Penetration Testing in Melbourne: Costs and Quotes
Siege Cyber is a CREST-accredited company for penetration testing. The accreditation is assessed and held at company level and is verifiable on the CREST member register. If you are collecting penetration testing quotes in Melbourne, that is the credential worth checking first, and checking the scope of, because CREST accredits penetration testing separately from vulnerability assessment, red teaming and incident response.
Melbourne has the broadest industrial mix of any Australian capital, and that is the single most useful thing to know about what penetration testing costs here. A quote for a fintech platform, a quote for a hospital network and a quote for a manufacturer with twenty years of operational technology in the plant are three genuinely different pieces of work. When the numbers come back wildly apart, it is usually not because one provider is gouging. It is because they scoped different things.
What Actually Drives the Price
Five things move a penetration testing quote more than anything else, and all of them are decided before testing starts.
Scope, measured properly. Not “our website” but how many applications, how many user roles, how many API endpoints, how many external IP addresses, how many internal subnets, and which cloud accounts. A provider who quotes without asking for those numbers is guessing, and the guess gets corrected later either by a variation or by a thinner test.
Test type. An external network test is the cheapest common engagement. Web application testing costs more because authenticated, role-aware testing takes days rather than hours. Mobile application and cloud configuration testing sit higher again. Red teaming is a different exercise entirely and should not be compared on price with a penetration test.
How much is automated. This is the biggest hidden variable. A scan with a report attached can be produced in a day. A manual test by an experienced tester who chains findings together takes a week and finds the business logic flaws no scanner will ever see. Both can be called a penetration test in a quote.
Whether a retest is included. Your auditor or your customer will want evidence that findings were fixed, not just found. If the retest is a separate line item you have not budgeted for, the real cost is higher than the number on the page.
Accreditation. A CREST accredited company has to evidence its methodology, reporting standards, data handling and quality processes to an assessor, and re-evidence them to stay accredited. That overhead is priced in. Firms without it price without it.
For the national picture including indicative bands by test type, we keep an Australian penetration testing pricing guide up to date.
Why Melbourne Quotes Vary More Than Most
Melbourne’s industry spread means the buyer and the driver behind the test change more from engagement to engagement than they do in a single-industry city.
- Financial services and fintech. If any part of the business is APRA regulated, or supplies someone who is, testing has to be systematic and at a defensible frequency under CPS 234. That pushes towards a programme rather than a one-off, and programmes are quoted differently.
- Health and aged care. Patient data raises the sensitivity classification, which raises both the depth of testing expected and the standard the report has to meet.
- Manufacturing and logistics. Operational technology environments need testers who understand that you cannot simply throw traffic at a production line. Safe testing in an OT environment takes planning, and planning is time.
- Education and research. Large, old, federated networks with a lot of inherited infrastructure. Scope discovery alone can be a meaningful part of the engagement.
- Professional services and SaaS. Usually driven by a customer security questionnaire or a SOC 2 or ISO 27001 programme, where the test is one deliverable inside a larger compliance timeline.
How to Compare Two Melbourne Quotes Properly
Put the quotes side by side and check these, in this order. It takes about ten minutes and it is the most useful ten minutes in the whole process.
- Is the scope identical? Count applications, IP addresses, user roles and cloud accounts in each. Most price gaps close the moment you do this.
- How many tester days? Not dollars, days. A quote that will not tell you is telling you something.
- Manual or automated? Ask directly what proportion is manual testing, what tooling is used, and what the tester does after the tooling finishes.
- Who is testing? The named individuals, their certifications, and whether they are employees or subcontracted.
- Is the provider accredited, and for what? CREST accredits companies by discipline. Check the discipline, not just the logo.
- What does the report contain? Ask for a redacted sample. It should have reproduction steps, evidence, business impact and specific remediation, not a risk score and a heat map.
- Is a retest included? And is there a time limit on it?
- Who explains the findings? A debrief with the tester who did the work is worth more than a longer report.
The Cheapest Quote Is Sometimes the Right One
This is worth saying plainly, because most articles on this subject are written to justify a higher price. If you have never had a test, your environment is small, and nothing has been looked at in years, a modest external network test will find plenty and cost little. The expensive engagement is the wrong first purchase.
Equally, if the test exists because an auditor or a customer is going to read the report, the cheap option is false economy. A report that does not survive that reading has to be done again, and you have then paid twice.
The question is not what a penetration test costs in Melbourne. It is what the test is for, and who is going to read the output.
Working With a Brisbane-Based Provider
We are Brisbane based and work with Melbourne clients remotely, attending on site where it genuinely helps rather than as a billable default. Same time zone, same regulatory environment, and the people who do your testing are the people who write your report and take your questions afterwards. For operational technology work, where being in the room matters, we plan on-site attendance into the scope from the start rather than adding it later.
Our testing is fixed price, which means the number in the proposal is the number on the invoice, and the scope is written down in enough detail that neither of us can be surprised by it. If you would rather spread testing across a year than buy it in one hit, we can structure it that way.
Getting a Quote
If you want a number, the fastest route is a short scoping conversation. We will ask what is in scope, why the test is happening and who is going to read the report, and quote against that. If the honest answer is that you need something smaller than you asked for, we will say so.
