VGS Tokenization replaces sensitive values with aliases and stores the original data in a VGS Vault. Organizations can tokenize payment-card data and other sensitive information, including personal and health data, then use aliases in their own systems. The service supports configurable alias formats and storage behavior, including format-preserving options. VGS Collect can send form data to the Vault API, where aliases are returned for use in an application. Authorized workflows can retrieve original values when needed. VGS presents tokenization as a way to reduce exposure of sensitive data and PCI DSS scope.
