CIS Exchange Mail Server is a decentralized email platform that provides end-to-end encryption without relying on third-party providers. The solution can be deployed on a dedicated obfuscated Virtual Private Server (D-VPS) or at customer-specified locations. The platform offers deployment behind a Virtual Dissimulated Encrypted Server (VDES) that obfuscates the real server's public IP address and points to a different IP/location. This implementation uses proprietary hardening techniques to create a decoy obfuscation environment that shields the actual mail server infrastructure from attackers. The mail server operates independently without dependencies on third-party providers or AWS backbone infrastructure. Customers maintain full control and oversight of the mail platform server, with deployment options including dedicated Virtual Private Servers, private rack servers, or physical servers within customer locations. The solution incorporates post-quantum cryptography (vdes-pqc) and provides anonymous, real-time email service with end-to-end encryption protocols. The decentralized architecture ensures that customers have complete control over their email infrastructure while maintaining privacy and security through obfuscation and encryption techniques.
