What VAPT is
Vulnerability assessment and penetration testing is a structured way to find weaknesses and confirm real attack risk. VAPT combines vulnerability discovery with controlled exploitation to prove impact — not just to list issues, but to show which ones an attacker can exploit and how far they could get.
A VAPT audit shows you where you stand, evidences whether your controls actually work, supports compliance, and gives you what you need to make risk decisions from tested evidence rather than assumption.
Why organisations need VAPT
You need VAPT to see your security risk clearly. It finds vulnerabilities, confirms which ones are exploitable, shows whether your controls work, and produces the documented evidence that regulatory audits, client assessments and internal reviews demand.
A VAPT audit helps your teams focus on the issues that matter, reduce risk and cut the blind spots in your security posture. It applies wherever an organisation handles sensitive data or runs critical systems, and matters most in regulated sectors:
- Banking, financial services, fintech and payment processing under regulatory and PCI DSS obligations.
- Healthcare, insurance and life sciences protecting patient and customer data.
- IT, software and cloud providers meeting client and contractual security expectations.
- Government, critical infrastructure, energy and manufacturing safeguarding operational systems.
CyberSigma’s role
We are your independent testing partner. We scope the engagement, run the assessment and controlled exploitation, rate the findings by real impact, and issue the report — with remediation guidance and a retest to confirm the fixes hold.
Independence and empanelment
CyberSigma is a CERT-In empanelled testing provider, and testing is conducted independently of the teams that built and run your systems. That independence is what gives the VAPT report its standing with regulators, customers and auditors.
How we deliver
Our VAPT process follows a structured, repeatable method that finds vulnerabilities, confirms exploitability and produces audit-ready results with controlled testing and minimal disruption.
Scoping and authorisation
We define the scope, objectives, assets and testing depth — including black, grey or white box approach — and confirm legal authorisation before any testing begins.
Reconnaissance
We gather technical detail on the in-scope systems, applications and infrastructure, mapping technologies, exposed services and attack surface the way an attacker would.
Vulnerability assessment
Automated tooling and manual testing surface vulnerabilities, misconfigurations and insecure logic. Validated findings are mapped to affected assets and given an initial severity, cutting false positives.
Exploitation
Confirmed vulnerabilities are exploited under controlled conditions to validate real attack paths, determine achievable access and verify potential compromise of sensitive systems or data.
Post-exploitation analysis
We assess the potential for privilege escalation, lateral movement and the scope of access reachable from each foothold, to establish the true security and business impact.
Reporting and retest
We document validated findings with evidence, impact-and-likelihood risk ratings and remediation guidance, then retest after your fixes to confirm the issues are closed and no new risk has appeared.
What you receive
- A detailed VAPT report with validated findings and supporting evidence
- Impact-and-likelihood risk ratings for every confirmed issue
- Practical, prioritised remediation guidance for each finding
- Separate executive and technical summaries for leadership and engineers
- Documented evidence for regulatory audits, client assessments and internal reviews
- Retest confirmation that remediated vulnerabilities are properly resolved
Indicative timeline
A typical engagement runs from about one to three weeks, depending on the number and complexity of the assets in scope, the testing depth agreed and the maturity of your current controls.
Timelines vary with scope and readiness; we confirm a schedule after scoping.
What we test
We assess vulnerabilities, confirm exploitability and provide audit-ready evidence across the environments that carry your risk:
Application security
Web, mobile, API and thick-client application testing, plus secure source-code review, covering authentication, access control, input validation and business logic.
Network and infrastructure
External and internal network penetration testing, network vulnerability assessment, wireless testing and firewall and device configuration review.
Cloud and platform
Cloud infrastructure penetration testing, cloud configuration and access-control review, and container and Kubernetes security testing.
Advanced simulation
Red team testing, privilege-escalation and lateral-movement testing, and controlled social-engineering exercises to test detection and response.
Representative engagement
A financial-services organisation needed independent assurance across its customer-facing applications and supporting network before a regulatory audit. We scoped the assets, ran the vulnerability assessment and controlled exploitation, validated the exploitable findings, rated them by real business impact, and retested after remediation to confirm closure. Named client references are available under NDA on request.
Who leads your engagement
Your engagement is led by senior penetration testers — supported by application, infrastructure, cloud and network specialists matched to your environment. Every finding passes independent quality review before the report reaches you. We introduce your named lead on the first call.

Frequently asked questions
What makes CyberSigma one of the top VAPT companies in India?
CyberSigma is a CERT-In empanelled VAPT company delivering web, mobile, API, network and cloud penetration testing across India. As a VAPT service provider we combine manual, exploit-driven testing with clear, developer-ready reporting and free retesting — and, as a PCI SSC-listed QSA firm, we align the testing to PCI DSS, RBI, SEBI and CERT-In requirements. Assessment and validation are done in-house, not resold.
How do I choose a VAPT service provider or testing company?
Look for a CERT-In empanelled VAPT testing company that does manual (not just automated) testing, gives proof-of-concept evidence and CVSS ratings, includes a retest to confirm fixes, and can map findings to your regulatory obligation (PCI DSS, RBI, SEBI CSCRF, CERT-In safe-to-host). Ask to see a redacted sample report before you engage.
Why is VAPT important for organisations?
VAPT helps you understand real security risks, validate the effectiveness of controls, prevent breaches and meet regulatory, audit and client security requirements.
How does VAPT differ from a vulnerability scan?
A vulnerability scan only detects known issues. VAPT confirms exploitability through manual testing, providing accurate risk context and reducing false positives.
What is the difference between vulnerability assessment and penetration testing?
Vulnerability assessment identifies weaknesses, while penetration testing exploits selected vulnerabilities to confirm real attack paths and business impact.
How often should an organisation perform a VAPT audit?
VAPT audits should run annually, after significant system changes or application releases, or to meet regulatory and client security requirements.
Is VAPT suitable for all organisations?
Yes. VAPT services are relevant for startups, SMEs and large enterprises handling sensitive data, critical systems or regulated workloads.
What types of vulnerabilities can VAPT uncover?
VAPT can find application flaws, misconfigurations, weak authentication, access control issues, exposed services and exploitable attack paths.
What are Black Box, White Box, and Grey Box testing?
Black Box tests simulate external attackers, White Box uses full system knowledge and Grey Box combines limited access with realistic attack scenarios.
What are the key stages of penetration testing?
Scoping, information gathering, vulnerability identification, exploitation, impact analysis, reporting, remediation guidance and retesting.
Is penetration testing automated or manual?
Effective VAPT uses both automated tools and manual testing. Manual validation is essential for confirming exploitability and minimising false positives.
Will penetration testing impact production systems?
When properly scoped and executed, VAPT is designed and controlled to minimise operational impact and prevent data loss or service disruption.
