Your enterprise customers ask where their data lives. We explain what your infrastructure choice contributes to KVKK compliance, where it stops and which technical controls help.
If you are a SaaS company selling to enterprise customers in Türkiye, you will meet the same question in every security questionnaire: where is our data stored? In this post we look at why data residency matters, what your choice of infrastructure does and does not solve, and the technical controls you can put in place.
This post is for general information and is not legal advice. We recommend getting an opinion from legal counsel for your own situation.
Law No. 6698 on the Protection of Personal Data (KVKK) sets conditions for processing personal data and for transferring it abroad. Enterprise customers, especially in regulated industries such as finance, healthcare and the public sector, ask how their suppliers meet these conditions.
Keeping data in Türkiye simplifies a large share of these questions. Procurement moves faster, and you can give clearer answers in security reviews.
KVKK has two key roles: data controller and data processor. A SaaS company usually plays both:
This distinction directly shapes your contracts, your privacy notices and your relationship with your infrastructure provider.
Running on infrastructure in Türkiye answers the question of where data physically lives and reduces uncertainty around cross-border transfers. But compliance is not only about infrastructure. Access controls in your application, logging, retention and deletion processes, privacy notices and contracts remain your responsibility.
In short, the right infrastructure is a solid foundation for your compliance work, not the whole of it.
Bulutlan Edge Cloud serves from the İstanbul and Konya regions in Türkiye. According to our infrastructure partner RNG Technology, these data centers are in different geographies and are Tier 3+ certified, and the Edge Cloud services are delivered as fully KVKK compliant cloud infrastructure services.
Your region choice determines where your data lives. When you choose a Türkiye region, your data stays within Türkiye. You can also use both Türkiye regions together to build an active-active architecture.
With Multi-Tenancy, you can open a fully isolated project for each enterprise customer. VPSA technology provides storage dedicated to your business on the public cloud, isolated even at the physical layer.
Businesses can use their own SSL certificates and create their own keys with AES-256. Keeping the key under your control is a requirement that often comes up in security reviews.
On Edge Cloud, you can assign detailed role-based permissions to projects and use multi-factor authentication. Bulutlan Console requires two-factor authentication at every sign-in.
Object Storage offers immutable storage, versioning and encryption. Backing up data from flash storage directly to Object Storage adds another layer of protection against ransomware and deliberate attacks.
According to RNG Technology, physical disks can be handed over to the customer after the service ends, on request. That gives your customers a concrete answer about data disposal at the end of a contract.
However well the infrastructure is protected, personal data often leaks at the application layer. Watch out for these points:
Technical controls are not enough on their own; you also need to document them. When working with enterprise customers, these documents usually come up:
Remember that backups fall under data residency too. If you keep your backups in Türkiye regions, your answer stays consistent there as well.
In security questionnaires, you can answer these topics clearly:
For SaaS companies selling to enterprise customers in Türkiye, data residency is no longer a preference but part of the sales process. See For SaaS Companies for more, or review your architecture with one of our experts.
