The Ministry of Defence

The Ministry of Defence (MOD) is the British government department responsible for implementing the defence policy set by Her Majesty's Government and is the headquarters of the British Armed Forces.  Its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability.  

What the MOD says about our work

We received an excellent service from boxxe and greatly appreciated their flexibility in helping us achieve our aims for this project in a very limited time frame before the submarines went back out to sea.  We have an additional four submarines which will require Flagstone installations during the next 12 months and fully intend to return for boxxe to do this for us.”

Assess the technology

The MOD needed twelve encryption solutions for submarines that were being upgraded.  The encryption assignment was commissioned by the MOD Abbey Wood, Bristol – home to the Tomahawk Land Missile Attack Project. 

A preferred encryption solution for the laptops, based on submarines at HMNB Clyde, Faslane, and HMNB Devonport, Portsmouth, had already been chosen and boxxe’s advice was sought as to whether this was suitable for the project in question.


Flagstone Enhanced

The solution chosen was Stonewood Flagstone Enhanced.  One of boxxe’s security consultants discussed the feasibility of this project at length with the client and confirmed that it was realistic to achieve what was required for those devices and the data they access and store.


Tenancy to tenancy migration

 Because they were in use, the submarines requiring the installations were only available at specific times and places.  To accommodate this, we put forward a series of dates when a consultant could visit each naval base to complete the work within the agreed time.

The first installation of Flagstone Enhanced, was onto laptops for a submarine at HMNB.  The consultant also visited the training facility to ensure that everything was in place to facilitate an installation.

A second installation of Flagstone Enhanced onto four laptops for one UK submarine and the training facility at HMNB Clyde was completed shortly afterwards.  Finally, another eight laptops were successfully installed on three submarines at HMNB Devonport.
