Your attack surface

Queensland Is Growing. So Is Your Attack Surface.

Brisbane organisations are digitising quickly. Councils are moving services online, health providers are connecting patient systems, resources companies are linking site operations to the cloud, and a wave of suppliers is gearing up for major infrastructure and Brisbane 2032 projects.

Every new portal, API and remote connection makes the business easier to run. It also gives attackers one more door to try, and most organisations do not know which of those doors are unlocked.

Pen testing Brisbane: attack surface diagram

Pen testing in Brisbane gives you an attacker’s view of your environment, without the damage.

Our consultants combine manual testing, recognised methodologies and controlled exploitation to confirm which weaknesses are real, how far an attacker could get, and what to fix first. Scanners help, but they never replace a skilled tester.

Whether it is a single customer portal or your whole network, the goal is simple: close the gaps before someone uses them.

WHY IT MATTERS

Why Pen Testing Matters for Brisbane Organisations

Firewalls, endpoint protection and a SIEM tell you what is installed. They do not tell you what an attacker could actually achieve.

Most real breaches come from small issues chained together: a reused password, an API that trusts the wrong user, a cloud role with more access than it needs. Automated tools rarely connect those dots.

A penetration test does. Certified testers look for those chains and, within the agreed scope, safely prove whether they can be exploited.

This gives your organisation a much clearer understanding of:
  • 01Which findings are genuine risks, and which are noise
  • 02The route an attacker would take through your systems
  • 03What data or systems could be reached
  • 04Which fixes will reduce the most risk first
  • 05Whether your fixes actually worked, after retesting
Independent assurance

CREST Penetration Testing Brisbane: Why Accreditation Matters

A penetration tester gets controlled access to some of your most sensitive systems. You need to trust their methods, their people and how they handle your data.

CREST accreditation is independent proof of all three. Borderless CS is a CREST-accredited penetration testing company serving Brisbane and Queensland, and our methodology, processes and testers are assessed against CREST standards.

Borderless CS holds CREST ANZ and CREST International accreditation for penetration testing.

What we test

Penetration Testing Services in Brisbane

Every Queensland environment is different, so we scope each pentest around your systems, your customers and the obligations you need to meet.

Web Application Penetration Testing Brisbane

We test logins, user roles, sessions, business logic and input handling against real attack techniques, including the OWASP Top 10, and show exactly how each issue could be exploited.

API Penetration Testing

APIs often expose more than the app in front of them. We check authentication, object-level access, data exposure, rate limiting and input validation across REST and GraphQL APIs.

External Network Penetration Testing

We assess your internet-facing systems, VPNs, mail and remote access services to find the entry points an outside attacker would try first.

Internal Network Penetration Testing Brisbane

We show what an attacker or compromised staff account could reach once inside: privilege escalation, lateral movement and access to critical servers. On-site testing is available across Brisbane and South East Queensland.

Cloud Penetration Testing

For Microsoft Azure and AWS, we look at identity permissions, exposed storage, insecure configurations and paths from one cloud resource to another.

Mobile Application Penetration Testing

We test iOS and Android apps, how they store sensitive data, how they authenticate, and the backend APIs they talk to.

AI and SaaS Application Penetration Testing

For AI-enabled and multi-tenant SaaS products, we test tenant isolation, prompt injection, data leakage and access control between customers.

Know the difference

Penetration Testing vs Vulnerability Assessment

A vulnerability assessment and penetration test are related, but they are not the same thing.

Vulnerability assessment

Finds what might be wrong

A vulnerability assessment primarily identifies potential security weaknesses across your environment. It is useful for discovering and managing vulnerabilities at scale.

  • Identifies potential weaknesses
  • Broad coverage, largely automated
  • Useful for managing vulnerabilities at scale
VS
Penetration testing

Proves what an attacker could do

A pen test goes further. Our testers manually investigate identified weaknesses and, where appropriate, safely attempt controlled exploitation to understand whether a vulnerability can actually be used and what the potential impact could be.

  • Manual, hands-on investigation
  • Controlled exploitation within scope
  • Validated impact and remediation priority
How it works

Our Brisbane Penetration Testing Process

Every engagement follows the same controlled, transparent path, and our Brisbane office means you can meet the team in person when it matters.

01

Scoping and Consultation

We meet online or at our Ann Street office to understand your systems, goals, deadlines and compliance needs, then agree scope, exclusions, access and timeline.

02

Reconnaissance and Attack Surface Analysis

Our testers map what is exposed and identify the most likely entry points.

03

Manual Security Testing

Consultants test by hand using recognised methodologies and real-world techniques. Tools help, but they do not lead.

04

Controlled Exploitation

Where appropriate and permitted within the agreed scope, identified vulnerabilities are safely validated toWithin the agreed scope, we safely prove whether a weakness can be exploited and how far it reaches. determine whether they can be exploited and what impact exploitation could potentially have.

05

Risk Analysis and Reporting

You receive a risk-rated report with evidence and fix steps, followed by a debrief with the testers who did the work.

06

Remediation and Retesting

Once your team has applied fixes, we retest to confirm each issue is closed.

A single web application test starts from $3,500, and every engagement gets a fixed quote after a free scoping call. Be wary of very cheap quotes, which are often automated scans sold as a pentest.

FAQs

Frequently Asked Questions About Penetration Testing Brisbane

Which penetration testing companies in Brisbane are CREST accredited?

Several Brisbane providers hold CREST accreditation. Borderless CS has an office at 69 Ann Street, Brisbane, and holds both CREST ANZ and CREST International accreditation for penetration testing, which you can verify on the CREST websites.

Cost depends on scope. A single web application test starts from $3,500, while network or multi-application engagements cost more. Borderless CS gives a fixed quote after a free scoping call, so you know the full cost before testing starts.

The most requested are web application, API, external and internal network, cloud (Azure and AWS), mobile application, and AI or SaaS application testing. Borderless CS delivers all of these for Brisbane and Queensland organisations.

Look for CREST accreditation, testers with CREST or OSCP certifications, manual testing, a sample report you can review, and retesting. Borderless CS meets all of these and has a Brisbane CBD office.

Yes. Internal network and wireless testing can be done on site across Brisbane, the Gold Coast, the Sunshine Coast and regional Queensland, or remotely over VPN if that suits your team better.

Active testing usually takes 3 to 15 business days depending on scope. A single web app or API often takes 3 to 5 days. From kick-off to final report, most engagements take 2 to 4 weeks.

At least once a year, and after major changes such as a new release, cloud migration, merger or office move. PCI DSS and many enterprise customers expect annual testing as a minimum.

Queensland Government agencies must run an information security management system under the Queensland Government Information Security Policy (IS18), and many contracts pass security expectations on to suppliers. A recent pentest with remediation evidence is a common way to show your controls work.

If you are a Queensland public sector agency, or you handle personal information on behalf of one, the Mandatory Notification of Data Breach scheme under the Information Privacy Act 2009 applies. Regular penetration testing helps you find and fix weaknesses before they become notifiable breaches.

Yes. Brisbane has a large defence supply chain around Enoggera, Amberley and the northern corridor. We test against the Australian Government ISM and Essential Eight, which helps suppliers evidence the security controls that defence programs and primes expect.

Yes, with care. We test the IT systems, remote access and the boundary between corporate and OT networks, and our operational technology security team can extend into OT using passive, non-disruptive methods agreed with your engineers.

Often, yes. SMEs are frequent targets, and many now need a pentest to win contracts, answer customer security questionnaires or apply for cyber insurance. A tightly scoped test of your main application keeps the cost manageable.

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.

Black-box testers start with no inside knowledge, like an outside attacker. Grey-box testers get user accounts or limited information, which is the most common and cost-effective option. White-box testers get full documentation or source code for the deepest coverage.

An executive summary, risk-rated findings with evidence, business impact, step-by-step fixes, a debrief and retesting. After retesting we can issue a Letter of Attestation.

security teamPCI DSS requires internal and external testing at least yearly and after significant change. ISO 27001, APRA CPS 234, SOC 2, the SOCI Act and the Australian Government ISM all expect regular security testing as evidence that controls work.
