Web Application Pentest

Web Application Pentest

Web applications are a primary attack surface for modern organizations. From customer portals and internal dashboards to APIs and cloud-hosted services, vulnerabilities in web applications can lead to data breaches, account takeovers, business logic abuse, and regulatory violations.

Our Web Application Penetration Testing service goes beyond automated vulnerability scanning. We perform in-depth manual testing to identify security weaknesses, logic flaws, and real-world attack paths that could be exploited by attackers—providing clear, actionable remediation guidance tailored to your application.

Our Service Methodology

  1. 1

    Scoping & Planning

    We define assessment objectives, identify in-scope applications and APIs, review authentication requirements, understand the business context, and align testing with your development and security teams to ensure a controlled and non-disruptive engagement.

  2. 2

    Reconnaissance & Information Gathering

    We map application functionality, user roles, input points, API endpoints, and underlying technologies to understand how the application behaves and where security weaknesses may exist.

  3. 3

    Threat Modeling & Attack Surface Analysis

    We analyze high-risk features such as authentication flows, authorization controls, data processing logic, and sensitive functionality to prioritize attack paths based on real-world business impact.

  4. 4

    Vulnerability Discovery & Exploitation

    We perform targeted testing using a combination of automated scanning and deep manual techniques to identify exploitable vulnerabilities, configuration weaknesses, and logic flaws.

  5. 5

    Post-Exploitation & Risk Assessment

    Where applicable, we assess the impact of identified issues by evaluating data exposure, account compromise scenarios, privilege escalation opportunities, and potential lateral movement through integrated systems.

  6. 6

    Reporting & Remediation Support

    You receive a comprehensive report with an executive summary, detailed findings, proof-of-concept evidence, CVSS scoring, and prioritized remediation guidance. A complimentary retest is included to verify fixes.

What We Test

Authentication & Session Management

We test login mechanisms, password policies, MFA implementations, session handling, token usage, and logout behavior to identify bypasses, fixation issues, and session abuse risks.

Authorization & Access Control

We identify horizontal and vertical privilege escalation issues, insecure direct object references (IDOR), missing function-level access controls, and role enforcement weaknesses.

Input Validation & Injection Flaws

We test for SQL injection, NoSQL injection, command injection, template injection, and other input-handling vulnerabilities that could lead to data compromise or remote code execution.

Client-Side & Browser Security

We assess cross-site scripting (XSS), cross-site request forgery (CSRF), clickjacking, CORS misconfigurations, and client-side trust assumptions.

Business Logic Vulnerabilities

We evaluate application workflows to identify logic flaws such as workflow bypasses, race conditions, price manipulation, and abuse of application functionality.

File Handling & Upload Features

We test file upload mechanisms, download endpoints, and content handling for insecure validation, file execution risks, and data exposure.

API Security

We assess REST and GraphQL APIs for authentication flaws, authorization gaps, excessive data exposure, rate-limiting issues, and OWASP API Top 10 risks.

Configuration & Deployment Issues

We identify insecure headers, verbose error messages, exposed admin interfaces, debug features, outdated components, and misconfigurations.
