Significant Data Fiduciary (SDF) Readiness, DPIA & Audit under the DPDP Act

The DPDP Act creates a higher tier of obligations for organisations designated Significant Data Fiduciaries (SDFs). While no entity has yet been notified as an SDF, large platforms and high-volume or high-sensitivity processors should expect to be brought within scope as the DPDP Rules, 2025 commence. Preparing early is prudent because the SDF obligations are demanding. This page explains them and how KSK helps clients get ready.

What makes a business an SDF?

Under Section 10(1), the Central Government may designate a data fiduciary or class of fiduciaries as significant, weighing the volume and sensitivity of personal data processed; the risk to data principals’ rights; the potential impact on India’s sovereignty and integrity; the risk to electoral democracy; the security of the State; and public order. Our detailed analysis is here: Significant Data Fiduciaries: enhanced compliance obligations.

The enhanced obligations

Under Section 10(2) and Rule 13 of the DPDP Rules, 2025, an SDF must:

  • Appoint an India-based Data Protection Officer responsible to the board.
  • Appoint an independent data auditor.
  • Conduct a Data Protection Impact Assessment and audit every 12 months and report significant observations to the Board. See our guide to DPIAs and to record-keeping and audit.
  • Carry out algorithmic due diligence — verifying that software, including algorithms, does not pose risks to data principals’ rights.
  • Observe any data-localisation directions the Government issues for specified categories of personal data.

How KSK helps

We help organisations assess their likelihood of SDF designation and build the programme an SDF needs: governance and DPO frameworks, DPIA methodology and execution, audit readiness and auditor coordination, algorithmic and AI-governance review, cross-border data-transfer mapping against sectoral localisation rules, and board-level reporting. The aim is a defensible, documented compliance posture before designation rather than after.

Frequently Asked Questions

DPDP Act — quick answers

What is a Significant Data Fiduciary under the DPDP Act?
It is a data fiduciary, or class of fiduciaries, that the Central Government notifies as significant under Section 10 because of the higher risk its processing poses — typically large platforms and high-volume or high-sensitivity processors. SDFs carry enhanced obligations beyond ordinary data fiduciaries.
What extra obligations do SDFs have?
Under Section 10(2) and Rule 13, an SDF must appoint an India-based DPO and an independent data auditor, conduct a DPIA and audit every 12 months, carry out due diligence on its algorithmic software, and observe any data-localisation directions the Government issues.
Have any companies been designated SDFs yet?
As of 2026, no entity or class has been notified as a Significant Data Fiduciary, and the obligations are subject to the DPDP Rules' phased commencement expected around mid-2027. Businesses likely to qualify should prepare in advance and confirm status against the latest MeitY notifications.
Do SDFs face data-localisation requirements?
The DPDP Act does not impose general data localisation, but Rule 13 allows the Government to bar offshore transfer of specified categories of personal data for SDFs. Sector-specific localisation rules from regulators such as the RBI also continue to apply.
