Arqit Quantum Inc. and 6WIND announced a strategic collaboration that will integrate Arqit’s NetworkSecure quantum‑safe encryption key‑generation technology with 6WIND’s Virtual Service Router (VSR) portfolio, enabling enterprises to deploy fully integrated, on‑device quantum‑safe IPsec VPNs across universal customer premises equipment and virtualised cloud infrastructure.
The partnership expands Arqit’s go‑to‑market footprint into the telecom and service‑provider space, creating a new channel for recurring revenue and accelerating adoption of its quantum‑safe encryption platform. By leveraging 6WIND’s global customer base and distribution network, Arqit can reach a broader set of customers that demand pre‑integrated, high‑availability solutions on low‑cost universal hardware and cloud infrastructure.
The quantum‑safe VPN market is projected to grow from $1.6 billion in 2025 to $4.93 billion in 2029. The collaboration positions both companies to capture this demand, with Arqit’s NetworkSecure providing the key‑generation engine and 6WIND’s VSR delivering the high‑performance, scalable networking stack required for enterprise‑grade VPNs.
The integration will allow on‑device, fully integrated quantum‑safe IPsec VPNs that maintain performance and scalability on existing hardware. Arqit’s symmetric key agreement platform will be embedded within 6WIND’s VSR, enabling customers to protect data in transit against current public‑key infrastructure vulnerabilities and future “harvest‑now, decrypt‑later” quantum attacks without sacrificing throughput or latency.
Arqit’s financial health remains challenging: revenue has declined 70.5% over the past three years, and the company reports operating and net losses. However, it maintains a strong liquidity position with a current ratio of 2.69 and a low debt‑to‑equity ratio of 0.03. 6WIND continues to expand its VSR portfolio with recent releases such as vPE, vCSR, vSecGW, and vCPE, and has announced a second‑generation VSR appliance and large‑scale deployments of its vHNA solution. Arqit has also secured a three‑year contract with an undisclosed global tier 1 telecommunications company and launched products such as Encryption Intelligence and the SKA Central Controller.
Scott Alexander, Arqit’s Chief Product Officer, said, “Our customers need highly available, pre‑integrated, quantum‑safe solutions deployable over flexible low‑cost universal hardware and cloud infrastructure. This is exactly what the integration between Arqit and 6WIND technology delivers.” The quote underscores the market demand for integrated quantum‑safe solutions and Arqit’s strategy to accelerate adoption.
The partnership is expected to accelerate the deployment of quantum‑safe VPNs in the telecom and enterprise markets, but Arqit’s ongoing financial challenges mean the collaboration will need to generate incremental revenue to offset its distress‑zone status. Nonetheless, the deal provides a strategic pathway to broaden its customer base and strengthen its position in a market that is becoming a regulatory requirement for many organizations.
