VAPT (Vulnerability Assessment & Penetration Testing) combines automated scanning with manual exploitation to identify and validate security weaknesses before attackers do. This guide covers methodologies, tools, pricing, compliance requirements, and how to choose the right provider.

VAPT is a comprehensive security testing methodology that combines two complementary approaches: Vulnerability Assessment (automated identification of known weaknesses) and Penetration Testing (manual exploitation to validate real-world attack paths). Together, they provide a complete picture of an organisation's security posture.
According to Verizon's 2025 DBIR, 68% of breaches involved a human element or unpatched vulnerability. Regular VAPT assessments are the most effective way to identify these weaknesses before they're exploited.

Penetration testing comes in several flavours, each suited to different objectives: Black Box (simulates external attacker), White Box (full access for deep analysis), and Grey Box (partial knowledge, simulating an insider threat or compromised account).
Additionally, testing can target specific surfaces: web applications (aligned with OWASP Top 10), mobile apps, network infrastructure, cloud environments, and APIs. A comprehensive VAPT programme covers all critical surfaces annually.
05
Industry-standard methodologies ensure consistent, repeatable results. The Penetration Testing Execution Standard (PTES) defines seven phases: Pre-engagement, Intelligence Gathering, Threat Modeling, Vulnerability Analysis, Exploitation, Post-Exploitation, and Reporting.
For web applications, the OWASP Testing Guide v4 provides a comprehensive checklist covering authentication, authorisation, session management, input validation, and business logic testing.
06
Professional VAPT engagements leverage a mix of commercial and open-source tools. Key tools include Nessus and Qualys for vulnerability scanning, Burp Suite Professional for web app testing, Metasploit for exploitation, and Nmap for network discovery.
07
VAPT directly supports compliance with multiple frameworks. PCI DSS (Requirement 11) mandates quarterly scans and annual pen tests. ISO 27001 Annex A.12.6 requires vulnerability management. RBI's cybersecurity framework mandates periodic VAPT for all regulated entities. Our compliance services help map VAPT findings to specific control requirements.
08
VAPT pricing depends on scope, methodology, and compliance needs. Typical pricing for the Indian market ranges from ₹1.5 lakh for a single web application to ₹20+ lakh for comprehensive enterprise assessments. Tatva Networks offers transparent, scope-based pricing - request a custom quote.

Look for providers with CERT-In empanelment or alignment, experienced certified testers (OSCP, CEH, GPEN), industry-specific experience, and clear reporting that includes business impact assessment - not just a vulnerability dump. Tatva Networks is ISO 27001 certified, bringing 18+ years of enterprise VAPT experience across BFSI, government, and critical infrastructure.

VAPT is not a one-time checkbox - it's an ongoing programme that evolves with your attack surface. By combining regular assessments with continuous monitoring through a managed SOC, organisations achieve defence-in-depth that significantly reduces breach risk.

At minimum, annually - but quarterly assessments are recommended for high-risk environments. Regulatory frameworks like PCI DSS mandate quarterly scans and annual penetration tests. After major infrastructure changes, an ad-hoc VAPT is essential.
Black box testing simulates an external attacker with no prior knowledge of the target. White box testing provides the tester with full access to source code, architecture, and credentials - enabling deeper analysis of logic flaws and internal vulnerabilities.
VAPT pricing varies based on scope: web application testing typically ranges from ₹1.5-5 lakh, network VAPT from ₹2-8 lakh, and comprehensive enterprise assessments from ₹5-20 lakh. Factors include asset count, testing depth, and compliance requirements.
Yes, for several frameworks. PCI DSS requires quarterly vulnerability scans and annual penetration tests. ISO 27001 Annex A.12.6 mandates vulnerability management. RBI guidelines for banks and NBFCs require periodic VAPT assessments.
