About Me


Having worked for over 40 years in the industry as an employee of one of the leading solution providers of ICS I have the privilege of  having acquired knowledge not easily accessible to people that have not worked on the vendor or asset-owner side. Working in an environment with a global view on thousands of ICS, participating in many projects is a great benefit for ones learning curve. I am very grateful to all those colleagues and asset owners willing to share their knowledge and discussing the many challenges an automation system offers during the many projects.

Having said all this, another objective is to remain vendor neutral and protect the intellectual property of my employer, which isn’t always easy and sometimes even requires to come-up with new names to avoid the use vendor specific terminology. I might sometimes fail caused by ignorance but it is my objective to avoid vendor specific terms where not relevant.

I have active certificates for CISM, CRISC, CISSP, CISSP-ISSAP and passed various exams on network and security courses from SANS, Cisco, and Microsoft.

Apart from this I am a US patent holder in the area of cyber security risk (US 9,800,604 B2)
