Security You Should Know · 2026-07-27 · 18 min
In this episode, Andrea Sivieri , Chief Product and Technology Officer at CoreView, explains how CoreView secures that overlooked layer, the configuration, permissions, and structure of a Microsoft 365 tenant rather than just the data flowing through it. Joining him are Davi Ottenheimer , principal at Flying Penguin, and Will Gregorian , CISO at Galileo Medical . Want to know: Why does Microsoft's own admin console give you roughly a thousand ways to configure a single setting? What's the actual difference between securing your Microsoft 365 data and securing your Microsoft 365 configuration? How does a "virtual tenant" stop one compromised admin account from exposing your entire company? How do you stay ahead of a vendor that can change its APIs or shut off access without warning? How do you catch a change to your tenant that you had no way of seeing in the first place? How far back can you rewind a tenant's configuration history, and why does that number matter? What does managing a 2.7 million-user tenant reveal about resilience that a small business never has to think about? Check out the episode for the answers you need. A huge thanks to our sponsor, CoreView
