From pen testing to clear reporting!

Step 1: intake

During the intake, we discuss the scope components and attack scenarios of the pen test. An NFIR ethical hacker will also be present during the intake.
The intake is an important starting point because we would like to test all components within the scope of the pen test and identify all vulnerabilities. Based on the intake, we provide an hourly estimate and proposal.

Step 2: Proposal and agreements

After you receive the hours estimate and proposal, we will be happy to discuss your questions.
In consultation, we will find a suitable time to perform the pen test.

Step 3. implementation

During the pen test, we will keep you updated on progress and vulnerabilities.
Critical vulnerabilities are reported immediately so that they can be fixed as soon as possible.

Step 4: Results

The vulnerabilities are documented in a clear and complete pen testing report. A standard part of our pentest services is to explain the findings following the delivered pentest report.
This explanation is greatly appreciated by our clients.

Step 5: Perfecting

Thanks to the clear insights, you are going to mitigate the vulnerabilities.
If desired, after the vulnerabilities have been mitigated, we can arrange for a retest. Based on this retest, you will receive a new pen test report and have confirmation that the vulnerabilities have actually been fixed

Why conduct a pen test at your organization or company?

By performing a pen test at NFIR, you will discover weaknesses in your IT/OT environments. Our ethical hackers identify vulnerabilities and provide insight into the effectiveness of your security measures, as well as potential consequences if misused.

The importance of an enterprise network pen test

The main reasons to perform a proper pen test on the network are:

  1. Identify vulnerabilities and risks:
    Receive a summary report of the vulnerabilities and risks present within your infrastructure and applications.
  2. Building trust:
    Customers, shareholders and other stakeholders expect their information to be secure. A pen test provides insight into the level of security.
  3. Comply with standards and legislation:
    Various standards and legislations such as the AVG, BIO, ENSIA and ISO, require taking appropriate security measures. A pentest helps you meet these requirements.
  4. Continuous improvement of security:
    The results of the pentest can be used to improve and optimize your information security.

Attack scenarios; Black Box pentest, Grey Box pentest and White Box Pentest.

Perform a pen test from different perspectives, with the result depending (in part) on the chosen attack perspective. During an intake meeting, we jointly determine the scope of the pen test and advise our security specialists/ethical hackers on how to perform the most valuable pen test for your organization.

Black box pen testing hacker organization applications security information

Black Box pentest

In a Black Box Pentest attack scenario, minimal information is provided in advance by the client. Ethical hackers will operate as "outsiders" without inside information. Pentesters use various techniques, including Open Source Intelligence (OSINT) to discover vulnerabilities.

Grey box pen testing risk hackers automated network penetration test the netherlands

Grey Box Pentest

A Grey Box Pentest attack scenario sits between a Black and White box. There is "limited" sharing of information used to investigate an environment. The ethical hackers will use a user account to examine the infrastructure or application.

white box pentesting ethical hardware vulnerability pentester security audit computer systems

White Box Pentest

In a White Box Pentest attack scenario (also known as Crystal box), all information is provided in advance to search for vulnerabilities in a targeted manner. Consider the information that is also requested in Grey Box pentesting. In addition, source code, log files and server access are used. In addition, the ability to set up your own test environment can be used.

What clients have to say

Frequently asked questions about performing pen testing


A pen test, penetration test, or penetration test, is a simulated cyber attack on a system, network, or application to identify and exploit security weaknesses. This helps organizations evaluate and improve their security measures by exposing potential threats and vulnerabilities before malicious actors do.

An enterprise network pen test is an in-depth analysis of your network security. NFIR's experts identify and fix vulnerabilities to protect your corporate network from potential attacks.

Depending on the size of the job, a careful assessment is made as to whether multiple people should be put on a pentest to reduce the length of the job. The duration of a pentest can vary depending on the environment being tested and the complexity of the attack scenarios being used. Generally, a pentest covers a period of 2 to 4 weeks. This period includes not only the execution of the test itself, but also the preparation, analysis and explanation of the final report.

A pentest (penetration test) is necessary because companies are often unaware of vulnerabilities in their network and systems. It is a controlled and authorized attempt to evaluate security through a simulated attack. The main reasons for a pentest include vulnerability identification, risk management, regulatory compliance, evaluation of new applications and changes, protection of customer data, and building trust with customers and stakeholders. Conducting regular pentests is essential to improve security and prepare for potential attacks.

  • For example, a pentest is useful to:
    Assessing your current situation for vulnerabilities.
  • Detect vulnerabilities before the release of new applications.
  • Check weaknesses after changes to infrastructure or applications.
  • Comply with corporate policies, standards and/or legislation that require periodic security assessments.
  • Test your Cybersecurity maturity against the detection methods you have implemented.

When performing a pentest, various international standards and methodologies are used to discover and classify vulnerabilities.

Some of the key standards applicable to the assignment include:

By using these standards, a pentest can be performed in a structured and thorough manner, and the results can be reported in a clear and comparable way.

Our pentesters have a large amount of experience, a lot of creativity and up-to-date expertise. The NFIR pentesters have followed relevant training courses and obtained certifications such as OSCP. In addition, they have all received chief of police approval and signed confidentiality agreements.

A Black Box pentest means that no information about the environment is shared with the pen testers beforehand. With a pentest based on the White Box principle, all information about the environment is shared in advance. If you are having a pentest performed for the first time and want to get an overall picture of your security, it is useful to have a Black Box pen test performed.
