ISO 27001 for SaaS Companies: Scope, Controls, and Certification
ISO 27001 for SaaS gives enterprise buyers one accredited answer to the security questions that slow deals down. Accredify Global certifies SaaS and cloud software providers to ISO/IEC 27001:2022 with senior-led audits and a fixed fee. We scope the product your customers actually buy, so the certificate holds up in procurement. Audit days scale with headcount, so startups pay for the scope they have, and cloud-first teams can be audited largely or fully remotely.
What ISO 27001 Means for a SaaS Company
ISO 27001 for SaaS is certification of the information security management system behind your product. An accredited auditor checks that you assess risks to customer data, choose controls for them, and run those controls every day. That covers code, cloud, people, and suppliers. A passed audit leads to a certificate valid for three years, with yearly surveillance audits.
For a software company, the certificate is mainly a sales tool. Procurement teams at banks, hospitals, and large enterprises send long security questionnaires. An accredited ISO 27001 certificate, with the right scope, answers many of those questions in one document and moves the deal to legal review sooner.
Accredify Global audits how your team actually ships and runs software. We look at pull requests, deployment logs, access reviews, and incident tickets, not just policy documents.
ISO 27001 for SaaS in 2026: One Edition, New Privacy Options, Stricter Buyers
ISO/IEC 27001:2022 is now the only edition. The transition from the 2013 version ended on 31 October 2025. Every valid certificate now refers to the 2022 edition and its 93 Annex A controls. A 2024 amendment added climate change to the context clauses.
Cloud privacy standards were refreshed. ISO/IEC 27018 was revised in 2025 for public cloud providers that process personal data. ISO/IEC 27701:2025 became a standalone privacy standard that can be certified without ISO 27001 underneath it.
Buyers pass their own rules down to you. European customers covered by NIS2 or DORA now check their suppliers more closely. Expect contract clauses on incident notice, audit rights, and exit plans, and expect them to ask what your certificate covers.

Defining the Scope of ISO 27001 for SaaS
Customers read the scope statement on your certificate. If production is missing, the certificate rarely satisfies them.
| Part of the business | Usually in scope? | What the auditor looks for |
|---|---|---|
| The application customers use | Yes | Access control, tenant separation, and secure releases |
| Production cloud accounts | Yes | Configuration baselines, logging, and backups |
| CI/CD pipeline and repositories | Yes | Code review, secrets handling, and deployment approvals |
| Customer support | Usually | Who can see customer data, and why |
| Cloud provider infrastructure | No, it is a supplier | How you assess and monitor the provider |
| Internal tools and offices | Often | Laptops, identity, and onboarding and offboarding |
The shared responsibility model is where SaaS scopes go wrong most often. Your cloud provider's certificate covers its data centers and hardware. It does not cover your identity settings, storage permissions, or code. The audit checks that you know where the line sits, and that your side of it is controlled.
The Annex A Controls That Matter Most for SaaS
All 93 controls are considered, but these are where SaaS audits spend most of their time.
| Control area | Annex A reference | Typical SaaS evidence |
|---|---|---|
| Cloud services | 5.23 | Provider due diligence and exit planning |
| Suppliers | 5.19 to 5.22 | A register of subprocessors and contract terms |
| Secure development | 8.25 to 8.29 | Code review, testing, and secure coding rules |
| Configuration | 8.9 | Infrastructure as code and drift detection |
| Logging and monitoring | 8.15, 8.16 | Centralized logs and alert response |
| Data deletion and masking | 8.10, 8.11 | Retention rules and test data handling |
| Threat intelligence | 5.7 | Sources reviewed and acted on |
ISO 27001 vs SOC 2 and Other SaaS Assurance
Most SaaS companies need more than one. Choose by who your buyers are, and reuse one control set.
| Assurance | What it is | Who usually asks |
|---|---|---|
| ISO 27001 | Accredited certificate for your security system | Global enterprises and public sector buyers |
| SOC 2 | An attestation report issued by a licensed CPA firm | US enterprise customers |
| ISO 27017 / ISO 27018 | Cloud and cloud privacy controls added to your ISO 27001 scope | Customers moving regulated data to the cloud |
| ISO 27701 | Certified privacy management | Buyers with GDPR or privacy duties |
| ISO 42001 | Certified AI management | Buyers assessing AI features |
ISO 27001, ISO 27701, and ISO 42001 are within our UAF accreditation scope and can be audited together.
Our guide to ISO 27001 vs SOC 2 covers the choice in detail. If you sell to healthcare, HIPAA evidence matters too, and payment features bring PCI DSS into view. One well-run ISMS supplies evidence for all of them.
How ISO 27001 Certification Works for SaaS Teams
The steps are the same for every company. For SaaS, most evidence lives in tools you already use. Our certification process guide has more detail, and how to get ISO 27001 certified covers preparation.

Small, fast-moving teams tend to trip over the same few things.
| Finding | Why it happens |
|---|---|
| Former staff still have access | Offboarding misses a SaaS tool or cloud account |
| Risk assessment not updated | New features ship without a risk review |
| Subprocessor list out of date | Engineers add tools without telling security |
| Backups never restored | Backups run, but recovery is never tested |
| Internal audit too shallow | Done as a checklist just before Stage 2 |
Compliance automation platforms help with evidence collection and control tracking. They do not replace the audit. An accredited certification body must still test that controls work and decide on certification. The best results come when the platform's evidence matches what really happens in your tools.

FAQ: ISO 27001 for SaaS Companies
Answers on scope, SOC 2, cloud providers, AI, cost, and timeline.
Why do SaaS companies get ISO 27001 certified?
Enterprise buyers, especially outside the US, ask for it during procurement. An accredited certificate answers many security questionnaire items at once and shortens vendor reviews.
Is ISO 27001 or SOC 2 better for a SaaS company?
It depends on your buyers. US customers often ask for SOC 2, while European, Middle Eastern and Asian customers usually ask for ISO 27001. Many SaaS companies end up with both and reuse the same controls.
What should the certificate scope include?
The product your customers buy: the application, production environment, deployment pipeline, the people who run it, and support. Customers check the scope statement, so a narrow scope that leaves out production rarely satisfies them.
Does our cloud provider's certificate cover us?
No. AWS, Azure and Google Cloud certify their infrastructure. You are responsible for everything you build and run on it, including access, configuration, code and data.
Which ISO 27001 controls matter most for SaaS?
Cloud service security, secure development, configuration management, logging and monitoring, supplier management, access control, and data deletion. Annex A of ISO 27001:2022 covers all of these.
What are ISO 27017 and ISO 27018?
They are codes of practice that add cloud-specific security controls and controls for protecting personal data in public clouds. Many SaaS providers include them in their Statement of Applicability so the ISO 27001 audit covers them.
Do we need ISO 27701 too?
If you process customer personal data, it helps. ISO/IEC 27701:2025 can now be certified on its own and adds privacy roles and processes that support GDPR and US state privacy laws.
Our product uses AI. Do we need ISO 42001?
If AI features matter to your buyers, ISO 42001 certifies how you govern them. It sits on the same management system structure as ISO 27001, so the two can be audited together.
Can a startup with 20 people get ISO 27001?
Yes. The standard scales to small teams. Audit days follow headcount and complexity, so a small, cloud-native company usually needs fewer days than a larger firm.
Do remote teams affect the audit?
No. Fully remote SaaS companies certify regularly. When no physical sites are in scope, the audit can run largely or fully remotely, and the auditor reviews how you secure laptops, home working and cloud access.
How long does ISO 27001 take for a SaaS company?
Most SaaS companies with a working system certify in 6 to 12 weeks from Stage 1 to the certificate. Before Stage 2, you need at least one internal audit and management review.
How much does ISO 27001 cost for a SaaS company?
The fee follows the audit man-days your scope needs, set mainly by headcount and complexity. A free scoping review gives you one fixed-fee proposal.
Is Accredify Global accredited for ISO 27001?
Yes. ISO 27001 is within our UAF accreditation scope, which you can check in the UAF directory.
Can you help us write our ISMS policies?
No. As a certification body we must stay impartial, so we audit and certify but do not write your system. Your team, or a consultant you choose, builds it.
Do compliance automation tools replace the audit?
No. Tools help collect evidence and track controls, but an accredited certification body must still audit your system and decide on certification.
