Web Application
VAPT

In-depth security testing for web applications. We cover OWASP Top 10, authentication bypass, business logic flaws, and API security, delivering CVSS-scored findings and a free re-test after you remediate.

What We Test on Your Web App

Purpose-built attack scenarios covering the application layer, authentication systems, and the APIs your web app depends on.

Injection Vulnerabilities

We test all user-controlled inputs for SQL injection, command injection, LDAP injection, and template injection using manual payloads and automated fuzzing to confirm exploitability.

Cross-Site Scripting (XSS)

We probe for reflected, stored, and DOM-based XSS across every input surface, including hidden parameters, HTTP headers, and JSON response injection points that scanners routinely miss.

SSRF and XXE

We identify server-side request forgery and XML external entity vulnerabilities that can expose internal services, cloud metadata endpoints, and sensitive configuration files.

File Upload and Path Traversal

We attempt malicious file uploads, extension bypass, and directory traversal to evaluate whether unrestricted access to the file system or remote code execution is achievable.

Sensitive Data Exposure

We identify credentials, tokens, and personal data leaking through error messages, HTTP responses, JavaScript source files, and insecure direct object references to internal resources.

Security Misconfiguration

We audit HTTP security headers, TLS configuration, directory listing exposure, default credentials, verbose error pages, and cloud storage permissions that leave data publicly accessible.

Broken Access Control

We test horizontal and vertical privilege escalation, insecure direct object references, and forced browsing to determine whether users can access resources beyond their intended permissions.

Authentication Bypass

We test MFA bypass, credential stuffing resilience, account lockout weaknesses, password reset flaws, and OAuth 2.0 and SAML implementation vulnerabilities across all login flows.

Session Management Flaws

We review session token entropy, expiry enforcement, fixation and hijacking risks, and improper invalidation on logout to expose weaknesses attackers use to impersonate authenticated users.

CSRF and Clickjacking

We verify that state-changing operations are protected with CSRF tokens and that framing protections prevent clickjacking attacks that trick users into performing unintended actions.

Client-Side Security

We test postMessage handling, service worker exploitation, DOM clobbering, prototype pollution, and insecure WebSocket connections that open client-side attack vectors.

JWT and Token Security

We probe JWT implementations for algorithm confusion, weak secret keys, missing signature validation, and insecure token storage patterns that allow account takeover.

API Endpoint Testing

We test every REST and GraphQL endpoint consumed by the web application for BOLA, mass assignment, excessive data exposure, and injection vulnerabilities using Burp Suite and custom tooling.

Business Logic Abuse

We identify flaws in application workflows including payment bypass, coupon and discount abuse, parameter tampering, race conditions, and order manipulation that bypass intended business rules.

Rate Limiting and Brute Force

We identify absent rate limits, account enumeration weaknesses, OTP bypass opportunities, and missing lockout controls across login, registration, and password reset endpoints.

Network Traffic Interception

Using Burp Suite and mitmproxy, we capture all HTTP and HTTPS traffic from the application to identify insecure endpoints, data leakage, and weak transport-layer controls.

TLS and Certificate Validation

We verify TLS implementation strength, cipher suite selection, and certificate validation logic to confirm protection against man-in-the-middle attacks and protocol downgrade.

Compliance-Ready Reporting

We deliver CVSS-scored findings with proof-of-concept evidence, an executive summary, and full OWASP Top 10 and CWE mapping suitable for SOC 2, PCI-DSS, and ISO 27001 audits.

How We Run a Web Application VAPT

A structured six-phase process built on OWASP ASVS and PTES, taking you from initial scoping through to verified remediation.

Phase 01
Scoping and Threat Modelling

We map the application's architecture, user roles, data flows, and authentication mechanisms, then build a threat model aligned to OWASP ASVS for the target environment.

01
02
Phase 02
Reconnaissance and Surface Mapping

We crawl the application to enumerate all endpoints, parameters, API routes, and JavaScript files, building a comprehensive attack surface map before active testing begins.

Phase 03
Automated Vulnerability Scanning

We run DAST scanners to identify low-hanging fruit including known CVEs, default credentials, misconfigurations, and common injection points across the full application surface.

03
04
Phase 04
Manual Exploitation and Logic Testing

Expert-led testing targets business logic flaws, authentication bypass, chained exploits, and privilege escalation scenarios that automated scanners consistently miss in real-world applications.

Phase 05
Privilege Escalation and Impact Analysis

We attempt lateral movement and privilege escalation to determine the real-world impact of each finding, providing business-context risk ratings beyond generic CVSS scores.

05
06
Phase 06
Reporting and Free Re-Test

We deliver a CVSS-scored report with proof-of-concept evidence, an executive summary, and full OWASP and CWE mapping. Once you remediate, we re-test every finding at no additional cost.

Built for Teams Who Ship Web Applications

SaaS and Web Platform Companies

Web-first businesses needing VAPT to satisfy SOC 2, PCI-DSS, HIPAA, and enterprise customer security requirements before and after product releases.

E-Commerce and FinTech

Online platforms handling payments, PII, and financial data where a single web vulnerability can directly impact revenue, user trust, and regulatory standing.

Regulated Enterprises

Organisations in banking, healthcare, and government with mandatory web application testing obligations under RBI, SEBI, IRDAI, and sector-specific compliance frameworks.

Questions We Get Asked Often

Web Application VAPT is a structured security assessment that combines automated scanning with expert manual testing. It identifies vulnerabilities including OWASP Top 10 categories such as injection, XSS, SSRF, broken access control, authentication bypass, and business logic abuse across your entire web application surface.

A typical engagement takes 2 to 4 weeks depending on application complexity, number of endpoints, authentication mechanisms, and scope. We provide a precise timeline after initial scoping, and our free re-test is included once your team completes remediation.

We need access to a staging or production environment, test credentials for all user roles, a list of in-scope URLs and API endpoints, and a brief overview of the application architecture. Testing begins after a signed scope document is in place.

Common findings include SQL and command injection, stored and reflected XSS, broken access control and IDOR, insecure authentication flows, CSRF on sensitive actions, SSRF to internal services, business logic bypass, and sensitive data exposure in API responses.

We align our methodology with the OWASP Testing Guide v4, OWASP Top 10, OWASP ASVS, and PTES frameworks. Every engagement includes OWASP Top 10 assessment, authentication and session testing, business logic abuse testing, and full API endpoint assessment.
