Homeland Security

Atos - Homeland and Security

We support the government’s homeland security needs across its departments and agencies. We work securely, professionally, and sensitively – and we deliver results.

Secure Intelligence Agency (SIA)

The Security Service protects the UK against threats from espionage, terrorism and sabotage.


We provide a range of IT services for SIA. Although our work has significant impact, the details are sensitive.

UK Border Agency

The UK Border Agency (UKBA) is one of the largest law enforcement organisations in the UK, with a critical role in homeland security.


We help the UKBA achieve its objectives, by optimising its technology and processes.


We have transformed the Agency’s business efficiency – delivering savings of £100m over six years – by providing innovative and highly cost efficient IT shared services to 24,000 users. Those services are enhanced by our application management and infrastructure hosting capabilities.

Atomic Weapons Establishment

The Atomic Weapons Establishment (AWE) provides and maintains the warheads for the UK’s nuclear deterrent, Trident, and is critical to the country’s defence.


Atos improves operational efficiency at AWE, implementing innovative software solutions and processes for design and manufacturing.


We are also discussing the provision of other IT services for the future where we have a strong reputation in the public sector: desktop management, gateways, network and communications, and application management, for example.
