aconnic and Arqit join forces to present the first quantum-safe industrial OT security gateway firewall at Mobile World Congress 2026

aconnic AG (ISIN: DE000A0LBKW6), Munich, and Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW), London, a global leader in PQC migration tooling and quantum-safe encryption, announce a strategic cooperation to target the OT (Operating Technology) security market and present a quantum-safe industrial Hyper Security Gateway/Firewall at the Mobile World Congress (MWC) 2026 in Barcelona, Spain. The solution is based on the aconnic iGate 3000 firewall Gateway incorporating Arqit’s post-quantum cryptography technology.

By integrating Arqit’s technology into the aconnic iGate platform, aconnic enhances its iSphir OT Security Operating System with quantum-saferesistant key creation establishment and secure communication capabilities.

Quantum computing is rapidly transitioning from theoretical research to practical capability, so the introduction of a quantum-safe OT gateway marks a decisive step toward safeguarding critical infrastructure against next-generation cyber threats. As “harvest-now, decrypt-later” attack scenarios become increasingly realistic, aconnic addresses the urgent need for long-term cryptographic resilience in operational technology (OT) and mission-critical infrastructure environments. “Harvest-now, decrypt-later” refers to attacks in which attackers collect encrypted data in order to decrypt it later using more powerful computers, particularly quantum computers.

Operators of industrial networks, energy infrastructures, transportation systems, and defense-related environments are required to ensure that security architectures deployed today remain protected over extended operational lifecycles. The quantum-safe iGate gateway is designed to meet these future-proofing requirements.

The iGate secure field gateway is a core component of the iSphir OT security family and protects communication at the network edge. Combining industrial-grade hardware, secure boot mechanisms, protected key storage, hardware-based encryption, and integrated PQC functionality, the platform delivers layered protection for distributed OT deployments under harsh environmental conditions.

Developed in Europe and manufactured in Germany, the quantum-safe iGate reflects aconnic’s commitment to technological sovereignty, supply chain transparency, and long-term security lifecycle management. By combining pure European Engineering including aconnic’s hardware, software and German based Supply chain with Arqit’s advanced post-quantum cryptographic capabilities, the solution provides operators with a trusted and future-ready security architecture.

The joint presentation at MWC 2026 underlines the strategic cooperation between aconnic and Arqit and highlights the growing relevance of quantum-safe security in telecommunications and critical infrastructure networks. The aconnic AG will exhibit at MWC in Hall Congress Square, Booth CS50.
