Modirum offers an XML-based messaging protocol known as Three-Domain Secure (3DS), designed to authenticate cardholders during online transactions. This system is particularly beneficial for organizations and enterprises that handle card-not-present purchases, as it helps mitigate the risk of unauthorized transactions. By facilitating secure communication between cardholders, merchants, card issuers, and payment systems, 3-D Secure significantly reduces fraud and chargebacks, shifting responsibility from merchants to issuers.

In addition to its core authentication features, Modirum enhances business operations through workflow automation and integrated payment solutions. Users can securely store and manage data with advanced search capabilities, ensuring quick accessibility for teams. The service caters to a wide range of organizations, including small businesses, nonprofits, and government entities, while providing support in English and various training options, including documentation and in-person sessions.
