When selecting a vendor, businesses often focus on pricing, service capability, implementation experience, and commercial terms. While these are important criteria, for vendors that access or process personal data, assessing business capability alone is not sufficient.
A vendor may be commercially strong yet still pose significant compliance risks if the business does not clearly understand what data the vendor will access, at what scale, through which tools, and under what level of internal control. In practice, many data-related risks do not arise during contract execution, but from the vendor selection stage—when the right questions have not yet been asked.
Privacy due diligence does not need to be overly complex. At a minimum, businesses should establish a dedicated review layer to assess the scope of data processing, the level of dependency on the vendor, access control capabilities, and key contractual safeguards before any data is shared.
A practical tip for IT and Procurement teams:
Businesses should incorporate a privacy due diligence checklist into the vendor onboarding process for any services involving personal data.
Mini-checklist:
Determine whether the vendor will access or process personal data;
Clarify the types of data, volume of data, and processing purposes;
Review the vendor’s data storage, access, and technical support model;
Assess the need for specific privacy clauses in the contract;
Require internal approval before transferring data to the vendor.
In many cases, effective personal data control does not begin with a signed contract—it begins with the questions a business asks before deciding to engage a vendor.
Legal reference:
Law on Personal Data Protection No. 91/2025/QH15 and its implementing regulations, particularly provisions on the roles of parties in data processing, responsibilities for ensuring data security, and control over data sharing with third parties.
