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.
