Its software is intended for use by organizations seeking to secure networks, devices and information. The company’s platform generates and manages symmetric encryption keys and is designed to integrate with existing communications and security systems. Arqit offers software for protecting data and network connections, rather than relying on quantum computers to perform encryption. Arqit previously pursued a satellite-based approach to distributing encryption keys, but later shifted toward a software-focused model. The company became publicly traded on Nasdaq in 2021 through a business combination with a special purpose acquisition company.AI Generated. May Contain Errors.
