Defence Fixed Telecommunications Service (DFTS)



The Defence Fixed Telecommunications Service (DFTS) is delivered by BT on behalf of the Ministry of Defence (MOD) and delivers proven value for money under a single supplier agreement.

It began back in 1997, and it shows how a public private contract can develop into a true partnership.

National Defence relies on swift and secure access to key people and up-to-date information. DFTS helps the MOD in its most critical activities, like pinpointing organisations and people who make and plant Improvised Explosive Devices, or speeding up transfers and treatment of frontline casualties.

At the same time, DFTS delivers proven value for money. Initially we replaced 19 networks with one secure network, helping the MOD to save £700 million; today savings are on track to top £800 million. As a fully managed service it eliminates technology procurement risks, while BT people work hard to deliver a great service.

Our secure voice, data and video services are used every day by the MOD, Defence Industry contractors and Partners Across Government (PAGs). These services span the full range of secure access and encryption levels, from OFFICIAL to SECRET and above. We manage 970 sites and over 225,000 users for the MOD. Our VPN is one of the largest in Europe carrying more than 750,000 calls a day.

Our Enterprise Gateway Service (EGS) processes around 300,000,000 emails every year, protecting Defence users by filtering approximately 60% which fail the security policy check.

Scale is only one side of the story. No less essential to the MOD is the assurance DFTS offers on speed, flexibility, and security. For example, being able to set up secure video conference calls at short notice. That includes people in multiple locations, offering rapid access to the right data.

MOD has chosen to extend the contract twice. Most recently, in 2010, it was extended to 2015. Renowned for providing secure communications to key players in Defence, we understand security & resilience are their absolute number one priority. We’re proud of this and the impact DFTS has made across UK Defence..
