# PIA / DPIA

## What is a PIA / DPIA?

A Data Protection Impact Assessment (DPIA), also known as a Privacy Impact Assessment (PIA), is a process required under Article 35 of the GDPR when a processing activity is likely to result in a high risk to the rights and freedoms of individuals.

A DPIA must be carried out before starting a processing activity that presents such risks, and reviewed whenever the nature of the processing changes significantly.

## Does this processing need a DPIA?

In Dastra, the **Impact assessment** tab of each processing activity helps you determine whether a DPIA is required. It evaluates 9 risk criteria defined by the EDPB:

* Evaluation or scoring including profiling and prediction activities
* Automated decision making with significant effects
* Systematic monitoring
* Sensitive personal data
* Data processed on a large scale
* Combining, linking or cross-referencing data
* Data concerning vulnerable individuals
* Innovative use or application of new technologies
* Processing that prevents data subjects from exercising their rights

For each criterion, select "Yes", "No" or "Not applicable". **Two "Yes" answers are generally sufficient** to trigger a DPIA requirement, though a single criterion may be sufficient depending on context.

{% hint style="info" %}
The list of processing activities requiring a DPIA depends on your national supervisory authority's recommendations. Dastra provides a DPIA Guide with country-specific recommendations to help you identify your obligations.
{% endhint %}

Dastra will display one of two results:

* **"A DPIA is not required"** — the processing does not meet the threshold
* **"You need to carry out a data protection impact assessment (DPIA)"** — a "Create a DPIA" button appears to launch the assessment directly

## PIA / DPIA templates in Dastra

Several PIA/DPIA templates are available in the Dastra library, including:

* **PIA (CNIL) - Privacy Impact Analysis** (57 questions): the standard PIA model from the French data protection authority, for a single processing activity
* **PIA (CNIL) - Privacy Impact Analysis (multi-processing)** (57 questions): the CNIL model adapted for assessments covering multiple processing activities
* **Privacy impact assessment (PIA)** (114 questions): a comprehensive generic PIA template
* **EDPB DPIA Template 2026** (82 questions): the template recommended by the European Data Protection Board
* **DPIA Template for AI Systems** (90 questions): for processing activities involving high-risk AI systems (GDPR + EU AI Act)
* **DPC DPIA Questionnaire - Ireland** (9 questions): the template from the Irish data protection authority
* **DPIA Questionnaire (ICO)** (9 questions): the template from the UK data protection authority
* **US PIA (cross-state)** (86 questions): for US-based processing activities

To access these templates, go to the "Questionnaire templates" tab and click **"Create a template"** → **"Automated questionnaires"**, then filter by type "Privacy impact".

## Structure of the PIA (CNIL) questionnaire

The PIA (CNIL) template is structured around three main parts:

1. **Context** — describe the processing activity: general information, purpose, data involved, stakeholders (controller, processors, joint controllers)
2. **Basic principles** — assess proportionality and data need, and document measures to protect individuals' rights
3. **Risks related to data security** — evaluate risks across four threat categories: security measures implemented, illegitimate access to data, unwanted modification of data, and disappearance of data

{% hint style="info" %}
The PIA (CNIL) questionnaire offers two response modes: **Simple mode** for a streamlined experience, and **Expert mode** for a more detailed assessment. You can switch between modes at any time.
{% endhint %}

## Linking a PIA to a processing activity

To get the most out of the PIA functionality in Dastra, configure your PIA template as follows:

1. Set the **template type** to "Impact analysis" — this enables the risk heat map in the questionnaire dashboard and integrates data from the linked processing activity.
2. In the **Assessed element** section, select "Processing activity" — this links each PIA response to a specific processing activity and automatically updates the last DPIA date upon validation.

{% hint style="info" %}
Once a PIA is linked to a processing activity, you can access it directly from the **"Impact assessment"** tab within that processing activity, and launch it with the "Create a DPIA" button when the threshold is met.
{% endhint %}

## Importing a PIA from the CNIL tool

If you have already conducted a PIA using the CNIL's dedicated tool, you can import it directly into Dastra:

1. Export your PIA from the CNIL tool in **.json format**
2. In Dastra, select the PIA (CNIL) template and click **"Import your CNIL PIA"**
3. A large part of the elements will be automatically imported into Dastra

## Conducting a DPIA on multiple processing activities

A single DPIA may cover several processing activities that are similar in nature, scope, context, purposes and risks. Use the **PIA (CNIL) - Privacy Impact Analysis (multi-processing)** template, or configure your template so that it is **not linked to a specific processing activity**. You can then conduct the DPIA, export it, and attach it to the documentation of the relevant processing activities.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.dastra.eu/en/features/audit/questionnaire-types/pia-dpia.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
