Penetration testing in Melbourne
Ethical hackers break into your systems before real attackers do. Key IT runs penetration testing in Melbourne to find exploitable gaps a scan misses.
We walk the attacker's path — before they do
A real break-in is rarely one big hole. It's small, easy-to-miss weaknesses chained together. Here's the path our testers follow — so you can close every door, in order.
Then you get the map: every step ranked by severity, with plain-English fixes — and a retest to prove the doors are shut.
A penetration test is a controlled, ethical cyber-attack on your own systems. Skilled testers — with your written permission and inside agreed rules — actually try to break in, the way a real attacker would. They chain small weaknesses together in ways an automated scan never could, prove what an attacker could really reach, and hand you a clear report you can act on. Key IT runs penetration testing for Melbourne businesses, so you find the exploitable gaps and close them before someone else finds them first.
Penetration test vs vulnerability scan — what's the difference?
Here is the simplest way to picture the difference. A vulnerability scan is an automated tool that checks your systems against a long list of known weaknesses and produces a report — broad, fast, and run regularly. It tells you what looks wrong. A penetration test is a person. A skilled tester takes those weaknesses and actually tries to exploit them, combining several minor issues into a real break-in the scanner would have rated as harmless on their own. Scanning gives you breadth and continuous coverage; a pen test gives you depth and proof of genuine business impact.
That is why we pair them: continuous vulnerability scanning & management for everyday hygiene, and a periodic penetration test to confirm what an attacker could truly do.
Types of penetration test we run
External network test
We attack your internet-facing systems — website, email, firewalls and remote access — the way an outside attacker would, with no inside help. This finds the holes someone could use to get in from anywhere in the world.
Internal network test
We assume an attacker is already inside — through a phished staff member or a plugged-in device — and see how far they could spread. This shows whether one compromised laptop could reach your servers, files and backups.
Web application test
We probe your customer portal, booking system or web app for flaws like broken logins, exposed data and injection attacks. This matters for anything that handles payments, accounts or personal information on the public internet.
Wi-Fi and wireless test
We test your wireless networks for weak encryption, rogue access points and guest networks that quietly reach internal systems — the gaps that let someone in your car park, not just inside your building, onto your network.
Social engineering and phishing
With your sign-off, we test your people, not just your technology — simulated phishing emails, pretext phone calls and the like — to see who clicks and what an attacker could get. People are the most targeted way in.
Cloud configuration test
We review your Microsoft 365, Azure or other cloud setup for the misconfigurations behind most cloud breaches — over-shared files, weak access rules and exposed storage that a default setup quietly leaves open.
How a penetration test works
Scope and rules of engagement
First we agree exactly what gets tested, when, and what is off-limits — in writing. This rules-of-engagement document gives our testers legal authority, protects your live systems, and sets emergency contacts so there are no surprises.
Reconnaissance
Our testers map your environment the way an attacker would — finding systems, services and exposed information, and building a picture of your attack surface before they touch anything. The more they learn, the more realistic the test.
Exploitation and testing
This is the real work: testers actively try to break in, exploit the weaknesses they find, and chain them together to see how far they can get — carefully, to confirm genuine risk without disrupting your business.
Reporting with risk ratings
You get a clear written report ranking every finding by severity, with proof of what was reached and plain-English guidance on how to fix it. An executive summary covers the business picture; the detail helps your IT team act.
Retest and verify fixes
After you have fixed the issues, we come back and test again to confirm each one is genuinely closed — not just marked done. You finish with documented proof the gaps are gone, ready for insurers or customers.
What you get
- A clear written report you can actually read — findings explained in plain English, not just raw scanner output.
- An executive summary for owners and boards: the real business risk, in one page, without the jargon.
- Every finding ranked by severity, with proof of exactly what our testers were able to reach.
- Practical fix guidance — what to address, in what order, and how — so your IT team knows precisely where to start.
- A retest after you have made fixes, confirming each issue is genuinely closed.
- Documented evidence you can show cyber-insurers, enterprise customers and auditors who now ask for it.
Who needs a penetration test
If you handle customer data, take payments online, or your business would grind to a halt without its systems, a penetration test answers the question a scan cannot: could someone actually break in? Increasingly the decision is made for you. Cyber-insurers now ask for one before they will cover you or renew — an automated scan counts as weak evidence on its own. Enterprise customers want proof before they sign contracts. Standards and frameworks expect it. And any business that has grown, moved to the cloud, or launched a new app has a fresh attack surface no one has properly tested.
- You store customer, patient or financial data.
- Your cyber-insurer or a big customer is asking for proof.
- You have launched a new website, app or cloud system.
- You have never had an independent test of your defences.
Done safely, without disrupting your business
A common worry is that testing will break something or take systems down. Done properly, it does not. Before anything starts, we agree clear rules of engagement: what is in scope, what is off-limits, and which hours suit you — often outside business hours for sensitive systems. Our testers work carefully and stay in constant contact, so if anything sensitive comes up, you hear about it straight away rather than reading it in a report weeks later. The aim is to prove what an attacker could do, not to cause an outage. You stay in control of the test the entire time, and serious findings are flagged to you the moment they are confirmed — not held back.
- Agreed scope and testing windows, in writing, before we start.
- Careful, controlled testing — proving risk, not causing outages.
- A direct line to our testers throughout the engagement.
- Critical findings reported to you immediately, not held for the report.
Frequently asked questions
What is a penetration test?
It is a controlled, ethical cyber-attack on your own systems. Skilled testers — with your permission — try to actually break in the way a real attacker would, then give you a clear report of every weakness they found and how to fix it. It shows you what could genuinely go wrong before a real attacker does.
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is an automated tool that lists known weaknesses — broad and run regularly. A penetration test is a skilled person who actually tries to exploit those weaknesses and chain them into a real break-in. Scanning gives you breadth; a pen test gives you depth and proof. You want both.
Will a penetration test break things or take our systems down?
Done properly, no. We agree clear rules in advance — what is in scope, what is off-limits, and when to test — and our testers work carefully and stay in contact throughout. Sensitive systems are often tested outside business hours. The aim is to prove risk, not cause an outage.
How long does a penetration test take?
It depends on size and scope. A typical external test runs a few days; an internal network or web application test usually takes one to three weeks of active testing. Counting scoping, reporting and a retest, the whole engagement often spans four to six weeks.
How often should we have a penetration test?
Most businesses test at least once a year, and again after any major change — a new website or app, a cloud migration, an office move or a big growth spurt. Each significant change creates a new attack surface that has not been tested yet.
Do cyber-insurers actually require a penetration test?
Increasingly, yes. Many insurers now ask for one before they will cover you or renew, and they treat an automated scan as weak evidence on its own. They want proof of validated, exploitable risk. A clean, documented penetration test can also help your case at renewal and at claim time.
We already have an IT provider or MSP — do we still need one?
Yes, and ideally from someone independent. A penetration test checks whether the defences your provider has built actually hold up against a determined attacker. An honest external test is a healthy second opinion, not a criticism of your IT team.
What does the report actually look like?
A clear written document, not raw scanner output. It opens with a one-page executive summary for owners and boards, then lists every finding ranked by severity, with proof of what our testers reached and plain-English steps to fix it. After you make fixes, we retest and confirm they are closed.
How much does a penetration test cost?
It is scoped to your environment — the size of your network, the number of applications, and the types of testing involved all shape the price. We agree the scope and a fixed price up front, with no surprises. The best way to get a real figure is a quick conversation about what you need tested.
Is penetration testing legal?
Yes — when it is authorised. That is what the rules-of-engagement document is for: it gives our testers your written permission to test the specific systems you own, within agreed boundaries. We never test anything you have not signed off on.
