AT A GLANCE

A first-party audit (internal audit) is carried out by, or on behalf of, the organisation itself to check its own controls. A second-party audit (supplier audit) is carried out by a party with an interest in the organisation, such as a customer, or by someone acting for that customer. A third-party audit is carried out by an independent certification body or a regulator. Infracom delivers the first two. Its auditors check your controls against a named standard, contract or policy, report what they find to your management, and take no part in fixing what they audit. Infracom is not a certification body: where you want a mark or a certificate, Infracom gets you ready for the body that awards it. Audit is the independent review tier of Infracom's three-tier model: the auditor reads the advice and the test evidence but produced neither.

Start to end

Where does an audit sit, from build to assurance?

An audit is the last of three stages: build, validate, assure. It gives an independent opinion on work that other people built and tested. On its own it finds the gaps. With the other Infracom services, the gaps are closed, tested and then audited.

Stage 3 · Assure
Assure it independently

An independent opinion your board, customers and regulators can rely on.

One rule holds from start to end: the people who build do not test, and the people who build or test do not give the opinion. See how Infracom keeps the three apart →

  2. BuildThe gaps are closedPolicies, risk register and controls are built through GRC consulting. Where nobody owns security, a fractional CISO runs it. A Data Protection Officer takes the personal data part and a fractional Chief AI Officer the AI part.
  3. ValidateThe systems are testedThe VAPT team tests the systems in scope and retests the fixes. For Government and critical infrastructure projects, the SQEP endorses the design and the go-live.
  4. AssureThe internal auditAn Infracom auditor who took no part in the build checks the finished programme against the standard and reads the test report as evidence. Supplier audits do the same for your key vendors.
  5. AssureThe certificate or the markWhere you want one, the certification body carries out its own audit. Infracom is not a certification body.
  6. Every yearThe cycle repeatsOn an annual audit programme the dates are fixed in advance: build what changed, test it, audit it.
What the service covers

Which audits does Infracom carry out?

Three kinds of work, chosen by where you are today. An audit needs something to audit against, so the first question is always the same: which standard, contract or policy are the controls being checked against?

🏛

Readiness assessment: when nothing is written down yet

For organisations with no policies and no management system. The auditors look at how things are really done and assess that against a published standard chosen with you. The result is a list of gaps and a plan, not a pass or a fail. The gaps are then closed through GRC consulting or by a fractional CISO, and the finished work comes back for an internal audit.

Internal audit: a first-party audit of a running system

For organisations that already operate a management system or a control framework. An audit programme, sampled evidence, nonconformities and observations, and a report that feeds your management review. The auditor reads the latest penetration test report as evidence, and checks the work of whoever runs the programme, your own team or an Infracom fractional CISO, Chief AI Officer or Data Protection Officer.

Supplier audit: a second-party audit on your behalf

For organisations that depend on vendors, outsourcers or system integrators. Infracom audits the supplier for you against your contract, your questionnaire or a named standard, and gives you a rated report you can act on. Where the supplier handles personal data for you, the report also goes to your Data Protection Officer.

Who needs one

Which Singapore organisations need an internal or supplier audit?

Most requests start with someone else asking for proof: a customer, a tender, a regulator or a certification body. These are the situations Infracom is asked into most often.

💼

SMEs asked to prove their security for the first time

A customer questionnaire or a tender asks for evidence of security, and nothing is documented. An audit cannot begin without criteria, so the work starts as a readiness assessment against a published standard such as Cyber Essentials, a tier of the Cyber Trust mark or ISO/IEC 27001. You learn where you stand and what the shortest route to the evidence is.

Organisations working towards Cyber Essentials or the Cyber Trust mark

The Cyber Trust mark is set out in Singapore Standard SS 712:2025 and has five tiers, from Supporter with ten preparedness domains to Advocate with twenty-two. It is valid for three years with an audit every year. Cyber Essentials is the baseline mark and is valid for two years. Both are awarded by certification bodies appointed by the Cyber Security Agency of Singapore. Infracom assesses you against the tier you are aiming for before that body arrives.

ISO/IEC 27001 and ISO/IEC 42001 management systems

Both standards require internal audits at planned intervals, carried out by auditors chosen for their objectivity and impartiality, with the results reported to management. A small team cannot audit its own work. An outside auditor on an annual programme meets the requirement and gives the certification body a clean audit trail to read.

Licensed cybersecurity service providers

Licensed penetration testing and managed security operations centre providers must hold the Cyber Trust mark at Promoter tier or an equivalent, with a grace period to 31 December 2026. A readiness assessment against the Promoter tier, followed by an internal audit each year, keeps the licence condition met.

Critical information infrastructure owners and their suppliers

Owners of critical information infrastructure are audited under the Cybersecurity Act and must hold the Cyber Trust mark at Advocate tier by the end of 2027. They pass those expectations down to the vendors who touch their systems. A supplier audit before the owner's own audit finds the gaps while there is still time to close them.

Financial institutions and enterprises that rely on vendors

The Monetary Authority of Singapore expects financial institutions to keep the right to audit their material service providers and to obtain independent assurance over them. Under the Personal Data Protection Act an organisation stays accountable for personal data it hands to a data intermediary. A second-party audit turns a vendor's questionnaire answers into verified evidence.

Engagement shapes

How is an audit engagement structured?

Three shapes, all with the criteria, the scope and the sample agreed in writing before the work starts. Effort is sized at scoping on the sites, systems and tier in scope.

Single

Single audit: one scope, one report

A readiness assessment, an internal audit or one supplier audit as a defined engagement. Scoping, fieldwork, a rated report and a closing meeting with management. The usual start for an organisation meeting a customer or tender deadline. What the report finds is built through GRC consulting and tested by VAPT before the next audit.

Annual

Annual audit programme: on contract, every year

An annual contract. Infracom holds your internal audit programme: the plan for the year, the audits on their dates, follow-up of earlier findings and the input to your management review. For certified organisations and those holding a mark that is audited yearly. The audit dates are set after the year's penetration test, so the audit reads fresh evidence, and before the certification body's visit.

Supplier

Supplier assurance programme: your vendors, on a schedule

An annual contract for a list of suppliers. Each supplier is placed in a level by risk, from desk review to site visit, audited on a schedule against one consistent method, and reported in one register your procurement and risk teams can use.

Not includedNone of the three is a certification audit. A certificate or a mark is awarded only by a certification body or a regulator, which is a third-party audit. Penetration testing is a separate service delivered by Infracom's VAPT team, and independent review of a system before it goes live sits with the SQEP service. Fixing the findings is not part of an audit: the auditors who report them do not design the remedy.

How it runs

How does an Infracom audit run?

The method follows ISO 19011, the international guideline for auditing management systems, whatever the standard being audited against. Independence is part of the method: the auditors who examine a control are never the people who designed it. It is the same rule that separates the three tiers of Infracom's delivery model.

1

Criteria and scope agreed in writing

The standard and its version, the tier or clauses, the sites, the systems and the sample sizes are fixed before any work begins, so both sides know what the report will and will not say.

2

Audit plan and evidence request

A dated plan names who will be interviewed and what records are needed. Where little is documented, the request is for what exists: system settings, logs, contracts and the people who know.

3

Fieldwork

Interviews, a walk-through of how the work is really done, sampled records and configuration checks on the systems in scope, on site or by remote session.

4

Findings rated by risk

Each finding is tied to the clause or requirement it relates to, supported by the evidence seen, and rated so that management knows what to deal with first.

5

Report and closing meeting

One written report, presented to management in plain business terms. For a supplier audit, the supplier is given its findings and the customer receives the full report.

6

Follow-up

Agreed actions are checked at a follow-up audit or at the next audit in the annual programme, and the record shows what was closed and when. Closing them is build work: your own team, GRC consulting or your fractional CISO does it, never the auditor.

Frequently asked

Common questions about internal and supplier audits

What an audit is, what it is not, and how independence is kept when the same firm also advises.

What is the difference between a first-party, second-party and third-party audit?
The terms come from ISO 19011. A first-party audit is an internal audit, carried out by or on behalf of the organisation itself; an outside consultant doing your internal audit is still first-party. A second-party audit is carried out by a party with an interest in the organisation, such as a customer auditing its supplier, or by someone acting for that customer. A third-party audit is carried out by an independent body, such as a certification body or a regulator, and is the only kind that leads to a certificate.
We have no policies. Can you still audit us?
An audit needs criteria, so with nothing written down the honest first step is a readiness assessment. Infracom agrees a published standard with you, such as Cyber Essentials, a tier of the Cyber Trust mark or ISO/IEC 27001, and assesses how the organisation really works against it: settings on your systems, access to your cloud services, how staff join and leave, how backups are taken. You receive a gap register and the minimum set of documents you need, in the order to write them.
Can Infracom certify us for the Cyber Trust mark or ISO/IEC 27001?
No. The Cyber Trust mark and Cyber Essentials are awarded by certification bodies appointed by the Cyber Security Agency of Singapore, and ISO certificates by accredited certification bodies. Infracom is not a certification body and does not issue marks or certificates. Infracom carries out the readiness assessment and the internal audit that come before, so that the certification audit finds a system that is ready.
Can the consultant who built our system also audit it?
Not the same person. Internal auditors must be objective and impartial, which means they do not audit their own work. Where Infracom has advised a client or holds a retainer role such as fractional CISO, fractional Chief AI Officer or Data Protection Officer, the internal audit is carried out by a different auditor who took no part in that work, the arrangement is declared in writing, and the report goes to your management. Where that separation cannot be kept, Infracom says so and you appoint another auditor.
What is a supplier audit based on?
On what the supplier has agreed to. The criteria are usually the security and data protection clauses of your contract, your own supplier questionnaire, or a named standard the supplier claims to meet. They are fixed with you before the audit, the supplier is told what will be examined, and the audit checks the evidence behind the supplier's answers instead of accepting the answers alone.
Does an audit include penetration testing?
No. An audit examines whether controls exist and operate as stated, through evidence, interviews and configuration checks. Penetration testing attacks the systems to find weaknesses and is delivered separately by Infracom's VAPT team. The two are often scheduled in the same year and their results read together.
How often should an internal audit be carried out?
At planned intervals. In practice a certified management system is audited internally every year, with the whole scope covered across the certification cycle. The Cyber Trust mark is valid for three years with an audit each year. An annual audit programme on contract fixes the dates in advance, so the internal audit is finished well before the certification body's visit.
Does the service cover Australian requirements?
Yes, for internal and supplier audits against ISO/IEC 27001 and for assurance over third parties of the kind APRA's prudential standards expect. Two points of wording matter in Australia. The Essential Eight is assessed against a maturity model; it is an assessment, not an audit or a certification. Assessments under the Infosec Registered Assessors Program are carried out only by assessors endorsed by the Australian Signals Directorate, and Infracom's readiness work comes before that step.
