What is an ISO 27001 certification body?

An ISO 27001 certification body is an independent, third-party organisation accredited to assess your Information Security Management System (ISMS) and issue ISO 27001 certification once you’ve passed your external certification audit.

ISO 27001 certification companies independently verify that your ISMS meets the requirements of the ISO/IEC 27001 internationally recognised standard. This covers everything from information security controls and risk assessment to protecting data and preventing data breaches. These bodies providing audit and certification services issue a certificate that carries formal, globally recognised authority once verification is complete.

In Australia, that authority comes from accreditation. Without it, a certificate may look the part, but government procurement bodies, enterprise clients, and financial institutions conducting vendor risk assessments won’t accept it.

Why accreditation is your starting point

Before you compare services, pricing, or auditor experience, check one thing: is the certification body accredited?

In Australia, JAS-ANZ is the government-appointed body responsible for accrediting ISO certification bodies and overseeing the accreditation process. JAS-ANZ assesses every accredited body for competence, impartiality, and audit quality. Through the International Accreditation Forum (IAF), JAS-ANZ accredited certificates align with a globally recognised standard and are accepted internationally, not just locally. Use the IAF CertSearch tool to verify any body before you commit.

A non-accredited body may offer a lower price. But if the certificate isn’t recognised where it needs to be, you’ll end up paying twice.

What to look for in an ISO 27001 certification body

Accreditation is the starting point, but once you’ve confirmed a body is accredited, a few more things are worth checking.

Why certification matters for procurement

ISO 27001 certification is increasingly a commercial prerequisite in Australia, not just a compliance exercise. Government procurement teams, enterprise buyers, and cyber insurers routinely ask to see your certificate before awarding contracts or completing vendor risk assessments.

The body you choose determines whether that certificate opens doors or gets questioned, and whether it’ll still be recognised in three years’ time. An accredited certificate carries weight in government tenders, enterprise supply chains, cyber insurance applications, and APRA-regulated environments.

For Australian businesses, it demonstrates a genuine commitment to protecting data, managing cyber security risks, and maintaining business continuity through sound risk management practices.

A certificate from a non-accredited body won’t be accepted by the procurement teams, regulators, and financial institutions that need to verify it.

What to ask before you commit to an ISO 27001 certification body

When comparing ISO 27001 certification companies, ask these questions of any certification body you’re considering.

  • Is the certification body JAS-ANZ accredited and is that accreditation current?
  • Does the body have experience auditing organisations in your industry?
  • Can they clearly explain the structured two-stage audit process – the initial certification audit and the on-site assessment?
  • Are fees transparent across the full three-year certification cycle?
  • Is there a clear separation between their certification and advisory services?
  • How do they communicate non-conformances and support you in resolving them?
  • Do they offer preparation resources, such as gap analysis tools or training?

How to choose an ISO 27001 certification company

Not all ISO 27001 certification companies audit the same way. Certification is valid for three years and the body you choose on day one manages your annual surveillance audits in years one and two as well as the full recertification audit in year three.

Choose somebody willing to raise honest findings, not just confirm that nothing has changed. New systems, new suppliers, changes in how you handle sensitive data all introduce new security risks that affect your security posture. A rigorous auditor reviews your risk treatment plans, checks that security requirements are being met, and flags gaps in your internal processes before they become problems.

That’s worth thinking about before making a decision on price alone. Before you sign, ask how your chosen certification body approaches ongoing support between audit cycles. Knowing what each ISO 27001 audit stage involves puts you in a better position to ask the right questions of any body you talk to.

JAS-ANZ accredited ISO 27001 certification companies are independent organisations that JAS-ANZ, the Joint Accreditation System of Australia and New Zealand, has assessed and approved to audit Information Security Management Systems (ISMS) and issue ISO 27001 certificates.

JAS-ANZ is the government-appointed body that grants that accreditation and is part of the International Accreditation Forum (IAF). This means that JAS-ANZ accredited certificates are mutually recognised by accreditation bodies globally. The external audit your organisation undergoes is conducted by one of these accredited bodies. Verify accreditation status via the IAF CertSearch tool before you commit to anyone.

No. Only a JAS-ANZ accredited third-party certification body can issue ISO 27001 certification. Unlike unaccredited providers, ISO 27001 certification companies that are JAS-ANZ accredited are assessed for competence, impartiality, and audit quality. Non-accredited bodies issue certificates that Australian government procurement teams, enterprise clients, and financial institutions will not accept.

For Australian organisations pursuing certification for commercial or regulatory purposes, JAS-ANZ accreditation is non-negotiable.

The difference is that a certification body independently audits an organisation’s ISMS and issues the ISO 27001 certificate, while a consultant helps design, build, and prepare the ISMS before the audit. These roles must stay separate. A body that also advises on how to pass its own audit creates a conflict of interest that undermines the certificate’s credibility – and procurement teams may reject it.

The IAF CertSearch tool, which is maintained by the International Accreditation Forum, lets you verify whether a body holds current JAS-ANZ accreditation and whether specific ISO 27001 certified companies hold valid certificates. It takes a few minutes. Any body that doesn’t appear isn’t formally accredited and can’t issue certificates that Australian government bodies or enterprise clients will accept.

Maintaining ISO 27001 certification requires ongoing work across your internal processes and management systems. It’s not just about passing the initial certification audit. Each year, your certification body conducts a surveillance audit to verify that your ISMS is operating effectively. This includes reviewing your internal audit findings, management review records, risk treatment plans, and whether security controls such as access management are functioning as intended.

At the end of year three, a full re-certification audit reassesses your entire ISMS against the existing security controls and practices you have in place. Your certification body will look for evidence of continual improvement – using key performance indicators to measure how your security posture has developed over the cycle.

Australian organisations that treat certification as a living program rather than a one-time achievement get significantly more value from it, and find renewing their ISO 27001 certification far more straightforward.

Obtaining ISO 27001 certification typically takes between three and twelve months. Australian organisations with documented security controls and a clearly defined ISMS scope can reach certification in three to six months. Organisations that are earlier in their ISO 27001 implementation – building an ISMS from scratch – generally need six to twelve months of preparation before the formal audit begins.

The primary factor in timeline is ISMS readiness, not the certification body. Though reputable ISO 27001 certification companies will assess your readiness and give a realistic timeline from the outset.

Not quite. ISO 27001 certification typically runs over a three-year cycle, including annual surveillance audits in years one and two, followed by a full recertification audit in year three. When comparing ISO 27001 certification providers, it’s important to consider the total cost across the certification cycle.
