Chattic

Chattic is a high-stakes communications and operations platform — a secure command centre rather than a chat app — for organisations that cannot absorb a data leak, a compromised network, or a missed critical alert.

At its centre is the Fortress security engine: a hybrid post-quantum cryptographic core combining classical X25519 with NIST-standardised ML-KEM-1024 (FIPS 203). All messaging, calls, and stored files are end-to-end encrypted with per-message forward secrecy, defeating "Harvest Now, Decrypt Later" attacks in which adversaries capture encrypted traffic today to decrypt once quantum computers mature.

The communication suite covers private and group messaging across ten message types — text, images, HD video, audio notes, documents, links, replies, reactions, scheduled, and forwarded — alongside PQC-encrypted VoIP voice and video calls and webinar broadcasting for up to eight hosts with unlimited viewers. Stealth messaging lets users in high-risk settings conceal sensitive text behind ordinary-looking dummy messages, without the obvious hidden-message markers that draw attention in mass-market apps. The Vault — Chattic's evidence locker — stores confidential files under AES-256 with post-quantum-protected keys, and a global kill switch can cryptographically shred any file across every device and server it touches.

Chattic deploys two ways. The Global SaaS edition is a cloud-managed service that feels like a familiar messaging app while carrying enterprise-grade security and liability controls. The Sovereign edition is a fully air-gapped, on-premise installation for military, government, and secretive organisations — operating with no reliance on external cloud providers and engineered for controlled or disconnected environments.
