Web Application Penetration Testing

A web application penetration test goes far beyond automated scanning. Intelliroot's certified testers manually probe your application for logic flaws, authentication weaknesses, injection vulnerabilities, and business-logic bypasses that scanners consistently miss. Every test is conducted against the OWASP Web Security Testing Guide and rated using CVSS 3.1.

Whether you need a black-box assessment simulating an external attacker, a grey-box test with authenticated access, or a white-box review using full source code, we tailor the engagement to your risk profile and compliance obligations.

Why Your Organisation Needs Web App Testing

Web Apps Are the #1 Attack Vector

Over 75% of cyberattacks target the application layer. Scanners catch less than 30% of critical vulnerabilities found by manual testing.

Compliance Requires It

PCI DSS, ISO 27001, SOC 2, RBI, SEBI, and CERT-In all mandate periodic penetration testing of internet-facing applications.

Business Logic Flaws Are Invisible

Price manipulation, account takeover, and privilege escalation through logic flaws cannot be detected by automated tools — only skilled manual testing finds them.

Prioritised, Actionable Results

Every finding includes proof-of-concept evidence, risk rating, business impact, and step-by-step remediation guidance — not just a CVE list.

Ideal for These Organisations

FinTech & BankingInternet banking portals, payment gateways, and mobile money apps handling sensitive financial data.
E-CommerceOnline stores handling card data, customer PII, and high-value transactions requiring PCI DSS compliance.
HealthcarePatient portals, EMR systems, and health platforms requiring HIPAA and data protection compliance.
SaaS ProvidersMulti-tenant SaaS platforms where tenant isolation, privilege escalation, and data leakage are critical risks.
Government & PSUsCitizen-facing portals and internal systems requiring CERT-In empanelled audit certification.
Enterprise ApplicationsERP, CRM, and custom internal web applications exposed to employees or partners.

What We Test

Authentication & Session Management

  • Brute force and credential stuffing resistance
  • Multi-factor authentication bypass
  • Session token entropy and fixation
  • Insecure password reset flows
  • OAuth 2.0 and SSO implementation flaws

Injection & Data Exposure

  • SQL, NoSQL, LDAP, and OS command injection
  • Cross-Site Scripting (Reflected, Stored, DOM)
  • XML External Entity (XXE) processing
  • Server-Side Request Forgery (SSRF)
  • Sensitive data exposure and insecure storage

Access Control & Business Logic

  • Broken Object Level Authorisation (IDOR)
  • Horizontal and vertical privilege escalation
  • Business logic bypass (price manipulation, workflow abuse)
  • Mass assignment and parameter tampering
  • Insecure Direct Object Reference

Infrastructure & Configuration

  • Security misconfigurations and default credentials
  • HTTP security headers assessment
  • TLS/SSL configuration and certificate review
  • Content Security Policy evaluation
  • Third-party component vulnerability analysis

Our Testing Approach

01

Scoping & Rules of Engagement

Define test scope, target URLs, test accounts, IP whitelisting requirements, and blackout periods. Agree on testing mode (black/grey/white-box) and notification protocols.

02

Reconnaissance & Mapping

Map the application surface: enumerate endpoints, parameters, authentication mechanisms, and third-party integrations using passive and active reconnaissance techniques.

03

Automated Baseline Scanning

Run calibrated automated scans (Burp Suite Pro, OWASP ZAP, Nikto) to establish a vulnerability baseline and identify low-hanging fruit before manual deep-dive.

04

Manual Exploitation & Logic Testing

Conduct in-depth manual testing across all OWASP WSTG categories — focusing on authentication, authorisation, business logic, and injection vulnerabilities that automated tools miss.

05

Risk Analysis & CVSS Scoring

Analyse findings for exploitability and business impact. Assign CVSS 3.1 scores and contextual risk ratings (Critical/High/Medium/Low/Informational) based on your environment.

06

Reporting & Debrief

Deliver a detailed technical report with proof-of-concept evidence and an executive summary. Present findings to your technical and management teams with remediation Q&A.

07

Free Retest for Critical Findings

After your team remediates critical and high findings, we conduct a complimentary retest to verify the fixes hold and issue a closure certificate for your compliance records.

Frequently Asked Questions

A typical web application assessment takes 3–10 business days depending on application complexity, number of user roles, and test mode. We provide a time estimate during scoping. Rush engagements can be accommodated for an additional fee.
Testing is designed to be non-disruptive. We avoid denial-of-service payloads and destructive operations on production. For higher-risk tests (e.g., automated scanning), we recommend a staging environment or scheduling during off-peak hours.
Black-box simulates an external attacker with no prior knowledge. Grey-box provides testers with credentials and partial documentation — the most common approach for application testing. White-box includes full source code access and is most thorough but also most time-intensive.
Yes. Intelliroot is a CERT-In empanelled information security auditing organisation. Our reports are accepted by CERT-In, RBI, SEBI, IRDAI, and other regulators for compliance submissions. We provide a signed audit certificate alongside the report.
Web application testing focuses on browser-based web apps. API security testing is available as a separate service and can be bundled at a discount. Mobile application testing (iOS/Android) is also available as a standalone engagement.
