Defence and armed forces – guidance

Defence Gateway

The Defence Gateway (DGW) is the Ministry of Defence’s mandated Single Sign On solution for extranet sites.


The Defence Gateway controls access to a cloud hosted environment for a number of websites, applications and mobile applications. It has been developed to provide simple and secure access to these resources so that any member of defence can securely collaborate, communicate and share information over the internet from any device.

The DGW draws on the principles and technologies the Cabinet Office (CO) commends in its ICT Strategy. Its websites and applications are hosted on a private cloud delivered and supported under contract. This represents a step change in the method of procuring and delivering a defence wide ICT environment and does so with the advantages of global availability free from the constraints of dedicated networks and hardware.

The DGW is provided as a service for defence by Web Exploitation (Web Ex), Army information Services (AIS), Army HQ. It is available for hosting and providing access to websites and applications as well as for the exploitation of these resources.

Websites and applications available behind the DGW include:

  • a mobile applications store for hosting and accessing defence mobile applications

  • Armynet, a website providing information to the Army community

  • an email service

  • ATG(A), the official Adventurous Training portal for defence

  • Sharepoint

  • Acquisition Operating Framework (AOF), a website defining how defence conducts, governs and controls acquisition

  • UK Defence Standardization (DSTAN), a website providing performance specifications for the delivery of military capability

  • Royal Military Academy Sandhurst (RMAS), an application providing information sharing and virtual learning for cadets at Sandhurst

  • a content management system for the development of websites

Future websites and applications planned for the DGW include:

  • a website providing information on the Defence Interactive Operating Model (DIOM)

  • ‘Westminster’, an application for the management of cadet activity

  • Social Enterprise Tool, to enable improved collaboration

  • Best Practice Portal, a Director General Transformation sponsored website to encourage sharing best practice across defence

  • Bookstore, a bookstore providing defence books, publications and journals for reading on line or downloading
