Best Cloud Providers in Austria: Local Austrian Data Centers
- 11 hours ago
- 3 min read
U.S. laws such as the CLOUD Act and FISA 702 may compel U.S. providers (or their parents) to disclose data even if it sits in Europe. GDPR — including Article 48 — restricts such disclosures without an international agreement (for example an MLAT).

The safest path for many workloads is using fully Austrian-owned providers operating Austrian data centers under Austrian jurisdiction, without foreign parent-company control.
Selection Criteria - Best 5 Austrian Cloud Providers
Full Austrian ownership & HQ in Austria
Compliance: GDPR, ISO/IEC 27001; preference for EU-based certifications with verifiable scope
Services: IaaS/private cloud, managed cloud, backup/DR, security, connectivity
Local standing: Austrian facilities, references, and German-language support
Detailed Profiles of the Best 5 Fully Austrian-Owned Cloud Providers
Data centers (Austria): Vienna (DATASIX), Klagenfurt, and Graz. ANEXIA also operates internationally, therefore Austria-only region pinning and contractual data residency clauses are required for strict localization.
Services: IaaS and private cloud components (compute, storage, networking), managed hosting, managed Kubernetes and platform services.
Compliance: ISO/IEC 27001:2022 (valid 02 Nov 2024 – 01 Nov 2027, issuing body TÜV NORD; scope includes hosting and cloud services); ISO/IEC 27017/27018 referenced in certificate annexes; GDPR DPAs available.
Data centers (Austria): Salzburg-Maxglan and Hallein (two geo-redundant, provider-operated sites).
Services: Private cloud, hybrid cloud, managed infrastructure, colocation, network and security services delivered from Austrian facilities.
Compliance: ISO/IEC 27001:2022 (certified); EN 50600-certified data centers (design and operation); GDPR DPAs. Fully Austrian-owned via 50/50 split between Salzburg AG and MAMDa Beteiligungs GmbH (both Austrian entities).
Data centers (Austria): Vienna (two sites listed in ISO/IEC 27001 certification scope).
Services: Infrastructure and platform services, outsourcing, managed IT; primarily media and enterprise focused rather than hyperscaler-style public cloud.
Compliance: ISO/IEC 27001:2022 (certificate published by the provider; scope includes Vienna data centers); GDPR controls in place.
Data centers (Austria): Vienna (high-security government data center).
Services: IT and infrastructure services primarily for the Austrian federal administration and public sector; private-sector access may require special contractual arrangements.
Compliance: Operates under Austrian public-sector security and compliance frameworks; ownership: 100% Republic of Austria. Verify scope-specific certifications during procurement.
Data centers (Austria): Vienna (operated for Wiener Stadtwerke Group).
Services: Managed cloud and IT services mainly for Wiener Stadtwerke and municipal entities; external commercial availability is limited and must be verified case by case.
Compliance: ISO/IEC 27018:2019 (certified); ISO/IEC 27001 is claimed by the provider — request current certificate, issuing body, and scope during due diligence.
Practical Tips - Best 5 Austrian Cloud Providers
SLA / uptime & geo-redundancy: Ask for proof of multi-site operation inside Austria and documented failover procedures.
Certs & reports: Request current ISO/IEC 27001 certificate PDFs, validity dates, issuing bodies, and scope statements.
Jurisdiction controls: Austrian law venue; explicit Article 48 handling; no third-country disclosures without EU legal basis.
Data location & exit: Enforce Austria-only processing via contracts and technical controls (region pinning, logs, export formats, deletion confirmation).
Network: Verify local peering in Vienna and carrier diversity; ask about DDoS protection and security logging options.
Support: 24/7 German-language support, documented incident handling, and response SLAs.
Why Austrian-owned providers help with CLOUD Act/FISA risk
Foreign government data requests can conflict with GDPR Article 48 unless an international agreement applies. Using Austrian-owned providers reduces exposure to foreign parent-company obligations that may trigger such requests. Strong contracts, technical controls, and current audit evidence remain necessary, but legal jurisdiction and enforcement are clearer under Austrian ownership and operation.
