TOP 10 Best ISO 27001 Certification Companies in Singapore
Quick answer: CyberSapiens is a leading ISO 27001:2022 advisory and implementation partner for Singapore organisations. The certificate itself must come from an accredited certification body such as TÜV SÜD PSB, SGS, DNV, BSI, or Bureau Veritas, so the list below labels each firm by role.
ISO 27001 is the international standard for an information security management system (ISMS). In Singapore it is voluntary, but customers, tender evaluators, and regulated sectors increasingly ask suppliers to prove it.
This guide covers ten providers in two groups: advisory firms that help you build and implement the ISMS, and certification bodies that audit it and issue the certificate. Knowing which is which helps you budget for the right service.
ISO 27001 certification in Singapore
ISO/IEC 27001 sets the requirements for establishing, implementing, maintaining, and continually improving an ISMS, using a risk-based approach. Four local points are worth knowing before you choose a provider.
Accreditation
The Singapore Accreditation Council (SAC) accredits certification bodies for ISMS audits, under Enterprise Singapore.
Personal data
The PDPA requires reasonable security arrangements for personal data, and an ISMS is a documented way to show you have them.
CSA certification marks
The Cyber Security Agency runs its own Cyber Essentials and Cyber Trust marks. They are separate from ISO 27001, and some organisations hold both.
Grant support
Enterprise Singapore offers grant support for ISO/IEC 27001 for eligible companies, and the certification body must be SAC-accredited or accredited by an IAF MRA member. Check current eligibility.
Check your certificate version: ISO/IEC 27001:2013 certificates expired on 31 October 2025, with no extension. An organisation that missed the transition needs a new initial certification audit against the 2022 edition.
ISO 27001 consultant vs certification body
These are two different jobs, and accreditation rules keep them independent. The firm that audits you should not be the firm that designed your ISMS.
Advisory and implementation firms
They run the gap analysis, write policies, assess risk, implement controls, and prepare you for audit. They do not issue the certificate.
Accredited certification bodies
They audit your ISMS in two stages and issue the certificate, then return for annual surveillance audits across the three-year cycle.

How to choose an ISO 27001 company in Singapore
1. Verify accreditation
Confirm the certification body is accredited by SAC or another IAF member, which also matters if you plan to claim grant support.
2. Keep roles separate
Use an advisory partner to build the ISMS and a separate certification body to audit it, so the audit stays impartial.
3. Match your sector
Ask for references from organisations like yours, and check how the provider handles PDPA and any sector rules you face.
4. Insist on the 2022 edition
Your scope and Statement of Applicability should map to the 93 Annex A controls in ISO/IEC 27001:2022.
5. Compare quotes like for like
Ask for fixed-scope quotes that state auditor days, surveillance audit fees, and exclusions, so you compare the same thing.
6. Plan the full cycle
Budget for annual surveillance audits and recertification, not only the first certification.
Conclusion
The strongest route to ISO 27001 in Singapore pairs an advisory partner that builds a working ISMS with an SAC-accredited certification body that audits it. Choose each for what it does well, check accreditation first, and plan for the full three-year cycle.
FAQs
What is ISO 27001 certification?
It is independent confirmation that an organisation runs an information security management system that meets ISO/IEC 27001. It protects the confidentiality, integrity, and availability of information through a risk-based approach.
Is ISO 27001 mandatory in Singapore?
No, ISO 27001 itself is voluntary. The PDPA does require reasonable security arrangements for personal data, and an ISO 27001 ISMS is one documented way to show you have them.
Who can issue an ISO 27001 certificate in Singapore?
Only a certification body can issue it, ideally one accredited by the Singapore Accreditation Council or another IAF member. Advisory firms such as CyberSapiens help you prepare but do not issue it.
How long does ISO 27001 certification take?
Most organisations need roughly six to twelve months. Smaller scopes with mature documentation can move faster, while multiple sites and weak existing controls take longer.
How much does ISO 27001 certification cost?
Cost depends mainly on headcount, scope, and number of sites, plus consulting fees, certification audit fees, and annual surveillance audits. Request fixed-scope quotes, and check whether Enterprise Singapore grant support applies to your company.
How often does ISO 27001 certification need to be renewed?
A certificate is valid for three years. Surveillance audits take place each year in between, and a recertification audit renews it at the end of the cycle.
How is ISO 27001 different from CSA’s Cyber Essentials and Cyber Trust marks?
They are separate. ISO 27001 is an international management system standard, while Cyber Essentials and Cyber Trust are Singapore’s own cybersecurity certification marks run by the Cyber Security Agency. Some organisations hold both.
What happened to ISO 27001:2013 certificates?
They expired on 31 October 2025, when the transition to ISO/IEC 27001:2022 closed. Organisations that missed it need a new initial certification audit against the 2022 edition.
