Organizations increasingly depend on third-party service providers to manage customer information, employee records, payment transactions, cloud infrastructure, marketing operations, customer support, analytics, and business applications. These providers may process significant volumes of digital personal data on behalf of an organization, creating additional privacy, cybersecurity, and compliance risks.

Under India’s Digital Personal Data Protection Act, 2023 (DPDP Act), organizations that determine the purpose and means of processing personal data are generally referred to as Data Fiduciaries. Entities processing personal data on behalf of Data Fiduciaries are known as Data Processors. The involvement of a Data Processor does not eliminate the Data Fiduciary’s responsibility to establish appropriate controls over personal data processing.

The DPDP Rules, 2025 require Data Fiduciaries to implement reasonable security safeguards for personal data in their possession or control, including processing carried out by Data Processors. The Rules also identify the need for appropriate security provisions in contracts between Data Fiduciaries and Data Processors.

Third-party risk management under the DPDP framework therefore requires more than signing a data processing agreement. Organizations should assess vendors before onboarding, define contractual responsibilities, restrict access, monitor security performance, manage data retention, prepare for incidents, and periodically reassess third-party risks.

This article explains how businesses can establish a practical third-party risk management programme aligned with DPDP requirements and broader cybersecurity objectives.

What Is DPDP Third-Party Risk Management?

DPDP third-party risk management is the structured process of identifying, assessing, controlling, monitoring, and reducing privacy and security risks arising from external organizations that process or access personal data.

Third parties may include cloud service providers, SaaS platforms, payment gateways, CRM providers, HR software vendors, marketing agencies, customer support companies, analytics providers, IT service providers, managed security providers, and outsourced business process operators.

These organizations may process personal data directly or indirectly. For example, a CRM provider may store customer contact information, while a customer support vendor may access customer complaints and account details. A cloud provider may host databases containing personal data without directly deciding the business purpose for which the data is collected.

Third-party risk management helps an organization understand what information is shared, why it is shared, where it is stored, who can access it, and what happens when the relationship ends.

A strong programme should address both privacy risk and cybersecurity risk. A vendor may have appropriate privacy documentation but inadequate access controls. Similarly, a vendor may maintain strong technical security but process personal data beyond the agreed business purpose.

Why Third-Party Risk Management Matters Under the DPDP Act

Modern organizations rarely operate entirely within their own technology environments. Business applications, cloud infrastructure, outsourced operations, and digital platforms often depend on multiple service providers.

This interconnected model can increase the organization’s attack surface. A security weakness at one vendor may expose personal data belonging to the organization’s customers, employees, suppliers, or other individuals.

For example, a company may use a third-party marketing platform to manage customer leads. If the platform experiences unauthorized access, customer names, email addresses, phone numbers, or communication preferences may be exposed. Even if the company’s internal systems were not directly compromised, the incident could still create privacy, contractual, reputational, and operational consequences.

Third-party risks can also arise from excessive access, unclear data retention, inadequate breach notification processes, insecure integrations, subcontractors, weak authentication, and the use of personal data for purposes not authorized by the organization.

The DPDP framework makes it important for Data Fiduciaries to understand how personal data is processed on their behalf and whether appropriate safeguards are implemented throughout the processing lifecycle.

Understanding Data Fiduciaries and Data Processors

Data Fiduciary

A Data Fiduciary is an entity that determines the purpose and means of processing personal data. This may include a business, institution, platform, or organization that collects personal data from customers, employees, users, applicants, or other individuals.

The Data Fiduciary determines why the data is required, how it will be used, which systems will process it, and which external providers may receive access.

For example, an e-commerce company may determine that customer information is required to process orders, provide support, manage returns, and communicate service updates. The company may engage external providers to support these activities, but it remains responsible for governing the overall processing relationship.

Data Processor

A Data Processor processes personal data on behalf of a Data Fiduciary. Examples may include cloud hosting providers, payroll service providers, customer support platforms, outsourced processing companies, and technology vendors.

A Data Processor may provide essential services without determining the organization’s primary purpose for collecting the information. However, the specific nature of a relationship should be assessed based on the actual responsibilities and activities of the parties.

Organizations should document whether a vendor acts as a Data Processor, independently determines processing purposes, or performs different roles for different services.

Why the Distinction Matters

The distinction helps organizations establish appropriate contracts, responsibilities, security controls, and oversight arrangements. It also supports accountability when personal data moves across multiple systems or service providers.

A vendor classification should not be based only on the vendor’s marketing description. Businesses should assess the actual data flows, processing activities, decision-making responsibilities, and contractual terms.

Create a Complete Third-Party Data Inventory

The first step in third-party risk management is identifying all external organizations that process or access personal data.

Many businesses have incomplete vendor inventories because procurement records, IT asset lists, privacy documentation, and business department records are maintained separately. Some vendors may also be onboarded directly by individual departments without central approval.

A third-party data inventory should identify the vendor’s legal name, service provided, business owner, data categories, affected individuals, processing purpose, systems involved, geographic locations, access permissions, subcontractors, retention period, and contract status.

The inventory should cover both major strategic vendors and smaller providers. A low-cost SaaS application may still process sensitive customer information or connect to internal systems.

Organizations should also identify shadow vendors and unauthorized tools. Employees may use online file-sharing services, AI applications, survey platforms, or productivity tools without involving procurement or security teams.

A reliable third-party inventory allows the organization to understand its external data exposure and prioritize vendor assessments based on risk.

Recommended Third-Party Inventory Fields

The inventory should include the vendor name, service description, business owner, processing purpose, personal data categories, Data Principal categories, systems accessed, access type, data location, subcontractors, contractual safeguards, retention requirements, security certifications, incident contact details, assessment status, and relationship termination date.

The information should be reviewed periodically because vendors may change their services, infrastructure, subcontractors, data locations, or security practices.

Classify Vendors Based on Risk

Not all third parties present the same level of privacy and cybersecurity risk. Organizations should establish a risk-based vendor classification model instead of applying identical assessment requirements to every provider.

A vendor that only receives limited business contact information may present a different risk from a provider hosting customer identity records, employee information, financial data, or authentication credentials.

Vendor classification should consider the sensitivity of the personal data, volume of information, number of affected individuals, access privileges, business criticality, integration complexity, geographic exposure, subcontractor involvement, and consequences of a potential breach.

Low-Risk Vendors

Low-risk vendors may have limited access to personal data or provide services that do not involve sensitive processing. However, the organization should still document the relationship and establish basic contractual and security requirements.

Medium-Risk Vendors

Medium-risk vendors may process personal data regularly or connect to business applications. These providers should generally undergo a structured security and privacy assessment, contractual review, and periodic reassessment.

High-Risk Vendors

High-risk vendors may host large datasets, process sensitive information, provide critical business services, or maintain privileged access to internal systems. These providers may require enhanced due diligence, technical validation, stronger contractual controls, incident response coordination, and more frequent monitoring.

Risk classification should be reviewed whenever the scope of processing changes, a new integration is introduced, or the vendor experiences a security incident.

Conduct Vendor Due Diligence Before Onboarding

Third-party risk management should begin before a vendor receives access to personal data. Procurement and business teams should coordinate with privacy, legal, IT, and cybersecurity stakeholders during the onboarding process.

Vendor due diligence should examine whether the provider has appropriate policies, security controls, access management, incident response capabilities, business continuity measures, and privacy practices.

A vendor questionnaire may address authentication, encryption, vulnerability management, logging, employee access, backup protection, incident reporting, subcontractors, data deletion, and security testing.

Organizations should not rely solely on a completed questionnaire. Vendor responses should be reviewed against the organization’s risk requirements and, where appropriate, supported by evidence such as audit reports, independent assessment results, certifications, security documentation, or technical validation.

The level of due diligence should be proportionate to the risk. A vendor handling large amounts of personal data or accessing critical infrastructure should undergo a more detailed review than a provider with minimal access.

Evaluate Vendor Data Processing Activities

Organizations should determine exactly how each vendor processes personal data. A vendor may perform multiple activities, and the risk may differ between services.

The assessment should establish:

• What personal data is collected or received.
• Why the vendor processes the data.
• Whether processing is necessary for the agreed service.
• Where the data is stored.
• Which employees or systems can access it.
• Whether the data is shared with subcontractors.
• How long the data is retained.
• How the data is deleted or returned.
• Whether the vendor uses the data for analytics, profiling, AI training, or other secondary purposes.

These questions should be documented rather than handled only through informal communication.

For example, a business may appoint a customer support provider to respond to service requests. The contract may permit access to customer names, contact details, and order information. However, the vendor should not automatically have unrestricted access to unrelated financial records, identity documents, or internal employee information.

The organization should apply purpose limitation and least-privilege principles to ensure that the vendor receives only the information and access necessary for the contracted service.

Establish Strong Data Processing Agreements

A data processing agreement or equivalent contractual arrangement should clearly define the responsibilities of the Data Fiduciary and Data Processor.

The contract should be aligned with the actual processing activities and should not rely on generic language that fails to address important operational risks.

Relevant contractual provisions may cover:

Purpose and Scope

The agreement should specify the services being provided, the categories of personal data involved, the affected individuals, and the purposes for which the vendor may process the information.

Processing Instructions

The vendor should process personal data according to documented instructions and agreed purposes. Any significant change in processing should require appropriate review and approval.

Security Safeguards

The agreement should require reasonable technical and organizational safeguards appropriate to the risks. The DPDP Rules, 2025 specifically refer to appropriate security provisions in contracts between Data Fiduciaries and Data Processors.

Confidentiality

The vendor should ensure that personnel with access to personal data are subject to confidentiality obligations and receive appropriate training.

Access Controls

The agreement should address role-based access, privileged accounts, authentication, access reviews, and the removal of access when personnel change roles or leave the vendor.

Incident Notification

The contract should define how and when the vendor must report suspected or confirmed security incidents to the Data Fiduciary. It should also require cooperation during investigation, containment, evidence collection, and remediation.

Subcontracting

The vendor should disclose relevant subcontractors and define the approval, oversight, and security requirements applicable to them.

Audit and Assurance

The agreement should establish appropriate rights to obtain security evidence, review compliance, request remediation, or conduct assessments based on risk and contractual requirements.

Data Return and Deletion

The contract should define how personal data is returned, deleted, or securely disposed of when the service ends or the data is no longer required.

Apply Data Minimization and Least Privilege

Third-party access should be restricted to the minimum data and permissions required to perform the contracted service.

Excessive access can increase the impact of a compromised vendor account, insider misuse, or accidental disclosure. Organizations should avoid providing broad access merely because it is technically convenient.

For example, a payroll provider may require employee salary and bank information for payroll processing, but it may not need access to customer marketing databases. Similarly, a customer support vendor may need access to order and service records but not unrestricted administrative access to the company’s production environment.

Access controls should be implemented through role-based permissions, separate accounts, multi-factor authentication, privileged access management, network restrictions, and periodic access reviews.

Organizations should also assess whether vendor accounts are shared. Shared credentials reduce accountability and make it difficult to determine which individual performed an action.

Third-party access should be reviewed when the scope of work changes, the contract is renewed, an employee leaves the vendor, or a security incident occurs.

Review Vendor Security Safeguards

The DPDP Rules, 2025 identify several security safeguard categories relevant to the protection of personal data. These include encryption or similar data protection measures, access controls, logs and monitoring, business continuity measures, retention of relevant logs and personal data for specified purposes, contractual security provisions, and technical and organizational measures.

Organizations should evaluate whether vendors have controls appropriate to the services they provide.

Encryption

The vendor should protect personal data during transmission and, where appropriate, at rest. Encryption key management should also be reviewed because encrypted data may remain exposed if keys are improperly managed.

Access Management

The vendor should implement appropriate identity controls, privileged access restrictions, multi-factor authentication, and periodic access reviews.

Logging and Monitoring

The vendor should maintain relevant logs that support detection, investigation, and remediation of unauthorized access. The organization should determine whether it can obtain necessary logs during an incident.

Vulnerability Management

Vendors should maintain a process for identifying, prioritizing, remediating, and validating vulnerabilities. Critical services should be assessed based on their exposure and business impact.

Backup and Recovery

Vendors should maintain appropriate backup and recovery procedures for systems supporting personal data processing. Businesses should understand recovery objectives and the vendor’s ability to continue services following an outage or security incident.

Employee Security

Vendor personnel should receive security awareness training and should only receive access appropriate to their responsibilities.

The organization should document the evidence reviewed and identify gaps requiring remediation or risk acceptance.

Assess Cloud and SaaS Providers

Cloud and SaaS providers often process personal data at scale and may be deeply integrated into business operations. Their risks require specific attention.

Organizations should identify the cloud services used, the geographic location of data, the identity model, administrative access, storage permissions, logging capabilities, backup arrangements, and shared responsibility boundaries.

The shared responsibility model should be clearly understood. A cloud provider may secure parts of the underlying infrastructure, while the customer remains responsible for configuration, identity permissions, application security, data classification, and access management.

SaaS providers may also introduce risks through integrations, APIs, browser extensions, plugins, and connected applications. Businesses should assess whether the vendor’s platform can access more information than required.

Before onboarding a cloud or SaaS provider, the organization should confirm how data is isolated, protected, retained, deleted, and recovered. It should also identify the process for handling service termination and account closure.

Manage Vendor Subcontractors and Fourth Parties

A vendor may engage additional providers to deliver its services. These subcontractors can create a fourth-party risk because the organization may not have direct visibility into how its personal data is processed further downstream.

For example, a customer support provider may use a separate cloud hosting platform, communication provider, analytics service, or ticketing platform. Each additional dependency may introduce new access paths and operational risks.

Contracts should require vendors to disclose relevant subcontractors and maintain appropriate oversight of their security and privacy practices.

Organizations should assess whether subcontractors process personal data, where they are located, what access they receive, and whether the primary vendor remains accountable for their activities.

A vendor’s use of subcontractors should not be treated as an administrative detail. It should be incorporated into the organization’s data-flow mapping and third-party risk assessment process.

Establish Vendor Data Retention and Deletion Controls

Personal data should not be retained indefinitely by third-party providers without a documented business, legal, or operational reason.

Organizations should define retention requirements based on the purpose of processing, contractual terms, applicable legal requirements, and internal data governance policies.

The vendor should identify where data is stored, including primary systems, backups, archives, logs, test environments, and disaster recovery systems. Deletion requirements should address these environments where applicable.

Businesses should also define how deletion is verified. A vendor’s statement that data has been deleted may not be sufficient for high-risk processing activities. Depending on the circumstances, the organization may require a deletion certificate, system confirmation, audit evidence, or other reasonable assurance.

Data retention should be reviewed during contract renewals and when services are modified. If a vendor no longer requires access to specific data, the access and data should be removed according to documented procedures.

Prepare for Third-Party Data Breaches

A vendor-related data breach can create complex response requirements because the incident may involve multiple organizations, systems, and jurisdictions.

The Data Fiduciary should establish a process for receiving timely notifications from vendors. The contract should identify escalation contacts, reporting channels, required information, and cooperation expectations.

When a vendor reports an incident, the organization should determine whether its own systems or data were affected. The response team should seek information about the incident’s nature, timeline, affected systems, data categories, containment actions, investigation findings, and remediation status.

The organization should not automatically assume that a vendor’s preliminary assessment represents the complete scope of the incident. Initial findings may change as forensic investigation progresses.

The response should involve cybersecurity, privacy, legal, business, communications, and vendor management teams. Depending on the incident and applicable requirements, the organization may need to assess notification obligations, contractual commitments, customer communication, and regulatory reporting.

The DPDP Rules, 2025 contain requirements relating to intimation of personal data breaches, including communication with affected Data Principals and the Data Protection Board. Organizations should verify the applicable commencement position and current legal requirements when responding to an incident.

Integrate Vendor Risk With Incident Response

A third-party risk programme should connect directly with the organization’s incident response plan.

The incident response plan should identify which vendors support critical systems, who must be contacted during an incident, and how access can be restricted or revoked.

Organizations should maintain an updated vendor incident contact list, including primary and backup contacts. Contact details should be verified periodically because outdated information can delay containment and investigation.

The plan should address scenarios such as:

• A cloud provider experiencing a ransomware attack.
• A CRM provider reporting unauthorized access.
• A payment processor exposing transaction-related information.
• A SaaS platform suffering an account takeover.
• A vendor employee accessing personal data without authorization.
• A subcontractor experiencing a security incident.
• A third-party API exposing personal data through an authorization flaw.

Tabletop exercises should include vendors where practical. These exercises can reveal communication gaps, unclear responsibilities, unavailable logs, and weaknesses in escalation procedures.

Conduct Technical Security Assessments of Vendors

Contractual assurances and questionnaires may not fully demonstrate whether a vendor’s systems are secure. Technical assessments can provide additional evidence for higher-risk relationships.

The assessment approach should be based on the vendor’s service, architecture, access privileges, and data exposure.

Potential activities include reviewing security architecture, evaluating API security, testing authentication and authorization controls, assessing cloud configurations, reviewing vulnerability management processes, and examining logging and monitoring capabilities.

Where contractually permitted, organizations may conduct or commission penetration testing of relevant integrations and systems. Testing should be scoped carefully to avoid disrupting the vendor’s operations or violating contractual restrictions.

For customer-facing applications, API security is particularly important. An insecure integration may expose personal data even when the vendor’s main platform has strong controls.

Organizations should track identified findings, assign remediation deadlines, and validate corrective actions. High-risk findings should be escalated to appropriate management stakeholders.

Evaluate Vendor Security Certifications and Audit Reports

Security certifications and independent audit reports can support vendor due diligence, but they should not be treated as complete substitutes for risk assessment.

Organizations should examine the scope, date, control coverage, exclusions, and applicability of the evidence provided. A certification may cover only a specific service, geographic region, or infrastructure environment.

Businesses should determine whether the assessment covers the systems that process their personal data and whether the controls remain relevant to the contracted service.

Evidence may include independent assurance reports, security certifications, penetration testing summaries, vulnerability management reports, business continuity test results, and incident response exercise findings.

Where a vendor cannot provide independent assurance, the organization should evaluate alternative evidence and determine whether additional safeguards or contractual protections are required.

Monitor Vendor Performance Continuously

Third-party risk management should not end after onboarding. A vendor’s security posture may change due to new services, mergers, acquisitions, infrastructure changes, subcontractors, personnel changes, or security incidents.

Organizations should establish a monitoring programme based on vendor risk classification.

Monitoring may include periodic questionnaires, evidence reviews, contract compliance checks, access reviews, incident performance evaluations, security alerts, and reassessment following significant changes.

High-risk vendors may require more frequent reviews than low-risk providers. The organization should also conduct an assessment when a vendor introduces new processing purposes, connects a new system, expands geographic coverage, or changes its data retention practices.

Vendor performance should be reported through appropriate governance channels. Unresolved risks should be recorded in the risk register, assigned owners, and tracked until closure or formally accepted by authorized management.

Establish Vendor Risk Governance and Accountability

Third-party risk management requires collaboration across multiple teams.

Executive leadership should oversee significant vendor-related risks and ensure that the organization has adequate resources for managing critical service providers.

The privacy and compliance team should review DPDP-related responsibilities, processing purposes, data protection requirements, and documentation.

Cybersecurity should evaluate technical safeguards, access controls, monitoring, vulnerabilities, and incident response capabilities. IT teams should manage integrations, infrastructure dependencies, and access provisioning.

Legal teams should review contractual terms, liability provisions, confidentiality obligations, data processing responsibilities, and termination requirements. Procurement should coordinate vendor onboarding, due diligence, renewal, and contractual documentation.

Business owners should remain accountable for the vendors supporting their processes. They should understand what data is shared, why the service is required, and whether the vendor continues to meet business and security requirements.

A responsibility matrix should identify who approves vendors, who performs assessments, who accepts risks, who monitors performance, and who coordinates incident escalation.

Implement a Vendor Risk Scoring Framework

A vendor risk scoring framework helps organizations prioritize resources and identify providers requiring additional controls.

The scoring model should be documented and applied consistently. It may consider the following factors:

Risk FactorAssessment ConsiderationData SensitivityType and sensitivity of personal dataData VolumeNumber of records or individuals affectedAccess PrivilegesLevel of system and administrative accessBusiness CriticalityImpact if the service becomes unavailableIntegration ExposureAPIs, connections, and data exchangeGeographic RiskData locations and processing jurisdictionsSubcontractorsNumber and nature of downstream providersSecurity MaturityPolicies, controls, testing, and assuranceIncident HistoryRelevant past security incidentsRetentionDuration and complexity of data retention

The scoring model should support decision-making rather than create a false impression of precision. A vendor with a low numerical score may still present a serious risk if it has privileged access to a critical system.

Organizations should document the rationale behind risk ratings and review them when circumstances change.

Manage Vendor Offboarding

Vendor offboarding is an important but frequently overlooked part of third-party risk management.

When a contract ends, the organization should ensure that the vendor’s access is revoked, personal data is returned or deleted, credentials are disabled, integrations are removed, and outstanding security issues are addressed.

Offboarding should cover active systems as well as backups, archives, test environments, support tools, and shared storage where relevant.

The organization should confirm whether the vendor has retained any copies of personal data and whether contractual or legal retention requirements apply.

A formal offboarding checklist should assign responsibilities to business owners, IT, cybersecurity, procurement, legal, and the vendor. Evidence of access removal and data deletion should be retained according to internal governance requirements.

Offboarding should also be triggered when a vendor is replaced, a service is discontinued, or the scope of processing is reduced.

Third-Party Risk Management for AI Vendors

AI platforms and AI-enabled service providers introduce additional third-party risk considerations. Organizations may use external AI tools for customer support, document processing, analytics, coding, recruitment, marketing, or internal productivity.

Before using an AI vendor, businesses should determine whether personal data is processed by the platform, whether prompts and uploaded files are retained, whether data is used for model training, which subprocessors are involved, and how access is controlled.

Organizations should also review the vendor’s approach to data isolation, model security, logging, deletion, data residency, and incident response.

AI integrations may expose personal data through prompts, connectors, APIs, browser extensions, plugins, or automated agents. Third-party risk assessments should therefore include the full AI data flow rather than only the primary application.

Businesses should establish acceptable-use policies and restrict the submission of personal data to unauthorized AI services. AI vendor assessments should be updated when the vendor changes its model, processing terms, hosting arrangements, or connected tools.

Third-Party Risk Management for Cloud and APIs

Cloud platforms and APIs are common sources of third-party exposure because they connect internal systems to external infrastructure and services.

Organizations should document the information exchanged through each integration and verify that authentication and authorization controls are correctly implemented.

API assessments should evaluate whether users can access information belonging to other users, whether tokens are securely managed, whether endpoints expose excessive information, and whether rate limits and monitoring are implemented.

Cloud assessments should examine identity permissions, storage access, security configurations, logging, backup protection, and network exposure.

Where personal data moves between multiple providers, the organization should maintain a data-flow map showing the source, destination, purpose, and security controls for each transfer.

Common Third-Party Risk Management Mistakes

Relying Only on Questionnaires

A questionnaire may provide useful information, but vendor responses should be validated through relevant evidence and risk-based assessments.

Using Generic Contracts

A generic agreement may not address the organization’s specific data categories, processing activities, incident requirements, subcontractors, or deletion obligations.

Ignoring Subcontractors

Downstream providers may introduce additional access and processing risks. Subcontractor oversight should be included in the vendor governance programme.

Failing to Review Access

Vendor access may remain active after a project ends, an employee leaves, or the scope of work changes. Periodic access reviews are essential.

Neglecting Offboarding

Organizations may revoke primary accounts but overlook integrations, backups, shared credentials, or retained copies of personal data.

Treating Certifications as Complete Assurance

A certification may not cover the specific service or systems used by the organization. Scope and control coverage should be reviewed carefully.

Not Testing Incident Response

A vendor breach response plan may fail if contact information is outdated or responsibilities are unclear. Regular exercises can identify these weaknesses.

Ignoring Shadow SaaS and AI Tools

Employees may introduce unauthorized applications that process personal data outside approved governance channels. Discovery and monitoring processes should address this risk.

DPDP Third-Party Risk Management Checklist

Organizations can use the following checklist to evaluate their third-party risk management programme:

1. Maintain a complete inventory of third parties processing personal data.
2. Identify the Data Fiduciary and Data Processor relationship.
3. Document data categories and processing purposes.
4. Map data flows between internal systems and vendors.
5. Classify vendors according to risk.
6. Conduct due diligence before onboarding.
7. Review vendor security policies and supporting evidence.
8. Establish appropriate contractual security safeguards.
9. Define incident reporting and escalation requirements.
10. Restrict vendor access using least-privilege principles.
11. Implement multi-factor authentication for relevant access.
12. Review vendor subcontractors and downstream providers.
13. Define retention, return, and deletion requirements.
14. Assess cloud, API, and integration security.
15. Review vulnerability management and penetration testing practices.
16. Maintain emergency vendor contact details.
17. Conduct periodic reassessments based on risk.
18. Track unresolved findings through a risk register.
19. Test vendor incident response coordination.
20. Complete formal offboarding and verify access removal.
21. Review AI vendors and third-party AI integrations.
22. Report significant third-party risks to management.

The checklist should be adapted to the organization’s size, industry, data processing activities, and applicable legal requirements.

Conclusion

Third-party risk management under the DPDP Act requires organizations to understand and control how external service providers process personal data. Vendor relationships should be managed through a combination of due diligence, contractual safeguards, access restrictions, security assessments, continuous monitoring, incident response coordination, and formal offboarding.

Businesses should not assume that a vendor’s involvement removes their accountability for personal data protection. The organization must understand its data flows, processing purposes, security dependencies, and contractual responsibilities.

A mature third-party risk management programme helps reduce the likelihood of unauthorized access, excessive data exposure, vendor-related breaches, and compliance gaps. It also improves operational resilience by ensuring that organizations can respond effectively when an external provider experiences a security incident.

DPDP readiness should therefore include third-party governance as a core component of the organization’s privacy, cybersecurity, and enterprise risk management strategy.
