Web Application Penetration Testing
Beyond surface-level automated vulnerability scanners. Our seasoned offensive engineers conduct deep, manual penetration tests simulating nation-state threat actors to uncover complex authorization bypasses, multi-tenant leaks, and business logic flaws in your web applications.
Critical Attack Vectors We Actively Exploit
Automated tools check signatures; our engineers attack logic, state flows, and complex distributed architecture.
Broken Access Control & IDOR
Horizontal and vertical privilege escalation, tenant boundary cross-contamination, and insecure direct object reference exploitation across microservices.
Complex Business Logic Exploits
State machine subversion, payment tampering, discount manipulation, rate-limit bypassing, and financial transaction race conditions that scanners miss entirely.
Server-Side Request Forgery (SSRF)
Exploiting URL parsers, PDF generators, webhooks, and cloud metadata endpoints (`169.254.169.254`) to gain internal infrastructure access.
Auth & Session Vulnerabilities
MFA evasion, OAuth2 / OIDC state parameter manipulation, JWT cryptographic algorithm confusion (`none`, HS256/RS256), and session fixation.
Injection & Remote Code Execution
Second-order SQL injection, NoSQL injection, Server-Side Template Injection (SSTI), deserialization exploits, and OS command injection.
Client-Side SPA & DOM Security
DOM-based Cross-Site Scripting (XSS), prototype pollution in modern JS frameworks (React, Vue, Angular), and Content Security Policy (CSP) bypasses.
How We Execute Your Web Assessment
A battle-tested 5-stage framework ensuring comprehensive coverage without production disruption.
Recon & Mapping
Full route mapping, hidden endpoint discovery, technology fingerprinting, and API parameter enumeration.
Threat Modeling
Role matrix formulation, privilege tier mapping, and business logic trust boundary definition.
Manual Exploitation
Active exploitation of custom business logic, multi-tenant boundaries, and edge-case cryptographic vulnerabilities.
Reporting & Review
Executive summaries, reproducible video PoCs, CVSS 4.0 severity scoring, and copy-paste remediation code.
Remediation Retest
Verification of engineering patches with updated Attestation of Assessment for auditors and customers.
Audit-Ready Artifacts & Developer-First Reports
We deliver the exact evidence required by enterprise procurement, external SOC 2/ISO auditors, and engineering teams.
Concise, high-level risk overview designed for Board members, CISOs, and non-technical stakeholders summarizing business exposure.
Step-by-step reproduction steps, raw HTTP payloads, curl commands, and code-level patch snippets for engineering squads.
Verified cryptographic certificate and attestation letter suitable for enterprise customer due diligence, SOC 2, and PCI-DSS.
Frequently Asked Questions
Will web penetration testing cause downtime or disrupt production data? ↓
No. We coordinate testing windows and tailor traffic rates to your architecture. In production environments, destructive testing (such as blind fuzzing, heavy denial-of-service, or bulk record deletion) is strictly excluded or executed in staging mirrors.
How long does a standard web application penetration test take? ↓
Typical applications with 2–4 user privilege roles and 20–50 views require 5 to 10 business days of active testing, followed by 2 days for peer review and executive reporting.
What credentials or access do you require to begin? ↓
For comprehensive grey-box testing, we request at least two separate accounts for each user role (to test horizontal tenant isolation) and documentation or OpenAPI specifications if available.
Is a remediation re-test included in the engagement? ↓
Yes. Every web application assessment includes one comprehensive re-test within a 90-day window to verify your team's patches at no extra charge.
