Waarp is an Open Source Managed File Transfer Solution.

Waarp Platform is an open source project aimed at improving the reliability, security, monitoring and integrability of file transfers in a scalable IT system. 

It fosters interoperability between file transfer protocols (FTP/FTPS, SFTP, HTTP/HTTPS, AS2/AS3, EBICS/TS).

It is composed of multiple related components that can be operated together or independently:

  • Waarp R66: an open file transfer monitor. It is the core component of the Platform and implements the R66 protocol, which is designed for performance and scalability to ensure the full reliability of internal and external file exchanges.
  • Waarp Gateway FTP: an open FTP(S) server with an extension to serve as a gateway for the R66 protocol with the same requirements for scalibility.
  • Waarp Gateway HTTP: an open HTTP Server but only intend to be used as a Gateway to the R66 protocol (this component is not yet publicly available).

Market Readiness Synthesis

Initially developed in 2007 for the French Ministry of Finance, then for the Gendarmerie Nationale, Waarp is a mature open source managed file transfer solution. A company of the same name was created in 2011 to hold the project leadership, productise it and provide professional support subscription plans. The company is adequately financed through its support activity representing 80% of its revenue from a dozen large customers, and public R&D subsidies. Waarp is essentially used by large customers with a need for large file transfer volumes with high privacy and security. Waarp competes against Axway in France and GoAnywhere in the US.
