These questions keep deal work connected to material risk, transfer evidence, vendor exposure and post-close control. [Read the full FAQ](https://xpertdpo.com/faq/) What is data protection due diligence in M&A? Data protection due diligence reviews the target’s personal data, systems, vendors, transfer position, policies, incidents, DSARs, records and governance evidence. The aim is to identify privacy risks that may affect deal confidence, warranties, remediation, integration or post-close control. What kind of privacy risks can due diligence identify? Common risks include unclear controller or processor roles, weak records, unresolved incidents, poor DSAR handling, missing DPIAs, fragile vendor evidence, transfer gaps, retention issues, insecure systems, weak training records and privacy obligations that may affect integration. Can you help with international data transfer risks in due diligence? Yes. Transfer review may include data flows, group access, vendors, sub-processors, support locations, safeguards, SCCs, TIAs, onward transfers and unresolved evidence gaps. Transfer work should connect contract position to operational reality. How do vendor and processor risks connect to DPIAs? Vendor and processor facts often affect the risk assessment: roles, data categories, access, retention, security, sub-processing, transfers, AI features, telemetry and model updates. DPIA work should not sit separately from vendor evidence where the vendor is part of the processing. Next step ## Start with the work that now needs confidence.
