Consent Manager Requirements Under DPDP: Cost and Build vs Buy
DPDP's consent manager framework is still being operationalized, most companies are better served buying a compliant consent management platform than building one in-house.
DPDP requires valid, informed, specific consent before processing personal data for most purposes, and introduces the concept of registered "Consent Managers" as intermediaries individuals can use to manage consent across services. For an individual company's own compliance (as opposed to operating as a registered Consent Manager itself, a distinct, more heavily regulated role), the practical requirement is a consent capture and management system that can record what was consented to, when, and allow easy withdrawal.
Building this in-house is possible but rarely the efficient choice, several consent management platforms already support DPDP-specific requirements (granular consent categories, withdrawal mechanisms, audit trails) at a subscription cost that's typically far lower than the engineering time to build and maintain an equivalent system internally.
The decision point is less "build vs buy" and more "which existing platform's DPDP feature set actually matches our data flows", evaluating 2 to 3 vendors against the company's specific consent scenarios is usually a faster path to compliance than a custom build.
