Junior Penetration Tester

Already experienced in the world of cyber security? New to it all, but genuinely interested? Well, at NVISO we might be looking for you and we’d love to have a chat!


It all starts with the mission: NVISO is here to protect European society from potentially devastating cyber attacks! This means we offer cyber security services to private and governmental organizations to help them better prepare for, prevent, detect and respond to cyber security incidents.

So what does this mean in practice? What do you actually do?

  • Defining the overall cyber security strategy (e.g. building out and delivering an awareness program)
  • Offensive security services such as red teaming and penetration testing
  • Building and securing cloud-native architectures
  • Emergency support such as incident response / forensics when organizations are breached
  • Managed services such as Managed Detection & Response and Vulnerability Management
  • Highly tailored / niche cyber security work in for example ICS environments

The list is not exhaustive and our very own NVISO Labs is continuously investigating new possible services or new ways to tackle the rapidly changing problems in cyber security!

As a proudly European company, we currently have offices in Belgium (Brussels) and Germany (Frankfurt and Munich). Technically, we are present in many more towns and cities, as our people often work from home too.

All of this is built on four fundamental values that define who we are: We are Proud, We Break Barriers, We Care and No BS!
