ISO 27001:2022 Post-Transition: What Happens to Your ISMS Now
FAQ: Data Privacy Questions From Data Protection Officers
Role and Responsibilities Questions
Q1: What exactly is a Data Protection Officer supposed to do under DPDP?
The DPO serves as the point of contact between the organization and the Data Protection Board of India. Your responsibilities include overseeing the organization’s data protection strategy, ensuring compliance with the DPDP Act and Rules, serving as the contact point for data principals exercising their rights, liaising with the Data Protection Board, and conducting or overseeing data protection impact assessments. The role requires both legal understanding and operational capability – you need to understand the law and translate it into processes your organization can execute.
Q2: Do I need to be based in India to serve as DPO?
For Significant Data Fiduciaries, the DPO must be based in India. This is an explicit requirement under the DPDP Act. For other data fiduciaries, while there is no strict residency requirement for the privacy lead, having someone in India who understands the local regulatory landscape and can engage with the Data Protection Board is practically essential.
Q3: Can the DPO role be combined with other positions?
The DPDP Act does not explicitly prohibit dual roles, but the DPO must have sufficient authority and independence to fulfill the role effectively. Avoid combining the DPO role with positions that create conflicts of interest – for example, the DPO should not also head the marketing function that relies heavily on personal data processing.
Consent and Legal Basis Questions
Q4: What makes consent valid under DPDP?
Consent must be free, specific, informed, unconditional, and unambiguous. It must be given through a clear affirmative action. Pre-ticked checkboxes, consent bundled with terms of service, or consent conditional on receiving a service are not valid. Each purpose of processing requires separate consent, and data principals must be able to withdraw consent as easily as they gave it.
Q5: Can we process personal data without consent?
Yes, in specific circumstances called legitimate uses. These include processing necessary for the performance of a function under law, compliance with court orders or judgments, responding to medical emergencies, processing for employment purposes, and processing in the public interest. Each legitimate use has specific conditions that must be met – it is not a blanket exception.
Q6: How should we handle consent for data we collected before DPDP came into force?
You need to provide a notice to data principals about the personal data you already hold and the purposes for which it was collected. If the original collection was based on consent, that consent remains valid provided the purpose has not changed. If you want to use previously collected data for new purposes, you need fresh consent. The DPDP Compliance Rules specify the timeline for sending these retrospective notices.
Q7: Do we need consent for every cookie on our website?
DPDP focuses on personal data processing, not specifically on cookies. However, cookies that collect or process personal data – such as those used for behavioral tracking, personalization, or analytics that identify individuals – require consent. Strictly necessary cookies that are essential for website functionality may not require consent, but this should be assessed case by case.
Data Rights and Breach Questions
Q8: What is the timeline for responding to data principal rights requests?
The DPDP Rules specify response timelines for rights requests. You should aim to acknowledge receipt within 48 hours and complete the request within the prescribed period. Having a documented workflow with assigned responsibilities and tracking mechanisms is essential for meeting these timelines consistently.
Q9: What counts as a personal data breach under DPDP?
A personal data breach is any unauthorized processing, accidental or unlawful destruction, loss, alteration, disclosure, or access to personal data. This is broader than just external hacking – it includes accidental data exposure, misdirected emails containing personal data, lost devices with unencrypted personal data, and insider access violations.
Q10: How quickly must we report a breach?
The DPDP Act requires notification to the Data Protection Board and affected data principals without unreasonable delay. The DPDP Rules provide more specific timelines. Your incident response plan should include clear criteria for when a security incident becomes a reportable personal data breach, and the notification process should be pre-documented so it can be executed quickly during a real incident.
Q11: Do we need to notify every data principal affected by a breach?
Yes, when the breach is likely to cause harm to the data principal. The notification must describe the nature of the breach and the measures the data principal can take to protect themselves. The Data Protection Board may also direct specific remedial actions.
Cross-Border and Vendor Questions
Q12: Can we transfer personal data outside India?
The DPDP Act permits cross-border transfer of personal data to countries that are not on the restricted list published by the central government. If your data processing involves transfers to countries on the restricted list, those transfers are prohibited unless specifically exempted. For countries not on the restricted list, transfers are permitted, but you must ensure that the processing by the overseas entity complies with the Act’s requirements through appropriate contractual arrangements.
Q13: What data processing agreements do we need with our vendors?
Every data processor that processes personal data on your behalf must be governed by a valid contract or data processing agreement. This agreement should specify the nature and purpose of processing, the types of personal data involved, the duration of processing, the obligations of the processor regarding security measures, the requirement to delete or return data upon termination, and the audit rights of the data fiduciary.
Q14: Are cloud service providers considered data processors under DPDP?
Yes. If your organization uses cloud services to store or process personal data, the cloud provider is acting as a data processor. Your agreement with the provider must address DPDP requirements, including data localization if applicable, security measures, breach notification, and the provider’s obligations regarding data principal rights requests.
Q15: How do we manage compliance when we use multiple sub-processors?
Maintain a register of all sub-processors in your data processing chain. Ensure that each sub-processor is bound by contractual obligations that are at least as protective as your agreement with the primary processor. Implement regular assessments of sub-processor compliance and maintain visibility into where your data is being processed across the chain.
Q: Is DPO certification required under DPDP?
A: The DPDP Act does not mandate a specific certification for DPOs. However, having relevant privacy certifications demonstrates competence and is increasingly expected by organizations and regulators.
Q: Can we outsource the DPO function?
A: For non-SDF organizations, engaging an external DPO or privacy consultant is permissible. Significant Data Fiduciaries may need to evaluate whether the role can be effectively fulfilled externally given the in-India residency requirement.

Zero Trust Architecture for Banks and Financial Services
The security model that most Indian banks and financial institutions still rely on – a hardened perimeter with trusted internal networks – was designed for an era when applications ran on-premises, employees worked from office desks, and third-party integrations were limited to a few managed connections. That era is over. Today, banking applications run across cloud environments, employees access core systems from personal devices and home networks, third-party fintech integrations number in the dozens, and API-driven architectures expose services that were never designed to be internet-facing. The result is a perimeter that is more porous than most security teams acknowledge. Every VPN connection, every API endpoint, every cloud-based service creates a pathway that the traditional perimeter model assumes does not exist. Regulatory bodies have recognized this shift. RBI’s cybersecurity guidelines emphasize defense-in-depth, microsegmentation, and continuous monitoring – concepts that align directly with zero trust principles. SEBI’s CSCRF requires network segmentation and access controls that go beyond perimeter-based thinking. PCI DSS 4.0.1’s requirement for internal network segmentation and multi-factor authentication for all CDE access moves in the same direction. The question is no longer whether financial institutions should adopt zero trust, but how to implement it pragmatically within existing regulatory and operational constraints.
What Zero Trust Actually Means for a Bank
Zero trust is not a product you purchase. It is an architectural approach built on a simple principle – never trust, always verify. Every access request is evaluated based on the identity of the requester, the security posture of their device, their location and behavior patterns, and the sensitivity of the resource they are requesting. There is no implicit trust granted by virtue of being on the corporate network. For a bank, this translates to concrete operational changes. Network access moves from flat internal networks to microsegmented zones where each application, database, and service sits in its own security boundary. Authentication shifts from single-factor VPN access to continuous, risk-based authentication that evaluates multiple signals before granting access. Authorization becomes granular – a user’s access to the core banking system does not automatically grant access to the card management system, even if both sit on the same network. Data protection moves from perimeter-based controls to data-centric controls where encryption, classification, and access policies follow the data regardless of where it resides. This does not mean ripping out your existing infrastructure. Zero trust is a journey implemented incrementally. Start with identity, expand to device trust, then move to network microsegmentation and data-centric security.
Mapping Zero Trust to Indian Regulatory Requirements
RBI’s cybersecurity framework for banks and non-bank PSOs emphasizes several principles that align directly with zero trust. The requirement for network segmentation maps to microsegmentation. The requirement for strong access controls maps to identity-based access with continuous verification. The requirement for continuous monitoring maps to zero trust’s emphasis on real-time security analytics. For PCI DSS 4.0.1, zero trust supports multiple requirements simultaneously. Requirement 1 on network security controls benefits from microsegmentation. Requirement 7 on access restriction by business need-to-know aligns with least-privilege access policies. Requirement 8 on authentication maps to zero trust’s identity verification approach. Requirement 10 on logging and monitoring aligns with zero trust’s continuous monitoring. SEBI’s CSCRF requires regulated entities to implement defense-in-depth strategies with multiple layers of security controls. Zero trust is fundamentally a defense-in-depth architecture – it layers identity verification, device assessment, network controls, and data protection into a comprehensive security model. By implementing zero trust, you address multiple regulatory requirements simultaneously rather than implementing point solutions for each. This creates both a stronger security posture and a more efficient compliance program.
A Phased Implementation Roadmap
Phase one focuses on identity and access management – 3-6 months. Implement a centralized identity provider with multi-factor authentication for all critical systems. Deploy conditional access policies that evaluate user identity, device health, and location before granting access. This phase has the highest return on investment because identity compromise is the most common attack vector in financial services. Phase two addresses device trust – 2-4 months. Implement endpoint detection and response across all devices that access your environment. Deploy device health checks that evaluate patch status, security software presence, and configuration compliance before allowing connections. Devices that do not meet your security baseline are either remediated or quarantined. Phase three tackles network microsegmentation – 6-12 months. This is the most operationally complex phase. Begin by identifying your most critical applications and data stores – core banking, card management, treasury systems – and creating microsegments around them. Use software-defined networking or next-generation firewalls to enforce segment boundaries. Monitor east-west traffic within segments to detect lateral movement. Phase four implements data-centric security – ongoing. Classify your data based on sensitivity, apply encryption and access controls based on classification, and implement data loss prevention controls. This phase ensures that even if perimeter and network controls fail, data itself is protected.
Common Mistakes When Implementing Zero Trust in Banking
The first mistake is treating zero trust as a technology purchase. Vendors will sell you zero trust products, but zero trust is an architecture and a philosophy. The technology enables the architecture, but without proper design and process changes, the technology alone delivers limited value. The second mistake is attempting to implement zero trust across the entire organization simultaneously. This creates operational disruption, user resistance, and project fatigue. Start with a specific use case – remote access to the core banking system, third-party vendor access, or cloud application access – and expand from there. The third mistake is neglecting the user experience. If zero trust controls make legitimate work harder, users will find workarounds that undermine the security model. Design authentication flows that are seamless for low-risk activities and step up only when the risk warrants it. Risk-based authentication – evaluating context signals to determine authentication strength – is essential for user acceptance. The fourth mistake is insufficient monitoring. Zero trust generates substantially more data than traditional perimeter security – every access decision, device posture assessment, and policy evaluation creates a log entry. Without proper SIEM capacity and alert tuning, security teams get overwhelmed by noise and miss the signals that matter. Invest in detection engineering alongside your zero trust deployment.
Q: Is zero trust mandated by RBI?
A: RBI does not use the term ‘zero trust’ in its guidelines, but the principles it mandates – network segmentation, strong access controls, continuous monitoring, and defense-in-depth – align directly with zero trust architecture.
Q: How long does it take to implement zero trust in a bank?
A: A phased implementation typically spans 12-24 months. Identity and access management improvements can be implemented in 3-6 months, with network microsegmentation taking 6-12 months.
Q: Does zero trust replace our firewall and VPN?
A: Zero trust does not eliminate firewalls – it changes how they are used. Firewalls shift from perimeter gatekeepers to microsegmentation enforcers. VPN may be replaced by zero trust network access solutions that provide more granular, identity-based access.

DPDP Act Enforcement Begins: Your 90-Day Compliance Playbook
FAQ: Compliance Questions Every Fintech Founder Should Ask
Regulatory and Licensing Questions
Q1: Which compliance frameworks apply to my fintech?
It depends on what your company does. If you process, store, or transmit payment card data – PCI DSS. If you operate as a payment aggregator or payment gateway – RBI PA/PG guidelines. If you handle personal data of Indian citizens – DPDP Act. If your clients are SEBI-regulated entities – their CSCRF requirements flow down to you as a vendor. If you serve US or EU enterprise clients – they will likely require SOC 2. Start by mapping your data flows and identifying which regulatory bodies have jurisdiction over your operations.
Q2: Do I need RBI approval to operate as a payment aggregator?
Yes. Following the RBI’s guidelines on PA/PG regulation, payment aggregators must obtain authorization from RBI. This involves meeting net worth requirements, implementing security controls, establishing a grievance redressal mechanism, and maintaining a designated nodal officer. The application process can take 12-18 months, and operating without authorization exposes your company to regulatory action.
Q3: At what stage should I start thinking about compliance?
From day one of handling sensitive data. The common mistake is treating compliance as a later-stage activity. Building compliance into your architecture and processes from the start is significantly cheaper than retrofitting later. At minimum, implement encryption, access controls, and logging from your first production deployment.
Security and Data Protection Questions
Q4: We are a small team. Do we really need a formal security program?
Yes. The size of your team does not change the regulatory requirements or the risk. What changes is the scale of implementation. A 10-person fintech does not need a 50-page security policy manual. But it does need documented access controls, encryption for sensitive data, regular vulnerability scans, incident response procedures, and security awareness training for every team member. Regulators and enterprise clients will ask for evidence of these controls regardless of your company size.
Q5: How do we handle data localization requirements in India?
RBI mandates that payment data related to Indian transactions must be stored in India. This includes the full end-to-end transaction data, not just a copy. If you use cloud infrastructure, ensure your data residency settings restrict payment data to Indian regions. For DPDP compliance, the rules specify conditions for cross-border transfer of personal data, with certain countries approved and others requiring additional safeguards.
Q6: What is the minimum security testing we should be doing?
At minimum – quarterly vulnerability scans of your external-facing systems and an annual penetration test. If you handle payment card data, PCI DSS mandates both. Beyond the minimum, implement SAST and DAST in your development pipeline, conduct security code reviews for critical components, and perform a penetration test before every major release. For early-stage companies, a focused penetration test of your core product is more valuable than a broad but shallow scan.
Certification and Audit Questions
Q7: What is the difference between PCI DSS SAQ and ROC?
A Self-Assessment Questionnaire is a self-validation tool for merchants and service providers with lower transaction volumes or simpler environments. A Report on Compliance is a detailed assessment conducted by a Qualified Security Assessor. Which one you need depends on your transaction volume, processing model, and what your acquiring bank requires. Service providers processing over 300,000 transactions annually typically need an ROC.
Q8: How long does it take to get PCI DSS certified?
For a first-time certification with no existing controls, expect 6-12 months including gap assessment, remediation, and the formal assessment. If your organization already has mature security controls, the timeline can be shorter. The assessment itself typically takes 4-8 weeks of active engagement, but the preparation is where most of the time is spent.
Q9: Can we pursue multiple certifications simultaneously?
Yes, and it is often more efficient. PCI DSS, ISO 27001, and SOC 2 share approximately 60% of their control requirements. An integrated compliance approach lets you implement controls once and map them across multiple frameworks, reducing the total effort. Plan your certification roadmap based on which framework your most important client or regulatory body requires first.
Q10: How much should we budget for compliance in our first year?
A useful benchmark is 5-10% of your IT budget for compliance activities in the first year, decreasing as controls mature. This includes assessment fees, tooling, any external consulting, and internal staff time. For a seed-stage fintech, this might be 10-15 lakhs for an initial PCI DSS SAQ and basic security testing. For a Series A company pursuing PCI DSS ROC and SOC 2, budget 30-50 lakhs including both assessments.
Operational and Growth Questions
Q11: How do we handle compliance when we are iterating quickly?
Build compliance checkpoints into your development process rather than treating it as a separate activity. Include security requirements in your user stories. Implement automated security testing in your CI/CD pipeline. Require security review for changes that affect the cardholder data environment or personal data processing. The goal is compliance as code, not compliance as a project.
Q12: Our client is asking for a compliance certificate we have never heard of. What do we do?
First, understand what the certificate actually assesses. Search for the standard name plus the issuing body. Then determine whether the requirement is coming from a regulatory mandate, an industry standard, or the client’s internal policy. If it is the client’s internal policy, you may be able to satisfy their requirement with an existing certification plus supplementary evidence. If it is a regulatory mandate, engage a qualified assessor who specializes in that framework.
Q13: Should we hire a CISO or outsource security leadership?
For companies under 100 employees, a virtual CISO or fractional CISO arrangement is typically more cost-effective and provides access to more experienced professionals than you could afford full-time. As your company grows and your compliance obligations expand, transition to a full-time CISO. The inflection point is usually when you are managing three or more compliance frameworks simultaneously.
Q14: How do I explain compliance costs to my investors?
Frame compliance as a market access enabler, not a cost center. Every enterprise client you win requires compliance certifications. Quantify the revenue attached to deals that require PCI DSS or SOC 2. Show the timeline – investing in compliance now accelerates your sales cycle for the next 12-24 months of enterprise deals.
Q: What is the first compliance certification a fintech should pursue?
A: Start with the certification your most important client or regulator requires. For payment companies, this is typically PCI DSS. For SaaS companies selling to US enterprise clients, SOC 2.
Q: Can a startup pass a PCI DSS audit?
A: Yes. PCI DSS does not have a minimum company size. Many startups achieve compliance through SAQ validation. The key is implementing the required controls, not having a large compliance team.

SEBI CSCRF 2026: Building Your SOC From Compliance Mandate
What’s New in PCI Secure Software Standard v2.0
The PCI Security Standards Council (PCI SSC) released version 2.0 of the PCI Secure Software Standard in January 2026, marking a major revision from the previous v1.2.1. If your organization develops, assesses, or relies on payment software, this update carries significant implications. Here’s a breakdown of what’s changed and what you need to know.
A Major Revision – Not A Minor Update
First and foremost, the PCI SSC has emphasized that this is a major revision. Unlike incremental updates, there is no definitive one-to-one mapping between v1.2.1 and v2.0. Organizations should approach this as a significant rethink of the standard’s structure, language, and scope – not simply an updated checklist.
Key Terminology Changes
One of the most immediately noticeable shifts is the language used throughout the standard. The term “Payment Software” has been removed entirely. In its place, the standard now revolves around the concept of “Sensitive Assets.” This broader framing better captures the range of data, resources, and functionality that software must protect. Several related glossary terms have also been updated:
- “Critical Asset” is now “Sensitive Asset” (and has been rewritten)
- “Sensitive Function” is now “Sensitive Functionality” (and has been rewritten)
- “Sensitive Data” and “Sensitive Resource” definitions have both been revised
- A new term, “Strong Authentication,” has been introduced
The glossary itself has been moved in-house: v2.0 includes a new Appendix A that supersedes the previously external SSF Glossary document, making all defined terms available within the standard itself. Additionally, “Control Objectives” have been renamed “Security Objectives” throughout the document.
New Companion Document: Sensitive Asset Identification
A brand-new external companion document has been introduced alongside v2.0 – the Sensitive Asset Identification document. This is not optional reading: it is a mandatory companion to the standard and forms part of its program.
The document provides additional context and examples for understanding Sensitive Assets, Sensitive Data, Sensitive Functionality, and Sensitive Resources. For vendors working with EMVCo 3DS-related data, the standard also relies on the PCI 3DS Data Matrix document.
Restructured Test Requirements And Methodology
All test requirements have been essentially rewritten in v2.0. The new approach is structured around three core methods:
- Documentation Review
- Static Analysis
- Dynamic Analysis
Additional new sections include Software Testing, Provision of Source Code, Technical Constraints, and Technical FAQs – the last of which mirrors language from existing PCI Technical FAQ documents.
Overhauled Core Requirements
The core section has been retitled “Core – All Software” to emphasize that these requirements apply universally to all software assessed under the standard. The eleven Security Objectives now cover:
- Security Objective 1: Software Architecture, Composition, and Versioning – including requirements for Bill of Materials (BOM), versioning practices, and the use of wildcards.
- Security Objective 2: Sensitive Asset Identification – relies on the new companion document covers identifying Sensitive Data, Sensitive Resources, Sensitive Functionality, and Sensitive Modes of Operation.
- Security Objective 3: Sensitive Asset Storage and Retention
- Security Objective 4: Sensitive Modes of Operation – applies only when a Sensitive Mode of Operation is present introduces “Strong Authentication.”
- Security Objective 5: Sensitive Asset Protection – including the software design itself as a sensitive asset, and formalizing the concept of “anomalous behavior.”
- Security Objective 6: Sensitive Asset Output – formalizes secure channel requirements.
- Security Objective 7: Random Numbers – covers both leveraging an external RNG and implementing one within the software.
- Security Objective 8: Key Management
- Security Objective 9: Cryptography (a single encompassing requirement for cases not covered elsewhere)
- Security Objective 10: Threats and Vulnerabilities
- Security Objective 11: Secure Deployment and Management – includes implementation guidance and software versioning.
Changes To Modules : Modules are additional requirements that apply on top of the Core – All Software section, based on defined criteria.
- Module A (Account Data Protection): Requirements have been revised to focus specifically on PAN and SAD in relation to PCI DSS.
- Module B (formerly Terminal Software Requirements, now POI Device Software): The module has been retitled and its requirements refined and reduced. Several requirements previously in Module B have been absorbed into the Core – All Software section. SRED requirements have also been revised.
- Module C (formerly Web Software Requirements, now Publicly-accessible Software): The module has been retitled to better reflect its intent. Several requirements from the old C.1 section have been moved to the Core section. Requirements C.1.5 and C.1.6 have been removed, as they are now covered by the PCI Secure SLC Standard.
- Module D (NEW – Software Development Kits): This is an entirely new module. v2.0 is now better suited to accommodate the assessment of SDKs, including EMVCo 3DS SDKs. Module D introduces a new set of objectives and requirements specifically for this category.
Structural And Administrative Changes
Several structural changes have been made to align v2.0 more closely with the broader PCI Standards framework:
- A new “Sensitive Assets” section has been added to the introduction.
- The “Stakeholder Roles and Responsibilities” section has been removed from the standard and relocated to the PCI Secure Software Program Guide.
- The “Scope of Security Requirements” section has been removed entirely.
- Related Publications have been moved to a new Appendix B.
- A new Appendix C covers Technical References.
- SLC-related requirements have been removed from this standard, as they are now covered under the PCI Secure SLC Standard.
- The standard now relies on “Strong Cryptography” as the baseline for cryptographic requirements, replacing the previous “Effective Key Strength” framework.
What This Means For Your Organization
Whether you are a software vendor seeking or maintaining certification, an assessor reviewing compliance, or a payment brand evaluating software, v2.0 represents a meaningful shift. The expanded focus on Sensitive Assets (rather than Payment Software alone) broadens the standard’s applicability. The introduction of Module D makes it relevant to SDK developers for the first time. And the comprehensive rewrite of test requirements means existing assessment processes will need to be revisited.
Organizations currently certified or in the process of certification under v1.2.1 should review the full v2.0 standard and the new Sensitive Asset Identification companion document to understand how requirements map (or don’t map) to their current implementations.
The PCI SSC has made clear that this version is designed to be more structured, more broadly applicable, and better aligned with the evolving software security landscape – including the growing role of SDKs, third-party components, and complex software supply chains.

SOC 2 for Indian Fintech: Why Global Clients Are Asking
FAQ: 15 PCI DSS Questions Every CISO Is Asking Right Now
The customized approach is new in PCI DSS 4.0 and allows organizations to meet a requirement’s security objective through an alternative control that differs from the defined approach. It is not a shortcut — it requires a more rigorous validation process, including documented evidence that the alternative control meets the stated objective. Consider it when the defined approach does not fit your technology architecture, but be prepared for additional assessment effort.
At minimum annually and whenever there is a significant change to your payment environment. Scope creep is one of the most common causes of compliance failures — systems that were added to the environment without proper segmentation or control implementation.
