ISO 27017 Cloud Security Controls.

Prove Your Cloud Security, Not Just Your Paperwork

ISO 27017 extends ISO 27001 with security controls specific to cloud services — clarifying exactly where your responsibility ends and your cloud provider’s begins. It’s increasingly the standard enterprise clients expect before they’ll trust you with their data in the cloud.

As an ISO 27017 consultant working across the UK, Ireland and the Isle of Man, Compliance Managers helps cloud service providers and cloud-dependent businesses build the specific controls this standard requires — without duplicating work you’ve already done for ISO 27001.

Why ISO 27017 Matters.

ISO 27017 is the international code of practice for information security controls in cloud services. It applies to both cloud providers and organisations that use cloud services, clarifying shared responsibilities and closing gaps that ISO 27001 alone doesn’t fully address.

BUILD CLIENT TRUST IN YOUR PLATFORM

Give enterprise clients independently verified proof your cloud environment is properly secured.

WIN ENTERPRISE & PUBLIC SECTOR WORK

Increasingly requested in vendor security questionnaires and cloud procurement tenders.

CLARIFY SHARED RESPONSIBILITIES

Formal documentation of exactly what you’re responsible for versus your cloud provider — no ambiguity in an incident.

STRENGTHEN YOUR ISO 27001 SYSTEM

Builds directly on an existing ISMS rather than requiring you to start again from scratch.

Working With an ISO 27017 Consultant UK Businesses Trust

We support rollout of the new controls and train your team on the cloud-specific procedures.

Frequently Asked Questions

Why should my business get ISO 27017 certified?

ISO 27017 gives clients and partners independently verified proof that your cloud environment is properly secured, with clear controls specific to cloud services that ISO 27001 alone doesn’t fully cover. It’s increasingly requested in vendor security questionnaires and cloud procurement tenders, so certification can directly unblock enterprise sales.

Do we need ISO 27001 first before we can get ISO 27017?

ISO 27017 is designed to extend an existing ISO 27001 Information Security Management System with cloud-specific controls, so in practice you need an ISO 27001-aligned ISMS in place first. If you don’t have one yet, we can scope both together so you’re not paying to build the same foundation twice.

Is ISO 27017 only for cloud providers, or also cloud customers?

Both. The standard sets out controls and responsibilities for cloud service providers and for organisations that use cloud services, since security in the cloud is a shared responsibility. Which controls apply to you depends on which side of that relationship you’re on for a given service.

What's the difference between ISO 27017 and ISO 27018?

ISO 27017 covers general information security controls for cloud services. ISO 27018 is narrower and focuses specifically on protecting personally identifiable information (PII) in public cloud environments. Many cloud providers pursue both together since they address related but distinct risks.

What happens during an ISO 27017 audit?

An accredited certification body auditor reviews your cloud-specific controls, shared responsibility documentation, and evidence that they’re followed in practice — alongside your existing ISO 27001 controls if you’re certifying to both. We run an internal readiness review beforehand so nothing is a surprise on the day.
