Penetration testing, also called pen testing or intrusion testing, is an authorised simulated cyber attack on your applications, networks or cloud systems. Certified testers use the same techniques as real attackers to find weaknesses, safely prove which ones can be exploited, and show you what to fix first.
Unlike an automated vulnerability scan, a penetration test is led by people. Testers chain small issues together, test business logic and confirm real impact, so you get a short list of genuine risks instead of thousands of possible ones.
In Australia, organisations use penetration testing services to meet compliance requirements, answer customer and insurer security questionnaires, prepare for audits and check new systems before they go live.

Who tests you matters as much as what they find. Borderless CS is independently accredited for penetration testing by CREST ANZ and CREST International, our testers hold recognised industry certifications, and our practice is directed by Jaya Prakash (JP) Muthusamy, a Board Director of CREST ANZ.
A pen test shows you where your security gaps are, how they could affect your business, and what needs to be fixed first.
The risk is real. In 2024 to 25, Australian businesses reported average cybercrime losses of $56,600 for small businesses, $97,200 for medium businesses and $202,700 for large organisations, and ASD received a cybercrime report every 6 minutes, according to the ASD Annual Cyber Threat Report 2024 to 25. A penetration test starting from $3,500 costs a small fraction of one incident.
Attackers are also getting faster. Our Q3 2026 Threat Intelligence Report notes Mandiant guidance putting mean time to exploit at minus 7 days, which means exploitation can start before a patch exists. During the quarter, ASD’s ACSC also issued alerts on active exploitation of internet-facing platforms in Australia. Testing finds these weaknesses before attackers do.

What attackers targeted in Australia from July to September 2026, the Q4 forecast and a 90-day action plan.
Not sure which type of testing you need? Every organisation has a different attack surface. Here is the full range, so you can match it to your situation.
Logins, roles, sessions and business logic tested against the OWASP Top 10 and beyond.
REST and GraphQL APIs tested for broken authorisation, data exposure and abuse.
Internet-facing systems, VPNs and remote access, the first doors attackers try.
What an attacker could reach from inside, including Active Directory and lateral movement.
iOS and Android apps, local data storage and the APIs behind them.
Azure and AWS identity, storage and configuration weaknesses.
Wi-Fi security, guest isolation and rogue access points.
Manual review of code for flaws that testing alone can miss.
Prompt injection, data leakage and access control in AI-enabled products.
Ongoing monitoring and expert review between scheduled tests.
Tenant isolation and access control between customers.
Testing that supports Best Practice Software partner integration approval.
Many buyers are offered a scan when they need a pen test, or a one-off test when their systems change every week. This is how the options compare.
If you need penetration testing as a service rather than a single test, our Continuous Monitoring and Assurance service combines vulnerability monitoring, security reviews and expert analysis between scheduled penetration tests, so your assurance keeps up with your changes.

Penetration testing in Australia is priced on scope. A single web application test with Borderless CS starts from $3,500, and every engagement gets a fixed quote after a free scoping call, so you know the full cost before testing starts. Be cautious of very cheap quotes, which are often automated scans sold as a pentest.
Every engagement gets a fixed quote after a free scoping call. Starting prices cover a single, small scope (for example one web application with up to two user roles). Price depends on the number of applications, APIs, IP addresses, user roles and the testing approach.
Penetration testing supports most of the frameworks Australian organisations answer to. Some require it outright, and others expect evidence that your controls work.

Penetration testing, also called pen testing or intrusion testing, is an authorised simulated cyber attack on your applications, networks or cloud systems. Certified testers use real attack techniques to find weaknesses, safely prove which ones can be exploited, and show you what to fix first.
Penetration testing in Australia is priced on scope. A single web application test with Borderless CS starts from $3,500, while combined application, network and cloud engagements cost more. The main cost drivers are the number of applications or IP addresses, user roles and the testing approach. Every engagement gets a fixed quote after a free scoping call.
Active testing usually takes 3 to 15 business days depending on scope. A single web application or API often takes 3 to 5 days. From kick-off to final report, most engagements take 2 to 4 weeks.
Most organisations test at least once a year, and after significant changes such as a new system, major release, cloud migration or security incident. PCI DSS requires penetration testing at least annually and after significant change.
There is no single law requiring every business to run one, but many frameworks do. PCI DSS requires it, APRA CPS 234 requires systematic testing of security controls, and government buyers, enterprise customers and insurers increasingly ask for a recent penetration test report.
A vulnerability assessment uses automated scanning to list possible weaknesses. A penetration test goes further: a certified tester manually confirms which weaknesses are real and exploitable, removes false positives and shows what an attacker could actually reach.
Penetration testing as a service, or PTaaS, provides ongoing security testing and monitoring instead of a single annual test. Borderless CS delivers this through Continuous Monitoring and Assurance, combining vulnerability monitoring, security reviews and expert analysis between scheduled penetration tests.
We offer web application, API, external network, internal network, mobile application, cloud, wireless, AI and SaaS application penetration testing, plus source code security review and testing for Best Practice Software partner approval.
An executive summary, risk-rated findings with evidence, business impact, step-by-step remediation advice and framework mapping where relevant. You also get a debrief with the testers, retesting of fixes and a Letter of Attestation.
No. Automated and AI tools are useful for finding known issues quickly, but they miss business logic flaws, broken access control and chained attacks that need human judgement. Our testers use tools to speed up the work and then confirm every finding manually.
Certified Borderless CS consultants, holding CREST and OSCP certifications, perform every test. There is no offshore testing team, and the testers who do the work also run your debrief.
External testing attacks your internet-facing systems, such as websites, VPNs and email, the way an outside attacker would. Internal testing starts from inside your network, like a compromised laptop or staff account, and shows how far an attacker could move from there.
Not when it is planned properly. Rules of engagement are agreed upfront, denial-of-service testing is excluded unless you ask for it, and riskier tests can run out of hours or against staging.
It is not mandatory, but testing helps you validate your Essential Eight controls by finding exploitable weaknesses attackers could use.
Yes. ISO 27001:2022 Annex A control 8.8 covers the management of technical vulnerabilities, and a penetration test report with retesting evidence shows auditors that vulnerabilities are being found, rated and fixed.
Yes. Many insurers ask about recent security testing when quoting or renewing a policy. A current pentest report and Letter of Attestation give clear evidence of the controls you have in place.
Check CREST accreditation, the certifications of the actual testers, how much of the testing is manual, whether retesting is included, how your data is handled and whether the price is fixed upfront. Ask for a sample report before you commit.
Yes. Borderless CS has offices in Melbourne, Sydney, Brisbane, Canberra, Perth, Adelaide, Darwin and Hobart, and tests organisations across Australia. Most application and external testing runs remotely, and on-site testing can be arranged where needed.
A penetration test tries to find as many exploitable weaknesses as possible in an agreed scope, such as an application or network. Red teaming is a longer, goal-based exercise that tests whether your people, processes and detection can stop a realistic attacker. Most organisations start with penetration testing.
Yes. Borderless CS is certified to ISO 27001:2022 and SOC 2 Type II, testing is done by our own consultants with no offshore testing team, and evidence is stored securely and only shared with your nominated contacts.
Book a free scoping call. We confirm your scope and any compliance requirements, send a fixed quote, usually within 24 hours, and can typically begin testing within a few weeks.
A professional penetration testing service includes scoping, manual testing by certified consultants, safe exploitation of confirmed weaknesses, a risk-rated report with evidence and fixes, a debrief, retesting after you fix the issues, and a Letter of Attestation for auditors, insurers and customers.
