Web Penetration Testing: Critical For Secure Web Applications 

Core Penetration Labs leads the industry in web application penetration testing, identifying vulnerabilities in various programming languages and environments.
From web apps in highly scalable AWS environments to legacy apps in traditional infrastructure, our security experts have helped secure data worldwide.

Hunting Vulnerabilities In Webapps & APIs 

The best defense is a good offense. By hiring a knowledgeable team of penetration testers to assess your application, you will be aware of every security hole that could lead to compromised applications and data breaches. That will provide you with the foresight needed to fortify your web application and keep your most sensitive assets where they belong.

Our Web Pen-test Methodology

Core Penetration Testing Labs operates under a structured, repeatable methodology. We prioritize this concept in each engagement to make certain that our assessment is reliable, reproducible, and top-notch in quality. As such, our findings can always be verified by your team, before and after the remediation. To get these results, we are guided by the following steps:

Define Scope

Before a web application assessment can take place, Core defines a clear scope of the client. Open communication between Core and the client organization is encouraged at this stage to establish a comfortable foundation from which to assess.

Determine which of the organization’s applications or domains  are to be scanned/tested

Make exclusions from the assessment known (specific pages/subdomains)

Decide on the official testing period and confirm time zones

Information Gathering

Core engineers collect as much information as they can on the target, employing a myriad of OSINT (Open Source Intelligence) tools and techniques. The gathered data will help us to understand the operating conditions of the organization, which allows us to assess risk accurately as the engagement progresses. Targeted intelligence might include:

PDF, DOCX, XLSX, and other files leaked by Google

Previous breaches/credential leaks

Revealing forum posts by application developers

Exposed robots.txt file


At this stage, we incorporate automated scripts and tools, among other tactics, in more advanced information gathering. Core engineers closely examine any possible attack vectors. The gathered information from this stage will be the basis for our exploitation in the next phase.

Enumerating directories/subdomains

Checking cloud services for possible misconfigurations

Correlating known vulnerabilities with the application and relevant services

Attack and Penetration

With careful consideration, we begin to attack vulnerabilities found within the web app. This is done cautiously to protect the application and its data while still verifying the existence of discovered attack vectors. At this stage, we may perform attacks such as:

SQL injection and Cross-Site Scripting

Employing breached credentials and brute force tools against authorization mechanisms

Monitoring web app functionality for insecure protocols and functions


Reporting is the final stage of the assessment process. Core analysts aggregate all obtained information and provide the client with a thorough, comprehensive detailing of our findings. The report begins with a high-level breakdown of the overall risk, highlighting both strengths and weaknesses in the application’s protective systems and logic. We also include strategic recommendations to aid business leaders in making informed decisions regarding the application. Further, we break down each vulnerability in technical detail into the report, including our testing process and remediation steps for the IT team, making for a simple remediation process. Finally, we go to great lengths to ensure each report is both explicit and easy to navigate.

Remediation Testing

Additionally, Core Security Labs may review an assessment upon the client's request after the client organization has patched vulnerabilities. We will ensure changes are correctly implemented and the risk has been eliminated. The previous assessment will be updated to reflect the more secure state of the application.
