Four digital sovereignty tools compared

Four approaches, one question: How sovereign is your IT really? We compare the digital sovereignty tools from Red Hat, SUSE, Deloitte, and Nextcloud and show what really matters when it comes to digital sovereignty.

Red Hat enters the market

With the release of its Digital Sovereignty Readiness Assessment Tool in February 2026, Red Hat is responding to growing pressure from global regulations that are forcing organizations to strengthen operational resilience and data sovereignty. The open source online tool, currently available in English only, allows decision makers to evaluate the current state of their digital sovereignty through a structured set of questions and assess their control over digital assets and software stacks.

The approach focuses primarily on technical independence: it examines whether systems can be maintained without external assistance, whether vendor lock-in can be avoided through community-driven approaches, and how flexibly cloud environments can be deployed across regions. The result is a classification into four maturity levels, ranging from the initial identification of requirements to proactive control over the entire infrastructure, complemented by a concrete roadmap with actionable recommendations.

A differentiated market

Although Red Hat addresses an important gap, the market for sovereignty assessments is already more nuanced. A key competitor is SUSE, which places a strong emphasis on compliance with EU standards through its Cloud Sovereignty Framework Self Assessment and classifies organizations into so-called SEAL levels (Sovereignty Effective Assurance Levels). These do not describe classic IT security classifications but graduated degrees of digital sovereignty, from level 0 (no sovereignty) to level 4 (full operational control), making them particularly relevant for public authorities and highly regulated industries in the EU.

While Red Hat emphasizes technological openness, Deloitte offers a Sovereign Cloud Assessment through its professional services division that is structured as a guided consulting process spanning several weeks. For a data-centric comparison, Nextcloud provides the Digital Sovereignty Index (DSI), a platform for making sovereignty measurable at the organizational level, with a particular focus on GDPR compliance and data processing within the EU.

Where the Red Hat approach should be supplemented

To develop a truly comprehensive strategy, organizations should supplement Red Hat’s approach with several critical elements that remain underrepresented in the current tool.

Legal sovereignty is one such gap. The tool does not explicitly examine which foreign access rights apply to the providers being used. Particularly relevant here is the US CLOUD Act (Clarifying Lawful Overseas Use of Data Act), which grants US authorities worldwide access to data held by American cloud providers, as well as FISA Section 702, which permits intelligence surveillance without a court order. British and Chinese data access laws may also be relevant for globally operating organizations.

Economic sovereignty is another missing dimension. The tool currently lacks any analysis of long-term costs, and in particular egress fees that arise when switching providers. A genuine exit strategy must systematically account for these economic dependencies.

Personnel capability rounds out the picture. Even the best open source infrastructure is of little use if the internal know-how to operate it without vendor support is missing. An evaluation of internal technical expertise is entirely absent from the tool at this point.

Only the combination of technical control, legal safeguarding, and personnel capability leads to truly comprehensive digital sovereignty.

Focus and criteria in comparison

The Red Hat Digital Sovereignty Readiness Assessment Tool focuses primarily on technological and strategic independence. It specifically assesses the degree of control over digital assets and whether the organization is capable of maintaining or validating systems without external assistance. A central theme is the avoidance of vendor lock-in through community-driven open source approaches, as well as geographic flexibility in deploying cloud environments. Red Hat classifies organizations into four maturity levels, ranging from the initial identification of needs to comprehensive proactive control.

By contrast, the SUSE Cloud Sovereignty Framework Self Assessment places greater emphasis on regulatory compliance within the European context. While Red Hat emphasizes general resilience, SUSE is oriented around SEAL levels that describe sovereignty grades from 0 to 4. This enables a precise classification that goes beyond mere software control and is especially decisive for public authorities and highly regulated industries in the EU.

Complementary approaches: Deloitte and Nextcloud

The Deloitte approach differs fundamentally from online self-assessments. Its Sovereign Cloud Assessment is a structured three-step process conducted over four to six weeks. The focus is not on a technical inventory but on an in-depth business case analysis with strategic roadmaps that address not only IT infrastructure but also business impact and governance structures.

Nextcloud complements this landscape with the Digital Sovereignty Index (DSI), a platform-based self-assessment focused on data sovereignty, GDPR compliance, and the use of European cloud infrastructure. Unlike the technology-oriented approaches of Red Hat and SUSE, the DSI foregrounds the organizational perspective: which data is being processed, where, how, and by whom? This makes it particularly suitable for organizations that want to systematically assess their data protection status.

	Red Hat	SUSE	Deloitte	Nextcloud DSI
Focus	Tech Autonomy	EU Compliance	Business Strategy	Data-Centricity
Format	Online Self-Assessment	Online Self-Assessment	4–6 Week Consulting	Online Platform
Maturity Model	4 Levels	SEAL-Level 0–4	Individualized	Index Value
Regulation	General	EU-Specific	Industry-Specific	GDPR-Focused
Open Source	Central	Relevant	Subordinate	Central
Cost	Free	Free	Paid	Free

By combining these approaches, organizations gain a complete picture. Red Hat helps to understand the current state of one’s IT, while SUSE examines EU compliance, Nextcloud evaluates data sovereignty, and Deloitte accompanies long-term strategy.

A holistic checklist for digital sovereignty

To assess the status of your IT infrastructure beyond the tools offered by Red Hat or SUSE, the following points should be addressed.

On technical control: can all critical systems be maintained without external assistance and restored in an emergency? On auditability: is it possible to independently validate the integrity of software and source code through open source principles? On vendor lock-in: are proprietary interfaces being avoided in favor of community-driven standards? On data sovereignty: is the physical storage location of data freely selectable within specific regions or your own data centers? On legal certainty: has it been verified whether providers are subject to foreign access rights, such as the US CLOUD Act, FISA Section 702, or comparable national regulations? On economic viability: have the costs of switching providers, including an exit strategy with egress fees, been calculated and found to be manageable? On personnel capability: does the internal team have the necessary skills to ensure sovereignty operationally and independently of any vendor?
