Phil van der Linden

I had pleasure of working with Chris during his time in the Proficio SOC. Chris is very knowledgable about cybersecurity and vulnerability assessment/management. He was always willing to do cross-training and is excellent at instructing both colleagues and customers alike. I think his combination of people-skills and technical skills will take him far with any organization he is a part of.
