Penetration Testing Brisbane

CRT Network Solutions provides penetration testing for Brisbane businesses that want an independent, structured test of their real-world security posture. We simulate the same techniques attackers use against Australian businesses (identity attacks, phishing, exposed services, unpatched vulnerabilities) and hand you a written report with the exact findings, the exact fix, and a prioritised remediation plan.

What Our Brisbane Penetration Testing Includes

Every engagement follows a defined scope agreed in writing before we start. What’s included in the standard scope:

Reconnaissance and information gathering

What can be discovered about your business from public sources before an attack starts.

External network testing

Perimeter systems (firewalls, VPNs, remote access, exposed services) tested for exploitable weaknesses.

Internal network testing

If in scope, simulated attacks from inside the network (representing a compromised laptop, a rogue insider, or a physical intruder).

Identity and access testing

Attacks against your Microsoft 365 or Google Workspace identity system, including phishing, credential stuffing, and privilege escalation.

Detailed written report

Executive summary for leadership, technical findings for IT, prioritised remediation roadmap, and evidence for auditors or insurers.

Debrief and remediation call

We walk your team through the findings and answer questions before you commit to any fixes.

Types of Penetration Testing We Offer

Not every business needs the same test. We scope each engagement based on your environment, risk profile, and budget.

External network pentest

Focuses on what’s exposed to the internet. Suitable for businesses that want to know what an outside attacker can reach.

Internal network pentest

Simulates a threat already inside (compromised laptop, phishing victim, insider). Answers: “What happens after the first bad click?”

Microsoft 365 tenant pentest

Tests your M365 environment specifically. Identity, conditional access, sharing, permissions, and OAuth app abuse.

Why Brisbane Businesses Need Penetration Testing

Penetration testing used to be something only large enterprises and government departments commissioned. That’s changed. Three factors have pushed it firmly into the Australian SME market.

Cyber insurance underwriters now expect it.

Most Australian cyber insurance providers renewing policies in 2026 ask for evidence of independent security testing within the last 12 to 24 months. Without it, premiums increase, or cover is refused.

Client and contract requirements are pushing it down the supply chain.

Government tenders, enterprise procurement, and increasingly professional services engagements now include security testing clauses. If you supply anyone larger than you, they're starting to ask.

The threat landscape justifies it on its own merits.

According to the ACSC Annual Cyber Threat Report 2024-25, medium businesses lost an average of $97,166 per cyber incident last year. A single competent pentest costs a fraction of that and, in most cases, prevents it.

Brisbane businesses in professional services (legal, medical, accounting, engineering), managed service providers, and any business with intellectual property or sensitive client data are the most common candidates.

Who Needs a Brisbane Pentest

Penetration testing is a good investment for Brisbane businesses that meet any of the following:

Renewing cyber insurance and want to secure better premiums or meet the underwriter’s evidence requirements.
Bidding on government or enterprise contracts where security testing is a tender requirement.
Handling regulated data (medical, legal, financial) and needing to demonstrate due diligence for RACGP, LPCC, or APRA CPS 234 obligations.
After a significant IT change (M365 rollout, new web application, office move, MSP change) and wanting independent confirmation the new setup is secure.
Before a suspected incident escalates, or after one, to identify the gaps that let it happen.
Any Brisbane business that hasn’t had a pentest in the last 12 months and wants to know where they actually stand.

How Our Brisbane Penetration Testing Process Works

A pentest is a defined engagement, not an open-ended project. Every one of ours runs on the same five-stage process.

1. Scoping and rules of engagement

We meet with you (in person in Brisbane or remote), understand your environment, agree on scope, and put rules of engagement in writing.

2. Reconnaissance and testing

We conduct the test, once or multiple times, over an agreed window. You have a named contact you can reach at any time during the test.

3. Reporting

You receive a written report with an executive summary, technical detail, evidence, and a prioritised remediation roadmap.

4. Debrief

A working session with your IT team, your MSP, or your executive to walk through the findings and answer questions.

5. Remediation plan

We supply you with a remediation plan and an optional quote for us to carry out the remediation.

The Questions Our Team Get Asked

Frequently Asked Questions

How often should a Brisbane business do penetration testing?

The standard cadence is every 12 to 24 months, with an additional test after any material change to your environment (new web application, M365 rollout, office move, MSP change). Some regulated industries or government contracts require annual testing.

How long does a penetration test take?

Testing itself typically runs 5 to 15 business days depending on scope. From first scoping call to final report, most Brisbane pentests take 3 to 6 weeks.

Will a penetration test disrupt our business?

No. Every test is conducted under agreed rules of engagement, with defined windows and defined limits. We don't run destructive tests during business hours, we don't test production systems without written approval, and we have a named contact who can pause the test if anything unexpected happens. Disruption is not part of a properly-scoped pentest.

Do you provide a report we can share with our cyber insurance provider?

Yes. The written report is designed to be shared with cyber insurance underwriters, auditors, and enterprise clients requesting evidence of security testing. It includes an executive summary suitable for non-technical readers and a technical detail section for your IT team or MSP.

Do we need to be a CRT managed IT client to book a pentest?

No. Brisbane penetration testing is available to any business, whether or not you're an existing CRT client. Many of our pentest clients have an in-house IT team or a different MSP. We just deliver the test.

What happens if you find something serious during the test?

If we discover an active compromise or a critical vulnerability being actively exploited, we contact you immediately (before the report is written) so you can act. This is defined in the rules of engagement before the test starts, so there's no ambiguity if it happens.
