ISO 27018 in India – Public Cloud PII Protection, DPDP & Cloud Security- Get certified with SCS

https://scscertification.com/contactus.php

Indian businesses are using cloud platforms for customer applications, software services, financial technology, healthcare systems, employee platforms and outsourced business processes. As more personal information moves through these environments, customers increasingly want to understand how a cloud provider protects that information and manages its responsibilities as a processor.

ISO/IEC 27018:2025 is specifically relevant to this question.

The current standard provides guidance for protecting personally identifiable information (PII) in public-cloud services where the cloud service provider acts as a PII processor. ISO describes it as an extension of ISO/IEC 27002 for cloud-based PII processing and says it complements an ISO/IEC 27001-based information security management system (ISMS). The 2025 edition was published in August 2025 and replaced the withdrawn 2019 edition.

For an Indian SaaS provider, managed cloud company, BPO, fintech technology business, healthcare platform or other cloud service provider, ISO 27018 can provide a structured way to address cloud-specific PII protection.

It should, however, be considered alongside Indian legal, contractual and customer requirements. ISO 27018 does not replace the Digital Personal Data Protection Act or applicable CERT-In directions.

What Is ISO/IEC 27018:2025?

ISO/IEC 27018:2025 is an international guideline for protecting PII in public-cloud environments when the cloud service provider acts as a PII processor.

Its focus is narrower than a general information-security management system. The standard is concerned with the practical privacy and security issues that arise when a cloud provider handles personal information on behalf of another organization.

ISO identifies areas including:

• PII protection in public-cloud processing

• Responsibilities between cloud providers and customers

• Transparency and accountability

• Auditability

• Contractual and regulatory considerations

• Protection of PII through its processing lifecycle

• Cloud-specific privacy risks

The standard covers PII handled by public-cloud providers on behalf of customers, including collection, storage, processing, transmission and deletion.

What Changed with ISO 27018:2025?

Businesses researching ISO 27018 in India will still find references to ISO/IEC 27018:2019 online. That edition has been withdrawn.

ISO/IEC 27018:2025 is now the current edition. ISO records show that Edition 3 was published on 26 August 2025. It has been aligned with ISO/IEC 27002:2022 and includes a new Annex B with additional implementation guidance.

For a new Indian cloud privacy programme, it therefore makes sense to assess the current 2025 edition rather than simply reproducing requirements from older 2019 material.

Who Should Consider ISO 27018 in India?

ISO 27018 is most relevant to public-cloud service providers acting as PII processors. It can also be useful to organizations evaluating cloud providers and the safeguards applied to outsourced PII processing.

In India, potential users and interested organizations include:

• Public-cloud service providers

• SaaS companies

• Cloud hosting businesses

• Managed service providers

• Data-centre and cloud operators

• IT outsourcing companies

• BPO and KPO providers

• Fintech technology companies

• Healthcare technology providers

• E-commerce platforms

• Telecommunications technology providers

• Global Capability Centres

• Enterprise application providers

The sector by itself does not establish applicability. The more useful question is whether the organization's public-cloud service processes PII in the role addressed by the standard.

ISO 27018 and Public-Cloud PII Protection

Consider an Indian SaaS company providing HR software to corporate customers.

Its application may contain employee names, contact details, identification information and other customer-controlled data. The application may run on a public-cloud platform, while the SaaS provider manages the application and related services.

Several questions immediately arise:

Who can access production data?

How is administrator access controlled?

What happens when a customer closes its account?

Which suppliers can access the environment?

How are incidents handled?

What information is retained?

How is customer data deleted or returned?

These are practical cloud-processing questions. ISO 27018 provides guidance for addressing the PII-protection aspects of that environment.

ISO 27018 and ISO 27001 in India

ISO 27018 should not be treated as a replacement for ISO 27001.

The two standards have different roles.

ISO/IEC 27001 provides requirements for an Information Security Management System.

ISO/IEC 27018:2025 provides cloud-specific guidance for protecting PII in public-cloud services where the provider acts as a processor.

ISO specifically states that ISO 27018 complements an ISO 27001-based ISMS.

This means an Indian cloud provider may use ISO 27001 as the broader information-security management framework and ISO 27018 to address relevant cloud PII-processing considerations.

For organizations researching the broader information-security certification landscape, SCS maintains a separate ISO 27001 certification resource for India.

The two pages should serve different search intents: the ISO 27001 page addresses the broader ISMS and certification subject, while this page focuses on public-cloud PII protection.

ISO 27018 and ISO 27701

ISO 27018 and ISO 27701 also have different purposes.

ISO 27018 is focused on PII protection in public-cloud services where the provider acts as a processor.

ISO 27701 addresses Privacy Information Management and has a wider privacy-management focus.

That distinction matters for Indian organizations evaluating privacy frameworks alongside the DPDP regime.

A company looking for a broader privacy-management framework should review the dedicated ISO 27701 resource for India.

This page deliberately keeps its focus on public-cloud PII processing rather than becoming another general DPDP or privacy-management article.

ISO 27018 and India's DPDP Framework

India's Digital Personal Data Protection framework is a separate legal matter.

The Digital Personal Data Protection Act, 2023 establishes the statutory framework for processing digital personal data in India. The Ministry of Electronics and Information Technology (MeitY) subsequently published the Digital Personal Data Protection Rules, 2025 and an enforcement timeline in November 2025.

ISO 27018 does not replace these legal requirements.

Instead, an organization can consider ISO 27018 when designing and demonstrating controls for public-cloud PII processing.

For example, an organization may need to understand:

• What personal data enters its cloud service

• Why the data is processed

• Which parties have access

• Which cloud providers or subprocessors are involved

• How information is retained

• How information is deleted

• How incidents are handled

• What customers have been told about the processing

The legal assessment and the ISO assessment should remain connected but should not be confused with one another.

ISO 27018 and the DPDP Rules 2025

MeitY published the Digital Personal Data Protection Rules, 2025 on 14 November 2025, together with material covering the enforcement timeline and establishment of the Data Protection Board of India.

For an Indian cloud provider, the practical exercise is to understand where personal data enters the service and how it moves through the technology environment.

A useful review can cover:

Data intake → processing → storage → access → sharing → retention → deletion

ISO 27018 can provide relevant cloud PII guidance within that process.

It should not be marketed as a blanket certification of compliance with the DPDP Act or Rules.

ISO 27018 and CERT-In

Indian cloud providers also need to consider applicable cybersecurity directions issued by the Indian Computer Emergency Response Team (CERT-In).

CERT-In publishes directions under Section 70B of the Information Technology Act, 2000 concerning information-security practices, prevention, response and reporting of cyber incidents. Its official material specifically addresses implementation matters involving data centres, VPS providers, cloud service providers and VPN service providers.

The distinction is straightforward:

ISO 27018: guidance for protecting PII in applicable public-cloud processing.

CERT-In: Indian cybersecurity directions and incident-related requirements that apply to covered entities.

One does not replace the other.

ISO 27018 and Indian Cloud Procurement

ISO 27018 also has practical relevance in Indian cloud procurement.

Government of India cloud procurement guidance lists ISO 27001, ISO 27017 and ISO 27018 among standards that user departments may require from cloud service providers. The document specifically describes ISO 27018 in relation to protection of PII in public clouds.

That does not mean every Indian cloud provider is legally required to maintain ISO 27018.

Instead, the requirement may arise from a particular tender, customer specification, contractual arrangement or cloud procurement programme.

For a provider bidding for enterprise or government work, checking the exact tender language is therefore more useful than assuming that one standard applies to every contract.

ISO 27018 for SaaS Companies in India

SaaS is one of the clearest practical applications.

An Indian SaaS provider may have thousands of users across different customer organizations. Its platform may process personal information while the underlying infrastructure is supplied by a public-cloud provider.

The provider should be able to explain how customer PII is protected across its service.

Areas for review can include:

• Production access

• Privileged accounts

• Customer-data segregation

• Supplier access

• Data retention

• Data deletion

• Incident handling

• Customer instructions

• Administrative activity

• Evidence of control operation

The wider information-security requirements of SaaS companies are addressed separately in SCS's ISO 27001 for SaaS companies resource.

ISO 27018 for Fintech Companies

Indian fintech businesses may process personal information through digital onboarding, account management, lending applications, customer support and payment-related services.

Where public-cloud services process PII for these applications, ISO 27018 may be relevant to the cloud-processing arrangement.

A fintech organization must still evaluate the regulatory and contractual requirements applicable to its particular business model.

ISO 27018 should therefore be treated as one part of the overall control environment, not as a substitute for financial-sector regulation.

ISO 27018 for Banks and Financial Services

Banks and financial institutions may use cloud services for selected applications and business functions.

Examples include:

• Customer portals

• Digital onboarding

• Document management

• Analytics

• Customer-service applications

• Internal employee platforms

• Selected technology services

Where applicable public-cloud services process PII, ISO 27018 can provide useful cloud-specific guidance.

Organizations should separately assess the RBI requirements and contractual conditions applicable to the relevant service.

ISO 27018 for Healthcare Technology in India

Healthcare technology platforms may process personal information through:

• Patient applications

• Telemedicine systems

• Appointment platforms

• Laboratory applications

• Healthcare portals

• Billing systems

• Customer-service platforms

When public-cloud services process PII for these applications, ISO 27018 can be relevant to the cloud-processing environment.

The organization's complete compliance programme may include additional contractual, legal and sector-specific obligations.

ISO 27018 for BPO and KPO Companies

India's outsourcing sector handles information for customers across many industries and countries.

A BPO or KPO operation may use cloud systems for customer service, document processing, analytics, HR operations or other outsourced activities.

If a public-cloud provider processes PII on behalf of the organization or its customers, ISO 27018 can be considered as part of the cloud-control framework.

For international customers, the organization should also review the contractual and privacy obligations attached to each engagement.

ISO 27018 for Global Capability Centres

Global Capability Centres may operate technology, finance, HR, analytics, engineering or customer-support functions for multinational parent organizations.

Cloud applications used by these teams can contain employee, customer or business-user information.

ISO 27018 can therefore be relevant when applicable public-cloud providers process PII for GCC operations.

The scope should be based on the actual service rather than the GCC label itself.

ISO 27018 for E-Commerce Companies

E-commerce systems can process personal information at several points:

Account creation → Order → Payment-related processing → Delivery → Customer support → Account management

Cloud platforms may support several of these functions.

Where a public-cloud provider acts as a PII processor, ISO 27018 can help frame the controls expected around that relationship.

ISO 27018 for Managed Cloud and Data-Centre Providers

Managed cloud providers and data-centre businesses may support customer applications containing personal information.

An assessment may examine areas such as:

• Privileged access

• Customer environment separation

• Administrative accounts

• Supplier access

• Security incidents

• PII retention

• Deletion arrangements

• Customer instructions

• Monitoring and evidence

Applicability depends on the organization's actual service and processing role.

ISO 27018 for Indian Manufacturing Businesses

ISO 27018 is not limited to technology companies.

A manufacturing organization may use cloud services for:

• Employee systems

• Recruitment

• Dealer portals

• Customer applications

• Warranty services

• Logistics platforms

• Supplier systems

If a relevant public-cloud service processes PII, the organization can evaluate ISO 27018-related requirements.

The industry itself does not make the standard mandatory.

ISO 27018 Assessment and Implementation in India

Is ISO 27018 Independently Certifiable?

This is an important point for Indian organizations using the term “ISO 27018 certification.”

ISO's current compliance material describes ISO 27018 as a code of practice and guideline rather than an independently certifiable standard. ISO states that it complements ISO 27001 certification and that cloud providers can demonstrate ISO 27018 compliance within an ISO 27001 audit.

Consequently, an organization searching for “ISO 27018 certification in India” should first determine what its customer, tender or contract actually requires.

Depending on the situation, the requirement could involve:

• ISO 27001 certification

• ISO 27018-related assessment

• Evidence of implementation

• Cloud PII control assessment

• Customer assurance

• Integration of relevant ISO 27018 guidance into an ISO 27001-based ISMS

Getting this distinction right at the beginning can prevent an organization from selecting an assessment route that does not match its actual requirement.

How to Start an ISO 27018 Assessment

Start with the service, not the checklist.

Define the cloud service being assessed and identify the PII that enters or passes through it. Then establish which systems, people, suppliers and customer relationships are involved.

A practical initial review can ask:

What PII is processed?

Who owns or controls it?

Who processes it?

Where does the information go?

Who can access it?

Which third parties are involved?

How long is it retained?

What happens when processing ends?

What evidence demonstrates that controls are operating?

The answers provide a much more useful starting point than copying a generic ISO checklist.

ISO 27018 Implementation Steps

Define the Cloud Service Scope

Identify the public-cloud services, applications, infrastructure and supporting processes covered by the assessment.

Map PII Processing

Document the categories of PII involved and how information moves through the service.

Establish Responsibilities

Clarify responsibilities between the customer, cloud provider, subcontractors and other service providers.

Review Access

Examine privileged access, authentication, authorization and administrative activity.

Review Suppliers

Identify cloud suppliers, subprocessors and technology partners that may process or access PII.

Review Retention and Deletion

Establish how PII is retained, returned or deleted when the applicable processing purpose ends.

Review Incident Handling

Confirm that relevant security and privacy incidents can be identified, escalated, investigated and documented.

Maintain Evidence

Policies are only one part of the assessment. The organization should maintain evidence showing that controls are actually operating.

ISO 27018 Documentation for Indian Organizations

The evidence required depends on the scope, but may include:

• Cloud-service scope

• PII-processing information

• Data-flow diagrams

• Customer agreements

• Supplier agreements

• Access-control records

• Privileged-access records

• Incident records

• Retention requirements

• Deletion records

• Risk assessments

• Training records

• Internal audit evidence

• Corrective-action records

The useful test is consistency.

If the customer contract says one thing, the documented procedure says another and the technical system operates differently, an assessment is likely to expose that gap.

ISO 27018 Cost in India

There is no standard fixed price for ISO 27018-related assessment or implementation support in India.

The effort depends on factors such as:

• Organization size

• Cloud-service scope

• Number of applications

• PII-processing complexity

• Existing ISO 27001 arrangements

• Supplier relationships

• Locations

• Customer requirements

• Existing controls

• Assessment objectives

A small SaaS provider in Bengaluru and a large managed-cloud provider serving multiple enterprise customers are unlikely to have the same requirements.

A meaningful commercial proposal should therefore follow a scope discussion.

ISO 27018 Timeline in India

There is no universal implementation period.

An organization with a mature ISO 27001-based ISMS may already have many of the underlying security processes required to address cloud PII controls.

A business starting with limited documentation may need additional work around:

• Access management

• Supplier management

• PII mapping

• Retention and deletion

• Incident management

• Customer commitments

• Evidence collection

The appropriate timeline should be determined after a readiness review.

ISO 27018 in Bengaluru

Where public-cloud services process PII, companies in Chandigarh, Mohali and Panchkula can evaluate the relevance of ISO 27018.

ISO 27018 Across Other Indian Locations

SCS can receive enquiries from organizations across major Indian technology and industrial centres, including:

Maharashtra: Mumbai, Pune, Navi Mumbai, Thane, Nashik, Nagpur, Kolhapur and Chhatrapati Sambhajinagar.

Karnataka: Bengaluru, Mysuru, Mangaluru, Hubballi, Belagavi and Tumakuru.

Tamil Nadu: Chennai, Coimbatore, Hosur, Madurai, Salem, Tiruppur, Tiruchirappalli, Erode and Vellore.

Telangana: Hyderabad and other technology centres.

Kerala: Kochi, Thiruvananthapuram, Kozhikode, Thrissur, Kollam and Kannur.

Gujarat: Ahmedabad, Vadodara, Surat, Gandhinagar, Rajkot, Bharuch, Ankleshwar and Vapi.

Andhra Pradesh: Visakhapatnam, Vijayawada, Tirupati, Guntur, Nellore and Kakinada.

West Bengal: Kolkata and surrounding technology and business centres.

Odisha: Bhubaneswar and other digital-business locations.

Madhya Pradesh: Indore and Bhopal.

Rajasthan: Jaipur, Jodhpur and Udaipur.

Uttar Pradesh: Lucknow, Kanpur, Noida and Greater Noida.

The location does not determine whether ISO 27018 applies. The deciding factors are the cloud service, processing role, PII environment, contractual requirements and defined scope.

Benefits of ISO 27018 for Indian Cloud Businesses

For an Indian cloud provider, the value of ISO 27018 is best considered in practical terms.

It can help provide a structured approach to:

• Public-cloud PII protection

• Customer assurance

• Cloud privacy controls

• Processing responsibilities

• Third-party oversight

• Access management

• PII lifecycle management

• Contractual requirements

• Auditability and evidence

ISO identifies benefits including clearer roles between cloud providers and customers, support for contractual and regulatory obligations, transparency, auditability and accountability in PII processing.

For Indian businesses competing for enterprise customers, these areas can matter during vendor assessments and procurement discussions.

Why Indian Cloud Providers Should Review ISO 27018 Now

The business case is becoming more specific than simply saying that “cloud security is important.”

An Indian provider may face a customer questionnaire asking where PII is stored, which subprocessors are involved, how access is controlled, what happens after contract termination and what independent evidence exists.

At the same time, the provider may need to consider Indian privacy legislation, CERT-In requirements and customer-specific contractual obligations.

ISO 27018 provides a useful reference point for the public-cloud PII-processing part of that conversation.

It does not answer every legal or cybersecurity question. That is precisely why it works best as part of a broader information-security and privacy programme.
