Company Overview

Arqit supplies a unique quantum-safe symmetric key agreement encryption platform which makes the communications links of any networked device, cloud machine or data at rest secure against current and future forms of attack – even from a quantum computer.

Compliant with NSA standards, Arqit’s product, SKA-Platform™, enables any device to download a lightweight software agent, which can create encryption keys locally in partnership with any number of other devices. The keys are computationally secure, optionally one-time use and operate over zero trust networks. SKA-Platform can create limitless volumes of keys with any group size and refresh rate and can regulate the secure entrance and exit of a device in a group.

The agent is lightweight and will thus run on the smallest of end point devices. The Product sits within a growing portfolio of granted patents. It also works in a standards compliant manner which does not oblige customers to make a disruptive rip and replace of their technology.

SKA-Platform is available as a Platform-as-a-Service - Arqit SKA(Paas)™ or as a sovereign private instance – Arqit SKA(PI)™.

Recognised for groundbreaking innovation at the Institution of Engineering and Technology awards in 2023, Arqit has also won the Innovation in Cyber Award at the National Cyber Awards and Cyber Security Software Company of the Year Award at the Cyber Security Awards. Arqit is ISO 27001 Standard certified.
