Penetration test of a web application

...detect vulnerabilities before hackers exploit them

Websites and applications are key tools for organizations. Some serve only for presentation purposes, while others provide a business platform for the company. However, each of them can be misused. In some cases, this may only damage the company's reputation, while in others, the application may be used to gain access to the organization's internal networks. Misuse of a web application can have significant consequences for ordering systems or systems directly connected to your web application. By performing a penetration test of web applications, you can uncover weaknesses before they are exploited by a real attacker. We analyze the application from the perspective of real threats, from common vulnerabilities to sophisticated attacker techniques. We don't limit ourselves to automated tools, but go in-depth. After performing a web application penetration test, you will gain an overview of vulnerabilities and clear recommendations for their removal.

You Can Choose from the Following Options:

Small Web Application
Medium Web Application
Large Web Application

What you get with the service

/0 1

Comprehensive Penetration Testing of Websites or Web Applications

/0 2

A penetration test conducted beyond the scope of internationally recognized OWASP ASVS standards.

/0 3

Clear vulnerability ratings that are consistent and comparable with previous or future assessments, as we use the internationally accepted FIRST CVSS standard.

/0 4

You can choose to test only specific parts of the web application (such as selected modules), or allow us to assess the entire application.

/0 5

The test can be performed as a black box assessment (simulating an external attacker without prior knowledge) or as a gray box assessment (with partial insight into internal logic and access to information provided by your development or IT team).

/0 6

You have full visibility into our testing activity through your logs, as the exact date and time of testing are known.

/0 7

Assurance that no harm will be done to your production systems. If preferred, we can perform the test on a replica of your environment instead of the live system.

/0 8

A detailed report based on international standards, meeting the requirements of local regulators (especially the recommendations of the Czech National Cyber and Information Security Agency), including an executive summary and specific recommendations on how to improve your security posture.

Our quality standard

Not All Penetration Tests Are the Same

Many are limited to vulnerability scanning without simulating actual breaches or real-world exploitation scenarios
Most follow standardized procedures, but attackers think beyond what is defined by standard methodologies
Some providers highlight the discovery of globally impactful vulnerabilities, occasionally presenting them as 0-day findings

We assess vulnerabilities using the globally recognized FIRST CVSS scoring system, while also applying contextual and experience-based judgment
We do not focus solely on known vulnerabilities, but actively seek misconfigurations and non-standard practices that real attackers would likely exploit
We draw from experience gained through dozens of penetration tests we have performed across various industries

We go deep and aim to understand the root cause of each issue while also mapping the full exploitation path that an attacker could take

We follow strict ethical guidelines and never disclose identified vulnerabilities, even when classified as 0-day issues. While we have discovered dozens of such vulnerabilities, none have been publicly listed in CVE databases
