Parent scope
Your Australian entity is a subsidiary of a US-listed parent, and group finance has just sent through a SOX control matrix.
Sarbanes-Oxley · ITGC
A US parent's filing obligation lands on your IT team as a control matrix nobody here wrote. We build the IT general controls behind it — access, change, development and operations — inside your own systems, and evidence them across the whole period so the auditor's testing has something to land on.
Fixed fee agreed after scoping
The systems, controls and support included are confirmed before work begins.
Teams in Melbourne and Sydney. Delivered across all Australian states and territories, remotely or onsite by arrangement. New Zealand and Asia Pacific by arrangement.
We build and evidence the controls so management can make its Section 404(a) assessment. The 404(b) attestation is performed by a PCAOB-registered audit firm — never by us.
/ Delivery team
The written scope identifies the accountable readiness lead, the systems and controls being assessed and any specialist support required for the agreed work.
Our team combines implementation, audit, security-governance and technical expertise. Across their professional careers, team members have delivered 2,000+ hours of ISO, ISM and GRC audit work across 70+ organisations.
Qualifications, professional credentials and formal training held across Aegentra’s delivery team.
Further training and audit qualifications across the team include ISO/IEC 42001 Lead Implementer training, ASD ISM General and Technical audit codes, ISO/IEC 27017 and ISO/IEC 27018 audit codes, and ISO 9001 and ISO 19011 audit qualifications.
Credentials are held across the delivery team and matched to assigned roles. The proposal identifies the consultants, responsibilities and relevant qualification evidence before work begins.
The people assigned to your engagement—and the experience and qualification evidence relevant to their roles—are confirmed in your proposal before work begins.
The engagement record distinguishes Aegentra’s readiness work from management’s assessment and the external auditor’s independent opinion.
Scope
It arrives through ownership, not jurisdiction. If a US-listed parent consolidates your numbers and your entity is material to that consolidation, the group's obligation becomes your control matrix — usually with a deadline attached. Send us the matrix and we'll tell you what is genuinely in scope here.
Send us the control matrixWho it's for
SOX reaches an Australian operation through the group reporting boundary. The engagement starts with the parent's control matrix, the systems that affect the consolidated numbers and the evidence the external auditor expects to test.

Australian delivery boundary
Translate the group matrix into controls, owners and evidence that operate inside the Australian entity.
A readiness engagement fits when
Your Australian entity is a subsidiary of a US-listed parent, and group finance has just sent through a SOX control matrix.
You are preparing for a Nasdaq or NYSE listing and need ITGC in place before the first audited period.
A foreign private issuer with US-listed ADRs, where the Australian systems are material to the consolidated numbers.
Last cycle produced ITGC findings and the parent wants them closed before the auditor comes back.
Controls already built?
We never test controls we built. Use SOX ITGC testing when the control environment is already operating; read the Australia guide for the ownership and listing context.
What we build
If IT general controls fail, the auditor cannot rely on a single automated control in the applications above them — and the testing escalates from a sample to everything.
Who can reach the systems that produce the numbers, and whether that access was approved and remains appropriate.
Whether changes to financial systems were requested, tested and approved before they reached production — and whether the person who wrote the change could also deploy it.
Implementations and migrations that touched a financially-significant system during the period. Auditors treat a mid-year ERP migration as its own control population.
The unglamorous domain: whether scheduled jobs ran, failures were noticed, backups restored, and incidents were tracked to closure.
How it works
Most SOX failures are not design failures. The control exists and works — nobody kept the evidence that it worked in month four.
We work from the group SOX program office’s control matrix and materiality thresholds, not a generic template. The output is an agreed list of in-scope systems and the controls each one carries.
Review the design and operation of the controls within the agreed scope. You get an evidence-based gap register; the external auditor independently determines its own audit procedures and conclusions.
Controls configured inside your own Microsoft 365 tenant and financial systems — access reviews that produce evidence automatically, change approvals that leave a trail, operations monitoring that logs itself.
A control that works today is worthless if you cannot show it worked in March. We agree evidence sources and capture methods, including supported Aeges checks where relevant. Management retains responsibility for the completeness of populations and records.

Not the same thing
The controls overlap. The obligations do not. Scoping one as though it were another is the most expensive mistake in this area.
| SOX ITGC | ISO 27001 | SOC 2 | |
|---|---|---|---|
| What drives it | US securities law | Voluntary certification | Customer due diligence |
| Who tests it | Management testing; external audit where applicable | Independent certification body under an accepted accreditation | Licensed CPA firm |
| Scope | Systems touching the financials | The whole ISMS you define | One service, its criteria |
| Cadence | Annual, with interim testing | 3-year cycle + surveillance | Agreed Type II observation period |
| You end up with | A management assertion | A certificate | An attestation report |
We scope and deliver each of them separately — ISO 27001 implementation and SOC 2 readiness — and map the control overlap so you build shared evidence once rather than three times.
Insights
SOX scoping decisions are expensive to reverse, so it is worth understanding the obligation before anyone quotes on it. These are written by the engineers who do the work — no gated downloads, no form in the way.
FAQ
Start with financial-reporting risks and the processes and information supporting the relevant accounts and disclosures. Trace dependencies through applications, interfaces, reporting tools, infrastructure and access administration. An application inventory alone does not establish SOX scope. Agree the boundary with the responsible finance, legal and audit teams; this is not an assumption that every IT system requires the same controls.
Each control should identify the risk addressed, owner, activity, frequency, evidence and how exceptions are handled. Make it possible to distinguish the control design from proof that it operated. For an access review, identify the population and reviewer, the decision recorded and follow-through on removals. A generic matrix that cannot be connected to actual systems and records is not a substitute for operating controls.
Record the gap honestly and agree its treatment with management and the relevant audit team. Do not backdate approvals or recreate records as if they were contemporaneous. Establish what reliable evidence does exist, whether additional procedures are appropriate and how evidence will be retained going forward. Readiness support cannot promise that a newly implemented control proves effectiveness throughout an earlier period.
Not as Australian law — it reaches you through ownership and US market plans. Your Australian entity is in scope when it is a subsidiary of a US-listed parent or SEC registrant and is material to the group’s consolidated financial statements, when you are preparing for a Nasdaq or NYSE IPO, or when you are a foreign private issuer with US-listed ADRs. In those cases the IT General Controls over your financially-relevant systems have to meet SOX standards, with scope and any external attestation requirements confirmed by the group’s finance, legal and audit teams.
Section 302 is a per-filing certification: the CEO and CFO personally certify, in every 10-Q and 10-K, that the financial statements are accurate and that they have evaluated the disclosure controls behind them. Section 404 is an annual assessment of the control system itself — 404(a) requires management to formally assess and report on the effectiveness of internal control over financial reporting, and 404(b), where applicable to the issuer, requires external-auditor attestation. Emerging growth companies can be exempt from 404(b); confirm the issuer’s status and other exemptions with its advisers.
No, and the distinction is deliberate. This page is readiness — we scope, remediate and build the controls, then set up the evidence capture. SOX ITGC testing is the independent testing of controls someone else built, supporting management’s 404(a) assertion. We do not test controls we built ourselves; that would defeat the purpose of the testing.
A useful amount, but less than people hope. Your Annex A controls for access, change and operations map onto the ITGC matrix, and mature evidence practices carry across directly. What does not carry across is scoping and rigour: SOX scopes tightly to systems that touch the numbers and tests to financial-audit standards, which is a higher evidentiary bar than most ISMS internal audits apply. We start by mapping what genuinely covers a SOX control and treat the rest as net-new.
No. The ERP or accounting platform is almost always the centre of scope, and it is rarely Microsoft. What Microsoft 365 usually provides is the identity layer in front of everything — which is why access controls are where we start. Third-party platforms are typically covered through their SOC 1 Type II report and the complementary user-entity controls it assumes you operate; we check those assumptions actually hold.
Earlier than feels necessary. A control has to operate across the period to be testable, so a control built in month eleven has almost no population for the auditor to sample — this can limit the available operating evidence. Start early enough to meet the agreed evidence period; management and the external auditor determine the effect of any evidence gaps.
Management does. SOX makes named executives personally accountable for the assertion, and no consultant can take that on. What we provide is the control environment and the evidence that makes the assertion defensible, plus the workpaper trail the external auditor will ask to see.
