S4 TESTIMONIALS

#S4×26 closed strong. Great to be back, connected with so many people and listen to thoughtful, experience‑driven conversations across OT Security.

From Main Stage to Prime Rooms, the agenda delivered solid perspectives.

What an honor to talk to the OT Jedis at S4! Thanks again for the invite Dale Peterson. This is such an impressive event, focused on a bunch of unsung heroes.

Nothing beats the energy of S4x26! Day 1 was a perfect blend of catching up with old friends, meeting new folks, and engaging in discussions that move the OT industry forward. Thanks again to Dale Peterson for always throwing such a great event!

Another S4 in the books. Closing in on my black lanyard.

Thank you Dale Peterson and team for putting in the work to make it happen.

Every year I walk into S4 expecting the same familiar faces and every year I’m grateful to see them. This community has a warmth to it that’s rare in any industry, let alone cybersecurity.

– Mark Hyman

S4x26 was fantastic. Great to see all my long time friends and awesome to meet so many new ones!

As always, Dale Peterson puts on one of the highest production shows available, without compromising on content quality AND quantity, all while creating a welcoming space for all to connect and advance OT/ICS cybersecurity. Everyone knows the presentations are stellar, but the networking and human vibe at this conference is simply unmatched anywhere else. So many (myself included) come away from S4 with our “we can do this – together” battery full.

I’m incredibly grateful to have attended #S4x26 as one of this year’s scholarship winners.
Huge thanks to Dale Peterson, the entire S4 team, and the Women in ICS Security program for creating such an impactful experience in my career.

I gained so much from the conversations I had throughout the week. The experiences, knowledge, and stories you shared added valuable context and enhanced my understanding in OT/ICS field.

Last week I landed in Miami for a very busy and excellent S4x26. Great to meet with so many familiar faces and to be greeted so warmly by many new ones. What a great community – looking forward to S4x27 in Tampa.

– Steven Webb

My first S4x26 ! Fantastic. The OT /ICS community creating the future – a more protected future.

Really a great event filled with collaboration, connecting, learning and deep thought. As the final session and panel is finishing up – a big thanks to Dale Peterson and the whole community – super productive.

First Time at S4… and What an Experience!!

Attending S4 for the first time was more than just a conference visit — it was a moment of alignment.

This year’s theme, “Connect and Create the Future,” couldn’t have been more relevant for the world of ICS/OT security we operate in.

In rooms filled with operators, researchers, asset owners, vendors, and practitioners, the conversations weren’t theoretical.
They were real. Raw. Technical. Practical.

– Divya Raj

Last week I experienced my first S4 conference and wow, what an amazing event! While the sessions were valuable and insightful, the networking among OT security professionals was unforgettable. Kudos to Dale Peterson and the entire planning team. Looking forward to seeing you all again next year!

– Monty M.

I had many great times of connection with many different people, and am touched by the sense of community that far surpasses just the OT/ICS security industry we work in. I saw (as always at S4) genuine connection, care, and a desire to encourage and support each other, from customers to partners to friends to even competitors.

– Josh Reber

Last week I had the opportunity to attend S4x26 in Miami Beach, my 7th S4 and nearly a decade of being part of this community.

Every year, it’s easy to see why this event is so special. It’s not just a conference, it’s the heartbeat of the OT/ICS security community. The conversations are honest, the debates are healthy and the relationships are real.

– Jeffrey Macre

And then… #S4x26. If you have never been, it’s hard to explain the level of intention and energy it takes to bring together this many OT/ICS cybersecurity leaders from across the world, in one place, for real, honest, technical dialogue. #S4x26 has become one of the most influential OT/ICS security gatherings globally, hosted in Miami South Beach.

– Denrich Sananda

For me, #S4x26 isn’t just another conference; it’s a homecoming. I’ve been attending for over 5 years, and it remains the highlight of my calendar. There’s nothing quite like the energy of reconnecting with old friends and sparking ideas with new ones in the OT security community in sunny Miami.

– Pia Capra

And then S4x26… honestly, it’s hard to put into words the kind of effort and energy it takes to bring together so many experts from across the world. Huge thank you to Dale Peterson for building something that creates this kind of space for the OT/ICS community.

– Pallavi Singh

I always liked S4 for addressing elephants in the room and this year didn’t disappoint.

Attention this year was less on new features and more on streamlining the core-ones. Good direction.

S4 Community and the atmosphere of honest thoughts exchange remains unique and amazing.

– Michal Paulski

Thanks to the S4 team for the platform, the vendor PoC gauntlet, and consistently creating space for the hard questions.

– Susan Peterson Sturm

Been a great 2 days at S4x26 Miami so far. In this modern boom of focus on OT cybersecurity the insights and innovations shared here are unquestionably the foundations of what will drive the IT/OT convergence and protect critical infrastructure and OT environments for years to come. Looking forward to what the rest of the week still holds!

– Joshua B Slauscius

This really is the standard-bearer summit for the OT/ICS security community. The quality of the practitioners, the rigor of the content, and the genuine sense of shared mission make this unlike anything else in our industry.

– James Winebrenner

S4 is one of the most genuine, high-signal conferences in cybersecurity.
Massive respect to the crew and community behind it.
Already looking forward to the next one.
