Arc — DefenseTech Messenger The world's most advanced communications for contested environments.
Atlas builds Arc — a DefenseTech messenger for adversarial reality: surveillance, blackout, quantum decryption, device seizure.
Frontline Capabilities
Post-Quantum Cryptography — PQXDH with ML-KEM-1024 in production. Hardened against "harvest now, decrypt later."
End-to-End Encryption — Signal Protocol via libsignal-client (Rust FFI). Zero in-house crypto.
Read-or-Lose & IGF — World-first 24-hour key destruction. Unread messages are unrecoverable, even by us.
Anti-Impersonation — Cryptographic identity, Sealed Sender, and Arc IDs neutralize spoofing.
Offline Mesh — BLE peer-to-peer with no internet, no towers. Built for blackouts and conflict theaters.
Sovereign AI Characters — On-device and cloud personas across 20+ languages. B2B/B2G under client jurisdiction. Arc holds nothing.
Mission Surfaces Defense, government, medical, critical infrastructure, humanitarian response, and privacy-conscious civilians across EMEA and Asia.
Doctrine - Quantum-resistant from day one - Zero content visibility - Full E2EE on every tier - Engineered for the worst day on the network
DefenseTech is not a category. It is the discipline Arc was built under.
