Web Application Penetration Testing

Combining automated analysis with deep manual testing.

Overview

Web Application Penetration Testing evaluates the security of web applications and APIs against realistic attack scenarios. We combine advanced automated analysis with deep manual testing to identify vulnerabilities in authentication, access controls, business logic, session management, and application workflows that could lead to unauthorized access or data compromise, helping organizations reduce risk before those weaknesses are exploited.

Our Methodology

01 — Scoping & Planning

Before a web application assessment begins, we work closely with the client to define a clear testing scope and establish expectations for the engagement. This includes identifying which applications, domains, APIs, and environments are in scope, documenting any exclusions, and confirming testing windows to ensure the assessment aligns with business operations and security requirements.

02 — Information Gathering

We leverage OSINT techniques and passive reconnaissance to collect publicly available information related to the target application and organization. This may include exposed files, leaked credentials, subdomains, third-party services, technology stacks, and other intelligence that could assist an attacker in understanding the environment.

03 — Enumeration & Vulnerability Analysis

We perform comprehensive enumeration and in-depth testing of the application surface, including APIs, authentication mechanisms, session management, input handling, and application workflows. Automated tooling combined with manual analysis is used to identify vulnerabilities such as SQL Injection, Cross-Site Scripting (XSS), access control issues, insecure configurations, and business logic flaws that automated scanners often fail to detect.

04 — Exploitation & Validation

Where appropriate, we safely validate vulnerabilities through controlled exploitation to demonstrate realistic impact. This may include unauthorized access, account compromise, privilege escalation, or sensitive data exposure. All findings are manually verified to eliminate false positives while maintaining application stability.

05 — Reporting & Remediation Guidance

We provide a detailed report outlining identified vulnerabilities, attack paths, business impact, and prioritized remediation recommendations. Reporting is tailored for both technical teams and leadership, with clear explanations and actionable guidance. If requested, we also conduct an out-briefing or executive walkthrough of the assessment findings.

06 — Re-Testing & Validation

As an additional service, after remediation efforts are completed, we can perform a follow-up assessment to validate that vulnerabilities have been properly addressed. This includes verifying configuration changes, confirming patches are applied successfully, and ensuring no new security weaknesses were introduced during remediation.
