OTT Europe

About OTT Europe

OTT was founded in 2009 under the name Optimis and since then we have been providing full training support to ISA Europe. While we have contracted with ISA through its ISA Europe office for many years, we will now be offering ISA training as an ISA Authorized Training Reseller under our new name OTT. OTT is an independent company managed by Esther Vervoort and Bram van der Klooster and is located in Eindhoven-The Netherlands. Recognizing the growing demand for specialized training in operational technology, OTT has taken a bold step forward by establishing this company. This entity offers high-quality training programs tailored to the needs of today’s dynamic industrial landscape. Our ISA certified trainers and ISA/IEC62443 Subject Matter Experts have trained more than 10,000 students in recent years.
