How much should Australian businesses expect to pay for penetration testing?
Penetration testing in Australia typically ranges from a few thousand dollars for a small, tightly scoped web application assessment to tens of thousands for a large, multi-target engagement. The final cost depends on the scope, testing methodology, environment complexity, reporting requirements and whether remediation testing is included, rather than a fixed industry price.
For many organisations, penetration testing is no longer something performed only to satisfy compliance requirements. It has become a practical way to validate security controls, identify exploitable weaknesses and reduce cyber risk before attackers do.
One of the most common questions security leaders ask is, “How much does a penetration test cost in Australia?”
The answer is rarely straightforward. Unlike purchasing software licences or hardware, penetration testing is a professional security assessment tailored to the organisation’s environment, objectives and risk profile. Two organisations requesting a “web application penetration test” may receive vastly different proposals because the applications, infrastructure and security requirements differ significantly.
Understanding what influences pricing helps organisations budget appropriately and compare providers based on value rather than cost alone.
What Drives Penetration Testing Cost?
Scope
Scope is the biggest pricing factor. Testing a single web application differs substantially from assessing multiple internet-facing applications, cloud environments, APIs, internal networks and wireless infrastructure. The greater the number of assets, user roles and attack paths, the more time security consultants require to perform comprehensive testing.
Test Type
Different assessments require different skills. For example, a mobile application penetration test involves analysing mobile-specific functionality, while an API assessment focuses on authentication, authorisation and business logic. Red team engagements require significantly more planning and manual effort than traditional penetration tests.
Depth of Testing
Not every penetration test provides the same level of assurance. Some assessments validate only publicly accessible vulnerabilities, while others include authenticated testing, privilege escalation, lateral movement, business logic testing and manual exploitation techniques. More comprehensive engagements naturally require more time.
Retesting
Many organisations request a second assessment after remediation. Including a retest within the engagement provides assurance that identified vulnerabilities have been effectively addressed.
Compliance Requirements
Some assessments are designed to support regulatory or industry obligations. Testing aligned with PCI DSS, ISO/IEC 27001, APRA CPS 234 or government security frameworks often requires additional documentation, reporting and evidence, which can influence the overall engagement.
Typical Penetration Testing Cost by Test Type
Although every engagement is different, the following ranges provide a useful guide for Australian organisations.
Assessment Type | Typical Australian Price Range (AUD)* |
Small web application | AUD $3,000–$6,000 |
Large or complex web application | AUD $7,000–$15,000 |
External network | AUD $3,000–$10,000 |
Internal network | AUD $5,000–$15,000 |
API penetration test | AUD $4,000–$12,000 |
Mobile applications | AUD $6,000–$15,000 |
Cloud security assessment | AUD $6,000–$20,000 |
Red team engagement | AUD $15,000–$100,000+ |
*These figures are indicative only*
The final price depends on scope, complexity, objectives and reporting requirements rather than the assessment category alone.
What Information Should You Have Before Requesting a Quote?
Providing clear information at the beginning helps ensure your proposal accurately reflects the work required. Most providers will ask questions such as:
- How many applications require testing?
- How many external IP addresses are in scope?
- Is authenticated testing required?
- Are APIs included?
- Will testing occur against production or staging systems?
- Are cloud services included?
- Are mobile applications part of the assessment?
- Are there compliance requirements such as PCI DSS or ISO 27001?
- Will a remediation retest be required?
A clearly defined scope reduces unexpected costs and ensures both parties understand what will and will not be tested.
Why the Cheapest Quote Is Often the Most Expensive
Price should never be the only consideration. A significantly cheaper proposal may indicate that important activities have been excluded. Common limitations include:
- Automated vulnerability scanning instead of manual testing
- No authenticated assessment
- Limited business logic testing
- No privilege escalation testing
- No remediation retest
- Generic reporting with limited remediation guidance
While these engagements may appear attractive initially, they often leave organisations with unanswered questions about their actual security posture. A quality penetration test should demonstrate whether vulnerabilities are genuinely exploitable, not simply identify software versions or missing patches.
What a Quality Penetration Testing Engagement Includes
Organisations should expect far more than a vulnerability list. A professional engagement typically includes:
- Clearly documented scope and assumptions
- Manual security testing performed by experienced consultants
- Validation of exploitability
- Business logic assessment where applicable
- Executive summary suitable for leadership teams
- Detailed technical findings
- Risk-based prioritisation
- Practical remediation recommendations
- Evidence supporting each finding
- Optional remediation retest
Many Australian organisations also look for providers with CREST-certified security professionals, particularly where regulatory expectations or higher assurance testing is required.
How Australian Standards Influence Scope
Security standards do not always mandate penetration testing directly, but they frequently expect organisations to validate security controls through appropriate assurance activities. For example:
- The ACSC Essential Eight encourages organisations to strengthen resilience through layered security controls and ongoing validation.
- PCI DSS requires penetration testing in specific circumstances for organisations handling payment card data.
- APRA CPS 234 expects regulated entities to maintain information security capabilities proportionate to their risks, including regular testing of controls.
- ISO/IEC 27001 supports ongoing security assurance through periodic technical assessments and continual improvement.
As compliance obligations increase, organisations often require broader testing scopes and more comprehensive reporting, which can influence pricing.
How to Compare Penetration Testing Quotes Properly
Comparing proposals solely on price rarely delivers the best outcome. Instead, consider whether each provider clearly explains:
- The systems included within scope
- Testing methodology
- Manual versus automated testing
- Assumptions and exclusions
- Deliverables
- Reporting format
- Whether remediation testing is included
- Expected project duration
- Experience of the testing team
Requesting a sample report can also help assess the quality of communication. A well-written report should provide clear executive summaries alongside technical remediation guidance that security and IT teams can immediately action.
Choosing Value Over Price
Penetration testing should be viewed as an investment in reducing cyber risk rather than simply another compliance expense. A comprehensive assessment may identify weaknesses that could otherwise result in ransomware, data breaches or prolonged business disruption. Choosing a provider based solely on the lowest price can ultimately cost more if important attack paths remain undiscovered or remediation advice lacks sufficient detail.
The best engagements combine technical expertise, realistic attack simulation and actionable reporting that supports both technical teams and executive decision-makers.

Frequently Asked Questions
How much does a penetration test cost in Australia?
Penetration testing costs vary depending on the engagement. Small, tightly scoped assessments typically start in the low thousands of dollars, while larger multi-system or red team engagements can reach tens of thousands. Scope, complexity, reporting requirements and remediation testing all influence the final price.
How much does a penetration test cost in Australia?
Penetration testing costs in Australia typically range from AUD $3,000 to more than AUD $100,000, depending on the type of assessment, scope, number of systems, testing depth and reporting requirements. A small web application assessment will generally cost less than a large internal network or red team engagement.
What makes one penetration test cost more than another?
Several factors affect pricing, including the number of assets in scope, testing depth, authenticated versus unauthenticated testing, compliance requirements, reporting expectations and whether a remediation retest is included. More complex environments generally require additional consultant time and expertise.
Is a cheap penetration test worth it?
Not always. Lower-cost assessments may rely heavily on automated tools, exclude authenticated testing, omit business logic analysis or provide limited remediation guidance. A quality penetration test should validate real-world exploitability and provide practical recommendations to improve security rather than simply generate a vulnerability list.
Does the Essential Eight require penetration testing?
The ACSC Essential Eight does not explicitly require penetration testing. However, organisations pursuing higher maturity levels or aligning with broader government security expectations often use penetration testing as evidence that security controls have been independently validated and are operating effectively.
Does ISO/IEC 27001 require penetration testing?
ISO/IEC 27001 does not specifically mandate penetration testing for every organisation. However, many certification bodies and auditors expect independent technical testing for higher-risk systems as evidence that security controls are effective. Penetration testing is commonly used to support risk assessments, control validation and continual improvement activities.
Does SOC 2 require penetration testing?
SOC 2 does not explicitly require penetration testing, but it expects organisations to demonstrate that security controls are operating effectively. Independent penetration testing is widely recognised as a strong way to validate technical controls, identify exploitable weaknesses and provide evidence for SOC 2 audits, particularly under the Security Trust Services Criteria.
How long does a penetration test take in Australia?
Most penetration testing engagements take between 5 and 15 business days, depending on the size of the environment, scope, testing depth and reporting requirements. Smaller web application assessments can often be completed within a week, while larger internal network or red team engagements typically require more time.
What’s the difference between a vulnerability scan and a penetration test?
A vulnerability scan is primarily automated and identifies known vulnerabilities across systems. A penetration test goes much further by manually validating exploitability, chaining vulnerabilities together, assessing business logic and demonstrating real-world attack paths. Vulnerability scanning supports ongoing security hygiene, while penetration testing provides a deeper assessment of actual cyber risk.
How often should an organisation conduct a penetration test?
Most Australian organisations perform penetration testing annually or whenever significant changes occur, such as cloud migrations, major application releases, infrastructure upgrades or mergers. Organisations operating in highly regulated or high-risk environments often perform testing more frequently as part of their ongoing security programme.
What should be included in a good penetration test report?
A quality penetration test report should include an executive summary for management, detailed technical findings, evidence supporting each vulnerability, business impact, risk ratings, reproducible steps and prioritised remediation guidance. The report should be practical enough for technical teams while also supporting governance and compliance reporting.
What’s the difference between internal and external penetration testing?
External penetration testing simulates an attacker attempting to compromise publicly accessible systems from the internet. Internal penetration testing assumes an attacker has already gained a foothold within the network, such as through a compromised workstation or insider access. Most organisations benefit from performing both types of assessments.
Is CREST certification important when choosing a penetration testing provider in Australia?
Yes. Choosing a CREST-certified provider provides confidence that testing is performed using recognised methodologies by qualified security professionals who meet independent competency and quality standards. Many government agencies and enterprise organisations either require or strongly prefer CREST-certified providers.
Can penetration testing help with Essential Eight maturity?
Although penetration testing is not formally required by the Essential Eight, it is commonly used to demonstrate that security controls are functioning as intended. Independent testing can validate controls relating to application control, patch management, multi-factor authentication and administrative privilege restrictions, providing stronger evidence of security maturity.
What types of systems can be included in a penetration test?
Penetration testing can cover a wide range of systems, including external and internal networks, web applications, mobile applications, APIs, cloud platforms such as Microsoft Azure and AWS, wireless networks and, where appropriate, operational technology (OT) or industrial control systems. The final scope is agreed before testing begins.
Do you offer remediation retesting?
Most reputable penetration testing providers either include remediation retesting or offer it as an optional service. Retesting confirms that identified vulnerabilities have been successfully remediated and provides organisations with confidence that security improvements have been effectively implemented.
