The secure processing of personal data is one of the central challenges for companies today—in Europe as well as globally. With advancing digitalisation, responsibility is also growing: IT managers, CISOs, and compliance teams must guarantee the protection of sensitive information.
The General Data Protection Regulation (GDPR) has formed the legal framework since 2018. From 12 September 2025, additional obligations come into force with the EU Data Act. Providers of cloud services and digital platforms are particularly affected. Among other things, they must grant users access to their generated data, facilitate switching to other providers, and revise their contractual terms accordingly.
However, data protection is far more than a legal must: implemented consistently and in compliance with regulations, it becomes a genuine competitive advantage. In this article, we show you what matters when implementing current data protection regulations, which measures have proven successful, and how i-doit can provide support.
Data protection is the protective shield in the digital space: it prevents personal data from falling into the wrong hands or being lost. Various measures are used for this purpose. Their common goal: to process data only for clearly defined and legally permissible purposes—with full transparency and control.
Both technical and organisational measures are used here:
Companies that clearly structure their data processes, document specifications, and regularly train employees not only safeguard legal certainty but also strengthen the trust of their target groups. A comprehensive IT documentation solution like i-doit supports companies in managing all relevant information in a GDPR-compliant manner.
The GDPR has been applicable since 25 May 2018 and sets uniform requirements across Europe for handling personal data. Companies are obliged to provide data subjects with information about stored data, delete this data upon request, and ensure transparent processing workflows.
By introducing structured workflows, not only can legal requirements be met, but processes can also be improved. The ISMS practical guide from i-doit offers practically orientated advice on implementation.
Although data protection and data security pursue a common goal—the protection of sensitive data—they differ in their focus:
Example: Consent to data processing is a requirement under data protection law. Encryption during storage, on the other hand, is a data security measure.
Only through the interaction of both areas does effective protection for personal data arise. An Information Security Management System (ISMS) combines the legal and technical requirements—and helps companies to implement the specifications of the GDPR in a structured way.
Companies must comply with several core principles when processing data:
Compliance with these principles reduces risks and strengthens trust. A structured IT documentation solution like i-doit helps to implement these requirements.
The data protection officer (DPO) primarily ensures that a company consistently implements data protection regulations. Furthermore, they organise training sessions for employees and serve as a point of contact both internally and externally. Good to know: for those who regularly process personal or particularly sensitive data, the appointment of a data protection officer is required by law.
The overarching challenges of a data protection officer include, among others:
In addition to the data protection officer, IT administrators must also keep an eye on the topic of data protection. You can find more on this in our article "IT Administrators and Liability".
It is evident: data protection is more complex for companies today than ever before. The combination of constantly growing data volumes, hybrid IT structures, and strict legal regulations complicates the implementation of effective protective measures.
Added to this is the human component: carelessness, weak passwords, or communication errors frequently lead to data protection violations. AI systems also require early consideration of data protection issues. Documentation obligations, impact assessments, and the explainability of processes must be observed.
The introduction of the EU AI Act also brings new challenges. Anyone using AI systems bears a special responsibility: the handling of personal data must comply with data protection regulations at all times. Alongside extensive documentation obligations, additional requirements apply, particularly to automated decisions. These include:
For sensitive data or high-risk AI systems, these measures are mandatory. The fundamental takeaway is that AI projects must be designed in a data-protection-compliant manner from the very beginning to avoid data protection violations, fines, or reputational damage.
The EU Data Act obliges companies to enable access to user-generated data both technically and contractually. This applies in particular to providers of cloud and platform services. It is necessary to provide standardised interfaces and fully inform users about their rights. Companies should review and adapt their data processing contracts now.
Practical example: Data protection in a medium-sized company
A medium-sized IT service company uses i-doit to efficiently manage its own infrastructure. In the process, systems, responsibilities, access controls, and deletion periods are centrally recorded and documented. Through the integration of the i-doit Data Privacy Add-on, compliance with the GDPR is continuously reviewed and adjusted as necessary. Requests for information from data subjects can thus be answered within the shortest possible time.
Tips and checklist for data protection within the framework of the ISMS:
Carry out risk assessments regularly.
Document measures in a catalogue of measures.
Control access rights on a role-based basis and check them regularly.
Centrally record and evaluate security incidents.
These points support the identification and targeted remediation of vulnerabilities. With i-doit, all relevant data can be managed centrally and in a structured manner.
Further proven procedures:
Conduct a thorough data inventory.
Define policies for data storage and access.
Implement technical protection with current security standards (e.g. Zero Trust).
Train all parties involved.
Use PETs (Privacy Enhancing Technologies) such as differential privacy or zero-knowledge proofs.
With a solution like i-doit, organisational and technical requirements can be mapped centrally.
Customers and partners are increasingly paying attention to transparency. Data protection authorities are monitoring more proactively in advance and imposing sensitive sanctions in the event of violations. With i-doit, you can document your measures traceably and implement them in a legally secure manner. Responsible persons, departments, and service providers can be assigned to all devices, applications, and other assets.
Collaboration between the IT department and the data protection officer (DPO) also benefits. The DPO is usually an external person or a separate department within the company. They should only receive the information relevant to the assets. This can be controlled very granularly via the rights system of i-doit, enabling seamless collaboration.
Modern consent management, an overview of processing procedures, audit-proof documentation: i-doit offers the appropriate tools for GDPR-compliant data processing. Thei-doit VIVA2 Add-on was developed for the implementation of IT-Grundschutz. It supports compliance with legal specifications. You can get an insight into how you fulfil your documentation obligations in our video.
Data protection is a complex but important task for any company. More and more data is operationally relevant and worthy of protection. Even when processing is carried out by third parties, companies must guarantee high data security. Only in this way do they comply with the requirements of the GDPR and the EU Data Act and protect the data subjects.
With the right strategies, training, and tools, organisations fulfil GDPR requirements—and win the trust of their customers along the way. Responsible handling of data speaks volumes for a company.
