Arqit Quantum Inc. (NASDAQ: ARQQ) announced November 11, 2025, the launch of its SKA Central Controller (SKA-CC), a software platform designed to simplify the deployment of quantum-safe network security for Managed Service Providers. This crypto-agile product generates dynamic symmetric keys for both endpoint authentication and encrypted VPN tunnels, eliminating reliance on traditional, potentially vulnerable, pre-shared keys or PKI infrastructures. SKA-CC supports quantum-safe cryptography across wireline, mobile, cloud, and AI environments—spanning OSI Layers 1-7—and enables Telcos and Defense providers to offer advanced, scalable security services while proactively addressing the evolving threat landscape posed by quantum computing.
Arqit Launches SKA Central Controller Platform
Arqit has launched SKA Central Controller (SKA-CC), a new software platform designed to simplify the deployment of quantum-safe network security for Managed Service Providers (MSPs). This platform addresses the looming threat of quantum computing by generating dynamic, symmetric keys for both endpoint authentication and encrypted VPN tunnels. Importantly, SKA-CC removes reliance on traditional, vulnerable methods like pre-shared keys or PKI infrastructures, offering a more agile and scalable solution for securing network communications.
SKA-CC’s versatility extends across multiple network layers, integrating with existing infrastructure from OSI Layer 1 (Optical) to Layer 7 (Applications). This includes compatibility with technologies like OTNsec, MACsec, IPsec, and TLS, allowing Telcos to offer quantum-safe services without disruptive “rip and replace” upgrades. Arqit highlights use cases spanning Secure Network-as-a-Service, Private 5G, IoT/OT security, and mobile VPNs, positioning the platform to address a broad range of security needs.
Recognized as an IDC Innovator in Post-Quantum Cryptography and winner of multiple industry awards, Arqit’s SKA-CC aims to future-proof network security. The platform’s ability to generate limitless volumes of keys with flexible refresh rates, combined with its lightweight agent design, enables strong encryption even on the smallest endpoint devices. This scalability and adaptability are critical as industries prepare for the evolving landscape of cybersecurity threats, particularly those posed by quantum computers.
SKA-CC Capabilities & Network Integration
Arqit’s newly launched SKA Central Controller (SKA-CC) simplifies deployment of quantum-safe network security for Managed Service Providers (MSPs). This software platform generates dynamic, symmetric keys for both endpoint authentication and encrypted VPN tunnels, eliminating reliance on traditional, vulnerable key management systems. SKA-CC integrates across multiple OSI layers – from physical (Layer 1) optical transport utilizing OTNsec, to application layers (Layers 4-7) – ensuring broad compatibility and scalable protection against evolving quantum computing threats.
SKA-CC’s architecture is designed for agility and efficiency. By supporting protocols like MACsec, IPsec, and TLS, it allows service providers to fortify existing infrastructure without costly “rip and replace” upgrades. The platform’s ability to deliver quantum-safe VPN services for mobile users, Private 5G networks, and IoT/OT environments highlights its versatility. This flexibility, combined with compliance with standards like NSA CSfC and RFC 8784, positions SKA-CC as a practical solution for immediate implementation.
Recognized as an IDC Innovator in Post-Quantum Cryptography and a winner of multiple industry awards, Arqit’s SKA-CC addresses a critical need for proactive security. The platform facilitates Secure Network-as-a-Service (NaaS) offerings, allowing Telcos to differentiate their services and unlock new revenue streams. By enabling multi-tenant key usage policies and automated management across virtualized environments, SKA-CC not only protects data but also streamlines operations for MSPs.
Securing Diverse Telecom Infrastructure Use Cases
Arqit’s newly launched SKA Central Controller (SKA-CC) addresses a critical need for future-proofed network security. The platform simplifies deployment of quantum-safe encryption across diverse telecom infrastructures – from virtual private networks (VPNs) utilizing IPsec and MACsec, to optical transport networks (OTNsec) at OSI Layer 1. Importantly, SKA-CC generates dynamic symmetric keys, eliminating reliance on vulnerable pre-shared keys or complex PKI systems. This approach delivers scalable, lightweight cryptography, preparing networks for the inevitable arrival of quantum computing threats.
SKA-CC’s versatility extends across multiple use cases, including secure Network-as-a-Service (NaaS), private 5G deployments, and IoT/OT security for critical infrastructure. By integrating quantum-safe keys directly into existing protocols—like mixing symmetric keys into IPsec VPNs—Arqit avoids disruptive “rip and replace” technology updates. This compatibility, coupled with support for standards like RFC 8784, allows telcos to rapidly enhance security services without significant infrastructure overhaul, streamlining deployment and reducing costs.
Recognized as an IDC Innovator and recipient of multiple industry awards, Arqit’s SKA-CC offers a practical solution to the growing threat of quantum computing. The platform’s ability to generate limitless key volumes with dynamic refresh rates and regulate device access aligns with Zero Trust Network Access principles. This scalable key management system, combined with compatibility with NSA CSfC standards, positions Arqit as a key player in delivering trusted, quantum-safe connectivity at a global scale for telecom operators and beyond.
