Android — generally available
Distributable through your mobile device management platform or directly from us.
Product
An enterprise messenger you fully own.
Self-hosted server. Verified-only users. Built-in AI agent. Native Android and iOS clients. All connected only to your private infrastructure.
Pillar 01 · Sovereignty
Your data never leaves your perimeter
Run the server inside your own datacentre, private cloud or air-gapped intranet. We do not host, mirror, telemeter or back up your data — anywhere. Ever.
- On-premise server. Bare-metal, VM or container delivery. You choose the OS, the network and the storage.
- Works fully offline. Air-gap deployable. No outbound connectivity required at install, update or runtime.
- Offline license activation. Activation is code-based. The product never reaches our servers — for licensing or anything else.
- GDPR-grade by design. Data residency, processor independence and territorial control are baked into the architecture.
Pillar 02 · Verified users
A closed network of real, current employees
There is no public sign-up flow. Every user is provisioned by an administrator from your organisation, against an authoritative identity source.
- Admin-only onboarding. New accounts are created by your IT team, never by the user themselves.
- Tied to work identity. Same identity as Active Directory, SSO or your HRIS. One person, one verified profile.
- Same-day offboarding. When someone leaves, their access is revoked the same day — no orphans left in chats.
- No fraud, no fakes, no bots. Impersonation, drive-by registrations and bot phishing are eliminated at the source.
Pillar 03 · AI agent
Your conversation history, finally searchable
An integrated AI assistant indexes the messages and documents your users can already see — and answers natural-language questions about them.
- Semantic search. Find content by meaning, not just keywords. Across messages, threads and channels.
- Document-aware. Reads PDFs, Office files and images shared in chats. Surfaces the right artefact, not just the right chat.
- Permission-aware. Returns only content the requesting user is already authorised to see. Never more.
- On-prem inference option. Run the AI on your own GPU cluster — prompts and content remain entirely internal.
Native mobile clients — and they're free, forever
Day-to-day usability matters as much as architecture. The mobile clients are designed to feel as familiar as the consumer messengers your team is already using.
iOS — in development
General availability planned for 2026. Early access available for design partners.
Always free
Mobile clients carry no per-device cost. Ever. The licence covers users on the server, not endpoints.
How SP Secure Messenger stacks up
Cloud-first messengers optimise for ease of onboarding at the cost of control; consumer messengers optimise for reach at the cost of governance. SP Secure Messenger is built specifically for organisations that cannot accept either trade-off.
