    In today’s interconnected world, Virtual Private Networks (VPNs) are essential for secure communication and data protection. However, with the rise of quantum computing, the security landscape is rapidly changing, necessitating advanced measures to secure VPN infrastructures. By integrating post-quantum hybrid cryptography into VPNs, organizations can fortify their security measures and safeguard sensitive information against the threats posed by quantum computing. For that we propose a hybrid cryptography approach to integrate post-quantum security into Virtual Private Network protocols. Our approach utilizes the Kyber key encapsulation mechanism (KEM) in combination with the WireGuard VPN protocol to encrypt the public key before exchanging it with the server. We conducted a security analysis of our proposed approach and compared it to classical VPN protocols like OpenVPN and WireGuard without post-quantum security. Our findings demonstrate that the proposed hybrid approach provides a higher level of security against attacks by quantum computers. the performance evaluation of our approach demonstrates that it performs comparably to the original WireGuard protocol in terms of computational overhead and latency while outperforming OpenVPN in terms of key generation and encryption speed
