Short answer
VAPT stands for Vulnerability Assessment and Penetration Testing. It is a two-part security test: a vulnerability assessment scans systems to find and rank known weaknesses, and a penetration test has certified ethical hackers safely exploit those weaknesses to prove real business impact. Together they show what is vulnerable and what an attacker could actually do.
What does VAPT stand for?
VAPT is the combination of two complementary activities. The vulnerability assessment (VA) is broad and largely automated: it inventories assets and flags missing patches, misconfigurations and known CVEs. The penetration test (PT) is deep and manual: a tester chains weaknesses together, exploits them in a controlled way, and demonstrates impact such as data access or privilege escalation.
Why is VAPT important?
Attackers increasingly get in through unpatched or misconfigured systems. The Verizon 2025 Data Breach Investigations Report found that exploitation of vulnerabilities was the initial access vector in 20% of breaches, up 34% on the previous year, and IBM put the global average cost of a breach at US$4.44 million in 2025.
VAPT finds those weaknesses first, gives you prioritised fixes, and produces independent evidence that customers, auditors and regulators ask for under PCI DSS, SOC 2, ISO 27001, HIPAA, GDPR, NIST and CMMC.
What are the types of VAPT?
- Web application VAPT: websites, portals and SaaS apps tested against the OWASP Top 10.
- Mobile application VAPT: Android and iOS apps tested against OWASP MASVS.
- API VAPT: REST, GraphQL and SOAP APIs tested against the OWASP API Security Top 10.
- Network VAPT: internal and external networks, servers, firewalls and Active Directory.
- Cloud VAPT: AWS, Azure and GCP configuration and identity attack paths.
- Wireless, IoT and OT VAPT: Wi-Fi, connected devices and industrial systems.
What are the benefits of VAPT?
- Find real risk first: verified, exploitable issues ranked by CVSS and business impact.
- Meet compliance: evidence for PCI DSS 11.4, ISO 27001 Annex A 8.8 and SOC 2.
- Win customer trust: a third-party report answers enterprise security questionnaires.
- Reduce breach cost: fixing issues before exploitation is far cheaper than incident response.
How does the VAPT process work?
- 1ScopingAgree targets, test type (black, grey or white box), timelines and rules of engagement.
- 2ReconnaissanceMap the attack surface: hosts, URLs, APIs, roles and technologies.
- 3Vulnerability assessmentRun tuned scans and manual checks to identify candidate weaknesses.
- 4Penetration testingSafely exploit weaknesses to confirm them and measure impact.
- 5ReportingDeliver an executive summary and technical findings with CVSS scores and fixes.
