What My Clients Say
“We manufacture advanced rail equipment for global clients and needed ISO 9001 systems that could actually keep up. Jack helped us build and audit a quality system that works in practice, not just on paper. His calm, knowledgeable support has kept us on track through every internal audit and improvement cycle.”
K.C. Wong , Managing Director, EPDM
“Jack led our ISO 27001 implementation from scratch for our SaaS offering, then updated everything when the standard changed. He translated technical compliance into clear, scalable frameworks across the business. It’s rare to find someone who gets security, systems, and real-world operations the way Jack does.”
John Demelis , CTO, PERSUIT
“I’ve worked with Jack across multiple ISO-certified businesses over the past 30 years. His depth in both ISO 9001 and ISO 27001 shows. He brings structure, clarity, and practical systems that pass audits and actually work. Jack knows how to get small teams over the line without overwhelm. If you need someone who delivers, this is your guy.”
Alan Kohn , CISSP, CISA, AAIA, Lead Auditor
“Had a great experience with Jack. Process was easy and the turn around was fast. Would use again.”
Robert Koch
“Jack established clear structures and practical systems for our ISO 9001:2015 implementation, consistently exceeding expectations and enhancing our confidence in both the system and the audit process.”
Yvette Rose, AM Components
“UMISUS recently conducted our internal ISO 27001 audit and we were highly impressed by the professionalism, expertise and quality of service. Structured, timely and thorough. They provided clear, valuable insights throughout. We would strongly recommend UMISUS to any organisation seeking a trusted partner for ISO 27001 audit services.”
