EU data residency and ecommerce platform selection

[u/Shuuuuaib]

We're in the middle of selecting an ecommerce platform for a European operation and our DPO has flagged EU data residency as a hard requirement (not just a configuration preference), and the platforms we're evaluating have meaningfully different answers to where customer data and session tokens actually sit.

The issue holding up our processor agreement review is that some platforms treat EU-region deployment as a configuration layer on top of a US-origin controller, which means signing SCCs, while others are built with EU-resident controllers from the ground up, and the compliance review looks quite different depending on which side of that line a platform sits on.

Our DPO flagged Scayle and Spryker as the 2 EU-native options on our list, both built out of Germany and structuring their DPAs with EU-resident controllers by default, and said those were the ones she could review most straightforwardly without needing SCC negotiations on top.

We'd assumed the EU hosting question was just about picking the right region setting, but where the platform company is incorporated turned out to be the harder constraint to satisfy, and it's not something you find in the standard sales deck.

We don't deal with EU residency often so I can't speak to those platforms specifically, but the controller location thing is a much bigger deal than people think. Everyone focuses on the servers and misses that the legal entity processing the data is what actually drives the SCC requirement. Your DPO is doing the right thing by shortlisting platforms where that's not even a question.

Fire that DPO. Why be even more strict than the GDPR.

cause under the US Cloud act their agencies can ask any US firm for data located in Europe at any point, and have direct access to the data.

US prosecutors can even attach secrecy orders to their demands, so the US firm can't tell you that they gave out your info for up to a year. Microsoft stated this in a transparency report , in second half of 2025 it received 1823 (!) secrecy orders!

Yes? So? Common for most organisation its a non issue.

Define incorporated in this context?

Isn’t this more simply put as only do business with companies that have a fully fledged EU legal entity?

[u/Alert-Shirt-4377]

Hey, I’m a fractional DPO for retailers and I would second your DPO’s opinion. It’s the contracting party’s residence that is most important in minimising the compliance burden on your company. It might feel painful now but in the long run it will make a substantial difference

It's a lot more complicated than this - sorry to challenge you DPO's assessement but EU data residency is not a requirement in the GDPR's article 45 and after.

The requirement is to have a a valid *transfer *mecanism (SCC beeing one of them) - and not the data localisation at all.

So you have 2 ways forward -> you DPO has a real hard reason to make that statement - he needs to justify that very precisely from legal standpoint. The reason I point this out is that a lot of DPO do not have any sort of real training and they unfortunatly they just repeat what facebook forums tell them (at best).

If you DPO is a well trained lawyer (because this is actually a legal question) - and is able to legally state exactly why he put data localisation as requirement and not the transfer mecanism first - AND he can articulate a really good legal reason with detailed legal argument - than ok he has a case.

This point is very important because you might select processors that are located in europe - and unfortunatly for europe - the level of maturity for large software is just not in par with the hyperscalers in the US. You can find - you can read OVH's data center that ended up all burning with all their customer's data and backups as a good reminder of that :

So generally speaking US solutions from hyperscalers are more mature and constitute better solution, despite the art. 47's transfer. DPF + SCC are needed in that case. We all know that the DPF has structural weaknesses but that's been the case forever and US/EU are not going to stop doing business.

Also one thing - you should not spend any time reading or negociating the SCC - the processor should use the standard SCC from EU commission, if they don't it's already kind of an issue.

Why is your DPO issuing hard requirements? Their job is to advise, not decide. They should be explaining legal requirements, not making policy decisions.

And I do not understand what you mean by an EU-resident controller. If your goal is to be a merchant operating an e-commerce website, you are the controller. Your contractors and suppliers that would be supplying the e-commerce setup would be processors.

Data residency usually means where the data is physically located. For GDPR purposes, that is a consideration but people often think it's a bigger deal than it is. From a legal point of view, the country of registration of your processor is the primary determinator of what you need to do.

It is prudent to avoid US based processors, because the US adequacy decision is at risk, and if it falls, it will be difficult to get a good result in a TIA (the SCCs by themselves are not sufficient). That's why I am sympathetic to EU sovereign setups and prefer them myself. But your DPO should not be making that call.
