DPDP / DPIA

Data Protection Impact Assessment

CA Nikhil Gupta·May 2026·3 min readDPDP / DPIA

Use a DPIA to assess high-risk processing, affected people, necessity, alternatives, security, vendor risk, residual harm and launch conditions.

A DPIA should influence product design before launch, not merely document decisions already made.

Quick View

Decision

Trigger formal review when processing is large-scale, sensitive, intrusive, automated, child-focused or difficult for users to understand or avoid.

First action

Create DPIA trigger questionnaire.

Core evidence

DPIA request.

Main warning

DPIA after deployment.

Why It Matters

The Digital Personal Data Protection Act, 2023 and the final Rules notified in November 2025 follow phased commencement. As of 25 June 2026, organisations should separate duties already operative from consent, grievance, rights, children, Significant Data Fiduciary and other operational provisions scheduled for later commencement, while continuing to comply with the IT Act, CERT-In directions and sector-specific rules already in force.

Section 10 specifically requires periodic DPIAs for Significant Data Fiduciaries when the relevant provisions commence, but other organisations can use DPIAs as a governance control for high-risk projects.

A useful DPIA describes the purpose, data, people, systems, decisions, benefits, harms, mitigations, residual risk, approvals and review date.

Action Checklist

  1. Create DPIA trigger questionnaire.
  2. Map the full data flow.
  3. Consult security and affected business teams.
  4. Test less intrusive alternatives.
  5. Approve residual risk formally.
  6. Review after material changes or incidents.

Practical Example

An employer proposes continuous webcam monitoring for remote staff without testing whether output-based controls would achieve the same purpose with less intrusion.

Evidence to Keep

  • DPIA request.
  • Data-flow and architecture diagram.
  • Risk and necessity analysis.
  • Alternative options.
  • Approval minutes.
  • Post-launch review.

Warning Signs

  • DPIA after deployment.
  • No user-impact analysis.
  • Risk scored by product team alone.
  • No stop-launch authority.
  • No review after vendor change.

Detailed Review

A reliable control should connect the individual, data field, purpose, notice or sector disclosure, system, employee access, vendor access, retention rule and closure evidence. A policy statement that cannot be traced through this chain is difficult to operate.

Maintain a legal-timing matrix. Record the DPDP provision, phased commencement status, current IT Act or sectoral duty, business owner, system dependency and implementation deadline. Avoid one blanket label such as compliant or not compliant.

Build controls into technology and workflow. A written instruction cannot stop an SDK from collecting contacts, a campaign tool from re-importing suppressed users or an agent from downloading medical records unless the system enforces the decision.

Use proportionate verification. Weak checks can expose another person’s information; excessive checks create more Aadhaar, health, payroll or bank data that must be protected and deleted later.

Generate evidence during ordinary operations: versioned screens, event logs, access approvals, vendor tickets, complaint chronology, deletion reports, test recordings and management decisions.

Run a negative-path test: refusal, withdrawal, account closure, vendor breach, employee exit or child-user flow. The control should continue to protect data outside the happy path.

Management reporting should show overdue actions, repeat complaints, failed tests and residual risk rather than only the publication of policies.

Control Test

Select one real user or transaction journey and trace it from collection through sharing, access, retention, withdrawal, complaint or closure. Capture the evidence at each stage.

Test the control on production-like systems rather than screenshots alone. Review network traffic, event logs, suppression status, vendor responses, role access and deletion output.

Run an adverse scenario: the vendor is breached, the user is a child, the borrower alleges harassment, the employee leaves or the app permission is revoked. Record the response and gaps.

Compare public wording with actual behaviour. Product forms, call scripts, privacy notices, contracts, SDKs and support tools should tell the same story.

Assign a named owner, funded action and closure date to each gap. Retain the reason when management accepts residual risk or chooses a less intrusive alternative.

Escalation Route

Start with the privacy, security, product or regulated-business owner and preserve system evidence before changing configuration or deleting records. Separate current sector and CERT-In obligations from future DPDP readiness.

For serious complaints, children’s data, financial harassment, medical exposure or suspected cybercrime, involve qualified legal, privacy, cyber, banking, insurance or healthcare specialists and use the applicable official channel.

Frequently Asked Questions

Is DPIA mandatory for every company? â–¼
The Act mandates it for SDFs; others may use it as a prudent risk control.
When should it start? â–¼
During design, before irreversible technical or contractual commitments.
Can a DPIA approve unlawful processing? â–¼
No. It does not replace legal compliance.
Who approves residual risk? â–¼
A senior accountable owner with legal, privacy, security and business input.
