Voting control sits 100% with Deutsche Telekom AG, a German company. Economic majority is in the EU: DT is Frankfurt-listed with a majority free float, but the single largest anchor is the German state (~28.6% direct + KfW). Listing venue is EU (Frankfurt). Slight discount because DT also has a large US-listed ADR following and global institutional float.

Data & Infrastructure
55

T-Systems operates its own EU data centers and presents itself as a digital-sovereignty provider, which lifts it well above a pure US-hyperscaler reseller. But its flagship Sovereign Cloud line runs on Google Cloud (europe-west3) with customer-managed keys — T-Systems controls the sovereignty layer and operations, yet the underlying infrastructure provider is a US hyperscaler, and the technical docs do not claim CLOUD Act immunity. Mixed picture: genuine EU-operated infrastructure plus sovereign overlays on foreign cloud.

What we don’t know 3 open questions — they lower confidence, never the score
  • ?

    What share of T-Systems' actual production workloads runs on its own EU data centers versus on US-hyperscaler-backed sovereign offerings (Google Cloud, and any Azure/AWS-based services)?

    Directly determines whether the infra score should be higher (mostly own EU infra) or lower (mostly hyperscaler-dependent).

  • ?

    Geographic split of the ~27,000 workforce — how much delivery sits in non-EU centers such as India?

    Affects the operations score; a large offshore delivery base would lower EU-centeredness.

  • ?

    Whether the Google Cloud sovereign offering provides any contractual or legal shield against US CLOUD Act requests, beyond the technical CMEK/region controls.

    Central to real-world foreign-law exposure of customer data on that product line.

EU Cloud Sovereignty Framework lens

SEAL targets cloud providers; this is an analogous mapping for an EU IT-services subsidiary, not a certification.

Strategic

German champion: 100% Deutsche Telekom unit explicitly positioned around European digital sovereignty.

strong

Legal & jurisdictional

Incorporated and run in Germany (Frankfurt HRB 55933); fully within EU/German legal reach.

strong

Data & AI

Own EU data centers, but flagship sovereign cloud runs on Google Cloud (europe-west3) with customer-managed keys.

moderate

Operational

German HQ and leadership, EUR reporting; some non-EU global delivery centers.

strong

Supply chain

Sovereign offerings depend on US hyperscaler and software (Google Cloud; partnerships with SAP/others).

moderate

Technological

Strong integration/operations capability, but core cloud platform technology for sovereign line is supplied by Google.

moderate

Security & compliance

GDPR-aligned with German data-residency controls; no explicit CLOUD Act immunity claimed in technical docs.

Environmental sustainability

EU alternatives
🇫🇷 OVHcloud ovhcloud.com EU-controlled

EU-incorporated and EU-owned hyperscaler running its own data centers; stronger on infra sovereignty than hyperscaler-backed offerings.

🇩🇪 IONOS ionos.com EU-controlled

German cloud/hosting provider (United Internet group) operating its own EU infrastructure; a domestic peer for sovereign cloud.

🇫🇷 Atos / Eviden atos.net with caveats

EU IT-services peer to T-Systems, but financially strained in recent years; verify current restructuring/ownership before relying on it.

How the method works

Methodology v2 (provisional): the score is the midpoint of two axes — Control (who owns and governs the company) and Data (where your data lives and who can reach it). Each axis is scored only on verified evidence; unknowns reduce confidence, never the score. Every input below is sourced; the weights and judgments are open to challenge.
