What is Web Application Penetration Testing?

Web Application Pen Testing is a cybersecurity practice aimed at securing your web applications against cyber threats. By simulating real-world hacking techniques, we identify vulnerabilities in your application and offer actionable countermeasures. In today’s digital ecosystem, web applications have become more complex and integral to business operations. As a result, they present an appealing target for cyber adversaries. Custom-designed, proprietary, and increasingly intricate web applications introduce complex and diverse security risks. That’s where our specialized expertise comes into play; we go beyond traditional application security assessments to protect against business logic flaws and advanced technical vulnerabilities.

With the tightening of compliance standards like PCI-DSS, ISO 27001, and SOC 2, the cybersecurity landscape is evolving to place more emphasis on web application security. These standards often include application-level security controls, adding another layer of requirements for organizations to navigate. Our Web Application Penetration Testing  help you achieve compliance efficiently, ensuring that your business operates securely and within regulatory boundaries.


Why Should you Perform a Web Application Penetration Test?

Why Manual Testing Complements Automated Web App Pen Testing

Automated testing solutions are a good start, but only allow for partial vulnerabilities coverage. To ensure robust application security,  manual testing is required. Here are examples of critical vulnerabilities only identified through manual testing:

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 vulnerability scanners often struggle to detect them, making manual web application pentest is crucial for identifying and mitigating these risks.

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.

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.

A vulnerability that allows an attacker to circumvent the authorization process to gain access to restricted resources without proper permissions. Automated scanners might not be able to detect complex bypass scenarios, which is why manual testing is essential.

A vulnerability that allows unauthorized users to gain access to protected resources without providing valid authentication credentials. Automated scanning tools may have difficulty detecting specific scenarios in which authentication is bypassed, highlighting the need for manual testing.

This vulnerability is related to the improper handling of user sessions, making it possible for attackers to hijack or manipulate user sessions. Automated scanning tools may not be sufficient for finding vulnerabilities in every possible session management issue, making consistent manual testing necessary for accurate identification.
