Defence Gateway: The Secure Digital Portal for Defence for Personnel and Partners

Defence Gateway is the secure online central gateway that the Ministry of Defence (MOD) maintains and uses in the United Kingdom to allow users of Defence personal devices to access Defence applications and services. The platform will be the primary digital portal for British Army personnel, Royal Navy, Royal Air Force personnel, MOD Civil Servants, reservists, cadets, veterans and approved Defence partners as of 2026.

The Defence Gateway (DG) has become a key element of MOD’s digital estate as remote working, digital collaboration and cyber security have become increasingly important in Defence operations. It enables users to safely gain access to email, training sites, HR services, welfare, logistics and collaboration systems without needing a Government issued device.

Defence Gateway offers the following key services:

• Official email and calendar systems.
• Human resources administration and human resources management
• Joint Personnel Administration (JPA)
• Training and e-learning platforms
• Career management tools
• Logistics and supply chain applications.

This has earned the Defence Gateway one of the most popular digital platforms in UK Defence.
