Secure Xchange Mail is Entropya's decentralized, end-to-end encrypted email server, deployable on infrastructure you fully control: a private rack, a hardened on-premises server, or a dedicated Virtual Private Server. No hyperscaler backbones, no third-party listening points.
Connections are secured with FIPS 203-compliant post-quantum cryptography (ML-KEM) against harvest-now-decrypt-later interception. An optional Virtual Dissimulated Encrypted Server (VDES) gateway conceals the server's real IP and shields it from scanning and address-based attacks.
Built for corporations, legal and financial firms, healthcare providers, and government and defence operators that need email confidentiality at rest, in motion, and through the quantum transition.
