What Is Penetration Testing and Why Do You Need It?

In today’s digital age, cyber threats are becoming increasingly sophisticated. Whether you run a small business or manage a large organization, the security of your digital systems is no longer a luxury—it’s a necessity. In our previous blog posts, we’ve discussed new laws and directives designed to protect us, with a particular focus on the NIS2 directive, which is currently one of the most important. One of the best ways to assess your current standing and how resilient your system is to attacks is through penetration testing.

What Is Penetration Testing?

Imagine hiring a “good hacker” to try to break into your system—with your permission and for your benefit. That, in short, is penetration testing. Security experts attempt to uncover weaknesses in your IT system before real attackers do. The goal? To identify issues, fix them, and strengthen the security of your business.

What Does the Process Look Like?

You don’t need to know much about technology to understand how it works. Testing usually goes through several key phases:

Planning – You agree on what will be tested (e.g. website, email system, network…).
Data gathering – Experts analyze available information.
Simulated attacks – Testers try to “break into” the system just like a real attacker would.
Report and recommendations – You receive a clear, easy-to-read document listing the identified issues along with advice on how to fix them.

How Long Does the Testing Take?

It depends on the complexity of your system:

For a small company or application, 1–3 days is usually enough.
Larger companies with more complex infrastructure may require a week or more.
After the testing, an additional few days are needed to prepare the report and provide consultation.

At the end of the testing, you will receive concrete information:

A list of discovered vulnerabilities
Their severity
How someone could exploit them
How you can fix them
An overall security rating of the system

What is NIS2 and Why Is It Important?

Let’s recap: the NIS2 directive is a new European law that, starting in 2024, introduces stricter security requirements for organizations providing essential services—such as healthcare, energy, public administration, digital infrastructure, and others.

If your organization falls under the so-called “important” or “key entities” according to this directive, penetration testing is no longer just a recommendation—it’s mandatory.

NIS2 requires you to actively manage risks and demonstrate that you have taken concrete steps to strengthen cybersecurity. Regular testing of your systems is part of this process.

Penetration testing is not just a technical check—it’s a way to protect your business, your data, and your clients’ trust. Additionally, it can help you meet legal obligations, such as those imposed by the NIS2 directive.

If you want to learn more or arrange testing, contact the experts. It’s better to discover problems now, under controlled conditions, than later—under the pressure of a real attack.
