Read full description

Réunion is a communications application that provides secure messaging features for organizations that require private system topologies. Réunion offers an intuitive interface token based security removing the need for legacy password paradigms for authentication. The Réunion application is paired with a server platform, that typically resides in a controlled data center or private cloud. Réunion has the ability to federate with legacy services and protocols to assimilate these data sets into a secure environment. Réunion is ideally suited for regulated industries requiring private cloud technologies that meet compliance requirements. Réunion is actively under development, currently integrating an email-like service and a demonstration of the EasyCrypt solution. Many other functionalities are in progress such as an end-to-end encrypted instant messaging module, and later a compliant video conferencing module for Fintech and public service organizations.
