Common questions about our vulnerability assessment and penetration testing services
Vulnerability Assessment (VA) and Penetration Testing (PT) are complementary but distinct methodologies defined in NIST SP 800-115. VA uses automated scanning tools like Nessus and Qualys to identify and catalog known vulnerabilities (CVEs) across your attack surface. Penetration Testing goes further by simulating real-world adversary tactics - aligned with the MITRE ATT&CK framework - to actively exploit those vulnerabilities and demonstrate business impact. According to the Ponemon Institute, organizations that combine both approaches reduce their mean time to detect (MTTD) breaches by 37%. Our VAPT methodology integrates automated scanning with manual exploitation and logic testing, following OWASP Testing Guide v4.2 and PTES (Penetration Testing Execution Standard) frameworks to deliver actionable, risk-ranked findings.
How long does a VAPT engagement typically take?
A standard VAPT engagement takes 2-4 weeks depending on scope and complexity. Per NIST SP 800-115 guidelines, the engagement lifecycle includes: reconnaissance and scoping (1-2 days), active testing using both automated and manual techniques (1-2 weeks), analysis and CVSS-scored report preparation (3-5 days), and remediation consultation. For large enterprises with 500+ assets or complex multi-cloud environments, engagements may extend to 6-8 weeks. SANS Institute research indicates that organizations conducting quarterly VAPT see a 45% reduction in exploitable vulnerabilities compared to annual-only testing. We also offer continuous VAPT programs with automated re-testing for DevSecOps pipelines.
No - our testing methodology is designed for zero business disruption, following NIST and OWASP guidelines for safe testing practices. We use non-destructive exploitation techniques, coordinate testing windows with your operations team, and maintain real-time communication throughout the engagement. According to SANS research, fewer than 0.1% of professional penetration tests cause unplanned outages when conducted by certified testers. For critical OT/SCADA systems or high-availability environments, we perform testing against isolated replicas or staging environments first. In 17+ years of engagements across BFSI, healthcare, and government sectors, we have maintained a zero-downtime record.
Our security professionals hold industry-leading certifications recognized by NIST and OWASP frameworks. These include OSCP (Offensive Security Certified Professional), CEH (Certified Ethical Hacker), GPEN and GWAPT (GIAC certifications), and vendor-specific cloud security credentials for AWS, Azure, and GCP. Our testers undergo annual competency validation, ensuring they stay current with evolving TTPs (Tactics, Techniques, and Procedures). According to ISC², certified penetration testers identify 28% more critical vulnerabilities than non-certified testers. Our team undergoes continuous training through platforms like Hack The Box and participates in CTF (Capture The Flag) competitions to sharpen offensive skills.
How often should we conduct VAPT assessments?
NIST SP 800-53 recommends risk-based testing frequency: annually at minimum, quarterly for high-risk environments, and after every significant change. Regulatory mandates reinforce this - PCI-DSS requires annual penetration testing and quarterly vulnerability scans, RBI Cybersecurity Framework mandates annual VAPT for all regulated entities, and SEBI CSCRF requires bi-annual assessments for market intermediaries. Verizon's 2024 DBIR found that 60% of breaches exploited vulnerabilities for which patches were available but untested. Organizations with continuous VAPT programs - integrating testing into CI/CD pipelines - reduce their vulnerability remediation time by 72% compared to annual-only testing. We recommend a risk-tiered approach: quarterly for internet-facing assets, semi-annually for internal infrastructure, and continuous for DevSecOps environments.
What do you test during a VAPT engagement?
Our VAPT scope covers the full attack surface as defined by the OWASP Testing Guide and NIST SP 800-115. This includes web applications (OWASP Top 10, business logic flaws), mobile applications (iOS and Android, per OWASP MASTG), external and internal network infrastructure, cloud environments (AWS, Azure, GCP - per CIS Benchmarks), APIs (REST, GraphQL, SOAP - per OWASP API Security Top 10), and IoT/embedded devices. Each assessment is tailored to your technology stack and threat model. We use a combination of commercial tools (Burp Suite Pro, Nessus, Metasploit) and custom scripts for business-logic testing. According to SANS, 35% of critical vulnerabilities are logic flaws that automated scanners miss - our manual testing methodology specifically targets these gaps.
