I'm a network security architect at a mid-sized company, and we're finally getting executive buy-in to begin migrating our legacy perimeter-based security model towards a zero trust architecture, but the sheer scope of the project is daunting. We have a mix of on-premises systems and cloud services, and I'm struggling to prioritize the initial phases, whether it's implementing strict identity verification, segmenting our network, or securing all our application access points first. For other teams who have undertaken this journey, what was your practical roadmap for implementing zero trust architecture in a hybrid environment? Did you start with a specific pillar like identity or device security, and what were the biggest technical and cultural hurdles you faced in moving away from the traditional "trust but verify" mindset inside the network?
