TOP 10 Best ISO 27001 Certification Companies in Australia(2026)
The best ISO 27001 certification company in Australia depends on the job. A consultant (such as CyberSapiens, CyberPulse or FOIT Group) builds your ISMS and gets you audit-ready. An accredited certification body (such as BSI, Intertek SAI Global, SGS, Bureau Veritas, TQCSI or LRQA) runs the Stage 1 and Stage 2 audits and issues the certificate. Most Australian businesses need one of each.
Disclosure: this list is written by CyberSapiens, an ISO 27001 consultancy, and we include ourselves at number 1. Every other company’s details were taken from its own website and checked in October 2026. We were not paid to include anyone. If you spot an error, tell us and we will fix it.
Searching for “ISO 27001 certification companies” in Australia gives you a confusing mix of consultants, global audit firms and software tools. They do very different jobs. This guide sorts the top 10 ISO 27001 certification companies in Australia for 2026 into two clear groups, explains what each one does, and shows you how to check that a certificate is genuine before you sign anything.

The top 10 ISO 27001 certification companies in Australia (2026)
CyberSapiens – best end-to-end ISO 27001 consultant for SMEs and SaaS
CyberSapiens takes you from first gap analysis to certificate: scoping, risk assessment, Statement of Applicability, policies, Annex A controls, internal audit and support on the day of your Stage 1 and Stage 2 audits. We then work alongside our accredited certification partners, such as Gabriel Registrar, so the audit stays independent. CyberSapiens holds its own ISO 27001:2022 certification, so we follow the same process we sell.
- Fixed-price engagements – see our ISO 27001 certification cost guide
- Combined programmes with SOC 2, Essential Eight and penetration testing
- Support for surveillance audits in years 2 and 3
Best for: Australian SMEs, startups and SaaS companies that want one team to do the work. See our ISO 27001 certification services in Australia →
BSI Australia – certification body with a global brand
BSI is the UK’s national standards body and one of the best-known names in ISO certification worldwide. It entered the Australian certification market in 2006 by acquiring Benchmark Certification. BSI audits and certifies organisations against ISO/IEC 27001, and its certificates can be checked in BSI’s online certificate directory.
Best for: organisations selling overseas that want a certificate brand buyers recognise. You will still need to build your ISMS first, either in-house or with a consultant.
Intertek SAI Global – long-standing Australian certifier
Intertek SAI Global audits and certifies Australian organisations against ISO 27001 and many other standards. Its public certification register lets anyone search for certified organisations and check the scope of their certificate. It also offers training and a marketplace for finding consultants.
Best for: businesses that already hold ISO 9001 or ISO 14001 with SAI Global and want one auditor for several standards.
SGS Australia – accredited for ISO 27001 audits in Australia
SGS is a global testing, inspection and certification group. In November 2024 SGS announced it had been accredited to perform ISO 27001 audits in Australia. SGS Australia also runs ISO/IEC 27001 training, including internal auditor and lead auditor courses.
Best for: organisations that want certification and also need to train staff as internal auditors.

ISO 27001 consultant vs certification body: what’s the difference?
ISO 27001 consultant
- Runs the gap analysis and risk assessment
- Writes policies, procedures and the Statement of Applicability
- Helps put Annex A controls in place
- Runs your internal audit and management review
- Prepares your team for the external audit
Certification body (auditor)
- Runs the Stage 1 (documents) and Stage 2 (evidence) audits
- Issues the ISO 27001 certificate if you pass
- Runs surveillance audits in years 2 and 3
- Must be accredited by an IAF-recognised accreditation body
- Cannot consult on the same ISMS it certifies
That last point matters. Under the international rules for certification bodies (ISO/IEC 17021-1), a certifier must stay impartial, so it cannot design your ISMS and then audit it. That is why most Australian businesses use one consultant and one certification body. If a single company offers to “consult and certify” you, ask exactly which accredited body will issue the certificate.
How to choose the right ISO 27001 certification company
- Decide what you need. No security team? Start with a consultant. Already have a working ISMS? You may only need a certification body.
- Check the accreditation. Ask which accreditation body covers the certifier’s ISO 27001 work, and make sure it is a member of the International Accreditation Forum (IAF) so your certificate is recognised by customers in Australia and overseas.
- Make sure it’s ISO 27001:2022. The transition period for the old 2013 version ended on 31 October 2025, so new certificates should show ISO/IEC 27001:2022.
- Ask about Australian rules. A good partner maps your ISMS to the Privacy Act, Essential Eight and, for financial services, APRA CPS 234.
- Get a fixed scope and price. Ask what is included: number of sites, people, internal audit, audit-day support, and years 2–3.
- Ask for proof. Request the consultant’s own certificate or case studies, and the certifier’s accreditation number.
How to check an ISO 27001 certificate is real
Before you trust a supplier’s certificate – or choose a company to certify you – do these three checks. They take about five minutes.
- Search the certifier’s register. BSI, Intertek SAI Global and most large certification bodies have an online directory where you can enter the certificate number or company name.
- Search IAF CertSearch. The International Accreditation Forum’s database (iafcertsearch.org) lists certificates issued under accredited schemes.
- Read the scope. A certificate only covers the sites, services and systems written on it. Check the scope matches what you are buying.

How much does ISO 27001 certification cost in Australia?
Cost has two parts: the consultant (if you use one) and the certification body’s audit fees for Stage 1, Stage 2 and the two surveillance years. Company size, number of sites and how much security you already have make the biggest difference. For first-year totals by company size, see our ISO 27001 certification cost guide for Australia. For timelines, read how long ISO 27001 certification takes.
Frequently asked questions
Which is the best ISO 27001 certification company in Australia?
There is no single best company because consultants and certification bodies do different jobs. For an end-to-end consultant, CyberSapiens, CyberPulse and FOIT Group are strong options. For the certificate itself, choose an accredited certification body such as BSI, Intertek SAI Global, SGS, Bureau Veritas, TQCSI or LRQA.
What is the difference between an ISO 27001 consultant and a certification body?
A consultant helps you build and run your information security management system and prepares you for the audit. A certification body is an independent, accredited auditor that runs the Stage 1 and Stage 2 audits and issues the certificate. The same company cannot do both for your ISMS.
Which accreditation should an ISO 27001 certificate have?
Choose a certificate issued by a certification body that is accredited by a member of the International Accreditation Forum (IAF). IAF recognition means the certificate is accepted internationally, and you can look it up in IAF CertSearch.
How much does ISO 27001 certification cost in Australia?
It depends on company size, scope and how ready you are. You pay a consultant for implementation (if you use one) and a certification body for the audits over a three-year cycle. Our ISO 27001 certification cost guide gives first-year totals by company size in AUD.
How long does ISO 27001 certification take?
For most small and mid-sized Australian businesses it takes about four to six months from gap analysis to certificate. Larger organisations, or those starting with few security controls, can take longer.
Can the same company consult and certify us?
No. Accredited certification bodies must stay impartial, so they cannot design your ISMS and then certify it. Use a consultant to prepare and a separate accredited certification body for the audit.
How do I check if an ISO 27001 certificate is valid?
Search the certificate number in the issuing certification body’s online register or in IAF CertSearch, check that it shows ISO/IEC 27001:2022, and read the scope to make sure it covers the services you are buying.
Is an ISO 27001:2013 certificate still valid?
No. The transition period for ISO/IEC 27001:2013 ended on 31 October 2025. Current certificates should be issued against ISO/IEC 27001:2022.
