VAPT combines two complementary practices: a vulnerability assessment to identify known weaknesses at scale and a penetration test to safely exploit and validate real-world impact. Together, they give teams a prioritized view of risk and help prove which findings truly matter. VAPT in AppSec: Where It Fits VAPT is typically performed against running systems, apps, APIs, and infrastructure to validate security controls and quantify exploitability. In modern software delivery, it works best alongside shift-left testing methods like SAST, SCA, and runtime testing with DAST. A combined approach helps teams find issues early (SAST/SCA), observe behavior in a running app (DAST), and then validate the most critical paths via VAPT. To go deeper on these methods, see our SAST vs. DAST comparison and the SAST Knowledge Hub and DAST Knowledge Hub. Vulnerability Assessment vs. Penetration Testing (VA vs. PT) Vulnerability Assessment (VA) uses automated scanners and known vulnerability data to inventory and prioritize weaknesses across assets. Penetration Testing (PT) applies manual, adversary-like techniques to exploit selected weaknesses, demonstrate impact, and validate what is truly exploitable in context. Quick comparison: – Primary purpose: VA identifies known weaknesses at scale; PT validates exploitability and real-world impact. – Typical approach: VA relies on automated scanning and configuration checks; PT uses manual testing and controlled exploitation by experts. – Coverage vs. depth: VA offers broad coverage and may include false positives; PT goes deeper on critical paths with fewer false positives. – Output: VA produces a ranked list of vulnerabilities with severity; PT provides evidence-backed findings, exploit paths, and risk scenarios. – Best use: VA for routine visibility and hygiene; PT for assurance, control validation, and compliance testing.

VAPT Process: From Scoping to Retesting 1) Scoping & rules of engagement: Define in-scope apps, APIs, environments, timelines, success criteria, and legal permissions. 2) Discovery & enumeration: Map assets, tech stacks, and attack surface (hosts, services, endpoints). 3) Vulnerability assessment: Run authenticated/unauthenticated scans and configuration checks; enrich with threat intelligence. 4) Exploitation & post-exploitation (PT): Attempt safe exploitation of priority findings; chain issues to show business impact. 5) Risk analysis & reporting: Document evidence, likelihood/impact, affected components, and remediation guidance. 6) Fix & retest: Remediate, verify fixes, and update residual risk.

Checklist: What a VAPT Report Should Include Executive summary with risk narrative and top findings Detailed technical findings with evidence (requests/responses, PoC where appropriate) Exploit paths, affected assets, and business impact Clear remediation and mitigation guidance (prioritized) Methodology, scope, tools, and tester qualifications Retesting results and closure status How Often to Run VAPT (and What Compliance Expects) Run assessments and tests on a regular cadence and after significant changes. Many public-sector and enterprise guidelines emphasize performing both activities throughout delivery—not as a one-off pre-release gate. Tip: Use continuous scanning to maintain visibility and schedule targeted PT to validate your most critical apps and new attack paths. For payment card environments, penetration testing expectations sit under PCI DSS Requirement 11 (segmentation validation included); organizations targeting ISO/IEC 27001 should apply testing as part of risk-based control validation and continuous improvement. Explore dynamic testing options with Checkmarx DAST, then complement with developer-first prevention using SAST and SCA. VAPT FAQs Is VAPT the same as vulnerability scanning? No. Scanning identifies potential issues at scale; a penetration test validates exploitability and impact. Use both. Where does VAPT fit in DevSecOps? Shift left with SAST and SCA to prevent defects in code and dependencies, apply DAST for runtime coverage, and use VAPT to validate what really matters before (and after) release. What’s the deliverable? An evidence‑based report with prioritized findings, exploit paths, and actionable fixes – plus retest results confirming remediation.
