groupios for cities and municipalities

Digital sovereignty for cities

  • Built for cities, municipalities, and municipal IT service providers
  • Focused on digital sovereignty and data protection

The current situation

Municipal responsibility is often underestimated - especially in IT

Every day in your administration, it's decided whether citizens' data is protected, whether the administration stays operational - and whether citizens' trust holds.

What's at stake every day:

  • Citizens' data - registration, health, social, and tax data are your responsibility.
  • Operational capability - an outage affects not just IT, but the entire municipal administration.
  • Citizens' trust - what took decades to build can be destroyed by a single incident.

The reality is:

  • IT departments are overloaded - amid growing requirements
  • Cyberattacks on municipalities are increasing massively and are increasingly targeted
  • Compliance requirements under GDPR and NIS2 keep rising
  • Grown IT systems increase complexity and attack surface

What a successful attack means

  • Complete standstill of the administration - sometimes for weeks
  • Loss of sensitive citizens' data - with mandatory reporting and fines
  • Loss of trust in your institution and your political decisions
  • Public media coverage and reputational damage
  • High recovery costs - internal and external
  • And the responsibility always rests with you - not with the provider, not with IT.

Security must not be left to chance. A managed service is not an IT decision. It's a decision about how seriously you take your responsibility toward the citizens of your municipality.

The strategic answer

Why a managed service is a political decision

This isn't about technology. It's about the ability to act - today and in the future.

Security is never left to chance

Systems stay current and protected at all times, with no operational effort on your part.

Your administration stays operational

Even while others are under attack. Resilience is something you can plan for.

Complexity is reduced

One central platform instead of fragmented solutions and parallel systems.

Trust is actively protected

Through demonstrable security and seamless compliance.

Digital transformation - safely!

The integrated security architecture of the groupios Mare Cloud

Three structural reasons - not technical arguments, but questions of political responsibility.

Independence from hyperscalers - control is a duty

Many municipalities give up control without realizing it. Data held by international providers means decisions get outsourced and transparency is lost.

  • Data resides with international providers with no control over it
  • US providers are subject to the CLOUD Act - your data too
  • Transparency over data processing is lost
  • Government responsibility must not be outsourced

Protection of personal data - trust is your capital

Citizens trust your municipality: with their data, their concerns, their safety. That trust isn't a given and can be destroyed at any time.

  • Encrypted communication protects every message
  • Audit-proof archiving - seamless and provable
  • GDPR-compliant data processing on German servers
  • No fines, no loss of trust

Digital sovereignty - the foundation of your ability to act

Without digital sovereignty, there's no sustainable administration. Whoever doesn't control their own infrastructure gradually loses the ability to act independently.

  • Make your own decisions - with no external dependencies
  • Control your infrastructure - completely and transparently
  • Stay independent - from providers, platforms, and policies
  • Long-term planning security for your IT infrastructure

What decision-makers want to know…

Why should we, as a municipality, commission a managed service at all?

Because your IT department can’t handle operations, maintenance, security, and rising compliance requirements all at once. A managed service takes exactly that off your hands - completely and permanently. Your administration stays operational, your IT is relieved, and security isn’t sacrificed to day-to-day business. This isn’t an IT decision - it’s a decision for your municipality’s ability to act.

How exactly does the Mare Cloud protect our citizens' data?

Through a layered protection architecture: the Email Security Gateway stops attacks before they reach your systems. S/MIME encryption protects every single message. Audit-proof archiving records every communication process seamlessly. And Multi-Node Backup ensures data can be restored even after an attack - all on German servers, fully GDPR-compliant.

Are we independent of US providers with the Mare Cloud?

Yes - completely. The groupios Mare Cloud is a European solution explicitly designed for digital sovereignty. All data is processed and stored on German servers. There’s no dependency on US providers subject to the CLOUD Act. Your municipality retains full control over data, systems, and communication channels - with no external dependencies.

Does the Mare Cloud help us meet our GDPR and NIS2 obligations?

The Mare Cloud structurally supports compliance with both regulations: GDPR-compliant data processing, complete logging of all communication processes, and audit-proof archiving provide the evidence base needed for audits. NIS2 requirements for risk management, reporting obligations, and resilience are specifically addressed by the integrated platform architecture.

How does the rollout work - and how long is our administration unreachable during it?

Implementation is structured and guided by our team of experts - with no interruption to ongoing operations. Since the Mare Cloud is fully managed, complex self-installation isn’t required. The switchover is planned so your administration is never unreachable. Within a short time, your municipality is fully protected and ready to go.
