IT Security Audit in Hong Kong: Scope, Cost and What You Get (2026)

Short answer: an IT security audit in Hong Kong is a structured, evidence-based review of how your systems, accounts, devices and processes are actually configured, measured against a stated baseline, and it ends in a written report with risk-ranked findings and a remediation roadmap. It is different from a vulnerability scan (automated, narrow), a penetration test (an attempt to break in) and a general IT assessment (broader, less evidence-heavy). Cost is driven by headcount, number of sites, scope and how much evidence you can hand over. For a small business with fewer than 20 IT users, Brocent publishes a fixed-scope core audit price on its service page; larger or recurring programmes are scoped and quoted. Which one you need depends on who is asking: an insurer, a client doing due diligence, or a privacy review.

What is an IT security audit, and how is it different from the other things people ask for?

The four terms below are used loosely in sales conversations. Pin them down before you compare quotes, because a quote for one is not a quote for another.

• IT security audit: a structured review of controls against a baseline. It looks at identity and authentication, access permissions, endpoints, assets, patching, backup, software control, mobile devices, and often email and network settings. The output is a written report with findings ranked by risk and a roadmap. It is mostly configuration and evidence review, plus interviews.
• Vulnerability scan: an automated tool run that lists known weaknesses on systems it can reach. Quick and cheap, but it does not check whether your offboarding process works or whether backups restore. See vulnerability management vs penetration testing for the distinction.
• Penetration test: a person tries to break in, within an agreed scope, and reports what worked. It tests how far an attacker gets; an audit tests whether the controls were in place to begin with. Read how penetration testing differs from an audit in Microsoft 365 for the same contrast on one platform.
• IT assessment: the broadest and lightest term. It may cover architecture, cost, risk and strategy, and it is not always evidence-based. Some providers use "assessment" and "audit" interchangeably; ask what evidence each one collects.

A useful test: if the quote does not say what evidence will be collected (exports, screenshots, scan outputs, interviews), you are being offered an opinion, not an audit.

What does a security audit actually cover?

Scope varies, but a baseline audit for a small or mid-size Hong Kong organisation usually covers these areas. The list below follows the published scope of Brocent's SME project audit.

• User accounts and authentication: account inventory, onboarding and offboarding, dormant accounts, multi-factor authentication, privileged and service accounts, conditional access.
• Access permissions: role-based access, file-share and collaboration permissions, group membership, guest and external access, segregation of duties for critical functions.
• Endpoint security: endpoint protection deployment and status, device compliance policies, antivirus update status, firewall settings.
• IT asset management: hardware, software and cloud licence inventory, ownership, lifecycle, disposal procedures.
• Patching and vulnerabilities: operating system and application patch status, the scanning and remediation workflow, patch policy.
• Backup and recovery: coverage, frequency, retention, restore testing and ransomware resilience such as immutable or isolated copies.
• Software control: approval process, shadow IT, licence compliance.
• Mobile device security: policy for company-owned and personal devices, remote wipe, encryption, passcodes.
• Often scoped as add-ons: network and Wi-Fi security, email authentication (SPF, DKIM, DMARC), logging and monitoring, physical access, security awareness, incident response plans, and gap analysis against frameworks such as PDPO or ISO 27001.

If you run Microsoft 365, the identity, access, email and endpoint areas overlap with a Microsoft 365 security audit. That is a separate product line with its own cost and sample report, so this article does not repeat it: see Microsoft 365 security audit cost and the report walkthrough.

What do you get at the end? Sample deliverables

Ask to see the deliverable before you sign. A useful audit hands over:

1. A written report. Findings ranked by risk, each with the evidence behind it, the affected systems and what to do. In Brocent's SME audit this comes with a prioritised roadmap.

2. A debrief session with your IT team and management, so the findings are explained rather than just delivered.

3. A remediation list you can assign to owners and dates.

4. Evidence you can reuse. Many buyers need to answer a questionnaire later. A report that records what was checked and when is far more useful than a verbal "you are fine".

Larger programmes add recurring reporting. Brocent's audit catalogue sets a cadence per audit type: for example an information security audit quarterly, a penetration test semi-annually or annually, and a log and activity audit monthly. For an SME, a one-off baseline followed by a yearly repeat is the more common pattern.

How much does an IT security audit cost in Hong Kong?

There is no standard price, and be wary of any article that quotes one number for every business. What moves the price:

• Number of IT users and devices. More accounts and endpoints means more to inventory and sample.
• Number of sites and systems. Each extra office, server room or cloud tenant adds discovery and interviews.
• Scope. A core baseline costs less than one that adds network review, email security, incident response review and a framework gap analysis.
• Evidence readiness. If you can export user lists, device lists and policy settings quickly, the audit is faster. If everything is in people's heads, the auditor has to reconstruct it.
• Depth of testing. Tool-based scans, interviews and any penetration testing add effort.
• Remediation help. Audit only, or audit plus hands-on fixing.

For a reference point on a small business, Brocent's IT Assessment and Audit page publishes three fixed-price tiers for organisations with fewer than 20 IT users: a core audit covering the eight baseline areas above, a comprehensive audit that adds items such as Microsoft 365 Secure Score review, email security, a basic network and Wi-Fi review, incident response plan review and a PDPO or ISO 27001 gap analysis, and a premium tier with post-audit consulting. The effort estimate on the page is 50 to 80 hours of senior consultant and support time, including scans, interviews and report writing. When this article was written (November 2026), the core audit started from USD 3,800. That is indicative reference pricing shown across Brocent's markets, final quotes can vary by market, and the current figure is on the pricing page for professional services, which is the source to trust if it has changed. Enterprise and recurring programmes are quoted separately.

When you compare any two quotes, line them up on the same list: users covered, sites, areas in scope, evidence collected, deliverables, and whether remediation is included.

Which audit do you need? A guide by trigger

Start from who is asking and why.

• An insurer's questionnaire at renewal. The insurer wants evidence of specific controls such as multi-factor authentication, backup testing and endpoint protection. A baseline audit with a report that records each control is the right fit. If your environment is Microsoft 365, read cyber insurance requirements for Hong Kong IT renewal first.
• A client or supplier doing due diligence. They send a security questionnaire or ask for a recent assessment. Again a baseline audit works, and the report becomes something you can share (with sensitive details removed).
• A privacy review. If your concern is Hong Kong's Personal Data (Privacy) Ordinance (PDPO), you need an audit scope that includes data handling, retention, access control and outsourcing, and often a PDPO gap analysis as an add-on. An audit informs a privacy review but does not replace legal advice.
• A regulated firm's expectations. Licensed financial firms may be asked by their regulator or customers for particular testing. Check what your own regulator expects before choosing scope; for one example, see what HKMA expects for penetration testing at a payments firm.
• An incident or near miss. An audit tells you where the control gaps are; it is not incident response. If something has happened, deal with that first.
• You simply do not know your baseline. A core audit is the cheapest way to find out.

How do you prepare for an audit so it costs less and finds more?

1. Name an owner on your side who can answer questions and grant access.

2. Gather the inventories you already have: user list, device list, software and licence list, network diagram, backup schedule.

3. Write down your policies, even if informal: joiner, mover and leaver steps, password rules, how software is approved.

4. Decide read-only access the auditor will need, and agree in writing what will and will not be touched.

5. Agree the timeline and the debrief before work starts.

6. Know what you are measuring against. A stated baseline, an insurer's list, or a framework. Without one, findings are opinions.

What audits sit beyond the core project?

The core project is scoped for small and mid-sized teams. For larger or more regulated organisations, Brocent's published audit catalogue lists 17 audit services across 7 categories, each with a stated frequency, deliverable and industry fit.

In the security category, for example, an information security audit runs quarterly and covers endpoint protection, remote access and VPN, multi-factor coverage, and password and shared-account practice. Penetration testing and vulnerability assessment run semi-annually or annually. A log and activity audit runs monthly for organisations that need an ongoing view of who accessed or moved data. A data protection and privacy audit is listed on a semi-annual cycle and covers data classification, encryption policy, external sharing and public-link permissions, and backup and recovery.

Each service ends with a written report, and the compliance audits add a gap analysis and a remediation roadmap. You do not need all of them. The practical question is which cycle matches your risk: most smaller teams start with the core audit, then add a recurring cycle for the area where the first report found the most gaps. The IT assessment and audit services page lists the full catalogue. Because each entry states its deliverables, you can compare what you would receive against what an insurer, client or regulator has asked for before you commit to a scope.

How do you choose a provider?

Apply the same discipline as for any security purchase. Ask who actually performs the work and what certifications they hold, ask for a redacted sample report, check the scope is written down, check they have no commercial interest that conflicts with an independent view (for example a provider who audits the environment they also sell), and make sure the contract covers confidentiality and how your data is handled. If you want a broader checklist, how to choose a cybersecurity provider in Hong Kong covers contract clauses, red flags and cost expectations.

Frequently asked questions

Is an IT security audit the same as a penetration test?

No. An audit reviews whether controls are in place and configured correctly, using evidence and interviews. A penetration test tries to break in within an agreed scope. They answer different questions and are often bought together.

How long does an audit take?

It depends on size and scope. Brocent's SME audit is estimated at 50 to 80 hours of consultant and support effort, spread over calendar weeks that depend on how quickly you provide evidence and access.

How often should we audit?

A baseline once, then at least yearly or after major changes. Brocent's catalogue suggests higher frequency for specific audit types, for example quarterly for information security and monthly for log reviews in sensitive environments.

Will an audit satisfy my insurer?

It gives you evidence of the controls the insurer asks about, but each insurer sets its own requirements. Read the questionnaire first and make sure the audit scope covers every control it names.

Do I need a separate Microsoft 365 audit?

Identity, access, email and endpoint settings in Microsoft 365 are covered by the baseline areas above, but Brocent also offers a dedicated Microsoft 365 security audit with its own pricing. Pick one scope so you do not pay twice for the same checks.

Does an audit fix the problems?

Not by itself. The report ranks the findings and gives a roadmap. Fixing is either your team's job or an optional add-on, such as the post-audit consulting hours in the premium tier.

Is this legal advice for PDPO?

No. An audit can show how personal data is handled and where controls are weak, but legal obligations under the PDPO should be confirmed with a lawyer.

Next step

Decide who is asking and why, list the areas that must be in scope, and ask each provider for a redacted sample report and a quote on the same list. To see Brocent's scope and tiers, read the IT assessment and audit service page and the professional services pricing, or talk to a Brocent consultant and describe the questionnaire or review you need to pass.
