Our History

Founding story of Cubro

How the company came to be?

Christian Ferenz (CEO):

I used to work as a reseller of monitoring boxes. During one of the business meetings, a customer asked me if I could provide him with a network TAP. The company had several monitoring tools but wanted to deploy a network TAP. He explained how this tool could help save the company’s IT costs.

At that point, there were not many vendors of network visibility tools. This was the starting point. I decided to grab that opportunity. Together with two of my colleagues (co-founders of the company), we created a Network TAP which the customer tested and after some changes decided to deploy in the company’s network. Those first TAPs which we made in 2003 are still deployed in the company’s network.

Our business idea is based on partnership with our customers. Opportunities started opening for us. We understood the challenges related to network visibility and through our technical expertise, we started producing more advanced tools like the network packet brokers and probes. After literally producing our first product in a garage, our products are installed in several major CSPs and enterprises all over the world.

What motivates us and our team each day?

Sascha Naunovic (CFO):

We started the company with four employees and since the beginning we were passionate about the business. Since our launch, our core objective has been to meet the customers’ demands.

The motivation comes from the challenges we face in delivering what the customer asks for. We compete with some big players but over the years our customer base has grown steadily and we are proud of our growth rate.

Herbert Etlinger (Head of Product & Solution Engineering):

Our collaborative team environment is one of our biggest advantages.

We maintain a powerful team spirit at work and effectively communicate the goals of the company.

What is our culture?

Christian Ferenz (CEO):

My biggest satisfaction is seeing smiling faces each morning at work. In our office, we celebrate success and learn from the failures. Each department has a key role in delivering the best experience to the customer and we empower our employees to achieve this goal. We are a transparent company and value our human resources. Our open-door policy at work encourages our staff to share ideas that help us grow.

Gabriel Guriencu (CTO-Hardware Development):

Since we are a small medium sized company, we benefit from being customer centric and innovation driven. Our customers can reach us easily and get personalized support from real people instead of a computerized machine. We make speedy decisions and implement them at a faster pace. The key to unlocking our growth was providing the right solution to the customer and value for money. We think on a bigger scale and constantly focus on making technologically improved products.
