Security is our top priority as we move our sensitive data to the cloud. We are currently using a hybrid setup with Azure and an on-premise data center. I want to know how to effectively apply Zero Trust principles within this <Cloud (AWS/Azure/GCP) Computing> framework. What are the essential identity and access management tools that can bridge the gap between our local servers and Azure AD?

Implementing Zero Trust in a hybrid environment starts with Identity as the new perimeter. You should be leveraging Azure AD (now Microsoft Entra ID) Connect to sync your on-premise identities. The most critical step is enforcing Conditional Access policies, which evaluate every login attempt based on user location, device health, and risk level. You should also look into Azure Bastion for secure RDP/SSH access without exposing public IPs. By assuming that every request—regardless of where it originates—is a potential threat, you can create a much more resilient security posture for your enterprise.
Sandra, how do you handle legacy applications that don't support modern authentication protocols like OIDC or SAML?
You should also look at implementing 'Just-In-Time' (JIT) access to minimize the window of opportunity for attackers on your virtual machines.
JIT access is a brilliant addition to Zero Trust. Reducing persistent administrative privileges is one of the most effective ways to stop lateral movement during a breach.
For those legacy apps, Jason, the Azure AD Application Proxy is your best friend. It allows you to publish on-premise web apps to the cloud securely. It acts as a gateway that requires a pre-authenticated Azure AD session before the user ever touches your internal network, essentially wrapping old apps in modern security.
