S4x25 is Feb 11 – 13
JW Marriott Tampa Water Street
We’re excited to move S4 to Tampa for 2025. The JW Marriott is bigger and newer. We won’t need to limit the number of attendees. We will have bigger spaces for S4 Stages, Birds of a Feather events, industry meetings and other activities. While we will miss the Welcome Party and Cabana Sessions, the S4 Big Party on Wednesday night will offer even more than those past two events. Tampa is different too. Different vibe; different opportunities; and different challenges. It’s a great canvas for S4.
Check out the S4x25 page for key dates, sponsor information and the latest updates.
We still like Miami South Beach and will back there at least one more time for S4x26 (23-26 February 2026).

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.
After a Covid caused cancellation of S4x21, S4 came roaring back with a record 800 attendees and warmth of spirit at S4x22. S4x23 in February sold out with 1,100 attendees, and this will be the attendee limit for S4x24. More important than the numbers were the percentage of new and diverse talent we are seeing and the spirit that has been maintained at S4 despite the growth from 40 people in a small room in 2007.
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.
