Center of Excellence Security - Web Application Penetration Testing

Web Application Penetration Testing

In today’s ever-evolving digital landscape, ensuring the security of your applications is paramount. Our Application Penetration Testing services are designed to identify critical vulnerabilities and fortify your web, mobile, and cloud-based applications against potential threats.

Web Application Penetration Testing at COE Security

At COE Security, our Web Application Penetration Testing service helps organizations proactively identify and remediate vulnerabilities in their web-based applications before adversaries can exploit them. As digital platforms grow increasingly complex and interconnected, securing your web applications is essential for protecting sensitive data, maintaining customer trust, and meeting compliance requirements.

We simulate real-world attack scenarios using both manual and automated techniques to uncover vulnerabilities such as SQL injection, authentication flaws, insecure direct object references, and more. Our testing approach aligns with the OWASP Top 10 and industry best practices, delivering clear, actionable results that enhance your application’s security posture.

With COE Security’s Web Application Penetration Testing, you gain the clarity and confidence needed to ship secure, resilient, and trustworthy applications.

Our Approach

Define scope and gather application details: Identify all target domains, features, environments, and technologies to be included in the testing engagement.
Perform reconnaissance and asset discovery: Collect public data, enumerate endpoints, and map the application structure, inputs, and third-party integrations.
Analyze authentication and session management: Evaluate login workflows, session tokens, password policies, and protection against brute force or bypass attempts.
Test access control and authorization: Check horizontal and vertical privilege escalation, direct object references, and role-based access logic flaws.
Check input validation and injection flaws: Fuzz inputs for SQLi, XSS, command injection, NoSQLi, and other user-input-driven vulnerabilities.

Assess business logic and workflow flaws: Test for insecure process flows, logic bypasses, or misuses that violate application design assumptions.
Evaluate file handling and upload security: Attempt unsafe file uploads, path traversal, or improper file type and MIME-type enforcement checks.
Review client-side and JavaScript exposures: Analyze JavaScript, DOM, and browser behaviors for leaks, insecure storage, and client-side logic flaws.
Inspect security controls and headers: Check for missing HTTP security headers, misconfigured CSP, insecure cookies, or weak TLS implementations.
Report findings with PoCs and fixes: Provide detailed technical findings, proof-of-concepts, and prioritized remediation steps with validation support.

Five Areas of Web Application Penetration Testing

Application Penetration Testing

Our Application Penetration Testing service is designed to identify and exploit vulnerabilities in your web applications, simulating real-world cyberattacks to uncover weaknesses that could be exploited by malicious actors. We focus on common web application threats, such as cross-site scripting (XSS), SQL injection, authentication flaws, and insecure session management. By mimicking a range of attack techniques, we reveal potential security gaps and provide actionable recommendations to mitigate them. This proactive testing approach ensures your web applications are resilient to attacks, protecting sensitive data and maintaining the trust of your users.

Penetration Testing as a Service

Our Penetration Testing as a Service (PTaaS) offers continuous, on-demand security testing for your web applications. This service goes beyond a one-time vulnerability scan by providing ongoing assessments to ensure your applications remain secure against emerging threats. With regular testing cycles, we simulate various attack vectors, such as cross-site request forgery (CSRF), remote code execution, and privilege escalation, to assess your app’s resilience over time. Through this continuous service, we ensure that your web applications are always up-to-date with security best practices and provide timely insights into new vulnerabilities as they emerge.

API Penetration Testing

Modern web applications often rely on APIs for seamless functionality, which makes securing APIs crucial. Our API Penetration Testing service focuses on evaluating the security of your web application’s APIs, identifying potential weaknesses like improper authentication, insecure data transmission, and lack of input validation. We test for common API vulnerabilities, such as broken access controls and authorization flaws, which could expose your system to attacks. By identifying and securing these weak points, we ensure that your APIs are fully protected, preventing attackers from bypassing your web application’s security measures and compromising sensitive data.

Application Security Consulting

In addition to testing, our Application Security Consulting service provides strategic guidance to help you build and maintain secure web applications. We assist your development and security teams by integrating security best practices into every stage of the web application lifecycle—from design and development to deployment and maintenance. Our consulting services cover secure coding, threat modeling, vulnerability management, and application hardening. We ensure that your team is equipped with the tools and knowledge to prevent common vulnerabilities and reduce the risk of future exploits, resulting in more secure, resilient web applications.

Cloud Security Consulting

As web applications increasingly rely on cloud-based infrastructure, it’s essential to ensure that your cloud environment is secure. Our Cloud Security Consulting service helps you assess and secure the cloud services supporting your web applications. We focus on areas such as access control, encryption, identity management, and security configuration to prevent misconfigurations that could expose your application to attacks. Whether your app is hosted on AWS, Azure, or another cloud provider, we guide you in implementing robust cloud security practices that align with industry standards and best practices, ensuring that your web application and associated data are fully protected in the cloud environment.
