S4x26: Feb 23 – 26, 2026
In Miami South Beach
S4 is …
Optimistic … Forward Looking … Creative … Driving Change
Set free a conservative, slow moving, change resistant community to discover new ideas and come up with innovative ways to use these new ideas to deploy secure, resilient and better ICS. It’s 3-days on 3-stages of sessions for the advanced OT security pro and early adopters. S4 is much more than the sessions. You will be with 1,000+ of the best in world talent. Influencers. Creators. People who are pushing boundaries. And we have a lot of fun with parties and eclectic experiences. All this in a creative environment that is designed to break you out of your normal thought patterns.
The best way to understand how S4 is different is to come to the event. The second best way is to ask someone who has attended, obviously we are biased. S4 is not for everyone. If you are an early adopter, like to be on the leading edge, or enjoy hearing, considering and creating new ideas, then there is a good chance S4 will be a great event for you.

OnRamp Sessions At S4x25
At S4x18 we had ten OT security 101 sessions in a training track called the OnRamp. Those sessions are available online in a playlist on the S4 Events YouTube channel. If you are a video learner, I still believe they are the best way to get up to speed quickly on OT...
S4x25 Agenda V1.0 Is Up!
Version 1.0 of the S4x25 agenda is now posted. It has about 80% of the session titles and speakers posted four months prior to the event. In October and November we will be announcing the keynotes and fireside chats, adding session details, filling in a few more...
OT Security Book Store At S4x25
We've had book signings every year at S4 since Rob Lee's SCADA And Me and Thomas Rid's Cyber War Will Not Take Place at S4x14. Back then even a diligent collector would have a small bookshelf of OT & ICS Security books. Not anymore. There are many books of varying...
