NOVARYX Secure Messaging Platform
White-label end-to-end encrypted messenger for official internal comms. On-prem or Zeour-cloud, off-grid mesh, compliant archiving. Book a guided demo.
Comprehensive NOVARYX Messenger
Zeour NOVARYX — a white-label, end-to-end encrypted messaging platform for official internal communications. Engineered per engagement to each organisation's exact workflows: sovereign on-premises or Zeour-cloud deployment, org-directory access control, compliant message archiving held by your organisation, encrypted media and calls, and an off-grid field mode that keeps teams messaging over multi-hop mesh when there is no network. In production at Zeour Ltd for our own official communications. Editions are scoped to the organisation — a 30-person firm on Zeour-cloud is as valid a deployment as a 5,000-seat sovereign estate.
Understanding NOVARYX — Secure Messaging Engineered to Your Organisation
NOVARYX is a secure communications platform, not a seat subscription: an end-to-end encrypted messaging core, an organisational control plane (directory, policy, archive, administration), and an off-grid field mode — assembled into a branded edition engineered to each customer's workflows, platforms, and regulatory obligations. The backend runs inside your perimeter (or on Zeour-cloud where preferred), stores ciphertext only, and is governed entirely by your organisation. Engineered multilingual — full RTL as a production baseline, any locale per engagement. The reference implementation carries Zeour Ltd's own official communications in daily production.
Key Functionalities
Encrypted Messaging Core
End-to-end encrypted 1:1 and group messaging built on open, audited cryptographic standards — AES-256-GCM content encryption, modern key agreement with a post-quantum-ready design, MLS-aligned (RFC 9420) group encryption, and per-sender message signing so a group member cannot impersonate another.
Groups, Channels & Broadcast
Directory-governed groups (department, site, shift, project), open rooms where policy allows, and one-to-many broadcast channels with read tracking for announcements — each with role-based membership and admin controls.
Encrypted Media & Voice Notes
Images, documents, and voice notes sealed with per-message content keys; ciphertext blobs stored on your infrastructure; metadata stripped from shared media on-device before it ever leaves the sender.
Encrypted Voice & Video Calls
Standards-based WebRTC calling with encrypted signalling over the messaging envelope and self-hosted relay infrastructure inside your perimeter — no third-party calling service in the path.
Message Lifecycle Controls
Edit and delete-for-everyone windows, disappearing messages with policy-set timers, view-once media, starred messages, reply threading, and forward limits that curb uncontrolled redistribution — each configurable per deployment policy.
Encrypted On-Device Storage & Search
The local message store and its search index are encrypted at rest on every device; search runs entirely on-device so plaintext never reaches a server; deletion and disappearing-message purges zeroize the index.
Private Notifications
Push payloads carry ciphertext only; the device decrypts locally to show a preview, and degrades to a generic notification for protected content — message content never transits notification infrastructure in plaintext.
Off-Grid Field Mode
Multi-hop mesh messaging over short-range radio with store-and-forward relay, hop budgets, and deduplication — encrypted messages hop device-to-device where there is no network, then reconcile with the platform when connectivity returns.
Org Directory & Policy Engine
Who can message whom, who can create groups, which features are enabled for which roles, receipt and presence behaviour, retention windows — expressed as organisational policy against the directory, not left to individual users.
Compliance Archive & Legal Hold
An organisation-held archive engineered to your regulatory framework: retention schedules, supervisory review, legal hold, export for discovery, and a complete audit trail of archive access itself.
Admin Console
User and device lifecycle, policy management, remote wipe of the app container, usage and adoption reporting, broadcast administration, and an append-only audit log of every administrative action.
Identity & Provisioning
SAML 2.0 / OIDC single sign-on against your identity provider; SCIM keeps the directory synchronised with HR reality — joiners, movers, and leavers handled automatically, sessions revoked on offboarding.
White-Label & Multi-Platform
Your name, icon, colours, and store or MDM listing across the platform matrix scoped for your workforce — mobile, tablet, desktop, and web per engagement, distributed through your device-management tooling.
Engineered Multilingual
Full right-to-left support as a production baseline with locale-aware formatting throughout; additional locales are configuration-level additions per engagement, not re-engineering.
Software Components
Client Applications
Branded Mobile Apps
Your organisation's messenger for phones and tablets — encrypted local store, on-device search, private notifications, MDM-distributed under your identity.
Desktop & Web Clients
Per-engagement desktop and browser clients for office-based staff, sharing the same encrypted session model and organisational policy as mobile.
Field-Mode Module
The off-grid radio and relay layer inside the client — mesh discovery, store-and-forward queueing, and automatic reconciliation when the network returns.
Messaging Backend (Your Perimeter)
Delivery Service
Relays and queues ciphertext envelopes with durable store-and-forward semantics, backlog replay on reconnect, and consume-after-delivery cleanup so the server holds no more than it must.
Encrypted Media Store
Holds sealed media blobs only — content keys travel inside the encrypted message envelope, never stored server-side.
PostgreSQL-Based Data Layer
A proven relational core for directory, policy, queue, and archive state — operable, backupable, and auditable by your own DBA team.
Enterprise Control Plane
Org Directory Service
The authoritative model of people, departments, sites, roles, and devices — the object every messaging and archive policy binds to.
Policy Engine
Evaluates messaging permissions, feature availability, retention rules, and field-mode authorisation per user, group, and context.
Compliance Archive
Organisation-governed retention, supervisory review, legal hold, and export — engineered to the regulatory framework mapped in discovery.
Admin Console & Audit Log
The operational surface for IT and compliance teams, with every administrative action recorded append-only.
Identity & Integration
SSO Bridge (SAML 2.0 / OIDC)
Authentication delegated to your identity provider; no parallel password estate.
SCIM Provisioning Endpoint
Directory lifecycle synchronised from your HR / IdP source of truth.
REST API + Webhooks
Broadcast publishing, directory operations, archive export, and event forwarding for integration with ERP, CRM, ITSM, and SIEM platforms.
Hardware Components
On-Premises Deployment Options
Branch-Class Server Appliance
The messaging backend pre-installed and hardened on Zeour's industrial branch-class server hardware — one vendor for software, hardware, deployment, and AMC. See the hardware catalogue on the queue-management page.
Managed Device Fleet Provisioning
Corporate device fleets prepared for field deployments — MDM enrolment, app distribution, and radio configuration for sites that run off-grid field mode.
Self-Hosted Call Relay Node
Media relay infrastructure for encrypted voice and video calling deployed inside your perimeter, sized to concurrent-call requirements during discovery.
NOVARYX Architecture — Sovereign by Design
Three tiers, one principle: message content exists in plaintext only on managed end-user devices. The backend — deployable on your servers, on a Zeour appliance, or on Zeour-cloud — relays and stores ciphertext, while the control plane gives your organisation the governance consumer apps cannot: directory, policy, archive, and audit. Standards end to end: AES-256-GCM, MLS-aligned group encryption (RFC 9420), TLS 1.3 transport, SAML 2.0 / OIDC / SCIM identity, WebRTC calling.

- Offline outbox — messages queued locally auto-send when connectivity returns
- Off-grid mesh: multi-hop store-and-forward with hop budgets and deduplication
- Cross-mode reconciliation — field-mode traffic syncs to the platform when back in coverage
- Delivery and read receipts advance end-to-end, policy permitting
NOVARYX vs the Alternatives Buyers Actually Consider
Three realistic options for official internal communications — a consumer app your staff already use, a generic cloud chat SaaS, or a platform engineered to your organisation. The right choice depends on how regulated, how sovereignty-sensitive, and how field-operational your organisation is.
Consumer messaging apps
Best for: Personal life — not official business
- Familiar UX and effortless adoption
- End-to-end encryption for personal chats
- No organisational archive, policy, or admin control
- Accounts bound to personal identities and devices
- Data and backups on vendor-chosen consumer clouds
- No off-grid capability; no workflow fit; no accountability
Generic cloud chat SaaS
Best for: Office collaboration inside one vendor's cloud
- Channels, threads, and app integrations for desk workers
- Per-user-per-month subscription that compounds forever
- Vendor-hosted: residency and retention on the vendor's terms
- Limited or partial end-to-end encryption in practice
- No white-label identity; no off-grid mode
- Field and frontline staff typically left out of licensing
NOVARYX engineered platform
Best for: Regulated, sovereignty-sensitive, and field-operational organisations
- End-to-end encrypted messaging with an org-held compliance archive
- Sovereign on-premises, appliance, or Zeour-cloud deployment
- White-label identity and per-engagement feature scope
- Directory + SSO + SCIM organisational lifecycle
- Off-grid multi-hop mesh field mode
- One-time licence + AMC — owned, not rented

Inside a NOVARYX Deployment
The surfaces of an engineered edition — messaging, governance, field mode, and compliance.
Why Consumer Messaging Apps Fail Official Communications
Staff will always use the best channel available. If the best channel is a personal consumer app, official business ends up ungoverned, unarchived, and outside your perimeter.
Official business on personal apps
Operational decisions, customer data, and incident coordination flow through personal accounts on consumer apps — outside organisational control, invisible to compliance, and gone when the employee leaves.
A branded official channel
Your organisation's own messenger — familiar consumer-grade UX under your name, governed by your directory and policy, adopted because it is genuinely the best channel available to staff.
No archive, no audit trail
Regulators in banking and government expect official communications to be retained and reviewable. Consumer apps offer neither — and firms worldwide have paid substantial fines for exactly this gap.
An org-held compliant archive
Retention, supervisory review, and legal hold engineered to your regulatory framework, inside your perimeter, with archive access itself audited.
Data on consumer clouds you don't govern
Message content, metadata, and backups live on infrastructure chosen by the app vendor, in jurisdictions chosen by the vendor — the opposite of data residency and sovereignty policy.
Sovereign deployment
The full backend on your infrastructure — on-premises by default, with an appliance option on Zeour server hardware — or Zeour-cloud where managed operations are preferred.
No organisational lifecycle
Leavers keep group memberships. Accounts bind to personal phone numbers. There is no provisioning, no policy, no remote wipe, no admin console — because those were never the product's job.
Directory-driven lifecycle
SSO + SCIM tie messaging to HR reality: joiners provisioned automatically, leavers deprovisioned instantly, devices wiped remotely, every admin action logged.
Dead zones stop operations
Consumer messengers assume the internet. Remote sites, offshore platforms, basements, tunnels, and disaster scenarios have none — and operations there go silent or fall back to unlogged radio.
Off-grid field mode
Encrypted multi-hop mesh messaging keeps teams coordinating with zero infrastructure, then reconciles with the platform when connectivity returns.
One-size features, zero workflow fit
A generic app cannot express your org structure, your approval flows, your terminology, or your regulator's retention schedule. Workarounds accumulate; governance erodes.
Engineered per engagement
Your workflows, platforms, locales, and compliance obligations are mapped in discovery and built into your edition — the platform fits the organisation, never the reverse.

How NOVARYX Messenger Works
A simple, streamlined process to get you up and running quickly.
Scope & Discovery (Fixed-Fee)
We map your communication workflows, compliance obligations (which regulator, what retention, who audits), platform matrix, device estate, integration list, and deployment model — sovereign on-premises or Zeour-cloud. Output: a fixed-price build scope with a milestone plan.
Workflow & Policy Design
Org-directory model (who can message whom), messaging policy (receipts, disappearing windows, forwarding limits), retention and legal-hold rules, admin roles, archive access governance, and your white-label brand direction — designed with your compliance and IT teams before anything is built.
Build, Brand & Integrate
Your edition is built to the approved scope: name, icon, colours, feature set, locales. Identity is wired to your SSO (SAML 2.0 / OIDC) with SCIM provisioning; REST + webhook integrations connect HR, ERP, CRM, or ITSM systems where scoped.
Deploy & Pilot
Deployment lands on your infrastructure (or Zeour-cloud), distributed to managed devices through your MDM. A pilot group runs real traffic; where field mode is in scope, off-grid mesh trials run at a representative site before rollout.
Roll Out, Train & Operate
Staged rollout across departments and sites, admin and end-user training, and a documented handover. The Annual Maintenance Contract covers updates, security patches, and operational support — with operator self-sufficiency as the exit posture.
