implementing-zero-trust-network-access

separate

Configures Zero Trust Network Access (ZTNA) in AWS, Azure, and GCP using identity-aware proxies, micro-segmentation, and continuous verification with conditional access policies, replacing VPN-based access with BeyondCorp-style architectures. Use when replacing VPN remote access with identity-based controls, limiting lateral movement via micro-segmentation, or exposing cloud workloads to authenticated users without public internet exposure.

When to use

• When replacing traditional VPN-based remote access with identity-based access controls
• When implementing micro-segmentation to limit lateral movement within cloud networks
• When compliance or security strategy requires zero trust architecture adoption
• When providing secure access to cloud workloads without exposing them to the public internet
• When building context-aware access policies based on user identity, device health, and location

When not to use

• Complete replacement for network security controls
• Protecting internet-facing public applications
• IoT device access where identity-based authentication is not feasible
