Pentest in 3 steps

A pentest at CyberAnt involves three steps. That way you always know where you stand.

Step 1: Inventory

A pentest starts with an intake. Together we determine what you need and what the next step looks like.

Step 2: Automatisation

We believe in automation. It allows us to check for all known vulnerabilities checked in our (self-developed) tooling without forgetting one, in a fraction of the time it would otherwise take. And the great thing is, after the pentest, you can repeat this step with little cost so that you stay informed about the security of your application after the pentest.

Step 3: Manual examination

CyberAnt’s ethical hackers are unique in their knowledge and skills. They are able to find vulnerabilities that no one has ever found before, even within your network or custom application. Because all known vulnerabilities have already been found in step 2, the security specialist can focus as much as possible on finding the new vulnerabilities that are most dangerous for your company.

“The pentest report helped us understand the risks we were running and the potential for abuse.”

How is it tested?

A pentest investigation has 3 phases: blackbox, graybox and whitebox. We are happy to explain the difference.


Research In the blackbox phase, the starting point is that the attacker knows nothing yet. An example is a hacker who visits your website or network for the first time. In the blackbox phase we look at what an attacker can find out and whether there are any vulnerabilities that can be exploited directly.

The results of the automated part of the Website security check or the network security audit often form a solid foundation for this phase, leaving only but it is necessary to look at the custom components.

Greybox research

In the greybox phase, the attacker knows more. Think, for example, of one of your customers who logs in to your customer portal. The attacker has little or no real “inside information” at this point, but understands the context of the application and has limited access to it.

The blackbox and greybox phase combined form a good picture of what a hacker can achieve with limited time.

Whitebox research

In this phase, the attacker knows almost everything. There are admin accounts available, questions can be asked to the developer and sometimes even source code is available. If all goes well, an attacker will never get that far in real life, but this phase helps the investigator to save time. As a rule, a pentest is always timeboxed, while an attacker has unlimited time. For that reason, we often take a shortcut using the inside information.

Frequently asked questions about the pentest


What is a pentest?

In a pentest, a security specialist tries to break into a website. “Pentest” is an abbreviation of “penetration test”. A pentest assesses the security of a website or computer system, so that you know whether the security also works in practice. This is also known as ‘ethical hacking’. At the end of the test you will receive a report and a presentation, so that you know exactly where the weaknesses lie, but also what the strengths are.

How does a pentest work?

Prior to the pentest, the security specialist will contact you to agree exactly what will be tested, how long the test will take and in which environment the test will take place. Often a test takes place in a test environment that resembles the production environment as much as possible. Within the predefined frameworks, the specialist will then pull out all the stops to enter. We also note points that do not directly lead to a data breach, but where security can be further increased.

Who is a pentest for?

Pentests are performed in online environments that really shouldn’t be hacked. It has long since ceased to be the case that only banks have pentests performed. Nowadays, many companies have their customer portals, apps and sometimes even entire computer networks subjected to a pentest. Beforehand, it is checked whether a pentest is indeed the most effective solution. Sometimes it is wiser to start with, for example, vulnerability management, a Website security check or training for the developers or administrators . With our free Quickscan you immediately get an indication of the security of your website.

Is it possible to do a Website security check first?

Yes, the Website security check is a good first step to do when you want to have a web application or website tested. When you later have a pentest performed, we use the results from the Website security check as input for the pen test so that time (and therefore money) can be saved on the quotation.
