Vulnerability Assessment and Penetration Testing (VAPT) is a comprehensive security testing methodology that identifies, analyses, and helps remediate security vulnerabilities in your IT infrastructure. This dual-approach security assessment combines systematic vulnerability identification with real-world exploitation attempts to provide a complete view of your security posture.
The Two Core Components of VAPT
Vulnerability Assessment: A systematic review of security weaknesses in your information systems. This process involves scanning and identifying potential vulnerabilities that could be exploited by malicious actors.
Penetration Testing: An authorised simulated attack that exploits identified vulnerabilities to determine whether unauthorised access or other malicious activities are possible in real-world scenarios.
When combined, these methodologies create a powerful security testing framework that helps organisations identify and address security weaknesses before malicious actors can exploit them.

Vulnerability Assessment vs. Penetration Testing: Understanding the Difference
While often used interchangeably, vulnerability assessment and penetration testing serve distinct but complementary purposes:
| Vulnerability Assessment | Penetration Testing |
|---|---|
| Identifies and catalogues potential vulnerabilities | Actively exploits vulnerabilities to demonstrate impact |
| Primarily uses automated scanning tools | Combines automated tools with manual testing techniques |
| Provides broader coverage of the environment | Focuses on depth rather than breadth |
| Typically less intrusive | May involve more aggressive testing techniques |
| Identifies “what could go wrong” | Demonstrates “what happens when things go wrong” |
| Generally faster and less expensive | More resource-intensive and specialised |
| Recommended quarterly or after significant changes | Typically performed annually or semi-annually |
Organisations often begin with vulnerability assessments to identify and address basic security issues before moving on to more comprehensive penetration testing.
When Should You Conduct VAPT?
VAPT should be conducted at strategic times to maximise its effectiveness:
- After Significant Infrastructure Changes: When deploying new systems or making major configuration changes
- Before Product Launches: Prior to releasing new applications or services
- Periodically as Part of Security Governance: Regular testing schedule (quarterly or bi-annually)
- Following Security Incidents: To identify additional vulnerabilities after a breach
- During Compliance Audits: To meet regulatory requirements like PCI DSS, ISO 27001, or GDPR
- Before Company Mergers or Acquisitions: To assess security posture as part of due diligence
The frequency of testing should be determined by your risk profile, industry regulations, and the sensitivity of your data.
Common VAPT Findings and Their Implications
Our VAPT assessments frequently identify these critical vulnerabilities:
Missing Security Patches
Unpatched systems remain one of the most common entry points for attackers. Regular vulnerability assessments help identify missing patches across your infrastructure.
Weak Authentication Mechanisms
Many breaches stem from inadequate authentication controls, including weak passwords, lack of multi-factor authentication, and poor session management.
Insecure Configurations
Default or poorly configured systems often contain security gaps that can be easily exploited. These include default credentials, unnecessary services, and overly permissive access rights.
Input Validation Flaws
Applications that fail to properly validate user input remain vulnerable to injection attacks, including SQL injection, cross-site scripting, and command injection.
Access Control Issues
Inadequate access restrictions can allow users to access resources or perform actions beyond their authorisation level, potentially leading to data breaches or privilege escalation.
How to Prepare for a VAPT Assessment
To maximise the value of your VAPT engagement:
- Define Clear Objectives: Establish what you want to achieve with the assessment
- Document Your Environment: Provide network diagrams and system inventories
- Identify Critical Assets: Highlight your most valuable systems and data
- Designate Points of Contact: Assign technical contacts for testing coordination
- Plan for Downtime Contingencies: Be prepared for potential service disruptions
- Review Legal Considerations: Ensure testing authorisation is properly documented
- Prepare Your Team: Notify relevant personnel about the upcoming assessment
Proper preparation ensures that the assessment proceeds smoothly and delivers actionable results.

FAQ About Vulnerability Assessment and Penetration Testing
What Is the Difference Between a Vulnerability Scan and a Penetration Test?
A vulnerability scan uses automated tools to identify potential security weaknesses, while a penetration test involves active exploitation attempts by security professionals to demonstrate the real-world impact of vulnerabilities. Vulnerability scans are broader but less in-depth, while penetration tests provide deeper insights into specific security issues.
How Often Should We Conduct VAPT?
Most organisations should conduct vulnerability assessments quarterly and penetration tests annually or semi-annually. However, this frequency should be adjusted based on your organisation’s risk profile, regulatory requirements, and rate of infrastructure changes. Critical systems may require more frequent testing.
Will VAPT Disrupt Our Business Operations?
While we take precautions to minimise disruptions, some penetration testing activities carry inherent risks. Our team works closely with your IT staff to schedule testing during appropriate windows and implements safeguards to prevent significant service disruptions. For critical systems, testing can be conducted in staging environments first.
How Do We Address the Vulnerabilities Identified in the VAPT Report?
After receiving your VAPT report, prioritise remediation efforts based on risk ratings and business impact. Address critical and high-risk vulnerabilities immediately, while planning for medium and low-risk issues in your regular maintenance cycles. Our team can provide guidance on effective remediation strategies and validate fixes through retesting.
Is VAPT a Compliance Requirement?
Many regulatory frameworks require some form of security testing, including PCI DSS, HIPAA, GDPR, and ISO 27001. VAPT helps meet these requirements by demonstrating due diligence in identifying and addressing security vulnerabilities. However, specific testing requirements vary by framework.
Can VAPT Guarantee We Won’t Be Breached?
No security testing can provide absolute guarantees against breaches. VAPT significantly reduces your risk by identifying and helping remediate vulnerabilities before they can be exploited. However, security is a continuous process requiring ongoing vigilance, as new vulnerabilities emerge regularly and threat landscapes evolve.
What Credentials Should We Provide for Testing?
This depends on the testing approach. Black-box testing requires no credentials to simulate an external attacker with no prior knowledge. Grey-box testing utilises limited access credentials to simulate insider threats or semi-privileged attackers. White-box testing uses administrative credentials to conduct thorough security assessments of internal components.
