One secure messenger for public administration
Wire gives cities, municipalities, and local authorities a practical way to protect citizen data, personal records, and sensitive administrative information.
While email still dominates office work and frontline teams rely on unmanaged consumer messengers, Wire replaces this fragmented setup with a single, government-grade messenger—secure, compliant, and easy to use on mobile and desktop.

Secure by design, usable for everyone
Protecting citizen data and sensitive administrative information is a basic requirement for municipalities. Wire is built for this reality— secure by default, without adding complexity for users or IT.
- Always-on end-to-end encryption: Messages, files, and calls are protected automatically. No setup, no exceptions.
- Public-sector compliance: Supports GDPR and relevant EU data-protection and security requirements for city and municipal administrations.
- Simple for everyday use: Designed for non-technical staff in administration and the field—without compromising security, control, or auditability. Available on mobile and desktop.
- One messenger for the entire municipality: Administration, councils and committees, IT and information security, crisis response, and coordination with external partners—all in one platform.
A secure, sovereign messenger for the public sector
Wire is a European, government-grade messenger built to public-sector security standards. End-to-end encrypted, auditable, and proven in daily use across platforms.
- Trusted security at government standard: End-to-end encrypted messaging, calls, and file sharing—built on the same core security architecture as Wire Bund, which is approved for VS-NfD use in the German federal context.
- Digital sovereignty and full control: Deploy in EU Public Cloud, Private Cloud, or On-Premises. Supports GDPR, NIS2, and sovereign IT architectures for public administrations.
- Secure collaboration across organizations: With Wire Federation, departments, municipal companies, and other public entities communicate securely—while maintaining clear separation and trust boundaries
- Resilient fallback communication: A reliable channel during outages, cyber incidents, or failures of other collaboration tools—for office staff, field teams, and crisis units.

City of Groß-Gerau
(Hesse, Germany)
As part of its digitalization initiative, the City of Groß-Gerau uses Wire to enable secure communication for its Digitalization Ambassadors and key administrative roles. The city acts as a lighthouse municipality and reference partner, demonstrating how cities can adopt sovereign communication for modern, resilient governance.


Governed communication across the municipality
Wire gives municipalities full administrative control over users, groups, and sensitive information—clearly structured, auditable, and without operational overhead.
- Role-based access control: Only authorized users can access sensitive conversations, files, and groups.
- Secure multi-tenancy: Departments, utilities, schools, municipal companies, and external partners work in logically separated environments on one trusted platform.
- Central user and group management: Create or remove users centrally, revoke access instantly, and prevent outdated or uncontrolled group memberships.
- Verified identities with ID-Shield: Only verified users participate in confidential communication.

Leadership & Governance
Typical challenge
Daily coordination spans city hall, external facilities, utilities, and contractors. Email is slow and unusable on mobile. WhatsApp fills the gap but is not governable, auditable, or compliant.
How Wire is used
✅ Secure coordination between departments and city hall
✅ Communication with external facilities (e.g. building yards, swimming pools, utilities)
✅ Collaboration with external contractors and service providers
✅ Mobile communication for field staff without intranet or VPN access
✅ Secure reporting and whistleblower-style internal channels
Outcome
Wire replaces the email–WhatsApp split with one governed system that works on desktop and private mobile devices. Cities regain control over communication flows, group memberships, and sensitive operational information—without adding IT complexity.
Typical challenge
During cyber incidents, outages, or emergencies, email, phones, or collaboration tools often become unavailable. Municipalities lack a secure, independent fallback channel.
How Wire is usedt
✅ Crisis and emergency coordination across departments
✅ Out-of-band communication during IT or infrastructure outages
✅ Cyber incident and data breach response
✅ Disaster response and recovery coordination
✅ Secure communication when Teams, email, or telephony are unavailable
Outcome
Wire serves as a resilient fallback channel that remains operational when other systems fail. Many municipalities start with Wire as a crisis tool—and then expand it into everyday communication once it is established and trusted.
Typical challenge
Sensitive discussions still happen via email, phone calls, or unmanaged messenger groups. This creates legal, security, and reputational risk for leadership and councils.
How Wire is used
✅ Secure communication for mayors and executive leadership
✅ City council and committee coordination
✅ Legal, compliance, and regulatory discussions
✅ Confidential negotiations and policy development
✅ Strategic planning and budget coordination
Outcome
Leadership communication is protected, auditable, and governed. Wire supports compliance with public-sector requirements while remaining simple enough for non-technical users—removing the temptation to fall back to consumer tools.
