Why Choose Guardyn?
Military-grade cryptography meets enterprise-grade infrastructure. Built by security engineers for the privacy-conscious era.
Post-Quantum Cryptography
ML-KEM (Kyber) + X25519 hybrid key exchange. Double Ratchet with AES-256-GCM. OpenMLS for groups. PADMÉ padding for traffic analysis protection. Future-proof against quantum computers.
Audit-Ready Transparency
Reproducible builds with Nix, SBOM generation, artifact signing with Cosign, TLA+ formal proofs, and independent security audits (Cure53, Symbolic Software).
Enterprise Infrastructure
Rust backend, TiKV for distributed transactions, ScyllaDB for high-throughput storage, Redpanda (Kafka-compatible) for event streaming. Docker Compose dev, Kubernetes prod.
High Performance
Message delivery <500ms, call setup <2s, voice latency <150ms, 1080p video at 30fps, 1000+ messages/sec throughput.
Platform-Optimized Clients
Flutter for iOS & Android — touch-first, native feel.
Tauri + SolidJS for desktop — native menus, system tray, screen sharing.
Unified guardyn-crypto Rust core via FFI.
E2EE Voice & Video
WebRTC with SFrame encryption, Opus codec for audio, VP9/AV1 for video. First platform with E2EE live broadcasting (<2s latency).
OpenMLS Group Chat
IETF-standard Messaging Layer Security for groups up to 1000 members. Cryptographic guarantees for group confidentiality and integrity.
Hardware-Backed Keys
Secure Enclave (iOS/macOS), AndroidKeyStore (Android), TPM 2.0 (Windows/Linux). Identity keys protected by secure hardware — never extractable.
Unified Crypto Core
Single guardyn-crypto Rust library for all platforms.
One security audit, zero implementation drift between iOS/Android/Desktop.
Self-Hosted Option
