Assume Breach, Build Trust: Zero Trust Lessons from STCU

In this episode of The Segment, host Raghu Nandakumara sits down with Greg Mitchell, Application Administration Manager at STCU, for a candid, insightful look at what it really takes to drive security and innovation inside a modern, mission-driven financial institution.

Greg shares how his team is building resilience from the inside out—applying zero trust principles not as a buzzword, but as a practical, culture-driven framework for protecting core systems. 

From his roots in school district IT to leading major modernization efforts at STCU, Greg walks us through what it means to lead with intention, assume breach, and drive results with lean teams and strong partnerships.

You’ll learn:

• Why disaster recovery isn’t a one-time exercise, but a team muscle worth training
  
   
• How segmentation led to better cross-team relationships—not just better security
  
   
• The power of small wins (and small apps) to kickstart transformation
  
   
• Why enforcement beats perfection when it comes to securing infrastructure
  
   
• What zero trust really looks like in day-to-day operations—and how to start using tools you already have
  
   
• How STCU is approaching cloud expansion with Illumio
