by major payment brands including American Express, Discover, JCB, MasterCard, VISA, and Diners. The scanner can be configured to search for additional types of sensitive customer information beyond payment card data. The tool provides database scanning capabilities across MySQL, MSSQL, Postgres, and Oracle databases at different levels of granularity. It identifies the scope of the card data environment to help organizations minimize fraud risk from unidentified cards present in service provider or merchant premises. pCDS operates through single machine deployment with scan execution capabilities across private networks. The tool is designed to provide resource and time efficient scanning functionality with an interface described as intuitive and easy to use.
