Thijs Stuurman is a Lead Security Engineer with 11 years of hands-on experience securing complex Linux, Windows and Unix environments for large Dutch organizations. He combines deep systems and network expertise—iptables, Juniper firewalls, SIEMs like QRadar, and anti-DDoS tooling—with practical offensive skills in penetration testing and incident analysis using Metasploit, Nessus/OpenVAS, Wireshark and tcpdump. At Talpa Network he moved from security testing into a leadership role, drawing on prior positions at KPN and Nxs to design auditable, standards-driven security programs (ISO 27001, PCI-DSS, NEN 7510). Comfortable scripting and building tooling in Python, Bash and C/C++, he bridges development and operations to harden services from Apache/Tomcat to cloud platforms (AWS, Google Cloud). Colleagues rely on him for pragmatic remediation plans and for translating compliance requirements into technical controls. Based in Zaandijk, he pairs formal IT education with a bias for practical automation and measurable security outcomes.
