Data protection in the cloud – Polish law and data security
Choosing the right model is not only a decision about architecture and costs, but also about protecting information in the cloud and ensuring regulatory compliance.
Choosing the right model is not only a decision about architecture and costs, but also about protecting information in the cloud and ensuring compliance with regulations, especially in the context of Polish law and European regulations. The main focus here is the GDPR, the European Parliament regulation on the protection of personal data, as well as the related legislation in force in Poland. In addition, companies must take industry-specific regulations into account, such as the recommendations of the Polish Financial Supervision Authority for banks and payment institutions, as well as regulations applicable to the healthcare and public administration sectors.
A fundamental requirement of the GDPR is to ensure that personal data is processed only in locations and in a manner that provides an appropriate level of protection. In practice, this means that a company must have a clear understanding of where its servers are physically located and which laws may grant access to them. In the case of large, international public cloud providers, some resources may be located outside the EU, raising additional questions about the legality of data transfers (the so-called Transfer Impact Assessment). Furthermore, U.S. regulations, such as the Cloud Act, theoretically allow U.S. authorities to access data processed by U.S. entities, even if the servers are located in Europe. This represents a significant reputational and legal risk for Polish companies, particularly those storing sensitive data.
Local cloud and hosting providers often offer data centers in Poland, which significantly simplifies jurisdictional issues. Data remains protected by Polish and EU law, and in the event of an inspection, for example by the Personal Data Protection Office, it is easier to provide evidence of compliance with security requirements. It is also important that Polish providers typically employ engineers who are highly familiar with local regulations and can respond quickly in the event of a security incident or when new solutions need to be implemented, such as end-to-end encryption. Technically, this translates into implementing encryption mechanisms for data at rest and in transit, as well as creating access policies based on the principle of least privilege.
In addition to the GDPR, Polish law also imposes obligations related to data retention and the archiving of official documents. Companies in the financial sector must comply with the guidelines of the Polish Financial Supervision Authority, which often makes it impossible to move critical systems abroad without additional audits and approvals. Similar regulations apply to the healthcare sector, where patient data is treated as sensitive information requiring special protection and, in many cases, encryption. For this reason, a private cloud or a service hosted in a Polish data center can often be a significantly safer choice. Even if it is formally possible to use a public cloud provided by major international vendors, local regulations and the need to maintain data sovereignty mean that domestic solutions provide greater legal certainty and enable potential disputes to be resolved more quickly.
An element of security is also the creation of regular backups. Cloud computing, regardless of the model, does not eliminate the need for multilayered data protection. Therefore, solutions such as snapshots, replicas in different geographical locations, and anti-ransomware systems that verify the integrity of encrypted volumes are implemented. Polish law does not directly require the use of any specific backup technology, but in practice, the lack of an effective data recovery strategy can expose a company to significant financial penalties in the event of a data breach or to reputational damage. Therefore, data security depends not only on choosing the right cloud, but also on planning recovery procedures in the event of a failure or cyberattack.
Summary
In an era of constantly growing demand for computing power and storage capacity, every company must consciously define its cloud strategy. Whether a fully public cloud or private solutions provided in cooperation with a local provider will be the better choice depends on the workload profile, regulatory requirements (including Polish law and the GDPR), the required level of security, as well as the organizational culture and competencies of the IT team. Each model has its advantages and disadvantages. The public cloud is attractive due to its simplicity and rapid deployment, the private cloud provides data sovereignty and predictable OPEX following a larger investment in hardware, while the hybrid cloud combines both approaches, although it requires advanced integration and experienced engineers.
The final decision should therefore take into account both technical considerations and long-term financial, legal, and organizational implications. Polish regulations, particularly in regulated sectors such as finance and healthcare, often clearly define the need to keep data within the country, which naturally favors local providers. Equally important, geographical proximity translates into lower latency and better technical support. In the long term, this synergy – local presence, high-quality services, and full legal compliance – may prove to be the foundation for stable and scalable growth for any organization.
