Introducing ANTENNA

Designated as Critical National Infrastructure; ANTENNA is a shared service that saves taxpayer money, enables collaboration and improves citizen access to services.

Delivered via a secure, private, cloud-based enterprise platform and network; ANTENNA is hosted in highly secure, resilient Government accredited data centres.

ANTENNA is supported by a dedicated service-desk, with a project office and professional services team based in Westminster; manned by the UK’s largest team of SC and DV level security cleared engineers.

ANTENNA provides services to nearly 40,000 central government users and is saving millions of taxpayers’ money.

In partnership with the Cabinet Office

Designed in partnership with the Cabinet Office, the ANTENNA programme provides a pathway to digital and data transformation via highly secure community cloud.

ANTENNA allows government departments and agencies to utilise legacy equipment while providing an efficient, low-cost route to procure and transition to the latest highly secure, feature-rich and sustainable technology, delivering upon the government’s Digital, Data and Technology (DDaT) transformation strategy.

The ANTENNA programme was formed because we wanted to share our ICT infrastructure with other Departments in a way that’s not been achieved before. The approach taken by the Cabinet Office meant that by utilising existing equipment, we could reduce costs, improve service and provide expert support to Departments in a way that they’ve not experienced previously,
