Sitehop, the Sheffield-based cybersecurity specialist, has unveiled the world’s smallest post-quantum encryption device, designed to protect critical national infrastructure from next-generation cyber threats.

The pocket-sized device, SAFEcore Edge, is engineered and manufactured in the North of England. It aims to secure "edge" locations—remote sites such as oil platforms, autonomous vehicles, and rural bank branches—where traditional, bulky security hardware cannot be deployed.

As quantum computing advances, traditional encryption methods are increasingly viewed as vulnerable. Sitehop’s hardware-enforced solution claims to provide security that is 1,000 times faster than software-only alternatives, ensuring that data speed is not sacrificed for safety.

Melissa Chambers, CEO of Sitehop, said: “As cyber threats escalate, securing the communications that underpin our critical infrastructure, financial system and government networks has never been more important. SAFEcore Edge is British-engineered sovereign technology that brings post-quantum encryption to every point on the network.”

The technology is already being trialled by an international IT services provider and has been deployed by a global telecommunications carrier across seven countries. The device is particularly relevant to the financial sector, where it offers "sub-microsecond" encryption for high-frequency trading.

Ben Harper, CTO, added: "It delivers hardware-enforced, ultra-low-latency encryption that protects sensitive data without compromising performance, whether securing remote operations or high-speed financial transactions."

Sitehop will demonstrate the device at Cyber UK, the government's flagship cybersecurity conference, in Glasgow next week.
