Configure PII scrubbing, GDPR compliance, data retention, and audit controls for Sentry. This skill covers client-side filtering with beforeSend, server-side scrubbing rules, data subject erasure via API, and SOC 2 compliance patterns.
Overview
Sentry captures error context that often contains personally identifiable information (PII) — emails in stack traces, credit card numbers in request bodies, IP addresses in headers. Production deployments must scrub this data at two layers: client-side via beforeSend hooks (before data leaves the application) and server-side via Sentry's built-in Data Scrubber (defense in depth). GDPR requires additional controls: consent-based initialization, data subject deletion endpoints, and a signed Data Processing Agreement. This skill implements all three layers with TypeScript and Python examples, plus verification tests to prove scrubbing works end-to-end.
Prerequisites
Sentry SDK v8 installed and initialized (@sentry/node or sentry-sdk)
Sentry project with Admin or Owner role (required for Security & Privacy settings)
Compliance requirements documented (GDPR, HIPAA, PCI-DSS, or SOC 2)
Auth token with project:write and org:admin scopes for API operations
Step 1 — Client-Side PII Scrubbing with beforeSend
The first defense layer prevents PII from leaving your application. Configure beforeSend, beforeSendTransaction, and beforeBreadcrumb hooks during SDK initialization:
Scrub IP Addresses — enable to remove client IPs from all events
Scrub Credit Cards — detect and remove card number patterns
For advanced regex-based rules, navigate to Project Settings > Security & Privacy > Advanced Data Scrubbing:
# Remove credit card patterns from all string fields
[Remove] [Regex: \d{4}-\d{4}-\d{4}-\d{4}] from [$string]
# Remove email addresses everywhere
[Remove] [Regex: \b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}\b] from [$string]
# Remove SSN patterns
[Remove] [Regex: \b\d{3}-\d{2}-\d{4}\b] from [$string]
# Mask passwords in request bodies
[Mask] [Password] from [extra.request_body]
# Replace credit card data everywhere with placeholder
[Replace] [Credit card] with [REDACTED] from [**]
Data forwarding — if forwarding events to external systems (Splunk, BigQuery), apply the same scrubbing rules at the destination. Configure forwarding in Project Settings > Data Forwarding.
Data retention — configure in Organization Settings > Subscription > Data Retention:

Step 3 — GDPR Compliance and Data Subject Requests
Right to be Informed — document Sentry usage in your privacy policy. Disclose what data is collected (stack traces, device info, anonymized user IDs) and the legal basis (legitimate interest in application reliability).
Consent-based initialization — for strict GDPR compliance, gate Sentry on user consent:
functioninitSentryWithConsent(hasConsent: boolean): void {
if (!hasConsent) {
// Do not initialize Sentry — no data sentreturn;
}
Sentry.init({
dsn: process.env.SENTRY_DSN,
sendDefaultPii: false,
beforeSend: scrubEvent,
});
}
Right to Erasure (Article 17) — delete user data via the Sentry API:
# Delete all events for a specific issue
curl -X DELETE \
-H "Authorization: Bearer ${SENTRY_AUTH_TOKEN}" \
"https://sentry.io/api/0/projects/${SENTRY_ORG}/${SENTRY_PROJECT}/issues/${ISSUE_ID}/" \
|| { echo"ERROR: Deletion failed — verify auth token has project:admin scope"; exit 1; }
// Programmatic deletion for data subject requestsasyncfunctionhandleDeletionRequest(userId: string): Promise<void> {
const org = process.env.SENTRY_ORG;
const project = process.env.SENTRY_PROJECT;
const token = process.env.SENTRY_AUTH_TOKEN;
// Search for issues containing user dataconst searchRes = awaitfetch(
`https://sentry.io/api/0/projects/${org}/${project}/issues/?query=user.id:${userId}`,
{ headers: { Authorization: `Bearer ${token}` } }
);
if (!searchRes.ok) {
thrownewError(`Search failed: ${searchRes.status}${searchRes.statusText}`);
}
const issues = await searchRes.json();
// Delete each matching issuefor (const issue of issues) {
const deleteRes = awaitfetch(
`https://sentry.io/api/0/projects/${org}/${project}/issues/${issue.id}/`,
{ method: 'DELETE', headers: { Authorization: `Bearer ${token}` } }
);
if (!deleteRes.ok) {
thrownewError(`Deletion failed for issue ${issue.id}: ${deleteRes.status}`);
}
}
console.log(`Deleted ${issues.length} issues for user ${userId}`);
}
Audit log access — Business and Enterprise plans provide audit logs at Organization Settings > Audit Log. Export via API for SOC 2 evidence:
