Hi, I'm Marcus Bakker, an IT security professional with 15 years of experience in cyber defense. I started my career in consulting at KPMG and later worked in enterprise security at ING, where I learned to operate in complex environments.
I help organizations validate attacker behavior in their environment, understand how defenses perform in practice, and identify the improvements that matter most. My work combines cyber defense, detection engineering, and security automation, with a focus on getting things done — so initiatives move from plans to execution.
I work hands-on when needed with security teams and stakeholders, translating technical details into clear priorities and actionable improvements. I regularly act as a technical project lead, aligning teams and stakeholders and supporting changes from idea to implementation.
If you're looking for practical cyber defense with a strong focus on results, I'd be happy to connect.
