Shashank Bajpai, CISO & CTSO at Yotta 2026 is the execution year for India’s Digital Personal Data Protection (DPDP) regime , the Rules were notified in November 2025 and the government has signalled a phased enforcement timeline. The law is consent-centric, imposes heavy penalties (up to ₹250 crore for the most serious security failures), creates a new institutional stack (Data Protection Board, Consent Managers), and elevates privacy to boardroom priority. Organizations that treat compliance as a strategic investment, not a cost centre, will gain trust, operational resilience, and competitive advantage. Key themes for 2026: consent at scale, data minimization, hardened security, vendor accountability, and new dependency risks arising from Consent Manager infrastructure.

Why 2026 Matters

The DPDP Act (2023) becomes operational through Rules notified in November 2025; the result is a staggered compliance timetable that places 2026 squarely in the execution phase. That makes 2026 the inflection year when planning becomes measurable operational work and when regulators will expect visible progress. The practical effect is immediate: companies must move from policy documents to implemented consent systems, security controls, breach workflows, and vendor governance.

The High-Impact Obligations

• Explicit consent architecture: Consent must be free, specific, informed and obtained by clear affirmative action. Systems must record, revoke and propagate consent signals reliably.
• Data minimization & purpose limitation: Collect only what’s necessary and purge data when the purpose is fulfilled.
• Reasonable security safeguards: Highest penalty bracket (up to ₹250 crore) for failures to implement required security measures. Encryption, tokenization, RBAC, monitoring and secure third-party contracts are expected.
• Breach notification: Obligatory notification to the Data Protection Board and affected principals, with tight timelines (public guidance references 72-hour reporting windows for board notification).
• Data subject rights: Access, correction, erasure, withdrawal of consent and grievance mechanisms must be operational and auditable.
• Children’s data: Verifiable parental consent and prohibitions on behavioural profiling/targeted advertising toward minors; failures risk very high penalties.
• Consent Managers: New regulated intermediaries where individuals may centrally manage consent; only India-incorporated entities meeting financial/operational thresholds (minimum net worth indicated in Rules) can register. This constructs a new privacy infrastructure and a new dependency vector for data fiduciaries.

Implementation Challenges & Strategic Opportunities

1. Key Implementation Challenges

Challenge Area	What Will Break / Strain in 2026	Why It Matters to Leadership	Strategic Imperative
Regulatory Ambiguity & Evolving Interpretation	Unclear operational expectations around “informed consent,” Significant Data Fiduciary designation, and cross-border data transfers	Risk of over-engineering or non-compliance as regulatory guidance evolves	Build modular, configurable privacy architectures that can adapt without re-platforming
Legacy Systems & Distributed Data	Difficulty retrofitting consent enforcement, encryption, audit trails, and real-time controls into legacy and batch-oriented systems	High cost, operational disruption, and extended timelines for compliance	Prioritize modernization of high-risk systems and align vendor roadmaps with DPDP requirements
Organizational Governance & Talent Gaps	Privacy cuts across legal, product, engineering, HR, procurement—often without clear ownership; shortage of experienced DPOs	Fragmented accountability increases regulatory and breach risk	Establish cross-functional privacy governance; leverage fractional DPOs and external advisors while building internal capability
Children’s Data & Onboarding Friction	Age verification and parental consent slow user onboarding and impact conversion metrics	Direct revenue and growth impact if UX is not carefully redesigned	Re-engineer onboarding flows to balance compliance with user experience, especially in consumer platforms
Consent Manager Dependency & Systemic Risk	Outages or breaches at registered Consent Managers can affect multiple data fiduciaries simultaneously	Creates concentration and third-party systemic risk	Design fallback mechanisms, redundancy plans, and enforce strong SLAs and audit rights

Board-Level Takeaway

DPDP compliance in 2026 is not a one-time legal exercise, it is an operating model change. Organizations that treat privacy as a board-governed, product-integrated, and metrics-driven discipline will outperform peers on regulatory trust, customer confidence, and incident resilience.

The Macro View: Data Sovereignty & Trust Infrastructure

The Rules reinforce India’s intention to control flows of citizen data while creating domestic privacy infrastructure (DPB + Consent Managers + data auditors). This is not just regulation; it is an economic strategy to build domestic capability in cloud, identity, security and RegTech, and to position India as a credible participant in global data governance conversations.

Act Strategically, Not Reactively

DPDP is a structural shift: it will change products, engineering practices, contracts, and customer expectations. 2026 will reveal winners and laggards. Those that embrace privacy as a governance discipline and a product differentiator will realize measurable advantages in trust, operational resilience, and market value. The alternative, waiting until enforcement escalates, risks fines, reputational harm and erosion of customer trust.

India’s Department of Telecommunications (DoT) has introduced a shift in the way messaging platforms operate in the country, mandating the adoption of SIM-binding as a core security requirement. Under the Telecommunication Cybersecurity Amendment Rules, 2025, all major messaging services, including Telegram, and regional platforms such as Arattai, must ensure that their applications remain continuously linked to an active SIM card on the user’s device.   The mandate is part of the government’s intensified efforts to combat cyber fraud and strengthen nationwide cybersecurity compliance. The directive requires App-Based Communication Service providers to implement persistent SIM-linking within 90 days and submit detailed cybersecurity compliance reports within 120 days. The move seeks to eliminate longstanding gaps in identity verification systems that have enabled malicious actors to misuse Indian mobile numbers from outside the country. 

New Rules for SIM-Binding Communication 

According to the new requirements, messaging services must operate only when the user’s active SIM card matches the credentials stored by the app. If a SIM card is removed, replaced, or deactivated, the corresponding app session must immediately cease to function. The rules also extend to web-based interfaces: platforms must automatically log users out at least every six hours, requiring a QR-based reauthentication that is tied to the same active SIM.  These changes aim to reduce the misuse of Indian telecom identifiers, which authorities say have been exploited for spoofing, impersonation, and other forms of cyber fraud. By enforcing strict SIM-binding, the DoT intends to establish a clearer traceability chain between the user, their device, and their telecom credentials. 

Why Stricter Controls Were Needed 

Government observations revealed that many communication apps continued functioning even after the linked SIM card was removed. This allowed foreign-based actors to operate accounts associated with Indian mobile numbers without proper authentication. The ability to hijack accounts or mask locations contributed directly to an uptick in cybercrimes, often involving financial scams or identity theft.  Industry groups had previously flagged this vulnerability as well. The Cellular Operators Association of India (COAI), for instance, noted that authentication typically occurs only once, during initial setup, which leaves apps operational even if the SIM is no longer present. By requiring ongoing SIM-binding, authorities aim to close this loophole and establish reliable verification pathways essential for cybersecurity compliance.  The new mandate draws support from multiple regulatory frameworks, including the Telecommunications Act, 2023, and subsequent cybersecurity rules issued in 2024 and 2025. Platforms that fail to comply could face penalties, service restrictions, or other legal consequences under India’s telecom and cybersecurity laws. 

Impact on Platforms and Users 

Messaging platforms must redesign parts of their infrastructure to support real-time SIM authentication and implement secure logout mechanisms for multi-device access. They are also expected to maintain detailed logs and participate in audits to demonstrate cybersecurity compliance.  For users, the changes may introduce constraints. Accessing a messaging app without the original active SIM will no longer be possible. Cross-device flexibility, particularly through desktop or browser-based interfaces, may also be reduced due to the six-hour logout requirement. However, policymakers argue that these inconveniences are offset by a reduced risk of cyber fraud.  India’s focus on SIM-binding aligns with practices already common in financial services. Banking and UPI applications, for example, require an active SIM for verification to minimize fraud. Other regulators have taken similar steps: earlier in 2025, the Securities and Exchange Board of India (SEBI) proposed linking trading accounts to specific SIM cards and incorporating biometric checks to prevent unauthorized transactions. 

India Mandates Pre-Installed Cybersecurity App on Smartphones

In a parallel move to strengthen digital security, India’s telecom ministry has ordered all major smartphone manufacturers, including Apple, Samsung, Vivo, Oppo, and Xiaomi, to pre-install its cybersecurity app Sanchar Saathi on all new devices within 90 days, and push it via updates to existing devices. The app must be installed in a way that users cannot disable or delete it. Launched in January, Sanchar Saathi has already helped recover over 700,000 lost phones, blocked 3.7 million stolen devices, terminated 30 million fraudulent connections, and assists in tracking devices and preventing counterfeit phones. The app verifies IMEI numbers, blocks stolen devices, and combats scams involving duplicate or spoofed IMEIs. The move is aimed at strengthening India’s telecom cybersecurity but may face resistance from Apple and privacy advocates, as Apple traditionally opposes pre-installation of government or third-party apps. Industry officials have expressed concerns over privacy, user choice, and operational feasibility, while the government emphasizes the app’s role in digital safety and fraud prevention.
