The three rings of risk in your martech stack
Not every system in your marketing technology stack carries the same sovereignty risk. A form tool that processes personal data is a different story than a CDN that distributes static files. Yet in sovereignty discussions, they are often lumped together. This article brings structure with a model of three impact layers — so you know where to start.
The heart of your marketing and sales organization
At the center of the model are the three systems your organization relies on and where the most sensitive data is stored: your CRM or CDP, your marketing automation platform, and your CMS or DXP.
These are the systems that store customer and contact data, track visitor behavior, process campaign data, and manage content based on customer profiles. If any of these systems falls under American jurisdiction, the entire data domain is legally exposed — via the CLOUD Act without judicial review on the European side.
The lesson: your core systems are where the urgency is greatest. Not just because of the volume of data, but because of its nature: personal data, behavioral data, transaction history.
Tools that process customer data or indirectly touch personal data
The middle ring contains tools that are not the primary system of record, but do process data that can be traced back to individuals. Analytics tracks visitor behavior and IP addresses. Forms capture names, email addresses, and sometimes medical or financial information. Personalization engines build visitor profiles. Email delivery sees all recipient addresses pass through.
It is precisely this operational layer where dependencies are overlooked. Organizations replace their CMS, but forget that their form tool, consent management, and analytics still run on American vendors.
The lesson: the operational layer is where the "hidden" risks lie. A Sovereignty Scan maps them out systematically.
Infrastructure that doesn't process direct customer data, but does create dependency
The outer ring contains tools and services that don't process customer data in the traditional sense, but do create dependencies that undermine your sovereignty. Hosting is the most fundamental example: if your infrastructure provider is American, technically all data stored on it falls under US jurisdiction.
A seemingly small risk: web fonts. Google Fonts loads fonts from googleapis.com and in doing so sends your visitors' IP addresses to Google servers. In Germany, GDPR fines have already been issued for this. The solution is trivial — host your fonts locally.
The lesson: the facilitating layer is not urgent in terms of direct data exposure, but it is the foundation. If the foundation is not sovereign, your entire stack rests on shaky ground.
The 2026 coalition agreement makes digital autonomy a guiding principle. Organizations that start inventorying and planning now will have a sovereign stack in 9–12 months. Organizations that wait until they have to will migrate under time pressure.Based on the 2026–2030 coalition agreement and the government's Vision on Digital Autonomy
Frequently asked questions
What is digital sovereignty in the context of martech?
Digital sovereignty in martech means that you have full legal and technical control over your marketing technology stack. It's not just about where your data is stored (data location), but also about which legislation applies to it (jurisdiction). If your CMS, analytics, or marketing automation runs on an American provider, your data falls under the US CLOUD Act — even if the servers are located in Europe.
A sovereign martech stack consists of tools that fall entirely under European jurisdiction.
Why is the CLOUD Act a risk for my marketing stack?
The CLOUD Act (2018) gives the US the right to request data from any American-controlled provider, regardless of where that data is physically stored. FISA Section 702 goes even further and enables bulk surveillance of non-American individuals.
This applies to all major US cloud providers and SaaS platforms — including the tools in your martech stack. In practice: if your CMS runs on an American vendor, the US can request your content and customer data without you or a European regulator being notified.
Can I make my existing martech stack sovereign without replacing everything?
Yes. Blastic takes a phased approach. We start with a Sovereignty Scan to map out your risk profile. Then we design a composable architecture with European vendors and migrate step by step, starting with the most critical components.
You don't have to replace everything at once — and you don't sacrifice any functionality.
What European CMS alternatives are there for WordPress or Contentful?
There are an increasing number of powerful European CMS platforms. Plate CMS is a Dutch CMS that recently migrated to fully Dutch hosting at Info Support. Prepr is an Amsterdam-based headless CMS with built-in personalization and A/B testing.
In addition, Umbraco (Denmark) and Kentico (Czech Republic) are strong European DXP platforms that Blastic implements as a partner.
What does a Sovereignty Scan cost?
The Sovereignty Scan is a no-obligation 45-minute conversation in which Blastic maps out the critical dependencies in your current martech stack. There are no costs involved.
You receive a clear overview of your risk profile and concrete recommendations for a sovereign martech stack.
Is digital sovereignty only relevant for the public sector?
No. Although the government is leading the way with the 2026 coalition agreement in which digital autonomy becomes a guiding principle, the topic is broadly relevant. Organizations in healthcare, financial services (DORA, NIS2), education, and B2B companies with sensitive customer or IP data all benefit from a sovereign martech stack.
Get in touch and we'll discuss what this means for your organization.
