What is Web Application Penetration Testing?
Why Conduct a Web App Pentest?
Conducting a penetration test of your web application provides invaluable insights into the potential threats that may compromise the cybersecurity of your app and its end users. Here is what you will get after conducting a project with our team:
Validate your existing security controls
Our tests will test the effectiveness of your app’s existing security controls in preventing and detecting attacks. By simulating an attacker, our experts will identify gaps in your defenses and provide remediation measures to improve your ability to prevent attacks.
Understand the potential impact of an attack on your Web App
Our tests will identify and measure vulnerabilities that could be exploited to gain unauthorized access to sensitive data, administrative features, or damage your reputation. By understanding exactly what could happen during an attack, organizations can prioritize their security efforts and allocate resources effectively.
Identify & fix of all existing vulnerabilities
Our team will help you identify all existing vulnerabilities in your web application and its underlying hosting infrastructure, whether it’s cloud-based or in-house. The test will result in prioritized remediation steps to help reduce your overall risk exposure.
Improve your Web application's security
Our services will provide detailed information on how an attacker can breach your Web App, what data or critical systems they could target and how to protect them. With this information, our team will provide you with tailored recommendations to improve your application’s security posture and protect it against potential threats.
Comply with regulatory requirements
Many regulatory frameworks require web application penetration testing as part of their compliance requirements. Our tests will help your organization meet these requirements effortlessly, by providing an official attestation that your risks have been successfully mitigated following remediation testing.
Enhance your development practices
Gain a deeper understanding of development processes that might inadvertently introduce security risks, allowing you to develop more secure applications and features in the future.

Manual vs. Automated Web Application Penetration Testing
While it can be a great starting point for organizations unable to conduct frequent manual testing, application security risks cannot be sufficiently mitigated by relying on automated testing solutions alone.
Here are examples of high/critical vulnerabilities that can only be identified through manual testing:
Business logic flaws
These vulnerabilities occur when an attacker manipulates the application’s logic to achieve unintended results. Due to the application-specific nature of these flaws, automated tools often struggle to detect them, making manual testing crucial for identifying and mitigating these risks.
Privilege escalation
This vulnerability enables attackers to elevate their access level from a lower privilege to a higher one, gaining unauthorized access to sensitive data or functionality. Automated tools might not be effective in identifying customized implementations, making manual testing a necessary component.
Access control bypass
This vulnerability occurs when an attacker gains unauthorized access to restricted resources by bypassing access control mechanisms. As automated tools may not catch all instances of access control bypass, manual testing is vital to uncover these risks.
Authorization bypass
A vulnerability that allows an attacker to circumvent the authorization process to access restricted resources without proper permissions. Automated tools might not be able to detect complex bypass scenarios, which is why manual testing is essential.
Non-authenticated access
A vulnerability that allows unauthorized users to access protected resources without providing valid authentication credentials. Automated tools may have difficulty detecting specific scenarios in which authentication is bypassed, highlighting the need for manual testing.
Session management flaws
Vulnerabilities related to the improper handling of user sessions, making it possible for attackers to hijack or manipulate user sessions. Automated tools may not be able to identify every possible session management issue, requiring manual testing to ensure comprehensive security.

When Should You Perform a
Web Application Penetration Test?
- After significant changes to the application or infrastructure
- When adding new, sensitive features or functionality
- Following a security incident or breach
- As part of a regulatory or compliance audit
- Prior to an M&A transaction or other major business event
- In response to new vulnerabilities identified in technologies used
Our Web Application Penetration Testing Process
If your organization has not gone through a penetration test before, you may not know what to expect. Even if you have, maybe you are wondering what Vumetric’ stages of penetration testing are. Here is a high-level break down of each step of our proven process:
Project Scoping
Duration: ~ 1-2 days
Activities: We learn about your specific needs and objectives.
Outcome: Business proposal, signed contract.
Kick-off / Planning
Duration: ~ 1 hour
Activities: We review the scope of work, discuss requirements and planning.
Outcome: Scope validation, test planning.
Penetration Testing
Duration: ~ 2-3 weeks
Activities: We execute the test in accordance with the project scope.
Outcome: Detailed penetration test report, presentation.
Remediation Testing
Duration: Up to 1 month
Activities: We test and validate vulnerability fixes.
Outcome: Remediation report, attestation.

The purpose of this test is to identify vulnerabilities and gaps in your web applications’ security and provide prioritized improvement recommendations, ensuring their security, protecting users and preventing potential attacks from cybercriminals.
A web application penetration test is conducted using a systematic approach, including reconnaissance, scanning, gaining access, maintaining access, and covering tracks. The process involves manual testing, automated tools, and ethical hacking techniques based on standards such as OWASP to simulate real-world attacks and identify vulnerabilities.
To begin the test, you will need to provide the target web applications’ URLs, login credentials depending on the approach, and the scope of the test (e.g., specific functionality or features to focus on).
In most cases, no initial access is required as we typically use a black box approach to simulate real-world attacks. However, for certain tests and to evaluate specific features, some access may be necessary. Any access requirements will be discussed and agreed upon with your team during a pre-testing call to ensure a thorough assessment while respecting your organization’s security and privacy concerns. This collaborative approach allows us to tailor the testing process to your organization’s unique needs and requirements.
Our external penetration tests are designed to minimize disruption to your organization’s normal operations and the overwhelming majority of our tests are unnoticeable to our clients. Our team will work with you prior to the project launch to determine any areas that may be susceptible to affect your productivity and will take the necessary steps to minimize any potential impact.
Performing a penetration test of your web application is now considered as an essential step of your development lifecycle. This test is critical in identifying weaknesses in your web applications, allowing you to proactively address vulnerabilities in your web app and improve your organization’s overall cybersecurity posture.
Yes, our web application penetration tests helps several organizations of all types meet compliance requirements every year by identifying and fixing vulnerabilities that need remediation. Once remediation testing is completed, we provide an official attestation confirming that vulnerabilities have been remediated, helping organizations meet compliance requirements efficiently.
