PII Found on the Web: How It Affects Your DSAR Obligations

When Exposed PII Meets DSARs

If personal data you hold is found exposed on the web — through a misconfigured database, a vendor breach, or an accidental upload — expect DSARs to follow. People who learn their data was exposed often exercise their access and deletion rights immediately.

Why Exposed PII Triggers DSARs

When personal data appears publicly, affected individuals want to know:

• What data do you hold about me? (access request)
• Where did you share my data? (third-party disclosure request)
• Delete everything you have on me. (erasure/deletion request)
• How did this happen? (not a formal DSAR, but often included in the same message)

After a breach notification, DSAR volume can spike 5-10x within the first two weeks. If you normally get one request per month, a breach can generate dozens at once.

The Breach-DSAR Overlap

Breach response and DSAR fulfillment are separate obligations that run on different clocks:

• Breach notification — GDPR: 72 hours to supervisory authority. US state laws: varies (30-60 days typically). These are about telling people what happened.
• DSAR response — GDPR: 30 days. CCPA: 45 days. These are about providing or deleting the data itself.

Both clocks start independently. A breach does not pause your DSAR deadlines, and a DSAR does not satisfy your breach notification obligations.

How to Handle Post-Breach DSARs

1. Triage Incoming Requests

Not every message after a breach is a formal DSAR. Sort incoming communications:

• Formal DSARs — requests to access, delete, or correct personal data. These have legal deadlines.
• Breach inquiries — questions about what happened, whether their data was affected. Handle through your breach communication process.
• Combined — a message that asks both "what happened?" and "delete my data." Treat the DSAR portion formally.

2. Acknowledge Quickly

Send acknowledgments immediately. When people are anxious about exposed data, silence makes it worse. Your acknowledgment should:

• Confirm you received the request
• State the type of request (access, deletion, etc.)
• Provide your response deadline
• Reference your breach notification if applicable

3. Use Your Data Map

If you built a data map before the breach, now is when it pays off. You already know which systems hold personal data and how to search them.

If you do not have a data map, start with the systems involved in the breach and expand from there. See our data discovery guide.

4. Batch Where Possible

If you receive many similar requests (e.g., 50 people all asking you to delete their data), you can process them as a batch:

• Same search across the same systems
• Same deletion workflow
• Individual responses to each requester

Batching the work is fine. Sending a single response to multiple people is not — each requester gets their own response.

5. Do Not Conflate Breach Notifications with DSAR Responses

Your breach notification letter is not a DSAR response. If someone submits a DSAR, they need a separate, specific response that covers their personal data — not a generic "we experienced a breach" message.

Access Requests After a Breach

When someone submits an access request after learning their data was exposed, they typically want to understand the full scope. Your response should include:

• All personal data you hold about them (same as any access request)
• Categories of recipients their data was shared with
• If asked, confirmation of whether their data was part of the breach

You do not need to provide forensic details about the breach itself in a DSAR response. Stick to what data you hold and who received it.

Deletion Requests After a Breach

Deletion requests spike after breaches. Handle them normally, but watch for:

• Data you must retain — legal holds, regulatory requirements, or contractual obligations may prevent deletion of some data, even after a breach
• Data needed for breach investigation — you may need to retain certain records until the investigation is complete
• Third-party copies — if the exposed data was shared with vendors or partners, your deletion obligations may extend to them

Communicate clearly about any data you cannot delete and why.

Reducing Future Exposure

The best way to limit post-breach DSARs is to reduce the data you hold:

• Data minimization — collect and retain only what you need
• Regular purging — delete data you no longer need before it gets exposed
• Access controls — limit who can access personal data and how

Less data stored means less data exposed, which means fewer DSARs to process.
