The digital transformation of local authorities is no longer just about digitizing forms. For the past two years, new technological building blocks (generative AI, national digital identity, digital twins of territories) have been changing the very nature of local public services. Comparing these solutions based on their maturity and their real impact on agents and citizens allows us to distinguish between structuring projects and mere announcements.
Maturity of digital solutions deployed in local authorities
The digital tools adopted by local authorities do not all have the same level of deployment or measurable effect. The table below positions the main solutions in relation to their stage of adoption and their operational impact.

| Solution | Stage of adoption | Main impact | Example of territory |
|---|---|---|---|
| Generative AI assistants (conversational chatbots) | Advanced experimentation | Reduction in phone calls to counters, off-hours responses | Lyon Metropolis, City of Nanterre |
| France Identity digital identity | Ongoing pilots | Strong authentication without a local account, redesign of e-services | Pilot authorities (ANTS) |
| Digital twins of territories | Industrialization | Simulation of public policies (mobility, climate, planning) | Occitanie Region, European Metropolis of Lille |
| NIS2 compliance and cybersecurity | Mandatory compliance | Review of IT architectures, resource sharing | Many authorities (directive transposed in 2024) |
What stands out from this overview is that local authorities are advancing on several fronts simultaneously, but the level of maturity varies greatly from one project to another. Generative AI remains experimental, while regulatory obligations like NIS2 impose a non-negotiable timeline.

Generative AI in local public services: beyond the gadget
The conversational virtual assistants deployed since 2023 in certain metropolises do not operate like traditional decision-tree chatbots. They rely on language models capable of understanding freely formulated queries from citizens (civil status, waste collection, mobility).
Feedback from Lyon Metropolis and the City of Nanterre shows a notable decrease in phone calls to counters and an improvement in the response rate outside of opening hours. This last point changes the game for users who work during the day and do not have access to services during regular hours.
The challenge remains the reliability of the responses. An AI assistant that provides incorrect information about a right or an administrative deadline exposes the authority to reputational risk. Agents must supervise the knowledge bases injected into these tools, which requires skill development and dedicated time.
France Identity and the redesign of municipal e-services
The gradual rollout of the France Identity service, led by the National Agency for Secure Documents, is beginning to transform the design of local e-services. The principle is to allow citizens to authenticate themselves without creating a specific account with each municipality or intercommunal authority.
This approach eliminates a major friction point. Each authority that developed its own identification system had to manage the security of associated data, forgotten passwords, and duplicate accounts. With a national digital identity, these technical layers are outsourced to a centralized infrastructure.
Pilot authorities are starting to integrate this building block into their online processes. The direct consequence for local digital projects is a redesign of existing forms and workflows, not just a simple addition of a login button.
Digital twins of territories: simulate before deciding
The Occitanie Region and the European Metropolis of Lille have been industrializing approaches to digital twins of territories since 2023. These virtual replicas go beyond geographic information systems or traditional dashboards.
A digital twin allows for simulating the impact of a public policy before its implementation:
- Testing a new mobility plan and visualizing its effects on traffic, emissions, and accessibility of peripheral neighborhoods
- Anticipating the consequences of a development project on heat islands or flood risks
- Co-constructing scenarios with elected officials and citizens based on updated local data, not theoretical projections
The interest for public management is direct: budgetary decisions are based on simulations rather than estimates. However, the quality of the twin entirely depends on the quality and freshness of the injected data, which relates to the capacity of authorities to structure their data assets.
Cybersecurity and the NIS2 directive: the non-optional project
The transposition into French law of the European NIS2 directive in 2024 places many local authorities in the category of essential or important entities. The consequences are concrete: in-depth revision of IT architectures and resource sharing for security.
For small and medium-sized authorities, this regulatory obligation poses a resource problem. Hiring a dedicated cybersecurity officer often exceeds the available budget. Sharing resources between intercommunalities or through mixed digital syndicates then becomes the most realistic response.
- Audit of existing systems and risk mapping, prerequisites before any compliance
- Sharing intrusion detection tools among authorities in the same territory
- Training agents on common risks (phishing, ransomware), the first identified attack vector
NIS2 is not a barrier to digital transformation. It is a foundation that conditions citizens’ trust in online services. An authority that falls victim to a personal data leak will see the adoption of its e-services decline sustainably.
The key takeaway from this overview is that local authorities that progress the fastest are those that treat cybersecurity, digital identity, and decision-support tools as a coherent whole, rather than as isolated projects. Solutions exist; their integration remains the real challenge.
