Messaging
End-to-end encrypted instant messaging with OTR-grade key handling. Per-session keys, no message history retained, no metadata persisted.
The PSCE Platform
Secure communications without surrendering control.
Pryvate Secure Communications Engine (PSCE) provides encrypted messaging, voice, video and collaboration infrastructure for organisations that cannot outsource trust.
Deploy as a managed service, dedicated tenant, sovereign on-premise infrastructure, or embed secure communications directly into your own platform via SDK. Built for regulated organisations, government, healthcare, finance, legal services and technology providers where privacy, control and data sovereignty matter.

WHY PSCE · 01
Built for organisations that cannot outsource trust.
Most communications platforms ask you to trust a third party with your keys, your metadata, and your operational sovereignty. PSCE was designed for organisations that cannot make that trade — regulated industries, government agencies, defence integrators, and resellers who need to extend secure communications to their own clients without relinquishing control of the underlying infrastructure.
DESIGN PRINCIPLE · 02
Metadata minimisation by design.
PSCE is designed to minimise metadata generation and retention wherever operationally possible. Conversation keys are generated per-session on-device and never traverse Pryvate infrastructure. The architecture is built to avoid a central transcript to subpoena, a behavioural ledger to sell, or metadata exhaust to mine.
Read the technical briefPLATFORM CAPABILITIES · 03
Five capabilities. One platform.
Voice
Encrypted voice and conference calls over IP. ZRTP key exchange with post-quantum hybrid encryption. On and off-network calling with pooled DDI numbers.
Video
Encrypted video conferencing using a Selective Forwarding Unit architecture. The server routes encrypted media without decoding it — the conference itself cannot be wiretapped.
Sovereign Deployment
Deploy PSCE on Pryvate's network, on dedicated infrastructure, or fully within your own data centre. Three deployment models. One platform. Your governance, your jurisdiction.
SDK Integration
Embed PSCE-grade encryption into your existing SIP-based VoIP platform. SIP-compatible SDK with minimal UI footprint and full audit tooling. For telcos, OEMs, and enterprise platform teams.

BUSINESS OUTCOMES · 08
Outcomes, not just technology.
01
Reduce Regulatory Exposure
Prevent communications from escaping onto consumer apps. Keep sensitive conversations inside infrastructure you control.
02
Retain Corporate Control
Keep conversations, identities and governance inside your organisation. No third-party servers, no shared metadata, no platform lock-in.
03
Accelerate Deployment
Deploy secure communications in weeks instead of building from scratch. Use managed, dedicated tenant, on-premise, or SDK integration models.
COMPARISON · 09
Why not Teams, Zoom or WhatsApp?
Mainstream platforms are excellent collaboration tools — but they require you to surrender infrastructure, keys and metadata to a third party. PSCE exists for organisations that cannot make that trade.
