Cloud security, proven. ISO 27017 extends ISO 27001 with controls written specifically for the cloud — addressing the shared-responsibility, multi-tenancy, and virtualisation risks that general standards don't fully cover.
ISO/IEC 27017:2015 is a code of practice for cloud security, building on the ISO 27002 controls with cloud-specific guidance for both providers and customers.
It clarifies the division of security responsibility between cloud provider and customer, and adds controls for issues unique to cloud — virtual machine hardening, administrative-operation segregation, and the return or removal of assets when a service ends.
It is implemented as an extension to an ISO 27001 ISMS and certified alongside it, making it a natural add-on for cloud-native businesses.
Demonstrates cloud-specific security maturity to enterprise buyers.
Companies whose entire delivery runs on public-cloud infrastructure.
Organisations needing assurance over the cloud services they depend on.
Delivered through our specialist network, typically alongside ISO 27001. Because it extends your existing ISMS, the incremental work is focused on the cloud-specific controls rather than a full separate programme.
We define the boundary of your programme — systems, locations, and teams in scope — and agree the timeline and responsibilities up front, so there are no surprises later.
A structured assessment of your current posture against every requirement, producing a prioritised remediation plan with realistic effort estimates.
We write the policies, procedures, and controls, and work alongside your engineering team on a weekly cadence to implement them — not a stack of templates left for you to figure out.
The management system runs and generates evidence. We drive the internal audit and management review so the programme is demonstrably working before any external scrutiny.
We prepare the evidence package and sit alongside you through assessment, answering the assessor's questions directly rather than leaving you to defend the work alone.
If you sell cloud services to enterprise or regulated customers, they will ask who is responsible for what once their data sits in your platform. ISO 27017 gives you a recognised, auditable answer, which is why it is increasingly requested in procurement for SaaS, hosting and infrastructure providers.
Provider or customer? The standard provides guidance for both sides. As a cloud provider you show how you secure the service and where your responsibility ends. As a cloud customer you show how you manage the services you consume. We help you document the shared-responsibility split clearly, because that is where most customer questions come from.
Built on ISO 27001. ISO 27017 is implemented as an extension of an ISO 27001 ISMS and certified alongside it, so the two share one audit cycle. If you do not have ISO 27001 yet, we plan both together. See our ISO 27001 page, and our SOC 2 page if US customers are also asking.
Remote-first delivery. ISONEX works remotely with clients across the GCC, UK, EU and US. We map the cloud-specific controls, build the evidence and prepare you for the audit, with calls scheduled around your working hours. Book a free advisory session.
No — it's an extension to ISO 27001 and is certified together with it. If you already hold ISO 27001, adding ISO 27017 is a focused piece of additional work rather than a fresh engagement.
For a cloud-native business, often yes. It signals to enterprise buyers that you've addressed the security risks specific to cloud, which a general ISO 27001 certificate doesn't explicitly evidence.
Yes. ISONEX is a remote-first consultancy and we deliver cloud security programmes for clients in the UK, the US, Europe and the GCC. Everything is done online, scheduled around your working hours.
It is implemented as an extension to an ISO 27001 ISMS and certified alongside it. Your certification body confirms how it appears on your certificate and scope.
In practice yes, or at the same time, because ISO 27017 builds on an existing ISMS. We usually plan both together.
No. It gives guidance to both cloud service providers and cloud service customers, though providers are the ones most often asked for it.
