With the September 2026 deadline , approximation wasn't an option.
For this French software provider, specialised in the dematerialisation and security of information flows, the challenge was twofold: transforming a legacy technical foundation (80% .NET) into a certified sovereign platform, ready to absorb regulatory change, while sustaining a strong pace of innovation.
Novity provided technical support to secure this trajectory, aligned with State requirements.
Key Challenges
Achieving "Approved Platform" (PA) registration required absolute standards of reliability and security, while also becoming a genuine commercial differentiator.
The operational and technical challenge was threefold:
- Technical expertise: Strengthening delivery capacity on the .NET foundation while initiating a transition to Java microservices.
- Sovereignty: Complying with strict standards (ISO 27001, GDPR, SecNumCloud), requiring a deep and strategic infrastructure migration.
- Regulatory agility: Continuously adapting to a shifting legislative framework and constant updates to official specifications throughout the project.
Collaborative Execution
Novity mobilised a team of senior experts to support the client's internal tech teams.Working under a fully integrated approach, our engineers maintained and evolved the .NET foundation, freeing up the client's internal talent to focus on future architecture.
This stability — with Software & Product Engineering consultants engaged since 2022 — made it possible to build deep business knowledge, essential for navigating the complexity of fiscal data flows.
Measurable Impact
The client is approaching the reform with a head start. The sovereign platform is ready for 2026:
- Accreditation secured: Approved Platform (PA) registration was obtained, placing the client among the first 100 accredited solutions and confirming the reliability of the work delivered.
- Continuity ensured: the legacy .NET stack was evolved with zero operational disruption.
- Competitive advantage: the client now offers a future-proof solution, capable of handling critical data volumes with optimal security.
