Defence and security

Modern cyber warfare and battlefield engagement rely heavily on digital networks and computer-based solutions. All elements of connected warfare, from aircraft carriers and armoured vehicles to satellites, drones and personnel on the ground, depend on trustworthy information handled and distributed quickly.

Thousands of systems and applications

The amount of data generated by the plethora of sensors and systems is growing exponentially, and it’s critical to have full control of all data streams to protect organisations against increasingly sophisticated network-based attacks.

At the same time, there are thousands of systems and applications that need to be kept up-to-date and monitored to reveal any suspicious activity. There’s also an increasing requirement for efficiency in operations, moving away from ‘air-gapped’ operations to more quickly import and export files securely and connect to outside networks, such as the internet, without having to maintain a large stock of secondary PCs.

A cost-effective solution

To mitigate these challenges while maintaining the highest levels of security that the defence and intelligence services require, the sector has used complex and expensive data diodes for the past two decades.

Now, our Oakdoor Data Diodes, developed in partnership with UK Government, offer a cost-effective solution.

At the heart of our Oakdoor Data Diodes lies an ingenious, simple design that’s not only secure, but fast and maintenance-free. And we’ve designed the diodes to achieve a price-point that yields an unrivalled return on investment.

The diode platforms hardware is CAPS approved by the UK National Cyber Security Centre (NCSC). The evaluation is incredibly rigorous, meaning Oakdoor is suitable for even the most sensitive operational environments.
