A Data Protection Impact Assessment (DPIA) is a mandatory GDPR process for identifying and minimizing privacy risks before high-risk data processing activities begin. Under GDPR Article 35, organizations must complete a DPIA whenever processing is likely to result in a high risk to individuals' rights and freedoms. Your Secure Privacy DPO guides your team through every stage of the assessment — from initial screening to sign-off and ongoing review.
Who Is This For?
Data Protection Officers and privacy managers responsible for GDPR Article 35 compliance
Legal and compliance teams assessing new data processing activities
IT and product teams launching projects that involve personal data processing
Organizations subject to GDPR that process special category data or conduct large-scale profiling
What Is a Data Protection Impact Assessment (DPIA)?
A DPIA is a structured process designed to systematically analyze and minimize the data protection risks of a project or processing activity. Under GDPR Article 35, completing a DPIA is not optional — it is a legal requirement for processing activities that pose a high risk to individuals. Failing to conduct a required DPIA can result in regulatory enforcement action and significant fines.
DPIA Requirements Under GDPR: When Is One Mandatory?
A DPIA is required under GDPR Article 35 when processing is likely to result in a high risk to individuals. This includes, but is not limited to, processing that involves:
Systematic and extensive evaluation of personal aspects through profiling, where decisions produce significant effects on individuals
Large-scale processing of special categories of personal data (e.g., health, biometric, or criminal offense data)
Systematic monitoring of publicly accessible areas on a large scale (e.g., CCTV)
Any processing activity included on your supervisory authority's published list of operations requiring a DPIA
When in doubt, your DPO can conduct a pre-screening assessment to determine whether a full DPIA is needed.
The DPIA Process: Step-by-Step
Your Secure Privacy DPO guides your organization through a structured, seven-stage DPIA process:
Screening: Determine whether a DPIA is required for the proposed processing activity.
Description: Document the nature, scope, context, and purposes of the processing in full.
Necessity assessment: Evaluate whether the processing is necessary and proportionate to its stated purpose.
Risk identification: Identify specific risks to the rights and freedoms of data subjects arising from the processing.
Risk mitigation: Define technical and organizational measures to address and reduce identified risks.
Sign-off: The DPO provides formal written advice and the completed assessment is approved by the data controller.
Review: Schedule ongoing reviews to keep the DPIA current as the processing activity evolves over time.
GDPR Article 35(7) DPIA Contents: What Must Be Included
GDPR Article 35(7) specifies the minimum required contents of a valid DPIA. Your Secure Privacy DPO ensures all four elements are fully addressed:
Requirement |
Description |
|---|---|
Processing Description |
A systematic description of the envisaged processing operations and their purposes, including the legitimate interest pursued where applicable |
Necessity Assessment |
An assessment of the necessity and proportionality of the processing in relation to its purpose |
Risk Assessment |
An assessment of the risks to the rights and freedoms of data subjects, including likelihood and severity |
Mitigation Measures |
The measures envisaged to address identified risks and demonstrate GDPR compliance, including safeguards and security measures |
How Your Secure Privacy DPO Supports the DPIA Process
Your Secure Privacy DPO provides expert guidance at every stage of the DPIA lifecycle. This includes reviewing completed assessments for completeness and legal sufficiency, advising on the adequacy of proposed mitigation measures, and determining whether the residual risk is acceptable for processing to proceed.
Where residual risk remains high after mitigation, your DPO will advise on whether prior consultation with the supervisory authority is required under GDPR Article 36 — a step that is mandatory if the risk cannot be sufficiently reduced by the data controller alone.
Frequently Asked Questions
What happens if an organization fails to conduct a required DPIA?
Failing to carry out a mandatory DPIA is a direct violation of GDPR Article 35 and can result in regulatory enforcement action, including fines of up to €10 million or 2% of global annual turnover under GDPR Article 83(4).
Who is responsible for approving a completed DPIA?
The data controller is responsible for approving the DPIA. The DPO provides formal written advice as part of the sign-off process but does not bear personal liability for the controller's processing decisions. Where disagreement exists, the DPO's advice and the controller's reasoning must both be documented.
Does a DPIA need to be repeated?
Yes. DPIAs are not one-time documents. GDPR requires organizations to review a DPIA when the processing activity changes or when there is reason to believe the risk level has shifted. Your DPO will help schedule and manage periodic reviews.
When is prior consultation with a supervisory authority required after a DPIA?
Under GDPR Article 36, prior consultation with the relevant supervisory authority is required when the DPIA indicates that high residual risk cannot be adequately mitigated by the organization alone. Your DPO will assess this and manage the consultation process on your behalf if needed.
