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. S4 is the place where you learn what will happen in the next 1 to 3 years and how you can be a part of it.
After a Covid caused cancellation of S4x21 and delay until April of S4x22, a record 800 of the best in world talent in the ICS security community came together in Miami South Beach for S4x22. S4x23 brings us to a new venue with many new opportunities to further improve the attendee experience and advance the S4 Create The Future Vision.

New Venue for S4x23
Loews Miami Beach



The home of S4 since 2016, the Fillmore Miami Beach, will be closed in 2023. We will miss the theater and stage, and we think we have an even better location … The Loews Miami Beach.
- It is in the same area of South Beach, 16th and Collins, two blocks from the Surfcomber.
- It is large and can house the growing event.
- It is beautiful. Since this is a not a historic building, it has been updated to be larger, more modern and more luxurious. And we got an amazing rate for you.
- There is plenty of room for the three stages plus additional rooms for sponsors, special events, Pwn2Own and other things.
- One of the biggest complaints we received from S4x20 is the distance between stages. The Loews addresses this as all three stages are within a 15 second walk of each other.
- They have great amenities: pool, ocean activities, spa, fitness room, world class seafood restaurant, and a kids program if you bring the family.
