Web Application Penetration Testing Services

ImmuniWeb® Discovery Powered by ImmuniWeb On-Demand

Hybrid human + AI web application penetration testing built on our award-winning ImmuniWeb® On-Demand platform. We pair machine-speed scanning with senior pentesters to find the business-logic flaws automated tools miss across OWASP Top 10 and SANS Top 25 — delivered with a contractual zero false positives SLA.

Why Web Penetration Testing Is a Business Revenue Lever

Your web app is where customers transact, sign up and share data — and where a single access-control flaw can expose your whole database, trigger fines and stall enterprise deals stuck in security review. Treating web pentesting as a revenue enabler, not a compliance tax, shortens sales cycles, protects recurring revenue and turns your security posture into a competitive advantage.

Comparison matrix:

With an ImmuniWeb Web Pentest

  • Enterprise deals clear security review faster with an audit-ready report
  • Vulnerabilities caught pre-production, before they reach customers
  • Predictable fixed fee with zero false positives to triage
  • Continuous compliance evidence for PCI DSS, SOC 2 and GDPR
  • Developer trust: actionable, verified, noise-free findings

Without Web Penetration Testing

  • Deals stall or collapse in vendor security questionnaires
  • Zero-day exposure of customer data and sessions in production
  • Hidden cost of breach response, fines and customer churn
  • Failed audits and blocked market entry
  • Alert fatigue from false positives; real risks ignored

Automated Web Scanning vs Manual Penetration Testing

Automated Scanning Manual Penetration Testing
Duration Minutes to hours, on every commit A few days, scheduled per release or audit
Cost Low, subscription-based Higher, project-based fixed fee
Scope Known signatures, OWASP patterns Business logic, chained exploits, auth & access-control bypass
Best For Daily CI/CD regression Audits, compliance, high-risk and pre-launch apps
Report Automated findings list Validated, manually exploited, remediation-ready report

Recommendation: Automated scanning is essential for daily CI/CD hygiene and catching regressions fast. But for audits, compliance sign-off and apps handling sensitive data, manual penetration testing is mandatory — only a human tester can chain logic flaws into a real exploit. ImmuniWeb® On-Demand combines both in a single engagement.

Comprehensive Web Application Testing Scope

Every engagement covers your full web surface — authenticated and unauthenticated. We test across four dimensions:

Authentication & Session Management

  • • Login, SSO and MFA bypass testing
  • • Session fixation, hijacking and token handling
  • • Password reset and account-recovery abuse
  • • Privilege escalation and access-control (IDOR) testing

Injection & Input Handling

  • • SQL, NoSQL, command and template injection
  • • Cross-site scripting (stored, reflected, DOM)
  • • Server-side request forgery (SSRF)
  • • File upload and deserialization flaws

Detection & Response Assessment

  • • Workflow bypass, race conditions and abuse cases
  • • Price/quantity tampering and checkout manipulation
  • • Sensitive data exposure in responses and errors
  • • CSRF and state-changing request testing

Configuration, Components & Standards

  • • Security headers, CORS, CSP and TLS review
  • • Vulnerable & outdated components (SCA, 20,000+ CVEs)
  • • API and web-service endpoints behind the app
  • • Alignment with OWASP Top 10 and SANS Top 25

OWASP Top 10 (2021) Vulnerability Mapping

A01 Broken Access Control

We test for IDOR, privilege escalation and missing function-level checks.

A02 Cryptographic Failures

We check TLS, weak hashing and sensitive data exposed in transit or at rest.

A03 Injection

We probe SQL, NoSQL, command and template injection across all inputs.

A04 Insecure Design

We review trust boundaries and abuse cases the architecture allows.

A05 Security Misconfiguration

We review headers, CORS, error handling and default settings.

A06 Vulnerable & Outdated Components

We fingerprint libraries and frameworks against 20,000+ known CVEs.

A07 Identification & Authentication Failures

We attack login, SSO, MFA and session handling.

A08 Software & Data Integrity Failures

We test insecure deserialization and unverified update flows.

A09 Logging & Monitoring Failures

We assess whether attacks are detectable and logged.

A10 Server-Side Request Forgery (SSRF)

We test whether user-supplied URLs can reach internal systems.

The 6-Phase Web Pentest Workflow & Kill Chain

Scoping & Onboarding
We agree scope, credentials and test windows. Artifact: a scoping document and rules of engagement.

Phase 1

Phase 2

Passive OSINT & Reconnaissance
We map your exposed footprint, subdomains and leaked data. Artifact: an attack-surface reconnaissance summary.
Automated Scanning & Validation
Our AI engine scans the full app and analysts validate every finding. Artifact: a verified, false-positive-free shortlist.

Phase 3

Phase 4

Manual Exploitation
Senior pentesters chain logic and access-control flaws into real exploits. Artifact: code-level remediation hints with proof-of-concept.
Audit-Ready Reporting & Debrief
You receive a board- and auditor-ready report plus a live technical debrief. Artifact: full pentest report mapped to OWASP and compliance.

Phase 5

Phase 6

Retesting & Compliance Certification
We re-verify every fix with free unlimited retesting. Artifact: a signed compliance / VAPT certificate.

Shift-Left Security: DevSecOps & CI/CD Pipeline Automation

Catch web flaws before they ship. Set policy thresholds and vulnerable builds are blocked from deployment automatically — no manual review, no merge of insecure code. ImmuniWeb plugs natively into GitHub Actions, GitLab CI and Jenkins, turning every pipeline into an automated security gate, so developers get fast, actionable feedback inside the tools they already use.

Industry-Specific Web Threat Modeling

Web risk is not one-size-fits-all. We tailor the threat model to your sector:

FinTech & E-commerce
Payment-flow, checkout and transaction-integrity testing aligned with PCI DSS, plus protection against account takeover and fraud.
Healthcare & SaaS
PHI exposure and multi-tenant isolation testing aligned with HIPAA and GDPR, ensuring one customer can never reach another's data.
Public Sector & Enterprise
Access-control and data-leakage testing for high-assurance environments, mapped to NIST and ISO 27001 requirements.

Frequently Asked Questions

  • Q
    Do you test authenticated areas, SSO and MFA?
    A
    Yes. We perform authenticated testing using credentials you provide, including SSO and MFA flows, so we cover the areas real users and attackers reach.
  • Q
    Will the test disrupt my production site?
    A
    No. Testing is production-safe and scheduled with you; intrusive checks are run carefully within agreed windows to avoid downtime.
  • Q
    How do you guarantee zero false positives?
    A
    Every AI-detected finding is manually verified by a senior pentester before it reaches your report, backed by a contractual zero false positives SLA with a money-back guarantee.
  • Q
    Is retesting included?
    A
    Yes. Free unlimited retesting is included — once you apply a fix, we re-verify the affected areas at no extra cost so you can prove remediation to auditors.
