Arqit is an early-stage cybersecurity software company focused on quantum-safe encryption. The core problem Arqit addresses is that most internet security today relies on asymmetric (public key) cryptography, which is expected to be vulnerable to quantum computers once they mature. Arqit's solution replaces this with symmetric key cryptography, which is not mathematically based and therefore not vulnerable to quantum attack. Arqit's main products are SKA-Platform, a software agent deployed on endpoints to dynamically create and manage quantum-safe encryption keys; NetworkSecure, which bolsters VPN security against current and future quantum-enabled attacks; and Encryption Intelligence, an analytics product that maps an organization's existing encryption, identifies weaknesses, and serves as a sales funnel for Arqit's protection products. Arqit sells primarily through a B2B2B channel model, licensing its technology to IT vendors, network equipment providers, and system integrators, who bundle or resell it to end customers. Primary customers include governments, militaries, telecom operators, and large enterprises. Arqit generates revenue from recurring software licenses — structured to grow as channel partners add end customers — plus professional services. The company is at a very early commercial stage, with a small contract base and substantial operating losses funded by cash on hand.
