Financial services

As cyber-attacks become increasingly sophisticated within financial services, building resilience against them requires a combination of measures that stop attacks from occurring, building contingencies and deploying cyber security technology.

Sensitive transactions and customer data

If you’re a bank with multiple branches, it’s likely you share sensitive transaction and customer data with the head office. You’re probably operating a network of ATM machines that transmit real-time data to your secure network. Your security cameras could be live streaming with direct connections to your internal systems. And you’re also backing up data regularly in case the worst happens. All these areas are vulnerable to cyber attack, and traditional protection layers, such as firewalls, aren’t enough to protect against increasingly sophisticated hackers.

The securest level of protection

That’s where Oakdoor Data Diodes come in. Considered the securest level of protection when transferring sensitive data, protecting systems or segregating networks, the defence and security industry has used data diodes for decades. They allow specified types of structured data into or out of the network – a one-way gate that implements pre-defined security and authentication protocols. This means full control and security over every piece of data transferred, eliminating the risk of viruses or hackers entering your systems.

Developed in partnership with UK Government

Now, our family of data diodes, developed in partnership with UK Government, offer a cost-effective, simple solution. At the heart of Oakdoor 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 are hardware-based devices that are 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.

Critical national infrastructure

An efficient way to protect critical infrastructure cluster systems is to introduce a hardware-based cybersecurity solution at the network perimeter.


By allowing only approved types of data traffic and one-way data flows, our hardware-based data diodes prevent cloud cyber attacks.
