Pleasure in the job puts perfection in the work

- as Aristoteles said once. We Sentorians, on the other hand, do not believe that you can ever achieve perfection.  We know that there is no way to build systems, apps or networks that are 100% secure or create a magical solution that works for everyone to deal with the threats posed by cybercriminals. Why? The digital landscapes that we all move in are changing all the time and new cyberthreats are constantly being developed.

Passion for security

Our team consists of individuals who are united in their common interest in security. Since the conditions for security change all the time, we Sentorians are determined to never stop growing and learning.

In order to do that, we invest in training, specialisations, and not least, creating a corporate culture where no one is expected to be perfect, but where everyone is expected to have a strong drive to fight the cybercrimaae of today and tomorrow. As evidence of the long-term efforts, we are also certified by Great Place to Work for the sixth year in a row.

As the Head of Marketing, Tomas is responsible for Sentor's communication. Before Thomas joined Sentor, he spent a few years as a digital strategist, helping companies reach the top of internet search results.
