How Data Processors Can Get You Fined: Vetting Vendors Before They Undermine Your Compliance

When people talk about GDPR, they often focus on what happens inside their own business, what data is collected, how it is stored, and whether consent is captured properly. But one of the most common and dangerous sources of risk comes from outside: the third party vendors, tools and platforms that process data on your behalf.

Most startups and growth stage businesses run on a stack of integrations. CRMs. Email platforms. Chat widgets. Analytics. Payment systems. Automation tools. Each one makes life easier. But each one is a legal relationship under GDPR. And if one of those providers mishandles data, you are the one on the hook.

That is the reality of Article 28 of the GDPR. If you use a data processor, you are responsible for ensuring they comply. Not just by trusting their homepage, but by actively vetting, reviewing and documenting the relationship.

Why This Matters More Than Ever

Enforcement is increasing. Regulators are no longer focusing only on massive data breaches or major brands. They are going after the fundamentals, especially when it comes to international data transfers, unvetted analytics platforms, or shadow integrations added by marketing teams.

A single analytics script, CRM field, or third party plugin that processes user data without proper protection or contractual alignment can result in a formal investigation. Fines aside, it means damaged trust, compliance audits, and time spent fixing problems rather than growing.

How I Vet Vendors for GDPR Risk

I take a structured, practical approach when integrating third party tools. It begins with understanding what the tool actually does, not just what it claims.

First, I review what personal data is collected. Many tools collect more than they disclose. Session replay tools, for instance, may capture input fields unless properly configured. Email tools may scrape user behaviour without any visible signal to the user.

Then, I identify where the data is processed and stored. Is it within the EEA? If not, what safeguards are in place, standard contractual clauses, data protection agreements, or an EU based proxy?

I also look at whether the provider is classified as a controller or processor, and whether they make claims that shift responsibility onto the client. This is common with US based platforms that include vague language in their terms of service.

Finally, I ask: does this vendor make it easy to comply with data subject rights? Can you export, delete, and access user data across their system without friction? If not, that is a warning sign.

Common Risk Areas

In my audits, these are the categories that most often cause problems:

  • Chat tools that store full message transcripts without proper consent or data processing agreements
  • Analytics platforms that log IP addresses or device fingerprints without lawful basis
  • Email platforms that send behavioural data back to ad platforms without user knowledge
  • CRM tools that sync with third party systems but do not mirror deletion requests

Often, these tools are installed or authorised without full review, especially in early stage teams where speed takes priority. But GDPR does not distinguish between deliberate and accidental non compliance. If your processor fails, the legal responsibility still sits with you.

What I Do When a Vendor Is Not Compliant

If a tool fails to meet compliance requirements, I either:

  • Replace it with an alternative that offers proper contracts and EEA data processing
  • Use a proxy or middleware to strip sensitive data before it reaches the processor
  • Segment usage so that only certain user types are affected (for example, excluding EU traffic from the tool)

Sometimes I work directly with the vendor to request a data protection agreement or confirm their data handling in writing. Many providers are willing to do this, but you have to ask.

Due Diligence Is a Growth Function

This is not just a legal issue. It is a growth issue. If your data is not trustworthy, you cannot segment properly. You cannot automate effectively. You cannot build long term relationships with customers who might one day request access or deletion.

I treat vendor selection as part of the growth stack design. Not because I want to slow things down, but because I want to build systems that scale without being torn down later.

Compliance is not a blocker. It is a filter. It helps you choose tools that are built to last. It helps you build trust without saying a word. And it protects the data that drives everything else.

If you are plugging in tools without reading the terms, or relying on integrations that have not been reviewed in years, you are carrying invisible risk.

I help teams reduce that risk. I do the due diligence. I rewrite the processes. I configure tools so they work legally and reliably. Because growth without trust is growth on borrowed time.
