Implementing Zero Trust architecture for remote workforce - where to start?

Our organization is transitioning to a Zero Trust security model to support our growing remote workforce. We currently have a traditional perimeter-based security approach with VPN access. Key requirements: - Support for 500+ remote employees - Access to on-premises and cloud resources - Compliance with industry regulations - Minimal disruption to user experience I understand the core principles of Zero Trust (never trust, always verify), but I'm looking for practical implementation guidance: 1. Which vendors/solutions should we evaluate? 2. What's a realistic timeline for implementation? 3. What are common pitfalls to avoid? 4. How do we handle legacy applications that don't support modern authentication?
