What Our Clients Say About Supervisory Authority Engagement Support

We work with organisations navigating complex, high-stakes regulatory situations, from prolonged complaints and DSAR escalations to formal investigations, breach inquiries, and legislative consultations. Our clients include public bodies, healthcare providers, regulated tech companies, and legal teams responding to supervisory authority action across the EU and UK. Whether facing repeated regulator queries, mandated remediation, or GDPR Article 36 consultations, our support is designed to bring clarity, defensibility, and confidence at every stage. Here’s what some of our clients say about working with us:

"We were under sustained scrutiny over a medical data subject complaint that persisted for over two years. XpertDPO helped us handle each regulator query with precision, from redaction defensibility to risk documentation. Their involvement gave us the structure and confidence to manage the entire case calmly, and the matter was ultimately closed without further inquiry."

— Data Protection Officer, Section 39 Organisation

"We approached XpertDPO after our organisation had already received enforcement action and a requirement to prove remediation. Their team helped us systematically rebuild our documentation, correct governance gaps, and prepare regulator-ready evidence of improvement. It was a turning point in re-establishing our compliance posture."

— Head of Compliance, Private Sector

"Our team relied on XpertDPO’s support during a sensitive DPIA that required formal consultation with the supervisory authority. They helped us align our position, address likely risk objections, and engage confidently. We’ve since continued working with them on sector-specific legislative consultations, where their regulator-facing clarity has been invaluable."

Regulatory Response: Choosing the Right Support Model

When a supervisory authority makes contact, whether due to a complaint, data breach, DSAR escalation, or formal investigation, your organisation’s response needs to be accurate, timely, and defensible. But not all support models are built for that pressure.

Internal teams may lack capacity or perspective, while legal counsel can be reactive, costly, and disconnected from operational realities. Effective supervisory authority engagement demands expert guidance, real-time responsiveness, and strategic documentation, all aligned with GDPR obligations and regulator expectations. The table below compares three common response models and shows why leading organisations choose XpertDPO.
