The Ultimate Guide to Data Subject Access Requests (DSAR)

What is a DSAR?

A Data Subject Access Request (DSAR) is a formal request by an individual (data subject) asking an organization for details about the personal data the organization holds about them. Originating primarily from major data privacy regulations like the European Union's GDPR and California's CCPA, DSARs empower individuals with transparency and control over their personal data.

The concept of DSAR emerged strongly in 2018 with the GDPR, reshaping the relationship between businesses and consumers. The GDPR, followed by CCPA and similar global laws, emphasizes the individual's rights to access, rectify, or erase personal data, significantly impacting how organizations manage personal information.

Why DSAR Matters for Organizations

DSAR compliance isn't optional, it's legally mandatory. Non-compliance can lead to:

• Significant Fines: GDPR violations can result in penalties of up to €20 million or 4% of global revenue, whichever is higher.
  
• Customer Attrition: Poor handling of DSARs erodes trust, leading to potential loss of customers.
  

Reputational Damage: Negative publicity from data mishandling can severely harm an organization's reputation and brand value.

Common DSAR Triggers

DSARs often spike following specific events:

• Data Breaches: Individuals request their data to assess the personal impact.
  
  
• Employment Disputes: Employees may file DSARs during disputes or litigation.
  
  
• Increased Privacy Awareness: Proactive users may regularly request their data to ensure compliance and proper handling.
  

The Hidden Cost: Time and Effort

DSAR compliance requires substantial effort from security and compliance teams. Identifying and compiling all relevant personal data across diverse systems—cloud, SaaS applications, and legacy on-premise solutions—is resource-intensive and time-consuming. When an incident such as a data breach occurs, organizations can suddenly face a surge of simultaneous DSARs, further complicating the task. Responding timely and accurately under these circumstances can exhaust compliance teams, risking errors, delayed responses, and potential compliance violations.

Sentra’s DSAR Feature at a Glance

Initiating a DSAR request in Sentra begins with entering all the identifying information we have on the subject of the DSAR request (whose information we need to find).

Selecting Identifiers for DSAR Requests

Selecting the right identifiers is a critical step when handling DSARs (Data Subject Access Requests), as it directly impacts the accuracy, completeness, and performance of the data retrieval process.

Once Sentra has classified your data, the next step is selecting the identifiers you’ll use to submit DSARs. These identifiers must be unique and reliably map to a single individual, such as email addresses, customer IDs, or Social Security Numbers (SSNs).

Avoid using non-unique identifiers like names or physical addresses, as they can match multiple individuals, leading to inaccurate results and slower processing. For example, different people may share the same name or reside at the same address. To ensure accuracy and compliance, non-unique identifiers should be excluded entirely from your DSAR process.

Defining Target Data Stores for DSAR Requests

Before submitting DSARs, it is essential to define which data stores should be included in the search. This is done by enabling DSAR Scans in the Scanning Configuration of the relevant target data stores, such as production databases, file storage systems, or other sources that may contain personal data subject to DSARs.

Sentra will automatically apply the defined scope to all future DSAR requests, ensuring that searches cover all necessary data sources.

To select the data stores, open the data store catalog and click "Enable DSAR Scans" in the scan configuration of the relevant data store.

You can view all the data stores that were selected for DSAR scans from the DSAR page.

Submitting DSAR Requests

DSARs can be submitted through the Sentra UI or programmatically via API.

When creating a request, you must specify the relevant data class used for identification (e.g., Email Address) and provide a list of values to search

Example for a DSAR Request:

‍

Once a DSAR request is submitted, Sentra initiates a dedicated scan batch across all relevant data stores defined as DSAR targets and generates a report upon completion.

The DSAR scan is purpose-built for DSAR use cases - designed to be fast, efficient, and accurate.

Exporting DSAR Results

After all scans associated with a DSAR request have successfully completed, Sentra allows you to export the results in either JSON or CSV format through both the Sentra UI and API.

This export provides a comprehensive record of all locations across structured and unstructured data sources - where the specified identity was detected. The report includes detailed metadata such as data store names, table or file paths, data classifications, and retention policies, enabling organizations to efficiently fulfill access or deletion requests.

Data Removal & Removal Verification

By default, Sentra’s installation does not include permissions to delete customer data from production environments. To implement data deletion effectively, the recommended approach is to leverage Sentra’s API and built-in integrations to trigger customer-managed deletion workflows or cleanup scripts.

Sentra’s DSAR API provides a detailed map of all data locations where personal information related to the subject was identified. This output can be used to power targeted, automated deletion processes, ensuring that only the relevant data is removed.

In addition, Sentra can generate a post-deletion verification report confirming whether the subject’s data has been successfully removed from each source. This verification step is essential for ensuring proper data deletion and is critical for maintaining audit readiness, demonstrating compliance, and confidently closing the DSAR workflow.

Establishing a DSAR Processing Pipeline

Large organizations that handle a high volume of DSAR (Data Subject Access Request) submissions often build a comprehensive, end-to-end processing pipeline to manage them at scale. Below is an overview of how this pipeline is typically structured, and how Sentra plays a key role in automating critical steps.

The process usually begins through a self-service privacy portal, where individuals can easily submit requests to access or delete their personal data. Once submitted, an automated or semi-automated workflow is triggered to ensure timely and compliant handling of the request.

• Requester Identity Verification: Confirm the identity of the data subject to prevent unauthorized access (e.g., via email confirmation or secure login).
  
  
• Mapping Identifiers: Collect and map all known identifiers for the individual across systems (e.g., email, user ID, customer number).
  
  
• Environment-Wide Data Discovery (via Sentra): Use Sentra to search all relevant environments - cloud, SaaS, on-prem for personal data tied to the individual. Sentra’s automated discovery and classification identifies where to search.
  
  
• DSAR Report Generation (via Sentra): Compile a detailed report listing all personal data found and where it resides.
  
  
• Data Deletion & Verification (via Sentra): Remove or anonymize personal data as required, then rerun a search to verify that deletion is complete.
  
  
• Final Response to Requester: Send a confirmation to the requester, outlining the actions taken and officially closing the request.
