A technical guide to data discovery, data protection, access control, breach detection and implementation readiness
India’s Digital Personal Data Protection (DPDP) Act, 2023 and Digital Personal Data Protection Rules, 2025 mark a significant shift in the way organisations govern digital personal data. For IT and cybersecurity teams, the challenge is not limited to defending servers and networks: it includes understanding where personal data is stored, who can access it, how it moves, how long it is retained, and whether a breach can be investigated and reported.
An organisation can have modern firewalls, endpoint security, cloud infrastructure and backups—and still have critical gaps in DPDP readiness. Infrastructure security and personal data protection overlap, but they are not identical.
Vays Infotech supports the technical side of DPDP readiness: assessing exposure, identifying gaps in existing tools, designing controls, implementing integrations and helping customers sustain evidence-based operations.
What does the DPDP framework require?
The Act covers digital personal data within its statutory scope, including information collected offline and subsequently digitised, and can extend to certain processing outside India connected with offering goods or services to individuals in India. Data Fiduciaries have obligations concerning lawful processing, notice, rights, safeguards, breach intimation and erasure. The 2025 Rules add operational details.
The 2025 Rules were notified on 13 November 2025 with phased commencement. Major operational requirements are scheduled to begin 18 months after that date, while certain provisions commenced earlier. Businesses should verify which provisions are in force before publication or implementation decisions.
1. Data discovery: can you identify where personal data exists?
Personal information can be duplicated across production databases, ERP and CRM platforms, Microsoft 365, shared drives, email attachments, endpoint downloads, cloud snapshots, development systems and third-party SaaS products. An infrastructure inventory does not reveal which of these repositories contain personal data.
Data Security Posture Management (DSPM) and data discovery capabilities can help identify sensitive records using pattern recognition, metadata, fingerprinting, contextual classification and supported content inspection. Detection of a personal identifier alone is insufficient: data owners, business purpose, retention obligations and exposure paths must also be recorded.
|
|
| Data category | Is it customer, employee, supplier or other personal data? |
| Storage and processing | Where are primary, replicated and exported copies? |
| Data ownership | Who has business responsibility for the information? |
| Access exposure | Which users, services and third parties can access it? |
| Protection | Are encryption, masking and restrictions correctly applied? |
| Retention | Which lawful retention and deletion conditions apply? |
Vays opportunity: discovery and classification assessments, DSPM integration, exposure reviews and prioritised remediation plans.
2. Identity and access: who can read or export the data?
Excessive permissions often arise from inherited file-share access, stale accounts, broad administrator roles and unrestricted application service identities. Customer data may be accessible to identities that have no continuing business need for it.
- Identity and Access Management (IAM): centralised identities, MFA, conditional access and role-based entitlements.
- Privileged Access Management (PAM): time-bound administrative access, session monitoring and credential safeguards.
- Non-human identity security: review service principals, OAuth grants, API tokens, workload identities and database accounts.
- Permission analytics: discover open shares, orphaned accounts, dormant rights and excessive privileges.
Vays opportunity: IAM/PAM assessments and implementation, least-privilege remediation, ZTNA integration and periodic identity access reviews.
3. Data Loss Prevention: where can personal data travel?
Users can export data through email, removable media, personal cloud storage, collaboration tools, external APIs or generative AI services without malware being involved. DLP controls can inspect data at rest, in motion and in use, depending on the enforcement technology.
Modern DLP policies can combine exact-data matching, document fingerprinting, contextual rules and classification tags with monitor, warn, justify, quarantine or block actions. DLP cannot independently determine whether processing has a lawful basis; business governance and application context remain necessary.
Vays opportunity: endpoint, email, web and cloud DLP policy design; pilots; false-positive tuning; and integration with security operations.
4. Encryption, masking and key management
Encryption at rest and TLS in transit are necessary layers, but encrypted storage does not prevent an authorised yet overprivileged account from exporting sensitive information. Review database and endpoint encryption, certificate hygiene, HSM/KMS administration, key rotation, secrets management, tokenisation and masking of non-production records.
Vays opportunity: architecture review, encryption control validation, secrets and key-management improvements, and secure handling of development and test data.
5. Breach detection, technical evidence and incident response
The DPDP breach-intimation framework requires technical visibility into affected systems, categories of information and individuals, timing and remedial steps. Under Rule 7, when operative, affected Data Principals and the Board must receive initial intimation without delay, with specified further information to the Board within 72 hours unless extended as permitted. Separate CERT-In reporting requirements can also apply to qualifying incidents, including a six-hour reporting obligation under applicable directions.
- SIEM: correlate endpoint, identity, network, database, SaaS and cloud audit logs.
- XDR/EDR: investigate endpoint compromises and suspicious identity activity.
- Data access monitoring: detect bulk exports, unusual downloads and inappropriate access.
- Forensic readiness: preserve timestamps, evidence, event correlation and chain of custody.
- Playbooks: tie technical incident classification to legal, privacy and communications review.
Vays opportunity: telemetry assessment, SIEM/XDR integration, detection engineering, response playbooks and tabletop exercises.
6. Retention, backup and secure erasure
Deleting a primary record may leave copies in backups, archives, reporting warehouses, email, data lakes and non-production systems. A documented architecture should map data lifecycles, erasure triggers, legally required retention, deletion propagation, backup expiry and restoration workflows.
Rule 6 contains a specific safeguard about retaining specified logs and personal data for at least one year for listed security purposes, subject to other applicable laws. This must be interpreted alongside the Act’s erasure rules and is not a general license for indefinite retention.
Vays opportunity: review backup architecture, implement technical deletion workflows, improve retention governance and verify controls through testing.
7. Third-party processors and application integrations
Outsourced payroll, SaaS applications, managed infrastructure and API integrations widen the data exposure surface. Data Fiduciaries remain responsible for relevant processing carried out on their behalf; contracts should be supported by enforceable security controls.
- Inventory shared data, integration endpoints, processors and subprocessors.
- Restrict API scopes, service account privileges and externally accessible paths.
- Validate encryption, audit logs, processor incident communication and secure offboarding.
- Test data return and erasure mechanisms when a processor relationship ends.
Vays opportunity: processor-side technical reviews, API security, segmentation, identity hardening and logging integration. Legal counsel should advise on contractual sufficiency.
8. DPDP and enterprise AI: protect prompts, retrieval and vector stores
Employees may submit personal records to public AI services; enterprise assistants may retrieve documents from repositories with excessive permissions. Retrieval-Augmented Generation (RAG) can reproduce sensitive data from indexed documents if source access restrictions are not maintained.
- Discover sensitive data in AI datasets, prompts, logs, documents and vector repositories.
- Use AI-aware DLP and approved gateways to reduce unauthorised disclosure.
- Preserve user-level entitlements during search and retrieval.
- Control API identities and policy enforcement at application and model gateways.
- Apply retention and deletion policies to prompts, results, embeddings and caches where relevant.
Vays opportunity: AI data exposure review, security gateway integration and secure infrastructure design for enterprise AI.
9. Translating DPDP obligations into technical controls

Ten questions CIOs and CISOs should ask
- Do we know where personal data is held across cloud, SaaS, on-premises and endpoints?
- Which people and service identities can access or export that data?
- Can we detect unauthorised transfers to email, cloud drives or AI tools?
- Are sensitive repositories encrypted and are keys appropriately controlled?
- Can we detect bulk downloads or anomalous data access?
- Can we identify which personal data was affected by an incident?
- Is our event evidence sufficient for the applicable breach-reporting workflow?
- Can erasure requests reach connected applications and residual copies?
- Do third-party integrations have appropriate security controls?
- Can we demonstrate through testing that protections work?
Frequently asked questions
What is the DPDP Act?
India’s Digital Personal Data Protection Act, 2023 governs processing of digital personal data within its scope and creates duties for Data Fiduciaries and rights for Data Principals.
Are the 2025 Rules already in force?
They have phased commencement. Check the government’s notified schedule for each provision; major operational provisions are scheduled for 18 months after 13 November 2025.
Is ISO 27001 certification enough?
No. ISO/IEC 27001 can support security governance but is not by itself a determination of DPDP compliance.
Does DPDP mandate DLP or DSPM?
Not by those universal product names. These are useful implementation methods for certain safeguards.
Does every organisation need a statutory Data Protection Officer?
Section 10 imposes a DPO obligation on notified Significant Data Fiduciaries. Other organisations may have different applicable contact and grievance obligations.
How fast must a personal data breach be reported?
Rule 7 provides for initial intimation without delay and specified further Board information within 72 hours, when applicable. Other reporting duties may also apply.
Can existing security tools help?
Often yes. The essential issue is whether they are correctly configured, integrated and operated to address personal data risk.
What does Vays do?
Vays provides technical assessments and implementation support involving discovery, classification, identity, DLP, monitoring, encryption and operational security controls.
Conclusion: make data protection operational
Policies alone cannot establish where personal data resides, prevent unauthorised exports or reconstruct a breach. Organisations need visibility, technical enforcement, reliable logs, defined accountability and continuing validation.
Vays Infotech helps customers move from technical gap identification to implementation and ongoing operation of stronger personal data safeguards. It supports DPDP readiness; legal interpretations and final compliance determinations remain with the organisation and qualified advisers.
