Microsoft agrees to store and process all European customer data within the EU under European law

Microsoft is tightening its data sovereignty protocols in Europe in response to regulatory pressure and mounting concerns among European enterprises and governments about foreign access to sensitive information. 

In a move revealed Monday, the company said it will now store and process all European customer data entirely within the region, under European law, with operations monitored by personnel based in Europe.

The commitment is part of Microsoft’s ongoing push to expand its AI and cloud footprint across Europe, while simultaneously staying ahead of increasingly strict digital sovereignty expectations set by the European Union and national regulators.

Regulatory pressure leads to commitment to local operations

According to Microsoft, any remote access by engineers outside the EU to European customer data systems will require real-time approval and monitoring by EU-based staff. The company emphasized that European clients will retain full control over their data in compliance with regional legal frameworks, notably the General Data Protection Regulation (GDPR).

The initiative includes the launch of a sovereign cloud infrastructure, currently in preview, which will be generally available later this year. It promises physical and operational separation from Microsoft’s global cloud, tailored for public sector clients and heavily regulated industries such as banking, defense, and healthcare.

The EU’s GDPR already requires strict safeguards on personal data, but new legislation such as the Digital Markets Act (DMA) and the Data Act impose additional layers of compliance on large technology firms.

European lawmakers and privacy advocates have long raised concerns that U.S. laws, such as the CLOUD Act, could compel American tech companies to hand over data stored in foreign jurisdictions, including EU countries. That tension has led many European organizations to demand stronger assurances and technical controls that prevent cross-border data access, even in the face of legal requests from U.S. authorities.

Brad Smith, Microsoft’s President and Vice Chair, has previously acknowledged this challenge, stating in April: “Like every citizen and company, we don’t always agree with every policy of every government. But even when we’ve lost cases in European courts, Microsoft has long respected and complied with European laws.”

Competing for the sovereign cloud market

Microsoft’s announcement also reflects an increasing competition among hyperscalers for dominance in the European cloud market. While Amazon Web Services (AWS) and Google Cloud remain formidable players, Microsoft’s early and detailed embrace of data localization could help it gain favor with cautious governments and corporations.

In April, Microsoft pledged to build over 200 data centers as part of its cloud and AI infrastructure investments across 16 European countries by 2027. That includes the construction of new data centers in Germany and France, which are designed to meet country-specific legal requirements.

The company’s new offerings will include support for customer-managed encryption keys, audit transparency logs, and isolated cloud environments that meet the criteria of the EU Cloud Code of Conduct and potentially align with Gaia-X, the pan-European data infrastructure initiative.
