Military cyber security companies and contractors are becoming increasingly instrumental to the digital safety of modern armed forces. Cyberattacks are a common risk facing both defence and non-defence sectors and are often termed low-intensity warfare although such attacks can cause major economic, political, and military losses. Countries and militaries can protect themselves from cyberattacks through cooperation and by gaining support from organisations such as NATO to develop collective defences.

Need for cyber security measures in defence


Countries that lack cordial political relations often target each other’s military, financial and utility facilities through cyberattacks. Cyberwarfare enables the offender to cover the tracks while causing serious disruption to a country’s ability to operate or retaliate. Countries, therefore, need to heavily invest in developing counter cyber-operations abilities.

Cloud and edge computing

Cloud and edge computing enable faster data processing, increased data storage and reduced latency. These technologies, however, remain a major target for cyberattacks by enemies. Bolstering cyber security in such cases becomes imperative to ensure forces have access to the required data and resources.

Protecting critical infrastructure

Power and energy utilities are part of the critical infrastructure of a country, which have come under attack in the recent past. The attack surface area of such facilities continues to grow as sensors and other equipment used across the network provide an opportunity for attack.

Cyber security contractors for the US military

Lockheed Martin is one of the major cyber security contractors for the US military providing products and services that help counter cyberattacks. The company’s products and services include cyber kill chain, digital forensics, and cross-domain solutions.

General Dynamics is another major contractor that provides encryption, multilevel security, cross-domain security and secure communications systems.
