We are Arqit


Our mission is clear: stronger, simpler encryption.

Arqit supplies a unique quantum-safe symmetric key agreement encryption platform, which makes the communications links or data at rest of any networked device or cloud machine secure against current and future forms of attack – even from a quantum computer. Arqit’s product, SKA Platform™, enables any device to download a lightweight software agent, which can create encryption keys in partnership with any number of other devices. The keys are computationally secure, optionally one-time use and zero-trust. SKA Platform can create limitless volumes of keys in limitless group sizes and can regulate the secure entrance and exit of a device in a group. SKA Platform is available as a Platform-as-a-Service or as a sovereign private instance.


Arqit confronts an existential
threat to the
hyperconnected world

The legacy encryption we all use was designed in the 1980s. It was never intended for use in our hyper-connected world. It has done a great job but it’s now failing us. We see breaches caused by its flaws daily. But there is a bigger problem. Quantum computing poses an existential threat to everyone’s cybersecurity.

In response, the world must begin a global upgrade to replace all encryption technologies. This is an upgrade unlike anything we have seen before. Patching, mending and taking risks with incremental improvements to public key encryption, which is no longer fit for purpose, is not the answer.

ORIGIN OF SYMMETRY Stronger simpler


Manual Key Delivery

Many governments and enterprises do not trust PKI in their core networks. Organisations with the most stringent security needs still rely on people to transport the cryptographic keys that protect their networks around the globe. Aside from the increased cost and environmental impact, manual key delivery introduces more vulnerabilities and results in poor key refresh rates. Our solution is both scalable and flexible for the connected digital world of today, and tomorrow.


Zero Trust

Protecting against current and future threats by removing the need for trusted third parties. Zero Trust is an architectural concept built around the idea that systems should not inherently trust any connection to a business system or application regardless of what trusted device or trusted network it originated from. Everything should be identity driven. This approach has led organisations to adopt PKI-based technologies to help secure authenticated users and authenticate devices and systems. It ironically also brings in an entire federated trust model with it.



SKA Platform puts a lightweight agent at any endpoint device. This software creates an unlimited number of symmetric keys with partner devices. The process is very simple, fast, and cloud-based. That’s how we create a backbone of secure keys within data centres all over the world, and a quantum safe boundary protecting those data centres. The SKA Platform endpoint software then creates new keys with a new cryptographic technique, unlike anything seen before.
