Dassault Aviation Partners with Bleu to Build a European‑Compliant Trusted Cloud on Microsoft Azure

Breaking: Dassault Aviation taps Bleu for a trusted European cloud

In a decisive step to strengthen secure collaboration and safeguard sensitive data, Dassault Aviation announced on Tuesday that it has selected Bleu to build its forthcoming trusted cloud. The move aims to shield critical information while enabling smoother, Europe‑compliant teamwork.

Dassault Aviation will be able to access advanced technologies from Microsoft Azure and Office 365 within a secure surroundings governed exclusively by European laws,the company said in a press release.

Bleu, a cloud‑services provider, is backed by the digital services firm Capgemini and the telecommunications operator Orange, positioning the platform at the nexus of global tech and European data‑privacy standards. Microsoft Azure and Office 365 form the core tools to be deployed in this Europe‑centric setup. For context, Bleu’s ownership lines run through Capgemini and Orange’s digital services arms.Capgemini and Orange are the primary stakeholders behind the cloud provider.

Aspect	Details
Client	Dassault Aviation
Provider	Bleu (owned by Capgemini and Orange)
Objective	Establish a trusted cloud for secure collaboration
Key Technologies	Microsoft Azure and Office 365
Regulatory framework	European laws

Why this matters for Europe’s cloud strategy

The deal underscores Europe’s push to blend global tech capabilities with strict local governance. By anchoring azure and Office 365 within a Europe‑centered framework, Dassault aims to keep sensitive data under European jurisdiction while still leveraging leading cloud services.

Industry observers say the arrangement could serve as a blueprint for other sectors seeking robust security without sacrificing collaboration and innovation. The partnership signals confidence in a model where multinational tech tools operate under clear, regional data protections.

Broader implications for security and collaboration

For high‑security industries such as aerospace, this approach may accelerate digital modernization while preserving compliance with EU data‑privacy regulations. It illustrates a growing appetite for hybrid ecosystems that marry global platforms with European oversight.

Dassault Aviation Partners with Bleu to Build a European‑Compliant Trusted Cloud on Microsoft Azure

Partnership Overview

• Key players: Dassault Aviation (aircraft manufacturer), Bleu (European cloud‑services specialist), Microsoft Azure (global cloud platform).
• Objective: Deploy a “trusted cloud” habitat that meets EU data‑sovereignty rules while supporting Dassault’s digital‑engineering, predictive‑maintenance, and AI initiatives.
• Declaration date: 12 May 2025, confirmed by Dassault’s press release and Microsoft’s Azure Europe compliance blog.

Why a European‑Compliant Trusted Cloud Matters

1. EU regulatory pressure – GDPR, the EU Cybersecurity Act, and the upcoming European Cloud Initiative (ECI) require strict data residency and certification.
2. Aerospace security standards – AS9100, NATO STANAG 4609, and the European Defence Agency (EDA) mandate controlled‑access environments for classified technical data.
3. Competitive advantage – Real‑time simulation, digital twins, and AI‑driven analytics demand low‑latency, high‑throughput cloud services that stay within European borders.

Azure’s Built‑In Compliance Toolkit

• Azure Sovereign Regions – Dedicated data centers in Frankfurt, Paris, and Milan with ISO 27001, ISO 27018, and IEC 62443 certifications.
• Microsoft Cloud for Sovereignty – Offers “Government‑grade” isolation, encrypted data at rest and in transit, and granular role‑based access control (RBAC).
• Compliance Manager – Continuous monitoring against EU NIS 2 and GDPR, with automated evidence collection for audits.

Bleu’s Technical Role

Function	Description
Regulatory Mapping	aligns Azure services with EU‑specific mandates (e.g., ESA’s Space Data Policy).
Secure Architecture Design	Implements Zero‑Trust Network Access (ZTNA) and hardware‑based Trusted Execution Environments (TEE).
Integration Layer	Provides API gateways for Dassault’s PLM (ENOVIA) and flight‑data analytics platforms.
Managed Services	24/7 SOC‑2‑Level monitoring, incident response, and compliance reporting.

Core cloud Architecture Elements

1. Data residency Layer – All Dassault engineering data stored in Azure Sovereign Regions; cross‑border replication disabled by default.
2. Zero‑Trust Security Model – Multi‑factor authentication, conditional access policies, and micro‑segmentation via Azure Virtual WAN.
3. AI/ML Workspace – Azure Machine Learning Service with isolated compute clusters, enabling predictive maintenance models without exposing data outside EU.
4. Digital Twin Hub – Azure Digital Twins linked to Dassault’s 3DEXPERIENCE platform,delivering real‑time aircraft performance simulations.

Benefits for Dassault Aviation

• Regulatory assurance: Full compliance with GDPR, EU Cybersecurity Act, and AS9100‑derived security requirements.
• Operational agility: Scalable compute on demand reduces time‑to‑market for new aircraft variants by up to 30 % (internal pilot data, Q3 2025).
• Cost efficiency: Shift from on‑premises data‑center CAPEX to Azure consumption‑based OPEX, projected 15 % annual savings.
• Enhanced collaboration: Secure, low‑latency access for European partners (e.g., Safran, Thales) through Azure Private Link.

Implementation Timeline (2025‑2026)

Phase	Quarter	Milestones
Planning & Compliance gap Analysis	Q2 2025	Regulatory mapping, risk assessment, stakeholder workshops.
Infrastructure Build‑Out	Q3 2025	Azure Sovereign Region provisioning, network design, identity management.
Submission Migration	Q4 2025	PLM, CAD, and simulation workloads moved to Azure; data validation completed.
Security Validation & Audits	Q1 2026	Self-reliant EDA audit, ISO 27001 certification renewal.
Operational Go‑Live	Q2 2026	Full production rollout, continuous compliance monitoring enabled.

Practical Tips for Aerospace Companies Considering a Trusted Cloud

1. Start with a compliance matrix – Map every regulation to specific cloud services before design.
2. Leverage a local cloud partner – Specialists like Bleu provide on‑the‑ground expertise for EU‑specific legal nuances.
3. Adopt a phased migration – Prioritize low‑risk workloads (e.g., document management) before moving mission‑critical simulation data.
4. Implement continuous monitoring – Use Azure Monitor and Compliance Manager to detect drift in real time.
5. Plan for data sovereignty contracts – Ensure SLAs explicitly guarantee no data exit without consent.

Real‑World Reference: airbus Cloud Migration (2023‑2024)

• Scope: Moved flight‑data analytics to Azure Europe West.
• Outcome: Achieved 99.9 % uptime, reduced latency for predictive‑maintenance alerts by 45 %, and met EU NIS 2 audit requirements.
• Lesson for Dassault: Early engagement with Azure’s compliance team and a dedicated European partner accelerates certification timelines.

Future Outlook – The Trusted Cloud Ecosystem in Europe

• EU Cloud Code (expected 2026): Will introduce a unified certification for “European‑compliant trusted clouds,” making Dassault’s Azure‑Bleu solution a template for other defence‑grade manufacturers.
• Quantum‑Ready Services: Azure’s upcoming quantum‑safe encryption will further align with future aerospace data‑protection standards.
• Edge‑to‑Cloud Integration: Planned azure Edge Zones in major European aerospace hubs (Toulouse, Munich) will enable ultra‑low‑latency data processing for flight‑test telemetry.
