A penetration test isn't a scan.
Automated tools find the obvious. Senior, manual, methodology-led testing finds what they miss — and reports it so your team knows what to fix first.
Industry-renowned expertise on every engagement.
Core Sentinel was founded by industry-renowned security veteran Steve McLaughlin, who has worked with high-profile and multinational organisations worldwide. Engage us and you get that calibre of expertise directly — not a junior consultant on their first week.

Their penetration testing is incredibly detailed, delivered quickly, and at a price that fits our budget. The hardening guidance is straightforward and practical — total peace of mind for us and our clients.— Michael R., Managed Service Provider
Penetration testing services — common questions.
Who provides penetration testing services in Australia?
Core Sentinel is a Sydney-based, Australia-wide penetration testing company. Every engagement is delivered by a senior, OSCE/OSCP-certified tester — no junior bench, no automated scan-and-send. See everything we cover in penetration testing across Australia.
How much do penetration testing services cost in Australia?
Engagements are fixed-price and quoted up front from the scope — the number of applications, IP ranges and users, and the depth of testing. Send us your scope and you get a clear, fixed quote with no surprises.
Are you CREST certified?
Our testers hold OSCE and OSCP — the hands-on offensive-security certifications — backed by 20+ years and 30+ professional certifications. Every test is senior-led and manual.
Can you test against Essential Eight, ISO 27001, APRA CPS 234 or ST4S?
Yes. We scope engagements to the framework you report against — the Essential Eight, ISO 27001, SOC 2, APRA CPS 234, PCI DSS, IRAP, the SOCI Act and ST4S — and map every finding to the control it affects. See our penetration testing for compliance guide.
How fast can you start, and how long does a test take?
We scope quickly and agree a start date and rules of engagement up front. A typical application or infrastructure engagement runs a few days to two weeks of active testing, followed by a prioritised report and a free re-test.
