ISO 27017 Certification – Information Security Controls for Cloud Services

What is ISO 27017 Certification?

ISO 27017 Certification demonstrates that an organization has implemented internationally recognized information security controls for cloud services. It is based on ISO/IEC 27017, developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

The standard provides additional guidance for relevant controls specified in ISO/IEC 27002:2022, along with additional controls and guidance that specifically relate to cloud services. It provides controls and guidance for both cloud service customers (CSCs) and cloud service providers (CSPs).

ISO 27017 is not a standalone management system standard. It supplements ISO/IEC 27001 certification. Organizations achieve ISO 27017 Certification by including its cloud security controls within the scope of their ISO 27001 Information Security Management System, which is then audited by an accredited certification body.

What's New in ISO/IEC 27017:2026?

ISO 27017 Certification is now based on the latest edition of the standard:

• Current Edition: ISO/IEC 27017:2026 is the current edition and replaces ISO/IEC 27017:2015.
• Updated Title: The standard is now titled "Information security, cybersecurity and privacy protection — Information security controls based on ISO/IEC 27002 for cloud services."
• Alignment with ISO 27002:2022: The new edition is explicitly based on ISO/IEC 27002:2022, whereas the 2015 edition was built on the previous ISO/IEC 27002 structure.
• Reorganized Cloud Controls: The 2026 edition reorganizes those topics around the ISO/IEC 27002:2022 structure rather than preserving the old seven-control set.

This alignment makes ISO 27017 Certification more consistent with ISO 27001:2022, simplifying integration and audits. Organizations already working with the 2015 edition should review the new edition and update their Statement of Applicability and cloud controls accordingly.

Why is ISO 27017 Certification Important?

Cloud adoption has transformed how businesses operate, but it has also created new security challenges. Data and applications now run on shared infrastructure, managed partly by providers and partly by customers. Without clear responsibilities and consistent safeguards, gaps can develop between the expectations of cloud customers and the practices of cloud providers.

ISO 27017 Certification closes these gaps. It shows that an organization understands cloud-specific risks, has defined who is responsible for which security controls, and has implemented safeguards suited to cloud environments. For cloud providers, it is a powerful trust signal when winning enterprise clients. For cloud customers, it demonstrates responsible and secure use of cloud services.

Who Can Get ISO 27017 Certification?

ISO 27017 Certification applies to two types of organizations, and many organizations fall into both categories:

• Cloud Service Providers (CSPs): Organizations that offer cloud services, such as IaaS, PaaS, and SaaS providers, data centers, hosting companies, and managed service providers.
• Cloud Service Customers (CSCs): Organizations that use cloud services to store data or run business applications.

ISO/IEC 27017 applies to all cloud deployment models, including public, private and hybrid cloud environments. For private cloud, adjustments can be necessary to adapt to the relationships and abilities of an organization's internal departments.

Key Focus Areas of ISO 27017 Certification

ISO 27017 Certification covers cloud-specific security topics such as:

• Shared Roles and Responsibilities: Clearly allocating security responsibilities between provider and customer.
• Segregation in Virtual Environments: Isolating each customer's data and resources.
• Virtual Machine and Configuration Security: Hardening virtual machines and cloud configurations.
• Administrator Operations: Controlling and documenting privileged cloud operations.
• Monitoring of Cloud Services: Enabling customers to monitor relevant aspects of the services they use.
• Removal of Customer Assets: Returning or securely removing customer assets when services end.
• Access Control and Cryptography: Managing cloud access and encryption responsibilities.
• Logging and Incident Management: Coordinating security events and incidents between provider and customer.
• Supplier Relationships: Managing security across the cloud supply chain.

For a detailed explanation of each control area, see our ISO 27017 Cloud Security: Controls, Benefits & Certification guide.

Achieve ISO 27017 Certification: A Strategic 10-Step Approach

1. Initial Consultation and Cloud Assessment

We begin by understanding your cloud services, deployment models, and whether your organization acts as a cloud service provider, customer, or both, to create an effective ISO 27017 Certification roadmap.

2. Define Certification Scope

The ISMS scope is defined to include cloud services, infrastructure, platforms, and related processes.

3. Gap Analysis

Existing cloud security practices are assessed against ISO 27001 requirements and ISO/IEC 27017:2026 guidance to identify gaps.

4. Cloud Risk Assessment

Cloud-specific risks, such as multi-tenancy, misconfiguration, data leakage, privileged access misuse, and supplier dependencies, are identified and evaluated.

5. Shared Responsibility Mapping

Security responsibilities between your organization and its cloud providers or customers are defined, documented, and communicated.

6. Documentation Development

The Statement of Applicability, cloud security policies, procedures, service agreements, and customer-facing documentation are developed or updated.

7. Cloud Security Control Implementation

Controls for segregation, configuration hardening, administrator security, monitoring, logging, and asset removal are implemented across cloud environments.

8. Internal Audit

Internal audits are conducted to evaluate compliance with ISO 27001 and ISO 27017 controls and identify corrective actions.

9. Management Review

Top management reviews ISMS and cloud security performance, risks, incidents, and improvement opportunities.

10. Certification Audit and Achieving ISO 27017 Certification

An accredited certification body conducts Stage 1 and Stage 2 audits covering ISO 27001 and ISO 27017 controls. ISO 27017 Audit Services can help organizations prepare for the audit. On successful completion, your organization receives certification demonstrating alignment with ISO 27017.

With this structured 10-step approach, cloud providers and customers can achieve ISO 27017 Certification efficiently while strengthening security across their cloud environments.

ISO 27017 Certification with ISO 27001, ISO 27018, and ISO 27701

ISO 27017 Certification works best as part of an integrated approach:

• ISO 27001: Provides the Information Security Management System foundation within which ISO 27017 controls are certified.
• ISO 27018: Adds protection for personal data in public cloud services. ISO/IEC 27018:2025 applies specifically to the protection of personally identifiable information in public cloud services when the CSP acts as a PII processor.
• ISO 27701: Provides a full Privacy Information Management System for organizations managing personal data across their operations.

Many cloud providers implement ISO 27001, ISO 27017, and ISO 27018 together, and add ISO 27701 for complete security and privacy assurance, with shared policies, risk processes, and combined audits.

Benefits of ISO 27017 Certification

• Stronger Cloud Security: Addresses risks unique to cloud environments.
• Clear Shared Responsibilities: Removes confusion over who secures what.
• Enhanced Client Trust: Demonstrates internationally recognized cloud security practices.
• Competitive Advantage: Helps win enterprise clients and tenders requiring cloud security assurance.
• Faster Vendor Approvals: Simplifies security questionnaires and due diligence.
• Reduced Risk of Breaches: Strengthens segregation, configuration, and access controls.
• Better Supplier Oversight: Improves management of cloud sub-providers.
• Improved Transparency: Gives customers clarity on security practices.
• Integrated Compliance: Works seamlessly with ISO 27001, ISO 27018, and ISO 27701.
