According to the Australian Cyber Security Centre's Annual Cyber Threat Report (2025), 62% of Australian SMBs experienced a cyber incident in the previous 12 months, with average remediation costs exceeding $50,000 for serious incidents [1].
One-Time Security Assessment Costs
How Much Does a Security Assessment Cost?
A professional security assessment for Australian SMBs typically costs between $1,500 and $5,000 for a baseline evaluation, with comprehensive assessments ranging from $5,000 to $15,000 depending on scope and complexity. These assessments identify vulnerabilities, map your attack surface, and provide prioritised remediation roadmaps.
According to lilMONSTER's 2026 pricing research, security assessments for Australian SMBs typically fall into three tiers:
| Assessment Type | Cost Range | What's Included | Best For |
|---|---|---|---|
| Baseline Scan | $1,500-$2,500 | Asset inventory, external exposure scan, vulnerability assessment, credential leak check, prioritised roadmap | First-time assessments, businesses "knowing they need to do something" |
| Comprehensive Assessment | $5,000-$8,000 | Everything in baseline plus ISO 27001 gap analysis, incident response plan review, policy gap analysis, tabletop exercise | Growing SMBs preparing for compliance or enterprise customers |
| Full Security Audit | $8,000-$15,000 | All above plus internal penetration testing, detailed control mapping, compliance evidence review, executive and technical reports | Organisations with compliance requirements or recent incidents |
What Factors Affect Security Assessment Costs?
Several factors influence the final cost of a security assessment:
- Organisation size: Employee count, number of systems, and complexity of the IT environment directly impact assessment scope.
- Cloud footprint: Multi-cloud environments (AWS, Azure, Google Cloud, SaaS applications) require broader assessment coverage.
- Compliance requirements: Assessments aligned with ISO 27001, Essential Eight, or industry-specific frameworks require additional analysis.
- Remote work infrastructure: VPN configurations, remote access systems, and BYOD policies add assessment complexity.
- Industry-specific risks: Healthcare, financial services, and government contractors face higher scrutiny and require deeper assessments.
Penetration Testing Costs
How Much Does Penetration Testing Cost for SMBs?
Penetration testing for Australian SMBs typically costs between $5,000 and $15,000 for initial assessments, according to lilMONSTER's 2026 pricing research. The final cost depends on scope, testing type, and the complexity of systems being tested.
Penetration testing is an authorised simulated attack on your systems to identify exploitable vulnerabilities. Unlike vulnerability assessments (which identify potential weaknesses), penetration tests actively attempt to breach your defences using the same techniques real attackers employ.
Penetration Testing Cost Breakdown by Type
| Test Type | Cost Range | Scope | Timeline |
|---|---|---|---|
| External Network Test | $5,000-$10,000 | Internet-facing systems, web applications, VPN gateways | 1-2 weeks |
| Internal Network Test | $7,000-$15,000 | Internal infrastructure, Active Directory, internal applications | 2-3 weeks |

| Mobile Application Test | $5,000-$10,000 | iOS and Android applications | 2-3 weeks |
| Social Engineering Test | $3,000-$8,000 | Phishing campaigns, vishing, physical security tests | 1-2 weeks |
| Full Red Team Engagement | $15,000-$50,000+ | Comprehensive adversarial simulation across all attack vectors | 4-8 weeks |
What Determines Penetration Testing Cost?
According to the Australian Cyber Security Centre (2025), organisations that conduct regular penetration testing identify critical vulnerabilities 3x faster than those relying solely on automated scanning [2]. The cost factors include:
- Target scope: Number of IP addresses, applications, and systems in scope
- Testing depth: Black box (no insider knowledge) vs. grey box (partial knowledge) vs. white box (full knowledge)
- Complexity: Custom applications, legacy systems, and unusual architectures require more testing time
- Reporting requirements: Executive summaries, detailed technical findings, and remediation guidance
- Retesting: Validation testing after fixes are implemented (typically 20-30% of initial test cost)
vCISO Services Pricing
How Much Does a vCISO Cost?
Virtual Chief Information Security Officer (vCISO) services for Australian SMBs typically cost between $2,000 and $6,000 per month, according to lilMONSTER's 2026 pricing research. vCISO services provide strategic security leadership without the cost of a full-time executive hire.
A vCISO is an outsourced security executive who provides strategic guidance, manages security programs, liaises with boards and executives, and ensures your security investments align with business objectives. For SMBs that cannot justify a $200,000-$350,000 annual salary for a full-time CISO, vCISO services deliver comparable expertise at a fraction of the cost.
vCISO Pricing Tiers
| Service Level | Monthly Cost | Included Services | Best For |
|---|---|---|---|
| Advisory vCISO | $2,000-$3,500 | Monthly strategy calls, policy review, compliance guidance, vendor assessment support | SMBs with existing IT teams needing strategic direction |
| Program vCISO | $3,500-$5,000 | Everything in Advisory plus security program management, board reporting, incident response coordination, team mentoring | Growing SMBs building formal security programs |
| Executive vCISO | $5,000-$8,000+ | Full CISO responsibilities including board presentation, regulatory liaison, M&A security due diligence, 24/7 escalation | Mid-market companies, regulated industries, pre-IPO companies |
What Does a vCISO Actually Do?
According to Gartner's research on security leadership (2025), organisations with dedicated security leadership experience 43% fewer security incidents than those without [3]. A vCISO typically provides:
- Strategic planning: Security roadmap development aligned with business objectives
- Board and executive reporting: Translating technical risk into business language for leadership
- Compliance management: Ensuring alignment with Essential Eight, ISO 27001, Privacy Act, and industry regulations
- Vendor management: Evaluating and managing security vendors and tools
- Incident response leadership: Coordinating response to security incidents
- Team development: Mentoring internal IT staff on security best practices
- Budget optimisation: Ensuring security investments deliver maximum risk reduction

Cybersecurity ROI for Australian SMBs
Is Cybersecurity Worth the Investment for Small Businesses?
Cybersecurity investment delivers positive ROI for Australian SMBs when viewed against breach prevention costs. According to IBM's Cost of a Data Breach Report (2025), organisations with mature security programs reduce breach costs by an average of $1.76 million AUD [5].
ROI Calculation Example
Consider an Australian professional services firm with 50 employees:
| Scenario | Annual Cost |
|---|---|
| Security Investment | |
| Annual security assessment | $3,000 |
| Penetration testing (annual) | $8,000 |
| vCISO services | $36,000 ($3,000/month) |
| Managed detection & response | $24,000 ($2,000/month) |
| Security awareness training | $2,000 |
| Total Annual Investment | $73,000 |
| Potential Breach Cost | $150,000-$500,000 |
In this scenario, a single prevented breach pays for 2-7 years of security investment. The ROI improves further when considering:
- Insurance premium reductions: Cyber insurers offer discounts of 10-30% for organisations with mature security programs
- Customer retention: Security credentials help retain customers who require vendor security assessments
- Business development: Security certifications enable enterprise and government contract opportunities
- Operational efficiency: Well-implemented security controls reduce IT overhead and incident response costs
