Web ApplicationPenetration Testing

Synopsys OSSRA 2025 found 84% of codebases ship with known vulnerabilities, and Veracode reports only 27% of critical flaws get fixed within 30 days. OSCE³/OSWE-certified testing finds the business-logic and auth bypasses scanners miss before attackers collect a $3,000 bounty on your app.

Why Choose Expert-Driven Testing?

96% of modern applications depend on open-source components, and 84% carry known vulnerabilities attackers actively exploit. Automated DAST and SAST tools cannot validate business-logic flaws, chained auth bypasses, or API abuse. OSCE³/OSWE-certified manual testing delivers verified findings with business-context risk ratings and zero false positives.

Complete OWASP Top 10 Coverage

Testing aligned with the OWASP Web Security Testing Guide (WSTG) and current Top 10 risk categories, including 2025 updates on broken access control, software supply chain, and SSRF. Every finding manually verified with proof-of-concept exploitation.

01

A01 Broken Access Control

IDOR, path traversal, privilege escalation, insecure direct object references, missing function level access control

02

A02 Cryptographic Failures

Weak encryption, sensitive data exposure, insecure transmission, broken SSL/TLS, weak hashing algorithms

03

A03 Injection

SQL, NoSQL, OS command, LDAP, XPath injection, ORM injection, template injection, expression language injection

04

A04 Insecure Design

Business logic flaws, workflow bypasses, race conditions, missing security controls, threat modeling gaps

05

A05 Security Misconfiguration

Default credentials, unnecessary features, verbose errors, missing security headers, unpatched systems

06

A06 Vulnerable Components

Outdated libraries, known CVEs, supply chain risks, vulnerable dependencies, unmaintained software

07

A07 Authentication Failures

Broken session management, credential stuffing, weak passwords, missing MFA, session fixation

08

A08 Data Integrity Failures

Insecure deserialization, code injection, CI/CD pipeline attacks, auto-update without verification

09

A09 Security Logging Failures

Insufficient logging, missing monitoring, inadequate alerting, log injection, tamperable logs

10

A10 Server-Side Request Forgery

SSRF attacks, internal network access, cloud metadata exploitation, port scanning, bypass controls

Beyond OWASP Top 10

PCI-DSS Web Application Testing

PCI-DSS Requirement 6.4.3 requires web application security testing for payment systems. I deliver OWASP-aligned assessments with attestation letters your QSA can accept, without the generic scanner output that fails audit scrutiny.

OWASP-Based Testing

OWASP WSTG methodology mapped to PCI-DSS 6.4.3, covering injection, access control, and authentication the way auditors expect, not how scanners approximate it

Compliance Reporting

Requirement-mapped reports with executive summaries and attestation letters, evidence your QSA needs, not a raw vulnerability export

Annual & Change Testing

Annual baseline and post-change validation so new releases do not reintroduce the flaws HackerOne researchers would report for a $3,000 critical bounty

Testing Services

Web App Pentesting

Full OWASP WSTG coverage: authentication, authorization, injection, business logic, and session management. Manual exploitation with proof-of-concept for every critical finding.

API Security Testing

REST, GraphQL, and SOAP testing for BOLA, broken authentication, rate-limit bypass, mass assignment, and injection, where modern breach chains actually start.

Compliance Testing

PCI-DSS, HIPAA, and SOC 2 focused assessments with requirement-mapped reporting and attestation letters your auditors can act on.

The Process

OWASP WSTG methodology with manual verification at every stage, because Veracode's 2025 data shows automated tools alone cannot close the remediation gap

01

Reconnaissance & OSINT

Attack surface mapping, exposed credentials, API discovery, and SSL/TLS analysis, building the same picture a bug bounty hunter would

02

Manual Expert Testing

Full OWASP Top 10 and WSTG coverage plus business-logic abuse, auth bypass chains, and creative exploitation beyond scanner playbooks

03

Detailed Reporting

Executive summary, technical findings with PoC evidence, prioritized remediation steps, and a live debrief your engineers can ask questions in

Common Questions

How long does it take?

Most engagements run 2-4 weeks depending on application complexity, API surface area, and authentication scope

What makes you different?

OSCE³/OSWE certified expertise with manual verification on every finding: no scanner noise, only exploitable vulnerabilities with business-context risk ratings

Automated scanner vs manual testing?

Scanners miss business-logic flaws, chained auth bypasses, and API abuse. I manually exploit and document every critical finding with proof-of-concept evidence

Production or staging?

Staging is preferred for depth testing. Production testing is available for PCI-DSS compliance with coordinated windows and safe exploitation techniques
