About us

NVISO is a pure-play cyber security consulting firm, focused mainly on the Financial Sector, the Technology Sector, and Government & Critical Infrastructure. What makes us special, is our exclusive focus on Security, our customer dedication and our reputation for expertise. Built on values of Pride, Caring for our people, Breaking Barriers, and fostering a no-BS approach, our Mission is to be an innovative, trusted and respected security partner for our clients.

NVISO was founded in 2013 by five young security professionals with a dream: To build a home and a hub for cyber security experts, here in the heart of Europe.

A team built on strong values. A place that prioritizes personal growth and encourages everyone to innovate. A community of experts that strives to be the best at what they do. All working towards the mission of protecting European society from potentially devastating cyber attacks.

We certainly came a long way since 2013. From 5 people to more than 200 people. From our first office in an apartment in Brussels to having 5 offices in Belgium, Germany, Greece and Austria. From being an unknown challenger to being a reference in multiple fields in cyber security.

From following SANS courses ourselves to being the company with the most SANS authors in their ranks.

As we look towards the future, we remain committed to our core values of personal growth and innovation, as well as our mission.

We will continue to expand our team and reach, as well as seek out new ways to stay at the forefront of the industry. With a strong foundation and dedicated team, we are confident in our ability to tackle whatever challenges the future may bring.
