Data breach notification in India: the DPDPA’s 72-hour timeline and beyond

A personal data breach under the DPDPA triggers a two-stage notification obligation: intimation to the Data Protection Board and the affected Data Principals “without delay,” followed by a detailed report within 72 hours. This sits alongside—not in replacement of—the CERT-In six-hour cyber-incident reporting requirement under the IT Act. Organisations must run both tracks simultaneously.

Short answer

Section 8(6) of the DPDPA requires a Data Fiduciary to intimate the Data Protection Board and the affected Data Principals about a personal data breach, without delay. Rule 7 requires a detailed report to the Board within 72 hours. Non-notification carries a penalty ceiling of up to ₹200 crore, as determined by the Board after inquiry. The CERT-In Directions (April 2022) separately require reporting of specified cyber-security incidents to CERT-In within six hours—this runs in parallel with the DPDPA obligation.

The two-stage notification process

Section 8(6) creates the obligation; Rule 7 provides the procedure:

  1. 01

    Stage 1: Intimation without delay

    The Data Fiduciary must intimate the Data Protection Board and each affected Data Principal about the breach as soon as it becomes aware of it. “Without delay” means without unreasonable delay—the clock starts when the organisation has credible evidence of a breach, not when the forensic investigation is complete.

  2. 02

    Stage 2: Detailed report within 72 hours

    Rule 7 requires a detailed report to the Board within 72 hours. The report must describe the nature of the breach, the categories and approximate number of Data Principals affected, the likely consequences, the measures taken or proposed to address the breach and to mitigate its effects.

CERT-In parallel obligation: six-hour reporting

The Indian Computer Emergency Response Team (CERT-In) Directions issued in April 2022 under the IT Act 2000 require organisations to report specified cyber-security incidents to CERT-In within six hours of noticing or being brought to notice of the incident. “Specified incidents” include data breaches, ransomware attacks, phishing and unauthorised access.

The CERT-In six-hour clock and the DPDPA 72-hour clock run in parallel—they are separate obligations under different statutes. A personal data breach that is also a cyber-security incident must be reported to both CERT-In (within 6 hours) and the Data Protection Board (detailed report within 72 hours). Compliance with one does not satisfy the other.

What the detailed report must contain

Rule 7 specifies the content of the detailed breach report to the Board:

  • Nature and circumstances of the personal data breach
  • Categories of personal data affected (e.g. identity data, financial data, health data)
  • Approximate number of Data Principals affected
  • Likely consequences of the breach for the affected Data Principals
  • Measures taken or proposed to address the breach
  • Measures taken or proposed to mitigate the adverse effects on Data Principals
  • Contact details of the Data Protection Officer or other point of contact

Penalties for non-notification

The DPDPA Schedule sets the penalty ceiling for non-compliance with Section 8(6) at up to ₹200 crore, as determined by the Data Protection Board after inquiry. Section 33(2) lists the factors the Board considers: the nature, gravity and duration of the breach; whether the Data Fiduciary took prompt action to mitigate; whether there was a pattern of contravention; and any gain made or loss avoided.

Separately, failure to implement the security safeguards that should have prevented the breach (Section 8(5)) carries a ceiling of up to ₹250 crore. In a breach scenario, both provisions may be engaged—the Board can assess the security failure and the notification failure independently.

Bottom line

Breach notification is a two-track obligation: DPDPA (intimation without delay + 72-hour report) and CERT-In (6 hours). Both run in parallel. Prepare the playbook before the breach happens.

Questions and answers

Data Breach Notification: common questions

What is the deadline for notifying the Data Protection Board of a breach?

Section 8(6) requires intimation “without delay.” Rule 7 requires a detailed report within 72 hours. The initial intimation should be sent as soon as the organisation has credible evidence of a breach.

Do I also need to report to CERT-In?

Yes, if the breach is a cyber-security incident. The CERT-In Directions (April 2022) require reporting within six hours. This runs in parallel with the DPDPA 72-hour obligation—compliance with one does not satisfy the other.

What is the penalty for failing to notify a breach?

Up to ₹200 crore for non-compliance with Section 8(6), as determined by the Board after inquiry. Additionally, up to ₹250 crore may apply for inadequate security safeguards under Section 8(5) if those contributed to the breach.

Must I notify each affected Data Principal individually?

Section 8(6) requires intimation to each affected Data Principal. The method of intimation is not specified—email, SMS, in-app notification or postal mail may be appropriate depending on the context and the Data Principal’s contact details.
