SWIFTNet Mail SWIFT offers a secure person-to-person messaging service, SWIFTNet Mail, which went live on 16 May 2007. SWIFT clients can configure their existing email infrastructure to pass email messages through the highly secure and reliable SWIFTNet network instead of the open Internet.

In response, and to satisfy members' concerns about privacy, SWIFT began a process of improving its architecture by implementing a distributed architecture with a two-zone model for storing messages (see Operations centres). Concurrently, the European Union negotiated an agreement with the United States government to permit the transfer of intra-EU SWIFT transaction information to the United States under certain circumstances. Because of concerns about its potential contents, the European Parliament adopted a position statement in September 2009, demanding to see the full text of the agreement and asking that it be fully compliant with EU privacy legislation, with oversight mechanisms emplaced to ensure that all data requests were handled appropriately. An interim agreement was signed without European Parliamentary approval by the European Council on 30 November 2009, the day before the Lisbon Treaty—which would have prohibited such an agreement from being signed under the terms of the
