Pentest of Networks
The exact course of a network penetration test depends heavily on the specific services in an IT infrastructure. Nevertheless, the approach of a real attacker can be generalized. For example, the BSI (german Federal Office for Information Security) lists modules describing various intrusion attempts in its implementation concept for penetration tests. Based on the information from the BSI, the test method used by binsec GmbH is roughly divided into the 3 following test phases for a network or IT infrastructure pentest:
Identification of attack surface
- Evaluation of publicly available data
- Identification of services based on open ports via TCP and UDP
- Verification that access controls such as firewalls or network segmentation are in place
Checking for vulnerabilities
- Checking the patch statuses and the software versions used to ensure that they are up-to-date
- Checking the access restrictions of services
- Checking whether services have been set up according to security best practices
Exploitation
- Development of proof of concepts to exploit identified vulnerabilities
- Privilege escalation through the chaining of vulnerabilities

Approach: Standard-Compliant & Reproducible
A penetration test is a structured attack on IT systems or applications to identify potential vulnerabilities. It uses the same tools and techniques that real attackers would use to break into a system. Thus, a penetration test is not an automated vulnerability scan. On the contrary, a penetration test as a service is always a combination of using security tools and conducting manual tests to uncover vulnerabilities. While a real attacker only needs to find and exploit a single vulnerability, a penetration tester checks all relevant attack vectors.
Having a structured approach is one of the most important factors. For this purpose, we use our own platform PTDoc®, a specialized pentest documentation tool that logs all manual testing steps in full compliance with all relevant security standards and translates them into a clear, reproducible report for you. Since this tool significantly reduces the overhead of report generation, it allows us to focus entirely on our core mission as pentesters: identifying and analyzing critical security flaws. This is particularly relevant when conducting a network penetration test. Our approach is based on all relevant standards and publications.
How We Work During Network Penetration Tests
From Planning to Re-Testing
Preparations
We coordinate the technical and organisational framework for the penetration test, communication channels, points of contact and testing windows. Depending on the project, this is done through a kick-off meeting or a brief exchange via e-mail. Where required, the client provides relevant technical documentation and access to the systems within scope.
Conducting
The penetration test is performed using a structured and risk-oriented assessment approach that combines automated analysis techniques with extensive manual testing. The specific test cases and assessment procedures depend on the actual conditions, technologies and attack surface encountered within the target environment.
Reporting
After the assessment, we prepare a detailed report including an executive summary, risk ratings, technical details and remediation recommendations. Findings are documented in a clear and reproducible manner and critical issues are communicated immediately during the engagement if required.
Debriefing
We are happy to review the findings and recommendations together with your team. During the debriefing, we explain technical details, potential impacts and remediation priorities, while answering questions and discussing next steps.
Re-Testing
After remediation, we verify whether the identified findings have been successfully resolved and update the report accordingly. Re-testing is generally included for remote assessments and provides assurance that the implemented measures are effective.

Planning a penetration test always requires a careful balance between the time invested in testing and the financial framework to achieve a reasonable price-performance ratio. Successful pentests are characterized by a precise balance between these factors, as this is the only way to guarantee a reliable review of all relevant attack vectors. The time required depends on the size and complexity of the scope. While testing smaller infrastructures can often be completed in a few days, reviewing extensive or globally distributed corporate networks can take several weeks.
To provide a tailored pentest offer, we require initial information regarding the systems and applications to be examined, allowing us to accurately assess the target environment. If you require an infrastructure penetration test, we will need the relevant network addresses in advance. In this case, we will first perform a non-invasive network scan to conduct an initial scoping analysis, which forms the basis for your detailed quote.

binsec GmbH: Professional Penetration Testing
Network Penetration Test
As a specialized provider for penetration testing, binsec GmbH focuses specifically on your Network Penetration Test.
Talk directly to the executing experts instead of sales consultants. Better pentesting. No nonsense. As a dedicated penetration testing firm, we do things differently: We do not sell automated vulnerability scans as a true pentest, focusing instead on manual analysis of complex business logic flaws. Looking for a professionally conducted penetration test? Let's discuss your project.

Frequently Asked Questions
It is difficult to give an generalized answer to this question, since the toolset used basically depends on the respective test object. Of course, we use tools such as nmap to check IT infrastructures or the Burp Suite Professional in the case of web applications.
However, we believe that publishing a tool list is mere window dressing, as each target system should be tested individually. However, you are welcome to ask us about the tools we used after the pentest.
Hosting critical business applications on a cloud provider such as Amazon AWS, Microsoft Azure, Google Cloud or Hetzner Cloud is becoming increasingly common.
Of course we perform penetration tests for applications hosted in the cloud. This also applies to penetration testing of cloud-based IT infrastructures, provided that the virtual machines are not managed directly by the cloud provider.
We perform penetration tests for almost any IT environment, system, application or network – right down to protocol fuzzing. Only the analysis of hardware chips under a microscope is something we leave to others.
