Penetration Testing Companies in Australia: How to Choose the Right Partner
Penetration testing companies in Australia help organisations identify security vulnerabilities before attackers exploit them. The best providers use certified ethical hackers, such as CREST accredited professionals, to perform manual testing of web applications, networks, APIs, cloud environments, and mobile systems. Unlike automated vulnerability scans, penetration testing simulates real-world attacks to uncover business logic flaws and hidden security risks.
When choosing a penetration testing provider in Australia, organisations should prioritise CREST accreditation, human-led testing, clear reporting, remediation support, and alignment with frameworks like ISO 27001, APRA CPS 234, PCI DSS, and the ASD Essential Eight. High-quality providers also deliver executive-level reporting and re-testing to ensure vulnerabilities are fully resolved.
Penetration testing companies in Australia are cybersecurity providers that simulate real attacks to identify system vulnerabilities. The best companies are CREST accredited and use manual testing rather than automated tools. They help businesses meet compliance requirements like ISO 27001 and APRA CPS 234 while improving real-world security.
If you’ve spent any time searching for penetration testing companies in Australia, you already know the problem. Everyone says they’re “the best.” Everyone has a logo wall. And half of them will happily sell you an automated scan dressed up as a real test. So let’s skip the sales pitch for a minute and talk honestly about what actually matters when you’re choosing a partner to break into your own systems — and where we, Borderless CS, fit into that picture.
We’ve been doing this long enough to know that the businesses who get the most value out of a pen test aren’t the ones with the biggest budgets. They’re the ones who asked the right questions before signing anything. This guide is built around those questions.
Why this decision matters more than it used to
A few years ago, penetration testing was something you did once a year to keep an auditor happy. That world is gone. The Australian Cyber Security Centre keeps reporting that incidents are climbing, and the cost of a single breach now routinely runs into the millions once you add up downtime, legal exposure, and the customers who quietly never come back.
At the same time, the regulators have caught up. If you operate in banking or finance, APRA’s CPS 234 expects you to test your controls. Aiming for ISO/IEC 27001:2022 certification? Several of its controls effectively assume you’re doing regular, competent security testing. Working toward the ASD Essential Eight? Same story. So choosing among penetration testing companies isn’t an IT housekeeping task anymore — it’s a governance decision that lands on the desk of your CISO, your board, and increasingly your biggest customers during their vendor due diligence.
Which raises the obvious question.
What actually separates good penetration testing companies from the rest
Here’s the uncomfortable truth: the gap between a genuinely good pen test and a box-ticking one is enormous, and from the outside they can look identical. Both produce a report. Both have a price tag. One of them actually makes you safer.
After years of cleaning up after weaker tests, these are the things we’d tell a friend to look for.
1. Real CREST accreditation, not "CREST-style"
CREST is the international benchmark for offensive security. To hold it, a firm has to prove its methodology, its people, and its ethics stand up to independent scrutiny — and keep proving it. A lot of vendors use words like “CREST-aligned” or “industry standard” precisely because they don’t hold the accreditation itself.
Borderless CS is one of the few Australian firms accredited under both CREST ANZ and CREST International. Our CEO also sits on the board of CREST Australia New Zealand. We mention that not to brag, but because it tells you the standard isn’t something we bought a sticker for — it’s something we help maintain for the whole industry.
2. Humans doing the testing, not just tools
Automated scanners are useful. They are also widely available, and your attacker has the same ones. The vulnerabilities that actually sink businesses — chained logic flaws, broken access controls, the authentication bypass that only shows up when a human gets curious — are the ones a scanner walks straight past.
Every Borderless CS engagement is led by an experienced tester doing manual, hands-on work, mapped to recognised methodologies like the OWASP Top 10, PTES, and NIST SP 800-115. The scanner is where we start, not where we stop.
3. A report your board can actually read
Plenty of penetration testing companies will hand you a 90-page PDF, most of it raw scanner output, and consider the job done. Then it sits in a drawer because nobody internally can translate it into action.
We write two things into every report: a plain-English summary your executives and board can absorb in five minutes, and prioritised, specific remediation guidance your engineers can actually implement. Findings are ranked by genuine business risk — not just a raw severity score that treats every issue as equally urgent.
4. They help you fix it — and check the fix
Finding the holes is half the job. The half that protects you is closing them. We stay involved through remediation and re-test the fixes to confirm they actually worked, rather than disappearing the moment the invoice clears.
5. Independence you can trust
Some providers sell you the test and then, surprise, sell you the products to fix what they found. We don’t resell security tooling. Our findings aren’t a sales funnel for someone else’s licences — which means when we say something is a real risk, that’s the only reason we’re saying it.
What we test at Borderless CS
Different businesses are exposed in different places, so a one-size test helps no one. Our penetration testing services cover the full attack surface:
- Web application testing — OWASP Top 10, injection, cross-site scripting, broken authentication and privilege escalation across the apps your customers and staff rely on.
- Network and infrastructure testing — internal and external testing that maps the real paths an attacker would take through your environment.
- Cloud security testing — AWS, Azure and Microsoft 365 configuration review and exploitation, because most modern breaches start with a cloud misconfiguration or a weak identity.
- API and mobile testing — REST and GraphQL APIs, plus native iOS and Android applications.
- Red team exercises — goal-based adversary emulation using the MITRE ATT&CK framework to test not just your defences, but your ability to detect and respond.
- Compliance-driven testing — fixed-scope engagements aligned to PCI DSS, APRA CPS 234, the Essential Eight, and sector-specific needs in healthcare and finance.
How a Borderless CS engagement actually runs
Good testing shouldn’t feel like a black box. Ours runs in four clear stages so you always know what’s happening and why.
Scope. We sit down with you and agree exactly what’s being tested, the rules of engagement, and what success looks like. No scope creep, no surprises on the invoice.
Test. Our testers go to work manually, safely simulating the techniques a real attacker would use against the agreed targets.
Report. You get a board-ready summary plus a technical breakdown, with every finding prioritised by business impact and paired with a clear fix.
Remediate. We support your team through the fixes and re-test to verify they held. Then you have evidence — for your board, your auditor, or your biggest customer — that the work was done properly.
How to choose between penetration testing companies in Australia
If you only take five questions into your next vendor conversation, make them these:
- Are you actually CREST accredited, and can you show me?
- Who personally will be testing my systems, and what’s their experience?
- How much of this is manual versus automated?
- What does your report look like — can I see a sample?
- Do you support remediation and re-test the fixes?
Any provider worth hiring will answer all five without flinching. If the answers get vague, that tells you everything you need to know.

Frequently Asked Questions
1. How much does penetration testing cost in Australia?
Pricing depends on scope — the size of your environment, the type of testing, and the depth required. A focused web application test sits at a very different price point to a full red team engagement. The honest answer is that any reputable provider will scope your specific situation before quoting. We give fixed, transparent pricing once we understand what you actually need tested.
2. How long does a penetration test take?
Most engagements run from a few days to a couple of weeks of active testing, plus reporting time. We agree the timeline up front during scoping so it fits your deadlines, including audit or compliance dates.
3. How often should we run a penetration test?
At least annually is the common baseline, and after any major change to your applications or infrastructure. Many regulated businesses test more frequently. If you’re chasing or maintaining ISO 27001, PCI DSS or APRA CPS 234, your framework will often guide the cadence.
4. What services do MSSPs provide?
MSSPs typically provide SOC monitoring, threat detection, MDR, penetration testing, cloud security monitoring, incident response, and compliance support.
5. What is a Managed Security Service Provider?
A Managed Security Service Provider (MSSP) is a company that provides outsourced cybersecurity services such as SOC monitoring, threat detection, penetration testing, incident response, and vulnerability management.
6. What's the difference between a vulnerability scan and a penetration test?
A vulnerability scan is automated and tells you what might be wrong. A penetration test has a skilled human safely exploiting those weaknesses to show you what an attacker could actually do. Scans are a starting point; real penetration testing companies do the manual work that follows.
7. Is Borderless CS CREST accredited?
Yes. Borderless CS is accredited under both CREST ANZ and CREST International — one of the few Australian firms to hold both — and our CEO serves on the board of CREST Australia New Zealand.
