Sovereign Modern Workplace

Collaboration without dependencies.

Public administration, critical infrastructure or businesses with strict compliance requirements: more and more organisations want to regain control over their data, their tools and their costs. A sovereign modern workplace built on open source delivers exactly that – email, files, office, chat, video conferencing, projects and knowledge from a single platform, operated wherever you want it.

With openDesk – the workplace suite for the public sector coordinated by the German Centre for Digital Sovereignty (ZenDiS) – an integrated portal solution now exists, built from proven open-source components such as Nextcloud, Collabora, Open-Xchange, Element, Jitsi, OpenProject and XWiki. dotmec supports you from strategy through pilot and migration to operations – including coexistence with Microsoft 365 where that is the more economical path.

Best of all: you do not have to choose between the two worlds. As a Microsoft partner with deep Microsoft 365 expertise, we know both sides from day-to-day project work – which is exactly why we can deliver coexistence and migration strategies with a holistic strategic focus: sovereign where data sovereignty matters, pragmatic where it makes economic sense – always guided by a clear target picture rather than ideology.

Services

Our services for your sovereign workplace.

From the portal platform to individual components – bookable individually or as a complete package.

  • openDesk adoption

    Consulting, design and rollout of the public sector's integrated portal solution – from target picture and operating model to productive use.

  • Nextcloud – files & collaboration

    A sovereign file cloud with sharing, sync and workflows – the heart of your collaboration, on-premises or with an EU hosting provider.

  • Collabora Office – documents in the browser

    Edit texts, spreadsheets and presentations together in the browser – compatible with common office formats, without data leakage.

  • Element & Matrix – sovereign chat

    Modern team chat on the open Matrix protocol: federated, end-to-end encryptable and under your control.

  • Jitsi – video conferencing

    Browser-based video meetings without mandatory clients and without third-country transfers – on your infrastructure or as a hosted service.

  • OpenProject – projects & tasks

    Project management with boards, Gantt charts and task tracking – the transparent alternative to proprietary project tools.

  • XWiki – knowledge management

    A structured knowledge base with templates, permissions and search – so documentation stays findable and stays in-house.

  • Identity & single sign-on

    Central identity management with Keycloak or Univention: one login for all services and a clean role and permission model.

  • Migration from Microsoft 365 & co.

    Structured migration of mailboxes, files and processes out of proprietary clouds – in waves, with a coexistence strategy and full traceability.

  • Operations, support & managed services

    We run your stack as a managed service or enable your team: updates, monitoring, hardening and support with clear SLAs.

Approach

How we introduce your sovereign workplace.

A proven five-phase approach – adapted to your regulatory environment, your existing landscape and your timeline.

  1. Assessment & target picture

    Analysis of infrastructure, data flows and sovereignty and compliance requirements; a shared target picture and business case.

  2. Architecture & operating model

    On-premises, a German/European hoster or a managed service? We define the architecture, the identity concept and coexistence with existing systems.

  3. Pilot & migration

    Pilot groups validate the stack and its acceptance; we then migrate mailboxes, files and processes out of legacy systems in waves.

  4. Rollout & adoption

    Organisation-wide rollout with training, champions and communication – the switch succeeds when people enjoy using the new tools.

  5. Operations & evolution

    Operations handed over or run by us as a managed service: updates, security and new components – your workplace grows with your needs.

Operating models

Sovereign means: the choice is yours.

The same stack is available in several operating models – what matters are your requirements for control, effort and regulation. Mixed models are common practice.

On-premises

Maximum control in your own data centre

  • Full sovereignty over data and infrastructure
  • Ideal for public sector, critical infrastructure and highly regulated industries
  • Integrates with existing identity and network concepts

Our focus: architecture, automation and enabling your operations team.

German / EU cloud

Sovereign hosting without your own data centre

  • Operated by German or European providers
  • GDPR-compliant without third-country transfers
  • Scalable without maintaining your own capacity

Our focus: provider selection, secure configuration and exit capability.

Managed service

Sovereignty without operational effort

  • dotmec operates your stack with clear SLAs
  • Updates, monitoring, hardening and support included
  • Predictable per-user costs instead of licence roulette

Our focus: reliable operations and continuous evolution.

Hybrid & coexistence

Sovereignty where it matters most

  • Open-source workplace alongside Microsoft 365
  • Sensitive data sovereign, commodity workloads pragmatic
  • Step-by-step transition instead of a big bang

Our focus: clean interfaces, clear data classification and a realistic roadmap.
