Penetration testing services in Sydney

An external test starts from the internet and checks what an outside attacker can reach, such as firewalls, remote access and email gateways. An internal test starts inside your network and shows how far an attacker could move after getting a foothold through a compromised device or account. Many businesses start with an external test and add internal testing where they run their own servers or hold sensitive data on site.

A vulnerability scan identifies known weaknesses. A penetration test goes further and attempts to exploit them in a controlled way, within an agreed scope, so you can see what an attacker could do. Think of a scan as checking whether your doors are unlocked. A pen test is someone trying to get in.

Black box testing simulates an external attacker with no prior knowledge of your systems. White box testing gives the tester full access to your environment for a deeper review. Grey box testing sits in between and uses limited but valid user credentials. We recommend the right approach when we scope your test.

No. Small and medium businesses are often targeted because attackers see them as easier targets. Our pen testing services are designed for small and medium businesses, and we size the scope to your environment.

Most Australian businesses benefit from annual penetration testing at a minimum. You should also test after significant changes to your IT environment, such as cloud migrations, new applications or office moves. Some compliance frameworks and cyber insurance policies require testing at specific intervals.

Yes. As well as one-off tests, we offer automated network penetration testing every month, so new vulnerabilities show up as your environment changes. For managed IT clients, our team remediates findings as part of your managed IT agreement.

Testing is designed to keep disruption low. We agree testing windows with you, test critical systems within those windows and keep your team informed throughout. As with any penetration test, exploitation can occasionally interrupt a service, which is why we agree the windows in advance.

It depends on the number of systems, open ports and services in scope, so larger networks take longer. We give you a clear timeline when we scope the test.

We handle most of the preparation during scoping. We’ll need some basic information about your environment, including network diagrams, IP ranges and any systems to exclude. For an internal test, we also set up a small testing agent inside your network.

You receive an executive report for your leadership team and a technical report with prioritised findings, risk ratings and remediation steps. We walk your team through the results. For managed IT clients, we then fix the issues and retest to confirm they’re resolved.

The cost of a penetration test depends on scope, environment complexity and the number of live IP addresses being tested. For Australian SMBs, external network pen testing typically ranges from $4,000 to $12,000 and internal testing from $6,000 to $18,000, depending on network size. Web application testing, wireless assessments and social engineering testing are scoped separately. We provide a clear, fixed quote after an initial scoping conversation.

It depends on your insurer and policy. Some cyber insurance policies ask about penetration testing or require it at set intervals, so check your policy before renewal. A current test report gives you evidence of your security posture to show your insurer. Improving your security posture can also help reduce premiums.

Yes. We map our findings to the Essential Eight mitigation strategies recommended by the Australian Cyber Security Centre, so you can track your maturity level and demonstrate progress to auditors or insurers.

CREST certification is available for internal and external network penetration tests. These tests are delivered through our testing partner, Vonahi Security, which holds CREST accreditation in Australasia. Each CREST-certified report carries the CREST logo on its cover page.

Yes. Our head office is in Caringbah, and we support businesses Australia wide. We scope each test with you and walk your team through the findings. For managed IT clients, we then help fix the issues and retest.
