CIS Standalone VPN Server is a virtual private network solution that provides encrypted connections for data transmission over the Internet. The product supports multiple VPN protocols including OpenVPN, IKEv2, PSK, and WireGuard. The solution implements Post-Quantum Cryptography using ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism) at NIST Security Level 5, which uses an IND-CCA2 secure key encapsulation mechanism approach. This cryptographic implementation is designed to resist attacks from large-scale quantum computers while passing classical cryptanalysis. The VPN server infrastructure operates without logging user information and does not associate individual identities with account and billing information. The system includes proprietary VPN client applications for Windows, Linux, and Android operating systems. The cryptographic implementation includes protections against various attack vectors including static timing analysis, fault attacks, simple power analysis, cold-boot attacks, template attacks, and electromagnetic attacks. The solution is designed to protect data in transit across Internet connections. The product is positioned for users requiring anonymous research capabilities and secure collaboration across service platforms, with security and anonymity as primary design objectives.
