Data protection vs data privacy: what every business needs to know  

Data breaches are already happening at scale for most organisations. In 2024, more than 1.7 billion victim notices were issued globally. In the UK, 43% of businesses experienced a cyber breach or attack, and the cost of failure is rising fast.

Despite the urgency, many organisations still mix up two key parts of a strong security strategy: data protection and data privacy. Knowing the difference and how they work together is essential for building a resilient, compliant, and trustworthy organisation.

What is data protection, and why is it important?   

Data protection keeps sensitive data private, available, and accurate, helping prevent corruption, loss, or unauthorised access. As organisations create and store more data, strong protection has become essential for every business.

The consequences of inadequate protection are severe. In 2025, 43% of organisations were affected by a breach, and the average time to identify and contain a data breach across an organisation is nearly 300 days.

The main goal of data protection is to keep sensitive information secure, easily accessible, and reliable to maintain business operations and build trust with customers, partners, and regulators.

FDM Head of Privacy, Katrina Gallagher, shares, “Data protection has evolved from a compliance exercise into a core business risk because the impact of getting it wrong now extends well beyond regulatory fines. It affects customer trust, brand reputation, operational resilience and, increasingly, the ability to adopt new technologies such as AI. As a result, privacy is now closely aligned with cyber security, enterprise risk and governance functions, and is rightly being discussed at the board level.”

What are data protection principles?   

Data protection principles ensure data remains safe and available at all times, including during backups, business disruptions, and disasters. These principles guide how organisations design and use their tools and processes.

Data availability   

Authorised users must be able to access the data they need, even during an incident. Availability is a basic business need, not just a security issue, because downtime can hurt both finances and reputation.

Data lifecycle management   

Effective data lifecycle management ensures that information is stored, moved, and removed at the right time. By automatically shifting data between storage services and deleting what is no longer needed, organisations can reduce risk while maintaining efficiency.

Information lifecycle management   

This method organises, tracks, and protects information from failures and threats. It makes sure the right safeguards are in place for as long as the information exists.

On average, it takes about 276 days to identify and contain a breach.

What is data privacy, and why is it important?   

Data privacy sets the rules for collecting and handling sensitive data. It includes protection of personally identifiable information (PII) and personal health information (PHI), such as financial records, medical data, ID numbers, names, birthdates, and contact details.

This information supports business operations, development, and finances, so privacy is important for both business and legal reasons.

It ensures that only authorised people can access sensitive data, helps prevent misuse, and supports compliance with regulations.

What are data protection regulations?   

Data protection regulations set the rules for the collection, sharing, and use of certain types of data. The rules for handling personal and sensitive user data can vary widely by country, region, or industry.

The EU’s General Data Protection Regulation (GDPR), in force since 2018, remains the global benchmark. In the UK, organisations operate under UK GDPR post-Brexit and face fines of up to £17.5 million for non-compliance.

Katerina believes, “One of the most common challenges organisations face is navigating multi-jurisdictional requirements. Attempting to treat compliance as a tick-box exercise across different regulatory regimes often leads to fragmented controls and inconsistent practices. The more effective approach is to implement a unified governance framework, supported by clear principles such as data minimisation, accountability and privacy by design, with local variations managed through jurisdiction-specific overlays rather than entirely separate processes.”

Data protection vs data privacy   

The distinction is important: data privacy decides who can access data and under what conditions—it’s the policy layer. Data protection is the operational layer that enforces those policies in practice. Privacy is the blueprint; protection, the construction.

Neither is sufficient without the other. Privacy guidelines alone can’t prevent unauthorised access. Equally, strong data protection can restrict access but leave users without meaningful rights over their own information. Both are essential for genuine security and compliance.

Control is another key difference. Users usually decide what data they share for privacy reasons, which is their right. Companies must ensure data is protected, which is their responsibility. Compliance rules reflect this split in duties.

12 best practices to protect your data   

It’s one thing to know the principles, but putting them into practice is another challenge. Here are the best practices that support a strong data protection strategy.

1. Data discovery   

You can’t protect data if you don’t know it exists. Data discovery is the first step: finding out what sensitive information you have, where it’s stored, and how it moves through your organisation. Automated tools like Big ID can scan and classify data, helping you maintain an accurate, up-to-date inventory.

2. Data loss prevention (DLP)   

DLP technologies watch how data moves and can flag or block any attempts to transfer sensitive information without permission. When used alongside clear policies and automated fixes, they are a key defence against both external threats and internal risks.

3. Secure storage with built-in protection   

Modern storage solutions include features like redundancy, error correction, and detailed access controls. Choosing the right storage setup, especially for highly sensitive data, is an important decision. More organisations are now using immutable storage, which stops data from being changed after it’s saved. This is a strong defence against ransomware.

4. Backup and recovery   

Regular, tested backups remain one of the best ways to prevent data loss and fight ransomware. The 3-2-1 rule is still important: keep three copies of your data, on two types of media, with one copy stored off-site. It’s also vital to protect your backup systems, because if ransomware infects them, recovery can be almost impossible.

5. Snapshots and versioning   

Point-in-time snapshots let organisations quickly restore systems after an incident, with little data loss. Versioning lets you revert to earlier versions, which is especially helpful if ransomware or data corruption is discovered later.

6. Replication and geographical redundancy   

Copying data to multiple locations, ideally across different regions, protects against local outages and system failures. This setup allows for quick switching if main systems go down and helps balance the load to avoid overloads.

7. Firewalls and network security   

Firewalls remain a foundational control, acting as a barrier between internal systems and external threats. Modern next-generation firewalls incorporate intrusion detection and prevention, application control, and advanced traffic monitoring.

8. Authentication and access control   

Multi-factor authentication (MFA), role-based access control (RBAC), and identity and access management (IAM) systems all help ensure that only the right people can access sensitive data, and only as much as their jobs require. Research shows that 60% of breaches involved a direct human element.

9. Encryption   

Encryption keeps data safe whether it’s being sent or stored. Organisations should use symmetric, asymmetric, or end-to-end encryption based on the sensitivity of the data and how it will be used. Encryption is especially important for data moving between systems or stored in the cloud.

10. Endpoint protection   

Now that hybrid working is common in most industries, endpoint security is more important than ever. Antivirus and anti-malware tools, device management systems, and regular updates all help reduce the risk of attacks on company devices. In 2024, 46% of hacked enterprise systems were unmanaged devices.

11. Data erasure   

When data is no longer needed, it should be securely deleted. This can be done by overwriting, erasing or physically destroying the hardware, making sure sensitive information can’t be recovered. Having clear data destruction policies and regular checks ensures this process is followed every time.

12. Disaster recovery planning   

A disaster recovery plan explains how an organisation will respond if something goes wrong. It should be based on a business impact analysis, tested regularly with practice exercises, and updated as new threats appear.

According to Katrina, “In practice, the most common gaps in data protection implementation are not a lack of policies, but a failure to operationalise them. This includes unclear ownership of data, poor data mapping, inconsistent retention practices, and limited integration with business processes. Organisations that recover quickly from incidents tend to have strong governance structures, clear accountability, tested response plans and good visibility over their data estate. Those that struggle often lack these fundamentals.”

Conclusion 

Data protection and data privacy work together; neither is sufficient on its own. With breaches happening everywhere, stricter regulations, and higher costs for mistakes, organisations can’t afford to treat these issues as minor concerns.

A well-designed and well-implemented strategy not only reduces risk but also builds trust with customers, partners, and regulators. This trust can become a real competitive advantage.
