Hi everyone, I’m Dimitri, but most colleagues and friends call me Dimi. I’m passionate about everything related to hacking, security, and technology. My fascination with hacking started back in 1995 after watching the movie Hackers, and ever since, I’ve been exploring, building, breaking, and learning.
Dimitri Verhoeven – Penetration Tester
Penetration Tester
I joined tSF in December 2025 as a Penetration tester. Before that, I gained 10 years of experience as a Network Administrator and R&D Specialist, spent several years self-employed, and worked for 5 years as a triager.
At tSF, I’m focusing partly on web application security and partly on infrastructure testing. My journey toward becoming a pentester was a natural progression. I’ve been deeply involved in security, hacking, and bug bounty hunting from a young age. I am eager to take on new challenges and expand my knowledge across different areas of the hacking landscape.
In the role as a pentester you need a strong willingness to continuously learn, the ability to think outside the box, and have a deep understanding of how systems and technologies work. What I appreciate most about working at tSF is the open communication, the team spirit, and being surrounded by colleagues who share similar interests and are always willing to learn from one another.
Outside of work, I exercise some sports like tennis, golf and surfing to stay active. I also enjoy working around the house and building things. In between all of that, I spend quality time with my family and experiment with 3D printing and creative tech projects.
Looking ahead, my goal is to continue growing, especially in infrastructure testing, red teaming and physical security.
