What Is VAPT?
Vulnerability Assessment & Penetration Testing Explained

94% of organisations that undergo red-team testing face successful penetration. VAPT doesn't just find your vulnerabilities โ€” it proves exactly what an attacker could do with them, so you know which risks to treat first.

VAPT (Vulnerability Assessment and Penetration Testing) is a comprehensive security evaluation that combines automated scanning to discover vulnerabilities with skilled manual testing that simulates real-world cyberattacks โ€” determining not just what weaknesses exist, but what impact an attacker could achieve by exploiting them.

What Is VAPT?

VAPT brings together two distinct but complementary disciplines. The Vulnerability Assessment (VA) phase uses automated tools to systematically identify known security weaknesses across your systems. The Penetration Testing (PT) phase has skilled security professionals manually attempt to exploit those weaknesses โ€” just as a real attacker would โ€” to determine whether they represent a genuine, exploitable risk.

The combination is what makes VAPT so valuable. Automated tools are excellent at breadth โ€” they can check thousands of known vulnerability patterns quickly. Manual testers bring depth โ€” they understand context, chain vulnerabilities together creatively, and uncover logic flaws that no scanner can detect. Together, they provide the most complete picture of your security posture available.

Why It Matters for Your Business

Cybersecurity threats against Australian businesses have escalated significantly. The Australian Cyber Security Centre (ACSC) reported over 94,000 cybercrime reports in the 2022-23 financial year โ€” one every six minutes. The financial impact extends well beyond direct losses: regulatory penalties under the Privacy Act 1988, notifiable data breach obligations, reputational damage, and the cost of recovery all compound the initial harm.

How It Works

A professional VAPT engagement typically follows five phases:

1. Scoping & planning: The engagement scope is defined โ€” which systems, applications, and networks are in scope. Testing type is agreed: black-box (no prior knowledge, simulates external attacker), grey-box (some knowledge, simulates insider threat), or white-box (full access, most thorough).

2. Reconnaissance: Information about the target is gathered from publicly available sources โ€” domain records, exposed services, technology stack, employee information. This mirrors how a real attacker would begin.

3. Vulnerability scanning: Automated tools systematically probe the target for known vulnerabilities, misconfigurations, outdated software, and weak configurations. Common tools include Nessus, Burp Suite, Nikto, and OWASP ZAP.

4. Manual exploitation: Skilled testers attempt to exploit discovered vulnerabilities to determine their real-world impact. This includes testing for OWASP Top 10 vulnerabilities: SQL injection, cross-site scripting (XSS), broken authentication, insecure direct object references, and more.

5. Reporting: A comprehensive report documents every finding with severity ratings, proof-of-concept evidence, business impact assessment, and specific remediation guidance.

Key insight: A vulnerability scanner finding "SQL injection possible" is very different from a penetration tester proving "we extracted your entire customer database using SQL injection in under 10 minutes." VAPT provides the evidence organisations need to prioritise remediation and justify security investment to leadership.

Common Problems Businesses Face

Benefits of Getting This Right

A well-executed VAPT gives leadership a clear, evidence-based picture of real security risk โ€” not theoretical risk. The report tells you what an attacker could actually achieve, how long it would take, and what to fix first. This transforms security from a vague concern into a manageable, prioritised programme.

Beyond the direct security benefit, a completed VAPT report is a valuable business asset. It supports compliance requirements, strengthens relationships with enterprise clients who require security assurance from suppliers, and supports cyber insurance applications. It's evidence that your business takes security seriously in a demonstrable, verifiable way.

How rabbiico Can Help

rabbiico's VAPT service combines automated vulnerability scanning with manual penetration testing conducted by certified security professionals. We test web applications, APIs, and external-facing infrastructure, covering the full OWASP Top 10 and beyond.

Every engagement includes a detailed report with CVSS severity scores, proof-of-concept evidence for critical findings, a prioritised remediation roadmap, and an executive summary suitable for leadership review. We also offer a verification retest after remediation to confirm fixes are effective.

Frequently Asked Questions

Depending on scope, a web application VAPT typically takes 3โ€“10 business days. Larger engagements covering APIs, mobile applications, and network infrastructure can take 2โ€“4 weeks. A detailed scoping conversation before the engagement allows us to estimate accurately based on your specific environment.
A professional VAPT report includes: an executive summary for non-technical stakeholders, a complete vulnerability list with CVSS severity scores (Critical/High/Medium/Low/Informational), proof-of-concept evidence for each exploited vulnerability, business impact assessment, specific remediation steps for each finding, and a risk-prioritised remediation roadmap.
PCI-DSS (required if you process card payments) mandates annual penetration testing and testing after significant infrastructure changes. ISO 27001 strongly recommends it as part of a mature security programme. Australian Privacy Act compliance doesn't explicitly require VAPT, but regulators expect businesses to take reasonable security measures โ€” and VAPT is widely accepted as evidence of due diligence.
We discuss the risk of service disruption during scoping and agree on safe testing windows. For production systems, we can conduct testing in stages or during low-traffic periods. Some vulnerability testing (such as denial-of-service testing) is performed in staging environments only. Our goal is to find vulnerabilities, not create new problems โ€” we take every precaution to minimise operational risk.
Black-box testing simulates an external attacker with no prior knowledge โ€” the tester begins with only the target's URL or IP. Grey-box provides partial information (like a logged-in user account) simulating an insider threat or compromised account scenario. White-box provides full access to source code, architecture diagrams, and credentials โ€” enabling the most thorough assessment. Most web application VAPTs use grey-box methodology for the best balance of realism and thoroughness.
