What Is SOC 2? A Guide for Australian Businesses

SOC 2 is a US-originated audit report that proves a service business handles customer data securely, and Australian businesses usually pursue it because an American customer or investor has asked for it. It is not a certificate and it is not law in Australia, it is an independent auditor's report against five trust criteria. If a US client has put SOC 2 in front of you, here is what it actually means and whether you need it.

Key facts

• SOC 2 is a report produced by an independent auditor against the AICPA Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy.
• It is not a certification or a tick-box; it is an opinion from a licensed auditor about how well your controls are designed and operating.
• There are two flavours: Type 1 (controls at a point in time) and Type 2 (controls operating over a period, usually 3 to 12 months).
• For Australian businesses, SOC 2 is almost always customer-driven, typically by US clients or investors, rather than a local legal requirement.
• Much of the underlying work overlaps with the Essential Eight and ISO 27001, so existing security uplift is not wasted.
• If your buyers are Australian, ISO 27001 or a strong Essential Eight posture is often the better fit than SOC 2.

What is SOC 2 and how is it different from ISO 27001?

SOC 2 is an attestation report, not a certificate. An independent auditor examines your controls against the relevant trust criteria and writes an opinion; you then share that report with customers under a non-disclosure agreement. ISO 27001, by contrast, results in a certificate from an accredited body that anyone can verify. The practical difference matters when you choose between them: SOC 2 is the language US technology buyers speak, while ISO 27001 is the international certificate more common in Australia, Europe, and government-adjacent work. They cover much of the same ground, so a business with one is well placed to pursue the other, but you generally lead with whichever your customers actually ask for.

What is the difference between SOC 2 Type 1 and Type 2?

Type 1 assesses whether your controls are suitably designed at a single point in time, while Type 2 assesses whether they actually operated effectively over a period, usually three to twelve months. Type 1 is faster and is often used as a first step to show intent, but most serious customers want Type 2, because it proves the controls work in practice rather than just on paper. If a customer has asked for SOC 2 without specifying, they almost always mean Type 2. The implication for an Australian SME is that you need a monitoring period with evidence collected throughout, not a last-minute scramble before the audit.

Do Australian businesses actually need SOC 2?

Only if your customers ask for it, and in our experience that means you are selling software or services to US organisations. There is no Australian law that requires SOC 2. If your buyers are Australian, you will get more value from ISO 27001 or a demonstrably strong Essential Eight posture, both of which are better recognised here. We have seen SMEs start down the SOC 2 path because it sounded important, then realise an ISO 27001 certificate would have served their actual market better. So the honest first question is not "how do we get SOC 2" but "who is asking, and is SOC 2 really what they need from us". If a US client has named it in a contract, then yes, it is worth doing properly.

How do you prepare for a SOC 2 report?

The groundwork is the same security hygiene that underpins every framework. You define the trust criteria in scope, document your controls, and then make sure they are genuinely operating: multi-factor authentication everywhere, access control and reviews, change management, logging and monitoring, vendor management, and an incident response plan. For a Type 2 you then run the monitoring period while collecting evidence, before the auditor's fieldwork. Most of this overlaps with an Essential Eight uplift and Microsoft 365 hardening, so if you have already done that work for local reasons, you are a long way toward a SOC 2 report rather than starting from scratch.

Frequently asked questions

Is SOC 2 a certification?

No. SOC 2 is an independent auditor's attestation report, not a certificate. You receive a report describing your controls and the auditor's opinion, which you share with customers, usually under a non-disclosure agreement. ISO 27001 is the framework that results in a verifiable certificate.

Is SOC 2 required by law in Australia?

No. There is no Australian legal requirement for SOC 2. It is driven by customer and investor expectations, most often from US organisations. Australian legal obligations sit under the Privacy Act 1988 and, for some sectors, regulators like APRA.

Should we do SOC 2 or ISO 27001?

Follow your customers. If your buyers are US technology companies, SOC 2 is usually what they expect. If your market is Australian, European, or government-adjacent, ISO 27001 is more widely recognised. They overlap heavily, so doing one makes the other easier later.

How long does SOC 2 take?

A Type 1 can be achieved relatively quickly once controls are in place. A Type 2 requires a monitoring period, commonly three to twelve months, during which evidence is collected before the audit. Plan for the monitoring window rather than expecting an instant report.

If a US customer has asked your business for SOC 2 and you are weighing it against ISO 27001, we can help you work out which one your market actually needs and get the underlying controls in place either way. It is a common question for Sydney businesses selling abroad, and the answer is usually clearer than it first looks. See how we approach compliance or talk to us directly.
