‘Reactive’ and ‘data protection’ are two phrases no organisation wants to have sitting near each other. But with data protection teams facing more compliance pressure than ever, and cyber threats evolving constantly, how can adopting a ‘data protection by design’ approach help organisations move to — and sustain — a proactive approach to data protection?

What is Data Protection by Design?

Data Protection by Design and by Default is a proactive approach to protecting personal data, and is one of the foundational principles of UK and EU data protection law. Rather than bolting on privacy safeguards after a system, product or process has already been built, it requires that protection is designed in from the outset — and that the most privacy-friendly settings apply by default.

The key principles of data protection by design

1. Proactive, not reactive; preventive, not remedial
Instead of waiting for privacy issues to arise and then addressing them, data protection by design emphasises anticipating and preventing data risks before they occur. This approach embeds controls and safeguards throughout the entire lifecycle of data processing activities.

2. Data protection as the default setting
Organisations should ensure personal data is automatically protected by default. The default settings for any system or process should be the most privacy-friendly options, minimising data collection, processing and retention to what is strictly necessary.

3. Data protection embedded into design
Privacy and data protection features should be integrated into the design and architecture of IT systems and business practices, rather than added on as an afterthought. Protecting data should be an integral part of the core functionality of any system or process.

4. Full functionality — positive-sum, not zero-sum
Data protection by design promotes a win-win approach, where privacy and other legitimate interests and objectives are both accommodated and enhanced. This principle rejects the notion that privacy must be sacrificed for other functionality.

5. End-to-end security — lifecycle protection
Strong security measures should be in place throughout the entire lifecycle of the data, from collection to deletion. This includes encryption, secure storage and controlled access, so personal data stays protected at every stage.

6. Visibility and transparency
Organisations should be transparent about their data processing practices, ensuring individuals understand how their data is being used and protected — through clear communication, comprehensive privacy policies, and mechanisms for people to exercise their data rights.

7. Respect for user privacy — keep it user-centric
Data protection by design means designing systems and processes that prioritise user privacy, provide people with control over their data, and make it straightforward to exercise rights such as access, correction and deletion.

The role of the Data Protection Officer

Applying these principles across an entire organisation is, in practice, the job of the Data Protection Officer (DPO) — a role that has grown significantly in importance over the past decade as organisations have become more data-driven. For many organisations the DPO position is mandated by Articles 37, 38 and 39 of GDPR regulations. Alongside advising on privacy, DPOs must ensure the organisation can evidence compliance and doesn’t fall foul of GDPR’s transparency, accountability and accuracy requirements. In the event of a serious incident, data breach or complaint, the DPO acts for the data subject and as an intermediary with the regulator — in the UK, the Information Commissioner’s Office (ICO).

Why one person can’t own this alone

‘Data protection by design and default’ is a fundamental requirement of UK GDPR. It requires a risk assessment of data protection and processing activities at the conception and design stage of any project, throughout its lifecycle, and whenever procedures, data sources or processor contracts change.

For the DPO, implementing this across multiple departments and countless systems is difficult — they’re rarely close enough to every specific system to embed protection by design into it directly. Too many organisations treat the DPO as the sole first line of defence for personal data, even though the DPO doesn’t own the underlying data or the procedures that generate it. Given the range of threats and the specific complexities within each department, one individual sitting above every function with a generalised approach isn’t an effective model.

Turning to Data Champions

Instead, organisations should devolve responsibility for data protection to ‘Data Champions’ within each department, so the people who actually own the data are the first line of defence. This puts specific expertise and knowledge of departmental systems and processes where it’s needed, and equips departments to build in data protection by design themselves when change happens — while the DPO remains in an advisory capacity.

Data Champions are more likely to spot vulnerabilities that a DPO sitting above every function would miss. The DPO’s role remains critical — they’re still ultimately responsible for providing advice — but responsibility for personal data sits with the specific touchpoints and individual departments that generate it. The Data Champion’s closer understanding of their department’s need for personal data, how it’s used, and how it can be protected by default, is what makes data protection by design and by default achievable in practice, not just in policy.

How ProvePrivacy helps

Introducing Data Champions works best alongside supporting technology. ProvePrivacy gives DPOs and Data Champions a single platform to build a Record of Processing Activities, gain a holistic view of data across the organisation, and more simply monitor and manage data protection day to day. Identifying data protection risks, maintaining policies and procedures, and giving colleagues training to understand the threats and vulnerabilities they need to design against, can all be done in one place — demonstrating that your organisation has the technical and organisational measures to support data protection by design.
