Security Features

Enterprise-Grade Encryption

Every message, every call, every file — quantum-encrypted end-to-end. No compromises, no backdoors, no metadata leaks.

Full E2EE by Default

Every message is end-to-end encrypted using MLS protocol. Not optional — it's on by default for all conversations, group chats, and file sharing.

MLS Protocol

Local-Only Key Storage

Encryption keys never leave the device. Not stored on servers, not in the cloud. Even with full server access, messages remain unreadable.

Zero Knowledge

Post-Quantum Encryption

Hybrid X25519 + Kyber768 key exchange protects against quantum computer attacks. AES-256-GCM with quantum-generated IVs. Your messages stay safe — even in a post-quantum world.

X25519 + Kyber768

Post-Compromise Security

If a session key is ever compromised, future and past messages remain secure through forward secrecy and automatic key ratcheting.

Forward Secrecy

Zero Trust Architecture

The server is designed to be untrusted. Even if the server is compromised, no message content or encryption keys can be extracted.

Server-Side Blind

Device Verification

Cross-device identity verification ensures you're always talking to the right person. Fleet device verification for enterprise MDM deployments.

Built on Proven Technology

Battle-tested open-source components with quantum-enhanced security layers.

MLS Protocol (RFC 9420)

Messaging Layer Security — the IETF standard for scalable E2EE group messaging. Tree-based key derivation for efficient group key management.

Proteus / MLS Hybrid

Post-Quantum Key Exchange

Hybrid X25519 + Kyber768 (NIST ML-KEM) key encapsulation inside MLS. Classical elliptic curve + lattice-based cryptography — immune to both classical and quantum attacks.

X25519 + Kyber768 Hybrid

Quantum Mesh Network

All inter-instance communication is encrypted via the QMesh/1.0 protocol. HMAC-SHA512 signatures prevent spoofing and replay attacks.

QMesh/1.0 Protocol

Self-Hosted Infrastructure

Deploy on your own servers. Full control over data, keys, and infrastructure. No third-party cloud dependencies. Your data stays yours.
