Is the "AI Elixir" finally here for Service Providers?In this episode of ZKast, Zeus Kerravala sits down with Simon Dumbleton, CTO of Europe for World Wide Technology (WWT), from Mobile World Congress 2026 in Barcelona.As the European telecom landscape faces unique challenges—from data sovereignty and strict regulation to the "Post-Quantum Cryptography" migration—service providers are looking for a pragmatic path to modernization. Simon and Zeus dive deep into how operators are moving past AI experimentation to find real-world ROI in the NOC and beyond.🔍 Key Topics Covered:The Sovereignty Shift: Why Europe is taking a pragmatic approach to "Secure by Design" infrastructure.Monetizing the Network: Moving beyond "unlimited data" to AI inference-as-a-service.Lessons from 5G to 6G: Why 6G needs to "cut the cord" on backwards compatibility to truly innovate.The AI Proving Ground: How WWT’s Advanced Technology Center (ATC) uses digital twins to de-risk massive telco migrations.Network Optimization: Using AI to clean up "human-unreadable" legacy configurations.🚀 About World Wide Technology (WWT)WWT is one of the world’s largest systems innovators, helping organizations bridge the gap between complex technology and tangible business outcomes. Through their AI Proving Ground, they allow service providers to test-drive massive infrastructure shifts in a controlled environment before hitting the live network.Connect with WWT:Website: wwt.com#MWC26 #Telecom #AI #6G #DataSovereignty #WWT #DigitalTransformation #ZKast

But did you know those same rules apply to protecting your data?In this episode of ZKast Zeus Kerravala sits down with Chris Burrell from Zscaler at the iconic Oracle Park. From the McCovey Cove suites to the pitcher's mound, they break down how the fundamentals of the diamond mirror the core principles of a Zero Trust architecture.🕒 Timestamps:00:00 – Intro: Preseason Vibes at Oracle Park00:45 – Rule #1: Keep Your Eye on the Runner (Continuous Authentication)01:30 – Rule #2: Don’t Let the Winning Run Get to Second (Micro-segmentation)02:15 – Rule #3: Tie Goes to the Runner (Assume the Breach)03:00 – Rule #4: Don’t Walk the Lead-off (Least Privilege Access)03:45 – Rule #5: Paying Dues in the Minors (Device Posture & Checking the Ball)04:30 – The Future of the Game: AI, ABS (Automated Balls & Strikes), and Go-Ahead Entry⚾ Key Takeaways:Blast Radius: Just like keeping a runner out of scoring position, micro-segmentation limits how much damage a threat can do once inside the "stadium."Device Posture: If an umpire checks a pitcher for pine tar, your security system should be checking your devices for "sticky" vulnerabilities.Innovation: A look at how MLB is leading the way in tech with AI-driven officiating and biometric entry.About ZK Research: ZK Research provides a mix of tactical and strategic advice to help organizations navigate the complex landscape of networking and security.About Zscaler: Zscaler accelerates digital transformation so customers can be more agile, efficient, resilient, and secure.#RSA2026 #ZeroTrust #CyberSecurity #SFGiants #Zscaler #BaseballTech #ZKResearch #CloudSecurity @SFGiants@ZscalerInc @MLB
