A reference architecture implementing Zero Trust principles across a hybrid environment spanning on-premises data centers and multiple cloud providers, built on identity-aware proxies and workload identity.
Identity as the perimeter
Every access request — human or workload — is authenticated and authorized independently of network location, using a centralized identity provider federated across on-prem Active Directory and cloud-native IAM.
Segmentation strategy
Micro-segmentation is enforced at the workload level using service mesh mTLS policies in Kubernetes and security-group-per-workload patterns in traditional VM environments, rather than relying on VLAN or subnet-level segmentation alone.
Continuous verification
Session risk is re-evaluated continuously (not just at login) using signals like device posture, impossible-travel detection, and behavioral anomalies, with step-up authentication triggered automatically for elevated-risk sessions.
