ISO 27001 vs DPDP: where one certification actually covers the other
A control-by-control crosswalk for teams tired of answering twice.
20 April 2026 · 9 min read · Dataspace Research
Teams that hold ISO 27001 often assume DPDP is a formality; teams facing DPDP first assume ISO will follow cheaply. Both assumptions fail in the same place: ISO certifies that you manage information security systematically — DPDP regulates what you may do with personal data at all. One is about how well you protect; the other is about whether you were allowed to process in the first place.
Where ISO genuinely carries you
Roughly 60% of DPDP's 'reasonable security safeguards' obligation is satisfied by a well-run ISMS: access control, cryptography, incident management, supplier security, logging. If your Annex A controls are real, your DPDP breach-prevention story is largely written.
Where ISO covers nothing
Consent and lawful basis, purpose limitation, data-principal rights (access, correction, erasure with statutory clocks), children's data, and breach notification to the Board within DPDP's timelines — none of these exist in ISO 27001. No Annex A control produces a consent ledger or answers a DPR in time.
Run them on one answer set
The practical move is a crosswalk: one evidence repository where the ISMS controls feed both frameworks, and the DPDP-only obligations (registers, DPR portal, consent) run as their own workflows. That is precisely the architecture GovernanceOps AI ships — answer once, comply twice.
