Arqit launches SKA Central Controller to simplify quantum-safe network deployments for Managed Service Providers

LONDON, Nov. 11, 2025 (GLOBE NEWSWIRE) -- Arqit Quantum Inc. (NASDAQ: ARQQ, “Arqit”), a global leader in quantum-safe encryption, today announced the launch of SKA Central Controller (SKA-CC), an innovative software platform that future-proofs network security against current and post-quantum threats.

SKA-CC is a crypto-agile, low-footprint product that enables Telco and Defense Managed Service Providers to deliver quantum-safe network services without the cost and complexity of traditional key management. The platform generates dynamic symmetric keys for both endpoint authentication and encrypted VPN tunnels, removing reliance on long-lived pre-shared keys or PKI-based infrastructures.

SKA-CC ensures that data moving over virtual private networks across wireline, mobile, cloud and AI-enabled environments is protected by strong, lightweight and scalable cryptography that is quantum-safe by design.

Enabling new high-growth security services for telecom operators

SKA-CC supports a wide range of telecom and communication infrastructure use cases, allowing service providers to deploy advance security capabilities for existing and new offerings, including:

• Secure Network-as-a-Service (NaaS): Quantum-safe, multi-layer VPN services with multi-tenant key usage policy controls. Securing use cases for virtual network functions, Universal CPE and Virtual Private Cloud interconnections for highly automated management and orchestration (MANO) environments.
• Optical (OSI Layer 1): Integrates quantum-safe symmetric keys with OEM transport equipment that utilises OTNsec.
• Carrier Ethernet (OSI Layer 2): Enables high-throughput, quantum-safe MACsec point-to-point links.
• Internet Protocol (OSI Layer 3): Mixing in symmetric keys to IPsec VPNs, making them quantum-safe.
• Application Programming Interfaces (OSI Layer 4-7): Fortifying TLS-based APIs to a quantum-safe standard.
• Mobile VPNs: Delivers post-quantum secure VPN services for mobile and remote users.
• Private 5G: Secures infrastructure connectivity between radio base stations and the core network.
• IoT / OT security: Protects communication between edge gateways, IoT hubs and cloud services, ideal for energy, oil and gas and critical infrastructure applications.

By integrating SKA-CC, Telcos can differentiate their services and build new revenue streams while meeting the rising demand for post-quantum security across connected industries.

“Quantum computing will change the threat landscape,” said Scott Alexander, Chief Product Officer at Arqit. “SKA-CC gives our partners a practical way to secure their networks today, and stay ahead of tomorrow’s risks. It extends Arqit’s mission to make strong encryption simple and scalable, enabling the telecom ecosystem to deliver trusted, quantum-safe connectivity at global scale.”

Notes to Editors

About Arqit

Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW) supplies a unique encryption software service which makes the communications links of any networked device, cloud machine secure against both current and future forms of attack on encryption – even from a quantum computer. Compatible with NSA CSfC Components and meeting the demands of NSA CSfC Symmetric Key Management Requirements Annexe 1.2. and RFC 8784, Arqit’s Symmetric Key Agreement Platform uses a lightweight software agent that allows end point devices to create encryption keys locally in partnership with any number of other devices. The keys are computationally secure and facilitate Zero Trust Network Access. It can create limitless volumes of keys with any group size and refresh rate and can regulate the secure entrance and exit of a device in a group. The agent is lightweight and will thus run on the smallest of end point devices. The product sits within a growing portfolio of granted patents. It also works in a standards compliant manner which does not oblige customers to make a disruptive rip and replace of their technology. In September 2024, Arqit was named as an IDC Innovator for Post-Quantum Cryptography, 2024. Arqit is winner of two GSMA Global Mobile Awards, The Best Mobile Security Solution and The CTO Choice Award for Outstanding Mobile Technology, at Mobile World Congress 2024, recognised for groundbreaking innovation at the 2023 Institution of Engineering and Technology Awards and winner of the National Cyber Awards’ Cyber Defense Product of the Year 2024 and Innovation in Cyber Award 2022, as well as the Cyber Security Awards’ Cyber Security Software Company of the Year Award 2022. Arqit is ISO 27001 Standard certified. www.arqitgroup.com
