Learn more about our Pentest service below.
Penetration testing (Pentest) uses the same techniques and tactics employed by hackers to find vulnerabilities in systems and infrastructure by simulating real attacks. The goal is to identify vulnerabilities that, if exploited by malicious actors, could compromise your information. The result of the analysis is a report containing all identified vulnerabilities and suggestions for correction or mitigation.
A pentester is an experienced offensive security professional with a real attacker mindset and strong manual testing capabilities. Pentesters simulate real-world attacks using a wide range of methodologies, tools, and techniques to identify vulnerabilities before malicious actors can exploit them.
In a Black Box Penetration Test, the pentester has minimal information about the target. They must explore the application to obtain as much information as possible.
In Grey Box Pentesting, the pentester has a standard access credential to the system, simulating the access of a normal, malicious user.
In a whitebox pentesting test, the pentester has administrator access credentials, meaning they have full access to the application or the network.
A Pentest should be used when your company needs to evaluate how systems, applications, and infrastructure can be exploited in real-world attack scenarios.
It is especially relevant when there is a risk of data breaches, unauthorized access, privilege escalation, or exposure of sensitive information due to technical vulnerabilities.
This type of assessment helps identify exploitable weaknesses, validate security controls, and understand how attackers could compromise your environment before it happens in a real incident.
This service is commonly used to assess critical systems and applications within the organization, such as:
Web
API
Mobile
Android
iOS
Executables
Windows
Linux
These targets are often prioritized because vulnerabilities in these components can lead to unauthorized access, data exposure, system compromise, and broader impact across business operations.

White-label delivery for partners and consultancies
Unlike automated vulnerability scanners, our penetration testing is performed manually by experienced security professionals simulating real-world attack scenarios.
Our penetration testing methodology is based on real-world offensive security practices and manual testing performed by experienced professionals. Each engagement begins with scope definition and reconnaissance to understand the target environment, followed by vulnerability identification and controlled exploitation to validate real risks.
When applicable, we also perform post-exploitation activities to assess potential impact, lateral movement, and privilege escalation scenarios. All findings are carefully documented, risk-prioritized, and delivered with clear, actionable remediation guidance. After remediation, we provide a validation retest to confirm that identified vulnerabilities have been properly addressed and the security posture has been effectively improved.

In addition to the technical report, BRZTEC provides an executive report designed for management and decision-makers. This report summarizes the overall security posture, highlights the most critical risks, and explains business impact in a clear and non-technical manner. It also includes risk prioritization, high-level recommendations, and strategic guidance to support informed decision-making and improve the organization's overall security posture.

Conclusion and Next Steps
We support our clients throughout the remediation process by working closely with their teams to address identified vulnerabilities. This includes reviewing application architecture, participating in technical meetings, recommending best practices, and validating proposed fixes. We also help identify potential bypasses or gaps in remediation efforts, ensuring that vulnerabilities are effectively mitigated and the overall security posture is improved.
All our clients are entitled to complimentary retests until the identified vulnerabilities have been properly remediated. The retest can be scheduled in coordination with the project manager and will focus exclusively on validating the effectiveness of the implemented fixes. The purpose of the retest is not to perform a new penetration test, but to confirm that the remediation actions were correctly applied and that the vulnerabilities have been effectively addressed.

To request a Penetration Test (Pentest) quote, you need to define the target or targets that need to be tested. Targets can be application URLs, mobile applications, an API, an executable, etc. The important thing is always to prioritize the crown jewels, that is, those applications that are most important to your business, and to perform a full Penetration Test at least once a year.
01 - Black Box - An unknown party or competitor attacking me
In this scenario, which corresponds to a Black Box Pentest, we only need the URL(s) of the applications that could be targeted by an attacker. Here we simulate an attack by a hacker who discovered your application or was hired to carry out attacks against your application.
02 - Grey Box - A client/collaborator/supplier attacking me
In this scenario, which corresponds to a Grey Box Pentest, we need 01 or 02 access credentials for the applications that could be targeted by an attacker with the most common access profiles. In applications that allow onboarding (self-registration), it will not be necessary to create a credential, as our team will perform the self-registration in your application. In this scenario, we will simulate a malicious client, supplier, or hacker who obtained a credential with these access profiles.
03 - White Box - An IT administrator attacking me
In this scenario, which corresponds to a White Box Penetration Test, we need credentials from an application administrator, meaning someone with full access to the application, including permissions to create users, change access profiles, modify application settings, and other permissions. This allows us to identify the potential damage that could occur if a privileged employee or a hacker were to obtain these credentials.
We always recommend testing in a staging environment if that environment is a replica of the production environment. However, if this is not possible, our penetration tests can be performed in the production environment, outside of business hours, entirely manually and under the client's supervision.
If any system becomes unavailable during the penetration test, our team executes the activation protocol that will be configured during the planning phase. This allows us to restore the system as quickly as possible.
The execution time of a penetration test is relative, as it depends on the number of targets to be tested. A simple penetration test can take 2 to 3 weeks, while complex penetration tests can take 2, 3, or 6 months.
