DPDP and Cybersecurity: Why the Safest Data May Be the Data You Delete

Why It Matters

By trimming unused data, companies lower breach risk, avoid hefty fines, and build trust that can become a market advantage.

Key Takeaways

• 70% of enterprise sensitive data remains untouched, increasing breach surface.
• Indian breach cost averages $2.6 M, versus $4.44 M global average.
• DPDP penalties can reach $30 M for security failures.
• Data minimization cuts breach risk, improves visibility, and boosts accountability.
• Demonstrating purposeful data handling turns trust into a market advantage.

Pulse Analysis

The surge in unused personal data is reshaping India’s cyber risk landscape. A 2021 report shows that 70 % of sensitive records have not been accessed for years, yet they remain exposed in breach scenarios. IBM’s 2025 research puts the average Indian data‑breach cost at roughly $2.6 million, compared with a $4.44 million global average, while CERT‑In logged more than 2.9 million incidents in 2025. These figures prompted the government to enact the Digital Personal Data Protection (DPDP) framework, which treats data hoarding as a security liability rather than an asset.

DPDP’s core tenet—data minimization—acts as a practical cyber‑defense layer. By deleting records that have outlived their business purpose, firms shrink the attack surface, lower the potential impact of a breach, and gain clearer visibility into where personal data resides. The law also imposes steep penalties, up to $30 million for inadequate safeguards and $24 million for delayed breach notification, forcing security, privacy, and operations teams to collaborate on a unified data‑governance map. In practice, this means tighter access controls, automated retention policies, and continuous audit of shadow databases and third‑party copies.

Beyond compliance, disciplined data handling is emerging as a competitive differentiator. Enterprises that can prove they collect only what is needed, protect it rigorously, and delete it promptly earn stronger customer trust and smoother partner relationships. Boards are shifting their KPI from “DPDP compliant” to “risk‑reduced through data hygiene.” As synthetic‑identity fraud and AI‑driven attacks grow, purpose‑bound data collection will enable more precise fraud models without the baggage of unnecessary information. In the DPDP era, the safest data is the data never gathered—or promptly erased—making data minimization one of the most effective security controls available.
