Legal pitfalls with US providers
The US CLOUD Act enables US authorities to access data extensively – even on European servers – which fundamentally conflicts with EU data protection principles. Following the collapse of Privacy Shield and the restrictions on Standard Contractual Clauses imposed by the ECJ (Schrems II decision), there's no legally secure foundation for transatlantic data transfers. Companies must therefore navigate a constant balancing act between practical necessity and legal compliance, risking GDPR fines whilst losing control over their sensitive data.
Another risk is so-called vendor lock-in – dependence on a single technology provider where switching to another solution would involve significant costs, technical hurdles or data loss.
When the service fails: Business risks
There are countless examples of this risky dependence: In April 2022, Google Cloud failed across Europe when cooling problems following a power outage brought numerous services to a halt for over eight hours. This affected not only email systems, but also business-critical applications hosted in Google Cloud. Microsoft's Exchange Online went down for over five hours in January 2023. Email communication ground to a complete halt in thousands of companies.
The most recent example is the disruption to the International Criminal Court's (ICC) work after Microsoft blocked Chief Prosecutor Karim Khan's email account following sanctions imposed by US President Donald Trump. This time it wasn't a technical failure, but the consequence of political decisions. What these examples share isn't just their cost to affected companies and institutions, but above all the dramatic importance of a diversified IT strategy and the urgency of switching to European alternatives without delay.
European alternatives as the solution
To avoid dependencies, increasing numbers of companies are turning to European alternatives to the US giants. These solutions offer not only legal security, but also strengthen their own digital sovereignty. Those choosing this path should look carefully though, as not every European provider meets the requirements of modern business communication.
For a future-proof email solution, several key requirements must be met:
Security as the foundation
Modern email providers should meet the highest security standards. End-to-end encryption with PGP or S/MIME, two-factor authentication and intelligent systems to ward off spam, phishing and malware form the foundation. European providers often place particular emphasis on these security functions, as they operate in a stricter regulatory environment than their US competitors.
Data protection as competitive advantage
GDPR compliance isn't just a legal obligation, but can also be a strategic advantage. With European alternatives, companies should look for providers designed from the ground up for these requirements – with servers exclusively in the EU and transparent data processing procedures. A privacy-friendly approach supports companies in fulfilling their compliance obligations and strengthens trust with customers and business partners.
Seamless integration into corporate IT
A contemporary business email service is an integral part of a company's entire IT landscape. It connects seamlessly with existing systems via open APIs, offers comprehensive collaboration functions (calendar, contacts, office, drive, video conferencing) and grows flexibly with the company's requirements. This integration reduces media breaks and increases business process efficiency whilst maintaining data sovereignty.
