TL;DR: Manual DSAR handling breaks down as personal data spreads across cloud, SaaS, on-prem, and unstructured systems, making discovery, identity matching, and deadline management slow and error-prone, according to Sentra. The governance issue is not just compliance throughput but whether privacy, identity, and data controls can produce complete responses without exposing or omitting personal data.
NHIMG editorial — based on content published by Sentra: DSAR automation and why privacy response is hard to scale
By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
Questions worth separating out
Q: What breaks when DSAR requests depend on manual identity matching?
A: Manual matching breaks when one person appears under different identifiers across systems, because teams cannot reliably assemble complete records within privacy deadlines.
Q: Why do distributed data environments make DSAR compliance harder?
A: Distributed environments increase the number of systems that must be searched, validated, and documented, which raises the chance of missed records and slow responses.
Q: What do organisations get wrong about DSAR automation?
A: They often automate intake before they automate traceability.
Practitioner guidance
- Map DSAR workflows to authoritative identity sources Link requester verification and record matching to the same authoritative identity and account sources used elsewhere in the identity programme so that multiple identifiers resolve consistently.
- Scope search paths to known data-holding systems Limit automated discovery to systems already mapped as likely repositories of personal data, including cloud, SaaS, on-prem, and approved unstructured stores.
- Require post-deletion verification scans Run a follow-up search after deletion or anonymisation to confirm that personal data has actually been removed and that duplicates or shadow copies remain absent.

DSAR automation is fundamentally an identity and data governance problem, not a form-filling problem. The article shows that response quality depends on linking a requester to records across multiple systems, which is an identity resolution task before it is a privacy task. That means IAM, privacy, and data security teams need shared control points for verification, mapping, and auditability. Practitioners should treat DSAR workflow design as part of the broader identity governance programme.
A question worth separating out:
Q: Who is accountable when a DSAR response is incomplete or late?
A: Accountability usually sits with the organisation’s privacy leadership, but the root cause often spans IAM, data ownership, legal review, and platform operations. The practical model is shared accountability with clear system ownership, because no single team can fix discovery gaps, identity mismatches, and response timing alone.
