This white paper explores how Zero Trust Network Architecture (ZTNA) must evolve to remain effective in the face of quantum computing threats. While Zero Trust security models enforce continuous verification, least-privileged access, and identity-centric controls, they still rely on cryptographic foundations that are vulnerable to future quantum attacks. By integrating quantum-resistant VPNs such as QuantumGate’s QSphere VPN into a Zero Trust framework, organizations can secure data in transit, protect legacy and hybrid infrastructures, and meet regulatory requirements across sectors like healthcare, finance, government, and critical infrastructure. The result is a future-proof cybersecurity strategy that combines Zero Trust principles with post-quantum cryptography to defend against both current and emerging threats.
