“Good software is not an accident—it comes from a structured development process with clear quality standards.”

*January 2026 *

In an more often digitized world where data are the new gold, the protection of personal data is more often focused.

The General Data Protection Regulation (GDPR) has created a strict legal framework for this in Europe.

A central concept that companies need to take into account in the development of software and IT systems is "Privacy by Design".

But what is exactly behind it and why is it essential for a DSGVO compliant software?

What is Privacy by Design?

Privacy by Design, i.e. "Data protection through technology design", is an approach in which data protection is integrated from the start into the development of products and services.

Instead of considering data protection as a subsequent supplement, it becomes a core part of the entire development process.

The aim is to act preventively and prevent data breaches before they can arise at all.

This proactive approach was built by Dr. Ann Cavoukian, a leading Canadian data protection expert, and is based on seven basic principles.

The 7 basic principles of Privacy by Design

In an more often digitized world where data are the new gold, the protection of personal data is more often focused.

If Privacy by Design: GDPR from the start is on your roadmap, IT Security und Discover solutions outline services and next steps.

These principles serve as a guide for the development of data protection-friendly technologies and processes. They help anchor the data protection deeply in the system architecture.

Principle Description
1. Proactive, non-reactive; preventive, non-responsive Data protection measures are introduced foresight to prevent data protection incidents instead of responding to them.
2. Data protection as a default setting (Privacy by Default) Systems are configured from the outset to provide the highest level of data protection. The user does not have to become active himself to protect his data.
3. embedded data protection Data protection is an integral part of the system and its architecture, no subsequent supplement.
4. Full features – positive sum, not zero sum Data protection and security are not considered as opposites. The aim is to safeguard both the interests of users and the features of the system.
5. End-to-end security – protection over the entire life cycle Personal data is protected across their entire life cycle – from collection to deletion.
6. Visibility and clarity – true openness The data processing processes are transparent and comprehensible for users. You know what data is being processed and why.
7. Respect for the privacy of users – user centering User interests and rights are at the centre of attention. The systems are user-friendly and provide users with control options about their data.

Practical next steps after Privacy by Design: GDPR from the start

Privacy by Design: GDPR from the start addresses a practical choice for product and IT teams. Start with one clear goal: align software scope, technical risk, and business value before the next investment.

Check the current process, the data involved, and the result users need. Then record the main risks and define a small first step. This keeps the decision easy to review and gives your team a shared basis.
