We support financial services firms from initial assessment through the creation of records of processing activities to audit-ready documentation of technical and organisational measures.
The General Data Protection Regulation presents banks and financial service providers with unique challenges due to complex customer data processing, cross-border data transfers, and strict regulatory requirements. Successful GDPR compliance in the banking sector requires more than standardized data protection approaches — it requires specialized banking expertise that smoothly connects data protection law with financial regulation. We develop tailored GDPR banking frameworks that not only ensure legal compliance but also increase operational efficiency, strengthen customer trust, and establish sustainable competitive advantages through superior data protection governance in the financial sector.
The General Data Protection Regulation places complex requirements on cloud computing environments through cross-border data transfer compliance, cloud provider due diligence, data residency requirements and multi-cloud governance structures for secure cloud data processing.

We develop tailored transfer frameworks that not only meet regulatory requirements but also enable strategic international business opportunities, minimize risks, and establish sustainable competitive advantages through superior cross-border governance and international data protection excellence.
The General Data Protection Regulation (GDPR) requires systematic and sustainable implementation. We support you in the complete fulfillment of all data protection requirements.
Insurance companies process particularly sensitive personal data — from health data and creditworthiness information to risk profiles. The GDPR therefore imposes stringent requirements on the insurance sector: legal bases under Art. 6 and Art. 9, consent management, data protection impact assessments for scoring and profiling, and deletion concepts that account for insurance-specific retention obligations. We advise insurers on the practical implementation of all GDPR obligations — legally compliant, efficient and aligned with industry-specific regulations such as codes of conduct under Art. 40 GDPR and national insurance supervision requirements.
Ensure continuous compliance with GDPR requirements through our comprehensive ongoing compliance approach. We establish data protection governance structures, automated monitoring mechanisms, and proactive adaptation processes that guarantee lasting compliance and sustainably minimize data protection risks.
The General Data Protection Regulation places complex demands on Privacy-by-Design implementation through proactive privacy protection, privacy-as-default settings, privacy-embedded design, and full-functionality privacy balance for sustainable data protection governance. Successful GDPR Privacy-by-Design management goes beyond traditional compliance approaches and creates integrated privacy systems that smoothly connect privacy engineering, data minimization, and user privacy rights. We develop tailored Privacy-by-Design frameworks that not only meet regulatory requirements but also enable strategic business innovation, minimize privacy risks, and establish sustainable competitive advantages through superior privacy governance and data protection excellence.
A professional GDPR readiness assessment reveals where your organisation stands on data protection. We evaluate your current maturity level, uncover compliance gaps, and develop a prioritised roadmap to full GDPR conformity.
GDPR Article 28 requires controllers to engage only processors that provide sufficient guarantees for appropriate technical and organisational measures. A legally sound data processing agreement (DPA) governs the subject matter, duration, purpose and security measures of data processing. ADVISORI supports you in selecting and assessing processors, drafting your DPA and establishing ongoing monitoring – practical, legally compliant and efficient.
Frequently Asked Questions about GDPR Data Breach Response
When must a data breach be notified under Article 33 GDPR?
A personal data breach must be notified to the supervisory authority when it is likely to result in a risk to the rights and freedoms of natural persons. The notification must be made without undue delay and, where feasible, within
72 hours of becoming aware of the breach. If the 72-hour deadline cannot be met, the delay must be explained. No notification is required if the breach is unlikely to pose a risk to individuals — for example, when encrypted data was accessed but could not be decrypted.
What information must a data breach notification to the supervisory authority contain?
The notification must describe the nature of the breach, state the categories and approximate number of affected individuals and data records, provide the data protection officer as a contact point, describe the likely consequences of the breach, and outline the measures taken or proposed to address it. Where it is not possible to provide all information at once, it may be provided in phases without undue further delay.
When must affected individuals be notified under Article 34 GDPR?
Affected individuals must be notified when the data breach is likely to result in a high risk to their rights and freedoms. The notification must use clear and plain language, describing the nature of the breach, the contact point, the likely consequences and the measures taken. Notification is not required if appropriate safeguards such as encryption were in place, or if subsequent measures have eliminated the high risk.
What fines apply for late or missing data breach notifications under GDPR?
Failure to comply with the notification obligation under Article
33 GDPR can result in fines of up to EUR
10 million or 2% of global annual turnover. Additional violations of the individual notification requirement under Article
34 can lead to fines of up to EUR
20 million or 4% of annual turnover. The fine amount depends on the nature and severity of the violation, its duration, the number of affected individuals and the degree of cooperation with the supervisory authority.
What does an incident response process for a data breach look like?
A structured incident response process consists of six steps: detection of the incident through technical monitoring or employee reporting, initial assessment to evaluate the notification obligation, containment of the breach through immediate technical and organisational measures, notification to the supervisory authority within
72 hours, communication with affected individuals where there is high risk, and post-incident review including root cause analysis and improvement of protective measures.
What are typical examples of notifiable data breaches under GDPR?
Notifiable breaches include sending customer data to the wrong recipients, loss of unencrypted laptops or USB drives containing personal data, ransomware attacks with access to customer databases, misconfigured cloud storage with public access to personal data, and phishing attacks gaining access to email accounts containing personal data. Whether notification is required depends on the risk assessment in each individual case.
What is the role of the data processor in a personal data breach?
Data processors must notify the controller without undue delay after becoming aware of a personal data breach. The notification obligation to the supervisory authority lies with the controller, not the processor. The processing agreement under Article
28 GDPR should include clear provisions on notification deadlines, information obligations and the support the processor must provide during a data breach.
