Arqit

What Arqit does

Arqit Quantum Inc. is a publicly traded (Nasdaq: ARQQ, ARQQW), Cayman Islands-incorporated quantum-safe encryption company headquartered in London. Founded in 2016-2017 (operating subsidiary Arqit Limited incorporated in England) and brought public via September 2021 SPAC merger with Centricus Acquisition Corp., Arqit builds a software-based symmetric key agreement (SKA) encryption platform. The proprietary SKA-Platform deploys lightweight software agents that create quantum-safe encryption keys locally between any number of networked devices, operates over zero trust networks, and is positioned as the only software-based, globally scalable symmetric key agreement solution with security proofs independently validated by the GCHQ Accredited Centre of Excellence at the University of Surrey and PA Consulting.

The product portfolio comprises three core offerings: SKA-Platform (with SKA Edge Controller and SKA Central Controller deployment variants for hardware/cloud and virtualized data centers, available as SKA-PaaS or sovereign SKA-PI), NetworkSecure (a lightweight VPN encryption application integrating with OEM firewalls, routers, and edge platforms from Fortinet, Juniper, Cisco, Intel, 6WIND, RAD, aconnic, and StrongSwan), and Encryption Intelligence (a SaaS cryptographic discovery and inventory tool acquired from Ampliphae in May 2025 and selected by the UK NCSC for its PQC Pilot). The platform is compliant with NSA CSfC, NSA Symmetric Key Management Requirements Annex 3.0, FIPS 140-3, ISO 27001, AES-256, IPsec, and TLS, and is backed by 28 granted and 17 pending patents across major jurisdictions.

Arqit operates primarily through a B-2-B-2-B channel model, embedding its encryption into OEM vendor products, tier-one telecom network operators (Sparkle, RSG/Fabric Networks, Colt), and defense/IT system integrators. Revenue streams include perpetual software licenses, multi-year SaaS subscriptions, professional services, and maintenance/support. FY2025 revenue was $530,000 across seven contracts, with H1 FY2026 reaching $623,000 (up 829% YoY) on 11 active contracts and management guiding to $2.48M for FY2026 and $7.8M for FY2027. Reported active customers include Sparkle (telecom/NaaS), RSG/Fabric (telecom/natural resources), the US Department of War (via IT vendor partner), Middle East government agencies (largest license contract, multi-year via IT vendor), and A&K Travel Group (via Colt). Cash position was $35.9M as of May 2026 with ~14 months of runway against $2.6M average monthly burn; securities class action litigation was resolved with a court-approved $7M settlement in June 2026.

Core offering

Arqit develops and sells a quantum-safe symmetric key agreement encryption platform that enables networked devices to generate encryption keys locally via lightweight software agents, securing communications links, cloud machines, and data at rest against current and future quantum threats. Core products include SKA-Platform, NetworkSecure, and Encryption Intelligence, offered as perpetual licenses or Platform-as-a-Service to telecom operators, government, defense, and enterprise customers.

Product overview

Arqit Quantum offers a quantum-safe encryption platform with three core products: SKA-Platform (symmetric key agreement encryption), NetworkSecure (VPN encryption application), and Encryption Intelligence (cryptographic discovery tool). SKA-Platform operates through lightweight software agents deployed on endpoints, with two deployment configurations: SKA Edge Controller (SKA-EC) for simple hardware/cloud deployment and SKA Central Controller (SKA-CC) for virtualized data center and cloud environments serving thousands of endpoints. SKA-Platform is available as Platform-as-a-Service (Arqit SKA PaaS) or sovereign private instance (Arqit SKA PI). NetworkSecure is a standalone VPN encryption application that integrates with major OEM platforms including Fortinet, Juniper, and Cisco. Encryption Intelligence provides cryptographic discovery and risk prioritization to help organizations migrate to post-quantum cryptography. The company acquired Ampliphae's product portfolio to enhance encryption risk advisory capabilities.
