"Scott is an extremely thorough, trustworthy and knowledge consultant and auditor. I originally brought in Scott to replace the previous auditor, whose deliverables were not worthy of their name. He was able to quickly understand our organization, both technically and politically and immediately proved his worth. As an organization we were able to quickly shore up deficiencies and implement controls to help "future proof" our environment, saving us time and money! Scott is a true trusted advisor and SME in his field."

"After working with Scott Perry for three years of multiple complicated PKI Audits for our company, I continue to find Mr. Perry to be completely professional and consistent in his approach, methodologies, and conclusions."
