    This #RSAC, there was one recurring question: Where in the world is John Kindervag? 🌍 Answer: everywhere. Illumio Chief Evangelist—and the Godfather of Zero Trust—was seemingly in multiple places at once: 🎤 Numerous speaking sessions (solo and alongside leaders from NVIDIA and CVS Health) 🧠 An exclusive 30‑person Birds of a Feather 🏟️ Multiple booth talks with Deloitte and other partners 🎥 And a nonstop stream of interviews If RSAC had a frequent‑speaker miles program, John would’ve broken it. Huge thanks, John—now we officially prescribe at least one day off. 😉

    At RSAC 2026, one message was clear: AI is accelerating everything, including attacks. As the time between vulnerability discovery and exploitation shrinks, security teams are facing a hard reality. Prevention alone is no longer enough. In his latest Zero Trust Hub briefing, Gary Barlet shares three takeaways from RSAC, including: - Containment is becoming just as critical as detection - Zero Trust is shifting from theory to execution - Segmentation is now being measured by impact, not architecture Read how Zero Trust helps limit blast radius when breaches happen faster than ever. 👉🏼 hub.illumio.com

    We spend a lot of time talking about cyber threats. But what if the real vulnerability isn’t technical at all? This week on The Segment, we’re joined by Tim Kromphardt, a threat researcher at Proofpoint who does something most of us wouldn’t dare: He talks directly to scammers. From business email compromise to “pig-butchering” scams, Tim shares what he’s learned from engaging with threat actors — and why modern attacks are less about breaking systems and more about manipulating trust. A few takeaways: • Why social engineering hasn’t fundamentally changed • How scams operate like highly organized businesses • Why even experienced professionals can fall victim “There’s not some new, novel way to convince someone… there’s tried and true methods.” If you think cybersecurity is just a technology problem, this episode might change your mind. 🎧 Listen here: https://bit.ly/4s4deMk

    Thank you #MISA for hosting an Illumio demo at the #MicrosoftSecurity booth at #RSAC. And thank you to Jeff Stauffer and Aditya Krishnan for demoing how Illumio and Microsoft provide a more secure zero trust approach that helps organizations limit lateral movement, reduce breach impact, and strengthen cyber resilience across hybrid and multicloud environments. Huge thanks to Maria Thomson for the incredible MISA support!

    RSAC isn’t about seeing every booth anymore. It’s about the conversations that matter. In a new briefing, Zero Trust creator John Kindervag shares what he expects to define RSAC 2026, from AI hype versus real outcomes to why Zero Trust discussions have shifted from “why” to “when.” AI will be everywhere again this year. The real question is whether it actually delivers value or just attention. At the same time, organizations are no longer debating Zero Trust. They are racing to implement it as AI expands data flows and attack surfaces. If you’re heading to RSAC, this is a must-read perspective on how to cut through the noise and focus on what actually works. Read the full briefing here: hub.illumio.com
