Data Breach? Follow These 6 Crucial Steps
Assess the scope of the breach
Establish which personal data has been exposed, how many people are affected and how the breach happened. This determines every step that follows.
Contain the breach immediately
Act straight away to stop the leak. Shut down vulnerable systems, change passwords and block any unauthorised access.
Document everything carefully
Record what happened, when, which data was affected and what action you are taking. This is a legal requirement and essential for your notification.
Report it to the Dutch Data Protection Authority
You are legally required to report the breach to the Autoriteit Persoonsgegevens (AP) within 72 hours using its online notification form, unless the breach is unlikely to pose a risk.
Inform the people affected
If the breach poses a high risk to the people involved, you must inform them without delay about the breach, its possible consequences and the measures you are taking.
Take preventive measures
Fix the root cause of the breach and put improvements in place to stop it happening again. Review your security policy.

A data breach is one of the most stressful situations a business owner can face. On top of the technical challenge of fixing the breach, you are dealing with legal obligations, potential fines and reputational damage. The GDPR (General Data Protection Regulation) requires you to report a data breach to the Dutch Data Protection Authority within 72 hours, and the clock starts ticking the moment you discover it. Our team understands the urgency and helps you meet every obligation. With the upcoming NIS2 Directive, the requirements for incident reporting and security are becoming even stricter.
Not every security incident is a data breach, but every data breach needs careful handling. A data breach occurs when personal data has been exposed to unauthorised parties, lost or processed unlawfully. That can range from a stolen laptop to a hack of your customer database, or even an email containing personal data sent to the wrong recipient. Our cybersecurity specialists help you classify and handle every incident correctly.
At TRON Group, we take the entire data breach process off your hands. Our incident response team immediately starts containing the breach, carries out a forensic investigation to establish its scope, and helps you prepare and submit the notification to the Dutch Data Protection Authority. We also advise on communicating with the people affected and help you document every step, which the AP requires you to record in your data breach register.
Long-term protection against data breaches
Prevention is better than cure. When you outsource your IT security to TRON Group, you gain access to advanced security measures that stop data breaches before they happen. Think encryption of sensitive data, strict access control, Data Loss Prevention (DLP) tools and continuous monitoring for suspicious activity. Our managed cybersecurity services combine technical security with policy guidance.
We also help you set up a data breach procedure, train your staff to recognise and report incidents, and keep the mandatory data breach register up to date. That way you are not only prepared for a possible breach, you also significantly reduce the chance of one happening.
