One Compliance Programme for GDPR and DPDP Together

Running GDPR and DPDP compliance as two separate programmes is the most expensive way to satisfy both. The frameworks share enough structural DNA, consent, data minimisation, individual rights, breach notification, processor contracts, security safeguards,  that a well-designed unified programme covers the majority of both simultaneously. 

The gaps that require separate treatment are real but narrow: DPDP's no-threshold breach notification, its absence of a legitimate interests basis, its Grievance Redress Officer requirement, and the consent notice language obligations for Indian users. Build the unified programme correctly and the marginal cost of DPDP compliance on top of GDPR is a fraction of running two parallel programmes.

Here is how to structure that unified programme, where the shared controls live, and where you need dedicated tracks for each framework.

The Shared Foundation: What Carries Across Both Frameworks

Start with what does not need to be built twice. A functioning GDPR compliance programme already produces most of the structural components DPDP requires.

Data mapping and processing records: GDPR Article 30 requires a Record of Processing Activities covering what personal data is collected, why, where it goes, and how long it is retained. DPDP requires the same understanding, purpose, means, retention, and erasure to build compliant consent notices and manage data principal rights. The data map built for GDPR is the starting point for DPDP, not a separate exercise.

Consent infrastructure: GDPR requires freely given, specific, informed, and unambiguous consent with genuine withdrawal capability. DPDP requires the same standard. The consent flows your product already runs for EU users meet DPDP's baseline consent standard. The gaps, standalone notice format, 22-language availability for Indian users are additions to existing consent architecture, not replacements of it.

Data processor contracts: GDPR Article 28 requires Data Processing Agreements with every vendor processing personal data on your behalf. DPDP requires equivalent contracts with Data Processors covering processing scope, security obligations, breach notification upstream, and deletion on termination. The structure of these contracts is closely similar. GDPR DPAs in place with your vendors need review and gap-filling for DPDP-specific requirements, not wholesale replacement.

Security safeguards: Both frameworks require technical and organisational security measures proportionate to the risk of processing. The specific controls DPDP names, access controls, logging, monitoring, backups, breach detection, overlap substantially with the technical measures required under GDPR Article 32. A security programme built to GDPR standards covers most of what DPDP's security safeguards require, with the DPDP-specific addition of security controls assessed against the Indian regulatory standard rather than solely the EU one.

Individual rights fulfilment: Both frameworks give individuals the right to access their data and request correction. DPDP's rights set is narrower, it does not include portability or objection to automated processing. So the rights fulfilment infrastructure built for GDPR users already covers what DPDP requires for Indian users. The process needs to be mapped to the Data Protection Board as the relevant Indian authority and to DPDP's specific rights terminology, but the operational infrastructure does not need to be rebuilt.

Breach response: Both frameworks require notification to a regulatory authority and to affected individuals. The incident response process, forensic capability, and communication templates built for GDPR breach response are reusable for DPDP with specific modifications for the DPDP notification window and no-threshold requirement covered below.

Digisecuritas' DPDP Compliance Services begin every dual-framework engagement with a structured mapping of existing GDPR controls against DPDP requirements, identifying what carries over and what specifically needs to be built. So the programme builds on what works rather than duplicating effort.

The Gaps That Need Dedicated DPDP Treatment

The shared foundation covers a lot. These are the areas that do not carry over cleanly and need specific DPDP treatment.

Breach notification threshold

This is the most operationally significant divergence between the two frameworks, and it requires a dedicated solution rather than a policy update.

Under GDPR, your incident response process includes a harm assessment step before triggering notification. If a breach is unlikely to result in risk to individuals' rights and freedoms, it is documented internally and not reported. That filter means many low-severity incidents are managed without regulatory notification.

Under DPDP, that filter does not exist. Any personal data breach regardless of scale, sensitivity, or likely harm, triggers the obligation to notify the Data Protection Board immediately and affected Indian users within 72 hours.

Running a unified incident response process that applies the GDPR harm assessment to all incidents will result in DPDP notification failures for low-severity incidents involving Indian user data. The solution is a parallel notification track within your incident response process: when Indian user data is involved in any breach, the DPDP track activates immediately without the harm assessment gate that governs the GDPR track.

This is a process design change, not a technology change. It requires your incident response team to know which incidents involve Indian user data, and to apply the correct notification track for each affected user population. Our ransomware incident response playbook covers the underlying incident response discipline, and the DPDP notification track needs to be built as a specific branch within that process.

Lawful basis for processing Indian user data

GDPR provides six lawful bases for processing, including legitimate interests which most SaaS companies use extensively for analytics, fraud prevention, product improvement, and similar activities that are difficult to obtain explicit consent for at scale.

DPDP provides two: consent, and a narrow legitimate use category that covers government-mandated processing, employment-related processing, and specific public-interest scenarios. Commercial processing that GDPR covers under legitimate interests has no equivalent DPDP basis.

Every processing activity in your data map that relies on GDPR legitimate interests needs an individual assessment for Indian users: can it be re-based on consent, does it fall within DPDP's legitimate use category, or does it need to stop for Indian users? This audit is one of the most practically consequential steps in building a dual compliance programme, because the outcomes drive product and engineering changes, not just policy updates.

Consent notice format and language

GDPR requires clear, plain-language consent notices but does not mandate a specific format or language availability requirement.

DPDP requires a standalone consent notice, separate from terms of service and privacy policies in plain language, available in any of India's 22 scheduled languages on request. The content requirements also differ: the DPDP notice must specify the purpose of processing, the categories of data, and the mechanism to withdraw consent, in terms a user without legal or technical knowledge can understand.

For most SaaS companies, this means creating a separate consent notice infrastructure for Indian users, the same underlying data as your GDPR privacy notices, reformatted into standalone notices per processing purpose, with a language-on-request capability built into your consent management system.

Grievance Redress Officer

DPDP requires every Data Fiduciary to appoint a Grievance Redress Officer and publish their contact details so Indian users can raise complaints. GDPR has no equivalent requirement. Its complaint mechanism runs through supervisory authorities, not a designated internal officer.

For most SaaS companies, the Grievance Redress Officer function can be held by an existing senior compliance, legal, or privacy role. It does not require a dedicated hire in most cases. What it requires is a formal appointment, published contact details, and a documented process for handling complaints within the timelines the Act and Rules specify.

Data principal rights mapping

GDPR's rights framework and DPDP's rights framework overlap but are not identical. Rights fulfilment processes built for GDPR users work for DPDP users in most respects, but they need to be mapped to:

• The Data Protection Board as the relevant authority for Indian user complaints (not EU supervisory authorities)

• DPDP's specific rights terminology and the Act's rights provisions rather than GDPR Article terminology

• The right to nominate, a DPDP-specific right with no GDPR equivalent, allowing users to nominate someone to exercise their rights in the event of death or incapacity

How to Structure the Unified Programme

A unified GDPR and DPDP compliance programme has three layers.

Layer 1: Shared controls. The data map, processor contracts, security safeguards, and rights fulfilment infrastructure apply to both frameworks. Build these once, maintain them centrally, and map each control to both GDPR and DPDP requirements. Evidence collected for one framework should satisfy the other where controls overlap which reduces audit preparation time significantly.

Layer 2: Framework-specific additions. The DPDP-specific requirements, standalone consent notices, Grievance Redress Officer, no-threshold breach notification track, legitimate interests audit are additions to the shared foundation, not replacements of it. Build these as extensions of existing infrastructure rather than parallel systems.

Layer 3: User population tagging. The controls that differ between frameworks need to be applied based on which user population's data is involved. This requires your systems to tag data by user geography, EU users get GDPR-governed processing, Indian users get DPDP-governed processing, users in both get both applied. That tagging is a technical requirement that most SaaS companies underestimate when planning a dual compliance programme.

According to IAPP's analysis of India's DPDP compliance landscape, companies that approach DPDP as an extension of existing GDPR infrastructure rather than a parallel programme reduce their total compliance cost by an estimated 40 to 60 percent compared to building separate programmes, primarily because the data mapping, processor contract, and security control work does not need to be duplicated.

The same discipline applies to how security controls are managed across both frameworks. Our guide on SOC 2 vs ISO 27001 for SaaS companies covers how overlapping compliance frameworks can be mapped to shared controls, the same approach applies to GDPR and DPDP.

A Practical Gap Assessment Checklist for Dual Compliance

Use this to identify what your existing GDPR programme already covers for DPDP and what specifically needs to be built.

Shared controls, check these carry over correctly:

• Data map covers all Indian user data flows, not just EU user data

• Data Processor contracts with all vendors handling Indian user data meet DPDP contractual requirements (not just GDPR Article 28)

• Security safeguards assessed against DPDP Rules requirements, not only GDPR Article 32

• Rights fulfilment process covers DPDP rights set and maps to Data Protection Board as Indian authority

• Breach response process is tested and capable of meeting both GDPR 72-hour and DPDP immediate notification windows

DPDP-specific additions, build these:

• Parallel breach notification track for Indian user data that bypasses the GDPR harm assessment filter

• Legitimate interests audit completed for all processing activities involving Indian user data

• Standalone DPDP consent notices created per processing purpose, separate from GDPR privacy notices

• Language-on-request capability built into consent management for 22 scheduled Indian languages

• Grievance Redress Officer appointed and contact details published

• Right to nominate process designed and documented

• User geography tagging implemented to apply the correct framework to the correct data population

What Significant Data Fiduciaries Need to Add

If your SaaS is at risk of SDF designation, large volume, sensitive data categories, financial or health sector, the unified programme needs a third layer covering SDF-specific obligations: India-based DPO, annual DPIAs, independent audits, and localisation readiness. These are additions to the dual compliance foundation, not substitutes for it.

Our piece on what DPDP regulators expect from a Significant Data Fiduciary covers the SDF-specific obligations and how to assess your designation risk.

Conclusion

The SaaS companies that will find DPDP compliance most manageable by May 2027 are the ones treating it as an extension of existing GDPR work rather than a separate compliance project. The shared foundation is real and substantial. The gaps are specific, addressable, and mostly narrow enough that they do not require rebuilding what already works.

What they do require is being mapped deliberately rather than assumed away. The breach notification threshold, the legitimate interests gap, and the consent notice format are the three areas where assuming GDPR compliance equals DPDP compliance creates the most regulatory exposure and they are all buildable as additions to your existing programme rather than replacements of it.

Digisecuritas helps SaaS companies run the structured gap assessment that identifies what their GDPR programme already covers for DPDP and what specifically needs to be built, then delivers the DPDP additions as extensions of existing compliance infrastructure.
