If I had a rupee for every time a client told me "we are already GDPR compliant, so we should be fine with DPDP" — I could retire.
Here is the reality: GDPR compliance gives you a head start, but it does not make you DPDP compliant. The two laws share the same DNA (both are consent-based, rights-driven data protection frameworks), but they differ in ways that matter operationally.
I have implemented both frameworks at multiple companies. Here are the nine differences that actually affect how you run your business.
1. Scope of Personal Data
GDPR: Covers all personal data — digital and physical (paper files, verbal information, CCTV footage).
DPDP: Covers only digital personal data, plus offline data that gets digitised. Your paper HR files are out of scope unless you scan them into a system.
Practical impact: If you have extensive paper-based processes, DPDP has a narrower scope. But let us be honest — in 2026, almost everything is digital anyway.
2. Lawful Bases for Processing
GDPR: Six lawful bases — consent, contract, legal obligation, vital interests, public task, and legitimate interests.
DPDP: Primarily two — consent and "certain legitimate uses" (a narrower concept than GDPR's legitimate interests). The legitimate uses are defined in the Act and include things like employment purposes, medical emergencies, and compliance with court orders.
Practical impact: If you rely on "legitimate interests" under GDPR for marketing or analytics, that justification may not hold under DPDP. You might need explicit consent instead.
3. Data Protection Officer
GDPR: Required for public bodies and organisations that do large-scale monitoring or process sensitive data.
DPDP: Required only for "Significant Data Fiduciaries" — a category determined by the government based on volume and sensitivity of data processed. Most SMBs will likely not fall in this category.
Practical impact: If you had to appoint a DPO under GDPR, you might not need one under DPDP. But I still recommend designating someone internally as your privacy lead.
4. Children's Age Threshold
GDPR: Varies by EU member state, ranging from 13 to 16 years.
DPDP: Fixed at 18 years across the board. No exceptions, no state-level variation.
Practical impact: If your platform serves users between 13-17, you were fine under GDPR (in some countries) but need verifiable parental consent under DPDP. This is a significant operational change for gaming, social media, and ed-tech companies.
5. Data Protection Impact Assessment
GDPR: Required for high-risk processing. Detailed guidance from supervisory authorities on when and how.
DPDP: Required only for Significant Data Fiduciaries. The format and triggers are yet to be fully specified in the rules.
Practical impact: For most Indian companies, DPIA is not a DPDP requirement. But it remains a best practice, especially if you are processing sensitive data at scale.
6. Right to Data Portability
GDPR: Data principals can request their data in a machine-readable format and have it transferred to another controller.
DPDP: No explicit right to data portability. Data principals can access a summary of their data, but there is no obligation to provide it in a portable format.
Practical impact: If you built data export features for GDPR, they are nice to have but not a DPDP obligation.
7. Penalty Structure
GDPR: Up to 20 million euros or 4% of global annual turnover, whichever is higher.
DPDP: Fixed monetary caps per violation type — up to ₹250 crore (approximately 27 million euros). No turnover-based calculation.
Practical impact: For large multinationals, GDPR penalties can be higher (4% of global turnover can be billions). For smaller companies, DPDP penalties are actually steeper in absolute terms.
8. Cross-Border Transfers
GDPR: Complex mechanism with adequacy decisions, Standard Contractual Clauses, Binding Corporate Rules, etc.
DPDP: Simple blocklist approach — transfer anywhere except to countries the government explicitly restricts. No adequacy decisions, no SCCs required.
Practical impact: Cross-border transfers are actually easier under DPDP than GDPR. Until the restricted list is published, transfers to all countries are permitted.
9. Regulatory Body
GDPR: Established supervisory authorities in each EU country with years of enforcement history, guidelines, and precedent.
DPDP: The Data Protection Board of India is new. No enforcement history yet. No published guidelines on interpretation.
Practical impact: There is uncertainty about how strictly the Board will enforce and how they will interpret ambiguous provisions. This is both a risk (you cannot predict outcomes) and an opportunity (proactive compliance will be viewed favourably by a new regulator).
What This Means for Your GDPR-Compliant Organisation
If you are already GDPR compliant, you are probably 60-70% of the way there with DPDP. The gaps are typically:
- Consent mechanisms that rely on legitimate interests (need to switch to explicit consent under DPDP)
- Children's data processing (age threshold difference)
- Indian-specific breach notification requirements
- Updated privacy notice that references DPDP-specific rights and obligations
Do not assume compliance with one means compliance with both. Run a separate DPDP gap assessment against the specific requirements of the Indian Act.
