Web Application Penetration Testing

Comprehensive security assessment of your web applications following OWASP, NIST, and PTES industry standards.

Service Overview

Our web application penetration testing service provides a thorough security assessment of your web applications and APIs. We follow industry-recognized methodologies including NIST SP 800-115, PTES, OWASP WSTG 4.2, and OWASP Top 10 standards to identify vulnerabilities before attackers do.

Methodology

Our penetration testing methodology is based on NIST SP 800-115 and PTES frameworks, complemented by specialized web application security references including OWASP Web Security Testing Guide v4.2, OWASP Top 10 2025, and OWASP Top 10 API Security Risks 2023.

Testing Phases

1. Planning

Define scope, objectives, rules of engagement, and testing windows. Establish assets to be evaluated and technical constraints.

2. Discovery

Information gathering through passive and active reconnaissance, technology identification, service mapping, and configuration analysis.

3. Exploitation

Controlled exploitation of identified vulnerabilities to validate their existence and assess real-world impact without causing damage.

4. Post-Exploitation

Evaluate extent of compromise, lateral movement possibilities, persistence mechanisms, and impact on critical assets.

5. Reporting

Detailed documentation of findings with exploitation evidence, impact analysis, and technical remediation recommendations.

6. Retest

Verify effectiveness of applied corrections and ensure vulnerabilities have been properly mitigated without introducing new issues.

Risk Classification

Vulnerabilities are classified using CWE (Common Weakness Enumeration) and prioritized with CVSS v4.0 scoring: Critical, High, Medium, Low, and Informational.
