The Challenge
Digital infrastructure has to be flexible and meet strict legal standards
Business-critical systems need scalability and reliability. At the same time, the bar for data sovereignty and compliance keeps rising. Enterprises are forced to balance three competing priorities.
Sovereignty
Control over your own data.
Business-critical data should stay secure in Europe, independent of any non-European provider
Compliance
Legal certainty for sensitive data
Full GDPR compliance and protection from extraterritorial access.
Performance
Scale without compromise.
Modern platform services and highly scalable infrastructure for demanding workloads
The Pain Without a Sovereign Foundation
What's at stake without a sovereign cloud base
Extraterritorial access: Cloud infrastructure outside Europe is subject to laws like the US CLOUD Act, exposing data to foreign access.
Regulatory risk scales with you: With established hyperscalers, every expansion step scales not just performance but also your legal attack surface.
Compliance overhead: Running sensitive data across multiple regions and providers increases administrative burden and security risk
Dependency instead of independence: Without a sovereign platform foundation, you lack the digital independence to shape processes on your own terms.
The Solution: Sovereign cloud infrastructure with STACKIT
Hellgate runs its solution on STACKIT infrastructure, pairing high performance with digital independence. As an open, sovereign platform foundation, STACKIT combines capability with legal certainty. As a platform with European DNA, it decouples technological growth from regulatory risk: every scaling step grows performance only, while the legal attack surface stays minimized.
European DNA
Data processed exclusively in European data centers, free from extraterritorial access under laws like the US CLOUD Act.
Full compliance
Fully GDPR-compliant and rigorously certified, including BSI C5 Type 2 and ISO 27001.
Enterprise performance
Highly scalable infrastructure that combines demanding technical requirements with consistent legal compliance.
Payment sovereignty on sovereign cloud
Hellgate's Composable Payment Architecture gives you control over routing, tokenization, and provider strategy. STACKIT supplies the sovereign foundation that keeps that control legally sound. Both companies start from the same conviction: infrastructure should belong to the businesses that depend on it, not the providers that supply it.
