Arqit and 6WIND Forge Quantum-Safe Shield for Telco Networks

LONDON – February 19, 2026 – In a significant move to counter the looming threat of quantum computing, encryption specialist Arqit and networking software leader 6WIND today announced a strategic collaboration to deliver quantum-safe virtual private networking (VPN) services. The partnership integrates Arqit’s advanced encryption technology directly into 6WIND’s high-performance virtual routers, creating a ready-to-deploy solution for telecommunications providers aiming to secure their customers' most sensitive data.

This joint offering addresses a growing urgency within the cybersecurity community to defend against future attacks capable of shattering today’s encryption standards. By providing a scalable, software-based solution, the two companies aim to accelerate the adoption of post-quantum cryptography (PQC) across enterprise and government sectors.

The 'Harvest Now, Decrypt Later' Imperative

For years, the quantum threat has been discussed as a distant, almost theoretical problem. However, a more immediate and insidious danger known as “harvest now, decrypt later” (HNDL) has shifted the timeline dramatically. This strategy involves adversaries capturing and storing vast amounts of encrypted data today, with the intention of decrypting it years from now when a sufficiently powerful quantum computer becomes available.

Data with long-term value—such as national security secrets, intellectual property, financial records, and personal health information—is particularly vulnerable. The security of this information relies on public-key infrastructure (PKI), the cryptographic foundation of the internet, which experts widely agree will be rendered obsolete by quantum machines.

This looming “Q-Day” has ignited a race to develop and deploy new cryptographic standards. The global PQC market, valued at approximately $2.3 billion in 2026, is projected to surge to nearly $30 billion by 2034, according to industry analysts. This explosive growth reflects a market awakening to the reality that preparations must begin immediately. While governments and critical infrastructure operators are leading the charge, many enterprises remain in the early planning stages, often hindered by a lack of in-house expertise and concerns over integration complexity. The Arqit-6WIND collaboration is positioned to address this gap by lowering the barrier to entry.

A New Standard in Cyber Defense

At the heart of the new partnership is the integration of Arqit’s NetworkSecure™ technology with 6WIND’s Virtual Service Router (VSR) product portfolio. This creates a fully integrated, on-device quantum-safe IPsec solution that can be deployed on universal customer premises equipment (uCPE) and in the cloud.

Unlike traditional PKI, which relies on public and private key pairs, Arqit's technology is built on a Symmetric Key Agreement (SKA) platform. This software-based approach allows two authenticated endpoints to create unique, quantum-safe encryption keys on demand, without transmitting them across the network. The keys are computationally secure against both classical and quantum attacks, providing a provably secure foundation for data in transit.

By embedding this capability within 6WIND’s high-performance networking software, the solution offers both next-generation security and the efficiency required by modern networks.

“Our customers need highly available, pre-integrated, quantum-safe solutions deployable over flexible low-cost universal hardware and cloud infrastructure,” said Scott Alexander, Chief Product Officer at Arqit. “This is exactly what the integration between Arqit and 6WIND technology delivers.”

Karim Mchirki, VP Product Management at 6WIND, echoed this sentiment, emphasizing the blend of security and performance. “By combining 6WIND’s high-performance, software-defined networking solutions with Arqit’s proven quantum-safe key generation technology, we enable organizations to deploy next-generation secure connectivity services at scale,” he stated. “This collaboration addresses emerging quantum threats while preserving the performance, agility, and efficiency required by modern networks.”

Empowering Telcos as Quantum Guardians

The collaboration specifically targets telecommunication service providers, positioning them as frontline defenders in the quantum era. By offering a pre-packaged, quantum-safe VPN service, telcos can provide a critical value-added security layer to their enterprise and B2B customers, protecting everything from site-to-site connections to complex hub-and-spoke architectures.

For many enterprises, the path to PQC adoption is fraught with challenges, including high costs, performance overhead, and the daunting task of integrating new algorithms into legacy systems. An integrated solution from a trusted communications service provider simplifies this transition immensely. It abstracts away the complexity, allowing businesses to secure their data flows without undertaking a massive internal cryptographic overhaul.

This model allows telcos to not only secure their own infrastructure but also to create a significant competitive differentiator in a crowded marketplace. As regulatory pressure mounts and customer awareness of quantum risks grows, the ability to offer “quantum-ready” services will become a key selling point for providers catering to security-conscious industries.

Navigating a Competitive and Evolving Landscape

Arqit and 6WIND are entering a dynamic and increasingly competitive field. Other major players are also moving to commercialize quantum-safe services. In Canada, TELUS has launched a quantum-safe VPN service using technology from Palo Alto Networks. Meanwhile, global connectivity provider Sparkle is offering a similar service built on a Network-as-a-Service model—notably, also in collaboration with Arqit.

This highlights Arqit’s strategy of positioning its NetworkSecure™ technology as a foundational component that can be integrated by various partners across the telecommunications ecosystem. Its software-only, standards-compliant approach, which aligns with guidance from bodies like the U.S. National Institute of Standards and Technology (NIST), makes it an attractive option for vendors looking to quickly upgrade their portfolios.

The partnership with 6WIND, however, is distinct in its focus on integrating directly with a high-performance virtual router, promising a seamless blend of security and speed for software-defined networks. As the industry continues its march toward a post-quantum future, such strategic alliances between cryptographic innovators and established network infrastructure providers will be crucial in building a resilient and secure digital world.
