SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Traditional VPNs grant broad network access and expose a large attack surface. This Skill guides the deployment of Zscaler Private Access (ZPA) so users reach only specific private applications through identity- and posture-verified, outbound-only brokered connections.

Core Features & Use Cases

  • End-to-End ZPA Deployment: Covers IdP integration (SAML/OIDC, SCIM), App Connector provisioning, server groups, and Client Connector rollout via MDM.
  • Microsegmentation & Policy Design: Defines application segments by FQDN, port, and protocol, with access policies combining identity, device posture, and context.
  • Misconfiguration Verification: Includes checks for direct app reachability, over-broad segments, default-allow policies, and exposed connector ports.
  • Use Case: A security team decommissioning a legacy VPN uses this Skill to stand up ZPA connectors in AWS and on-premises, segment HR and finance applications, enforce device posture via Intune, and stream logs to Splunk before cutting over users.

Quick Start

Use this skill to plan and validate a Zscaler Private Access deployment that replaces our VPN with identity-based access to internal applications.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I replace a VPN with Zscaler Private Access?▼

Deploy App Connectors in each application environment, integrate your identity provider via SAML or OIDC, define application segments by FQDN and port, then enforce access policies with device posture checks. Roll out the Client Connector via MDM and decommission the VPN after validation.

How does Zscaler ZPA microsegmentation work?▼

ZPA segments applications by specific IPs, FQDNs, ports, and protocols rather than granting network-level access. Users connect only to authorized application segments through the ZPA Service Edge, never to the underlying network.

Does ZPA work with Okta or Azure AD?▼

Yes, ZPA integrates with Okta, Azure AD, and Ping Identity using SAML 2.0 or OIDC for authentication. SCIM provisioning synchronizes users and groups automatically for policy assignment.

How do I verify ZPA is actually blocking direct access?▼

From a host without the Client Connector, attempt to reach the protected app by IP and FQDN; it must time out. Also disable the Client Connector to confirm access drops, and test that non-compliant devices are blocked by posture profiles in ZPA logs.

What are common ZPA misconfigurations to avoid?▼

Common issues include applications still reachable directly, segments defined as broad CIDRs like 10.0.0.0/8, default-allow policy ordering, Browser Access open to unmanaged devices, and App Connectors with exposed inbound ports.
