Data Diets: Shedding Excess for a Leaner, Safer 2025
17 Feb

The digital landscape continues to evolve, with businesses increasingly reliant on data to operate effectively and initiate growth. However, as we head into 2025 and with the increasingly widespread use of AI and other tools to analyse data, it’s crucial to reassess how data (and particularly personal data) is managed. The concept of a “data diet” — trimming unnecessary data, improving security, and staying compliant with privacy laws — should be an integral part of business operations, creating efficiency, enhancing customer trust, and mitigating risks.
Why a Data Diet?
Data storage often seems unlimited and so streamlining data is sometimes not given any thought. However, keeping hold of old or unnecessary information can be expensive and risky. From a legal perspective, excessive or poorly managed data retention opens businesses to the risk of liability under the General Data Protection Regulation (GDPR), the UK GDPR, and other similar privacy laws, which could result in significant fines.
Having strong data retentions policies has an added benefit of leaner data systems, improving efficiency, and allowing businesses to respond faster to customer needs, all whilst reducing operational costs.
Key Steps for a Data Diet
1. Conduct a Data Audit:
Start with a comprehensive review of stored data. Categorise information based on relevance and necessity, and make sure personal data is clearly designated. Outdated or duplicated records should be securely deleted, freeing up resources and reducing exposure in case of a breach.
2. Update Privacy Policies and Contracts:
Ensure your agreements with employees, customers, and third-party providers are up-to-date. Provisions should clearly define personal data usage, ownership, and security obligations, reflecting current legal standards. This also includes having a data retention policy, for both internal management and training purposes, and also for external comms – as data subjects have a right to know how long you keep their data for.
3. Implement Stronger Cybersecurity Measures:
Cyber threats are becoming more sophisticated. Businesses should adopt:
- Encryption for data in transit and storage.
- Multi-factor authentication for access to sensitive systems.
- Regular penetration testing to identify and address vulnerabilities.
This ensures security of the data you actually choose to retain.
4. Train Staff:
Human error remains a leading cause of data breaches. Regular training ensures employees understand their role in protecting the personal data that you hold, and making sure they aren’t retaining data that isn’t needed, leading to unnecessary risk.
