Senior🎓
Top SchoolJarno Baselier is a hands-on cybersecurity entrepreneur and senior systems engineer with nine years of focused experience in penetration testing, red teaming and network/system operations. As CEO of his own firm and a Cyber Security Specialist at Het Waterschapshuis, he blends practical offensive security skills (OSCP, OSEP, C|EH) with deep infrastructure knowledge (CCNA, MCSE) to secure complex public and private environments. He has a long track record running and scaling IT operations—from managing 70 servers and 400 workstations across distributed sites to building webshops and SEO-driven platforms as a longtime small-business owner. A pragmatic coach and communicator, he publishes technical blogs and video tutorials, translating advanced security concepts into practical guidance for peers and customers. Based in the Netherlands, he champions freedom and self-employment while constantly experimenting at the intersection of cybersecurity, networking and digital product development. An unusual strength is his combined background in internet marketing and hands-on pentesting, which helps him approach security with both technical rigor and user-focused pragmatism.
