VAPT — Vulnerability Assessment & Penetration Testing
A scanner tells you what is unpatched. A penetration test tells you what an attacker would actually do with it. Vyapari Solutions runs manual-led testing against your applications, APIs, cloud and network — then retests the fixes for free.

Assessment versus penetration test
Vulnerability assessment is breadth: authenticated and unauthenticated scanning across your estate to enumerate known weaknesses and misconfigurations. Penetration testing is depth: a human attempts to chain those weaknesses into real impact — data access, privilege escalation, lateral movement, financial manipulation.
You need both. Automated tooling gives coverage and repeatability; manual testing finds the business logic flaws that no scanner will ever detect — broken object-level authorisation, price manipulation, workflow bypass, race conditions in payment flows.
- Web application testing to OWASP Top 10 and ASVS Level 2 depth
- Mobile application testing for Android and iOS against OWASP MASVS, including static, dynamic and runtime analysis
- API security testing for REST, GraphQL and SOAP against the OWASP API Security Top 10
- Internal and external network penetration testing with Active Directory attack path analysis
- Cloud configuration review for AWS, Azure and Google Cloud against CIS Benchmarks
- Thick client, IoT/OT, Wi-Fi, source code review and social engineering simulations

Our testing services
Every engagement is scoped on real attack surface — number of dynamic endpoints, roles, integrations and privilege boundaries — not on a per-IP price list.
Web application VAPT
Authentication, session, authorisation, injection, SSRF, deserialisation, file handling and full business logic testing across every user role.
Mobile application VAPT
Reverse engineering, insecure storage, certificate pinning bypass, IPC abuse, root/jailbreak detection and backend API testing.
API security testing
BOLA/IDOR, broken function-level authorisation, mass assignment, rate limiting, token handling and schema abuse.
Network penetration testing
External perimeter and internal lateral movement, AD misconfiguration, credential attacks and segmentation validation.
Cloud security assessment
IAM privilege escalation paths, exposed storage, key management, logging gaps and CIS Benchmark deviations.
Red team simulation
Objective-based, multi-vector adversary emulation mapped to MITRE ATT&CK, with a purple team debrief for your SOC.
When you need VAPT
Testing is often triggered by a compliance clock, but the highest value comes from testing before a release, not after an audit finding.
- Annual and post-change testing required by PCI DSS, ISO 27001, SOC 2, RBI, SEBI and IRDAI
- CERT-In directions and empanelled-auditor reports required for government and BFSI filings
- Pre-launch assurance for a new product, major release or cloud migration
- Post-incident validation that the root cause and lateral paths are genuinely closed
- Customer or investor due diligence requiring an independent security report
Findings you can act on
Every issue carries reproduction steps, PoC evidence, CVSS v3.1 rating, business impact and a specific code or config fix.
Free remediation retest
We verify each fix and reissue the report — you get a clean closure record for auditors and customers.
Two audiences, two reports
A board-level executive summary and a developer-level technical report, so no one has to translate.
Zero-downtime testing
Rate-limited, out-of-hours and staging-first options for production systems, with a rollback contact on call throughout.
How the engagement runs
Scoping & rules of engagement
Targets, roles, credentials, test windows, escalation contacts and legal authorisation confirmed and signed.
Reconnaissance & mapping
Attack surface enumeration, technology fingerprinting, endpoint and role mapping across the full application.
Automated + manual testing
Tool-assisted coverage followed by manual exploitation of authorisation, logic and chained vulnerabilities.
Exploitation & impact proof
Controlled exploitation to demonstrate real business impact, never destructive, always evidenced.
Report, debrief & retest
Prioritised report, developer walkthrough session, then a full retest and closure certificate after remediation.
What you receive
- Executive summary with risk posture and trend against previous tests
- Technical findings report with CVSS scores, PoC and reproduction steps
- Attack path narrative showing how findings chain into business impact
- Prioritised remediation plan with effort estimates and owners
- Developer debrief session and remediation Q&A support
- Retest report and remediation-verified security testing certificate
- Compliance mapping to PCI DSS 11.4, ISO 27001 A.8.8, SOC 2 CC7 and CERT-In requirements
VAPT — frequently asked questions
At minimum annually, and after any significant change to the application, infrastructure or authentication model. PCI DSS mandates annual plus after significant change; most SaaS companies test each major release and run continuous scanning between tests.
No. We use rate-limited, non-destructive techniques, agree test windows with your team, keep an escalation contact live throughout, and stop immediately on any sign of instability. Denial-of-service testing is only ever performed on explicit written request in an isolated environment.
Grey box gives the best return for most applications — we get credentials for each role, which lets us find authorisation flaws that a black box test would never reach, while still simulating a real attacker. White box adds source code review and is worth it for payment, cryptography and authentication code.
Yes. After remediation and retest we issue a Security Testing Certificate stating scope, methodology, test dates and confirmation that identified issues were remediated. Auditors and enterprise buyers accept it as evidence of testing under PCI DSS, ISO 27001 and SOC 2.
Yes, one full retest of all findings within 90 days of the original report is included in the fee. We do not charge you again to check that our own findings were fixed.
Yes. We test against the OWASP Top 10 for LLM Applications — prompt injection, insecure output handling, training data poisoning, model denial of service, sensitive information disclosure and excessive agency — including the tool and plugin permissions your agents hold.
