About Me

Allan van Leeuwen

I am a strong people manager who excels at establishing and improving structure and team cohesion. I am passionate about guiding, motivating, coaching, and stimulating employees. With an extensive background in the security sector, I bring the knowledge and experience necessary to elevate a Security Operations Center (SOC) to the next level of maturity.

Throughout my career at companies like KPN, Nomios, Motiv ICT Security, ABN-AMRO, and Aramco, I've transformed security teams, implemented strategic frameworks, and developed innovative educational tools. I have a proven track record of growing teams, optimizing alert management, and continuously improving security monitoring services.

My most notable achievement was transforming a Security Operations Center from 5 to 50 employees in 5 years while implementing MAGMA and SOC-CMM frameworks for optimized alert management. I'm also passionate about developing educational tools for red teaming and creating custom security solutions.
