The sovereignty audit of your martech stack: 7 questions you should be asking yourself
The discussion around digital sovereignty is becoming increasingly concrete. The coalition agreement makes digital autonomy a guiding principle. NIS2 sets stricter requirements. And the reality of the CLOUD Act is reaching more and more boardrooms. But one domain is consistently forgotten: your marketing technology stack.
Your CMS, analytics, email marketing, forms, personalization engine, DAM — together they form the digital nervous system of your organization. They process customer data, visitor behavior, lead information, and sometimes medical or financial data. And a large portion of those tools is American.
Below are seven questions to ask yourself. Not a theoretical exercise, but a practical audit you can do in about an hour.
Where is my CMS vendor's headquarters located?
The location of your servers is less relevant than the location of your vendor's headquarters. An American company with servers in Frankfurt still falls under the CLOUD Act. This applies to the big names — but also to many smaller SaaS tools you might overlook.
What data does each tool process — and how sensitive is it?
Not all tools carry the same risk. Your CMS with public content is different from your marketing automation platform that processes names, emails, behavioral data, and possibly even segmentation data. Map out per tool what type of data it processes and assess the sensitivity.
Do I have an exit strategy if I want to switch vendors?
Vendor lock-in is a sovereignty risk in itself. If your content is stuck in a proprietary format, if your data is not exportable, or if your integrations depend on a single platform — then your autonomy is limited, even if the vendor is European.
What do my data processing agreements say about jurisdiction?
Most organizations have signed data processing agreements, but few have carefully read the clauses on international data transfers and legal jurisdiction. Specifically: is there a clause stating the vendor can comply with foreign government orders?
What happens to my data if the geopolitical situation changes?
The EU-US Data Privacy Framework is the third agreement in a series — after Safe Harbor and Privacy Shield, both of which were struck down by the European Court of Justice. A fourth revision is not unthinkable. What if your data suddenly falls into a legal vacuum?
Are there European alternatives that are functionally on par?
This is the question many organizations answer with "no" too quickly. The European martech market is more mature than you think. Plate CMS offers a fully Dutch-hosted CMS. Prepr combines headless CMS with personalization. Spotler delivers email marketing, automation, and a CDP from Rotterdam. Piwik PRO is already used by the Dutch government.
Who in my organization is responsible for this consideration?
Digital sovereignty doesn't fit neatly into one box. It's not a purely IT topic (it touches marketing and customer data), not a purely legal topic (it requires technical knowledge), and not a purely marketing topic (it has compliance implications). The organizations that get it right appoint a multidisciplinary team.
A sovereign martech stack is not an ideal scenario. It is a concrete plan with European vendors that are functionally on par, implemented step by step, and continuously monitored.
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.
