Arqit NetworkSecure is a software-based encryption layer that enhances existing VPN and IPsec environments to protect data-in-transit from both current threats and future quantum-enabled attacks. It integrates seamlessly with existing infrastructure, enabling agencies to strengthen cryptographic security, meet compliance requirements and transition to post-quantum protection without costly replacements. Through centralized key orchestration and real-time quantum-safe key generation, NetworkSecure reduces operational complexity while delivering secure, high-performance protection for critical data flows.
