Will your small business be fined for reporting a data breach?

Many entrepreneurs worry that reporting a data breach will automatically lead to an investigation or a hefty fine, but it’s not the case. Regulators understand that incidents happen. What they want to see is that your business took reasonable steps to protect personal data and acted responsibly when a problem was discovered.

Key takeaways:

• Spain's data protection authority received 2,765 data breach notifications in 2025, but only 11 cases were referred for investigation.
• Reporting a data breach is a legal obligation under GDPR in certain situations and is often viewed as a sign of responsibility.
• Regulators focus more on whether a business acted responsibly than on whether a breach occurred.
• Common causes of data breaches include stolen credentials, lack of multi-factor authentication (MFA), human error, and system misconfigurations.
• Simple security measures such as MFA, strong passwords, employee training, and software updates can significantly reduce risk.
• Having a response plan in place can help your business recover faster and demonstrate compliance if a breach occurs.

A data breach doesn't automatically lead to a fine. Poor data protection might.

According to the Spanish Data Protection Agency, 2,765 personal data breaches were reported in 2025. Around 80% of these incidents came from private organizations, while the remaining 20% involved public institutions. More than 200 million notifications were sent to people whose information may have been exposed in breaches considered high-risk. Despite the large number of incidents, only 11 cases were referred for further investigation.

For small business owners, that's an important distinction. The data suggests that regulators understand breaches can happen, even to organizations that take security seriously. Their focus is not simply on whether a breach occurred, but on how the organization handled personal data before and after the incident.

In other words, the biggest risk isn't necessarily experiencing a breach. It's failing to take reasonable steps to protect customer, employee, and business information in the first place.

What regulators want to see after a data breach

Under GDPR, organizations are required to notify authorities when a breach poses a risk to people's rights and freedoms. Reporting shows that a business is taking its responsibilities seriously and acting transparently when something goes wrong.

This isn't unique to Spain. Across Europe, data protection authorities understand that no business can prevent every cyberattack, human mistake, or security incident. What they want to see is that organizations have made a genuine effort to protect personal data and respond appropriately when problems occur.

The Spanish Data Protection Agency has made it clear that its focus is not on punishing organizations that report incidents. Instead, attention is typically directed at cases where there are signs of negligence or failure to meet basic data protection obligations.

What regulators consider poor data protection practices

 It often comes down to whether basic security measures were in place before the breach happened. They're practical steps that help reduce risk and demonstrate that your business takes data protection seriously. For example, regulators may ask questions such as:

• Were business accounts protected with multi-factor authentication?
• Were software and operating systems kept up to date?
• Did employees use their own accounts instead of sharing passwords?
• Did staff have access only to the information they needed?
• Was there a process for identifying and reporting suspicious activity?
• Were customer and employee records stored securely?

The most common causes of data breaches

Many serious data breaches are caused by simple, preventable mistakes. According to the Spanish Data Protection Agency, one of the most common causes was the use of compromised credentials combined with the lack of multi-factor authentication (MFA). Attackers gained access through stolen usernames and passwords, particularly in services exposed to the internet or used for remote access.

Human error also played a significant role. Common mistakes included:

• Sending personal information to the wrong recipient
• Accidentally publishing sensitive data
• Incorrectly configuring systems or online services
• Giving employees access to information they didn't need for their role

8 ways to reduce the risk of a data breach

Improving your security doesn't require an enterprise-sized budget or an IT department. For most small businesses, a few sensible precautions can significantly reduce risk.

1. Enable multi-factor authentication wherever possible. Many of the serious breaches reported in Spain involved compromised credentials. Multi-factor authentication (MFA) adds an extra layer of protection if a password is stolen or leaked.

2. Use strong and unique passwords. Reusing passwords across multiple accounts can allow attackers to gain access to several systems from a single compromised login. A password manager can help employees create and store unique passwords securely.

3. Keep software and devices updated. Cybercriminals often exploit known vulnerabilities that already have available security fixes. Regular updates help close those gaps before attackers can take advantage of them.

4. Protect every device used for work. Business data lives on multiple devices. Office computers, laptops, smartphones, and tablets often contain customer information, emails, contracts, and business documents that should be protected.

5. Help employees recognize scams and phishing attempts. One click on a convincing phishing email can expose credentials or sensitive information. Even a small team can benefit from basic security awareness training.

6. Limit access to sensitive information. Not every employee needs access to every file, customer record, or system. Restricting access reduces the risk of accidental exposure and limits the damage if an account is compromised.

7. Back up important business data regularly. Backups can help your business recover more quickly from ransomware attacks, accidental deletion, or other incidents that affect critical information.

8. Use security tools designed for small businesses. Security software can help identify malware, block phishing attacks, monitor for suspicious activity, and protect business devices without requiring dedicated IT staff.

FAQs

Do I have to report a data breach under GDPR?

The severity and potential impact of the incident will determine whether reporting is required.

Will I automatically receive a fine if I report a data breach?

No. Reporting a data breach does not automatically lead to a fine or investigation. As the Spanish Data Protection Agency's 2025 figures show, thousands of breaches were reported, but only a small number were referred for further investigation. Regulators are often more interested in whether a business acted responsibly than in the fact that a breach occurred.

What do regulators look for after a data breach?

Authorities typically look at whether a business took reasonable steps to protect personal data before the incident and how it responded afterward. This may include reviewing security measures, access controls, software updates, employee practices, and the organization's breach response process.

What is considered a lack of diligence in data protection?

A lack of diligence can include failing to implement basic security measures such as multi-factor authentication, using weak passwords, neglecting software updates, allowing employees to share accounts, or storing sensitive information without appropriate safeguards.

What are the most common causes of data breaches?

Common causes include stolen or compromised credentials, lack of multi-factor authentication, phishing attacks, human error, accidental disclosure of information, and incorrectly configured systems or services.

How can small businesses reduce the risk of a data breach?

Small businesses can reduce risk by enabling multi-factor authentication, using strong and unique passwords, keeping software updated, limiting access to sensitive information, training employees to recognize scams, backing up data regularly, and using cybersecurity tools designed for small businesses.

What should I do if my business experiences a data breach?

If you suspect a breach, secure affected systems, determine what information may have been exposed, document the incident, assess the impact, notify authorities if required, inform affected individuals when necessary, and review your security practices to prevent similar incidents in the future.
