The SCADA Security Scientific Symposium (S4) began in Sunny Isles, Florida in January 2007 as a two-day event with ~40 attendees. The latest event, S4x20, was 3-days, on 3-stages and multiple parties/social events in Miami South Beach, and it had over 700 attendees.
In addition to the South Florida event in January, we held two S4xEurope events in Vienna, Austria and three S4xJapan events in Tokyo, Japan. In 2017 we decided to focus solely on the event in Miami South Beach that draws the largest crowd and best talent of any ICS security event. The 14 years of S4 have generated a ton of content, and more importantly sessions and connections that helped Create The Future of OT and ICS Security. We are now digging through the archives and are creating pages for past events. This is a work in progress.
