Our ethical hackers will test your measures in a realistic and effective way

Safety is about certainties
For every organization, it is important to ensure that the security and continuity of your IT environment are properly safeguarded. In this respect, it does not matter whether you manage IT/OT yourself or have outsourced it.
Our ethical hackers test your cybersecurity in practice. Together, we will determine which approach is most suitable for your situation. That can be a pentest are, but also red teaming is one of the options.
What suits my organization?
Pentesting
With a pentest, or full penetration test, our ethical hackers manually and automatically search for vulnerabilities in your IT environment. By proactively detecting these, both the business continuity and the business reputation of your organization are monitored. There are different types of pentests. Depending on the purpose, it will be determined which type of test is most suitable.
Red Teaming
At Red Teaming, we test the effectiveness of your security measures. We do this with realistic attack scenarios, where our ethical hackers act as cybercriminals. During such an attack, we test your organization's detection and response capacity and resilience. In this way, we provide insight into where vulnerabilities are and where improvement is possible.
Good preparation is essential
A pentest assesses the security of one or more information systems by providing insight into the path that a malicious actor would follow.
Red teaming goes further. Red teaming includes the technical component, but additionally tests the gaps in detection, response and processes.
Offensive security has various test methods. Although red teaming is in many ways similar to pentesting, there are still important differences. The biggest difference is that pentesting tests whether there are vulnerabilities in your system; in red teaming, we mainly check whether the detection measures are in order.
Both methods, of course, also take into account factors such as the business context and the applicable laws and regulations.

We help you assess the measures taken.
Our ethical hackers can help you by testing and improving your organization's cybersecurity in practice. Want to know more about Red Teaming or pen testing? Then contact us.
