Prisma Access protects mobile users through two main connection models: GlobalProtect and Explicit Proxy. Current Palo Alto Networks documentation describes GlobalProtect tunnel mode as the default full-tunnel agent mode for securing all applications, ports, and protocols, while Explicit Proxy focuses on Secure Web Gateway-style proxy traffic. The mobile-user architecture also ties together portal\/gateway configuration, authentication, DNS, address pools, private-app connectivity, Host Information Profile (HIP) data, and Strata Logging Service.<\/p>\n

Within Palo Alto Security Operations<\/a>, mobile-user design is not just a VPN rollout. It determines which traffic receives security policy, how users authenticate, where private apps connect, which device-posture signals are available, and how incidents are investigated after endpoints leave the corporate network.<\/p>\n

Prisma Access Explicit Proxy<\/a> covers the proxy branch of the design. This page focuses on the broader mobile-user operating model and the GlobalProtect path.<\/p>\n

Choose the connection method from traffic scope<\/h3>\n

GlobalProtect tunnel mode secures internet, SaaS, private cloud, and internal resources across all application ports\/protocols.<\/p>\n

Explicit Proxy is appropriate for web\/SaaS traffic and organizations migrating from traditional proxy architectures.<\/p>\n

Hybrid deployments can combine the two, but the organization should be able to explain which traffic is inspected by which path rather than relying on accidental client behavior.<\/p>\n

Portal and gateway design controls the user experience<\/h3>\n

The GlobalProtect portal provides configuration to the endpoint, while gateways terminate user tunnels and apply security policy.<\/p>\n

Prisma Access creates cloud gateways across supported locations and dynamically scales according to deployment and licensing.<\/p>\n

Plan portal hostname, certificates, gateway regions, authentication, DNS, IP pools, and routing before endpoint deployment so the client does not become the place where architecture mistakes are discovered.<\/p>\n

Always-on modes reduce user bypass<\/h3>\n

Current GlobalProtect app settings include user-logon Always On, pre-logon Always On, on-demand, and pre-logon-then-on-demand patterns.<\/p>\n

Always-on designs improve policy consistency because the user cannot simply forget to connect.<\/p>\n

Pre-logon requires machine-certificate planning and should be tested with device enrollment, password changes, captive networks, and help-desk recovery.<\/p>\n

HIP data enables device-state policy<\/h3>\n

GlobalProtect can report host information used to create policy based on endpoint state such as patching, disk encryption, antivirus\/EDR, certificates, and other posture data.<\/p>\n

Use HIP conditions for access decisions to sensitive apps rather than assuming identity alone makes every endpoint trustworthy.<\/p>\n

Keep HIP object logic maintainable; overly complex posture policy can lock out legitimate users after routine OS or security-product updates.<\/p>\n

Private app access needs a corporate access path<\/h3>\n

Current Prisma Access setup guidance requires a corporate access node\/service connection or equivalent supported private-access architecture when mobile users must reach connected networks.<\/p>\n

Private DNS, route advertisement, zones, security policy, and overlapping IP space all affect success.<\/p>\n

Prisma Access Service Connections<\/a> is the key companion article for the data-center\/cloud connectivity layer.<\/p>\n

IP pools and client addressing must scale<\/h3>\n

Mobile-user tunnel IP pools need enough address space for peak concurrent users, multiple regions, reconnects, and operational headroom.<\/p>\n

Address planning should avoid overlap with data-center, branch, cloud VPC\/VNet, and partner networks.<\/p>\n

A connection can authenticate successfully and still fail application access because the assigned client range collides with another route domain.<\/p>\n

Authentication should support resilient identity<\/h3>\n

Prisma Access can use enterprise authentication profiles and certificate\/SAML integrations depending on design.<\/p>\n

Test IdP outage, MFA failure, certificate expiry, password reset, new-device enrollment, and emergency access.<\/p>\n

Mobile-user security becomes an identity availability problem if every tunnel depends on one unreachable or misconfigured authentication path.<\/p>\n

Gateway location and performance should be monitored<\/h3>\n

Users expect Prisma Access to select or connect them to an appropriate gateway\/region with acceptable latency.<\/p>\n

Measure connection time, tunnel stability, throughput, packet loss, gateway changes, and application performance by geography.<\/p>\n

Autonomous DEM in Prisma Access<\/a> provides the experience-monitoring layer for understanding endpoint\/network\/application performance.<\/p>\n

Split tunneling changes the inspection boundary<\/h3>\n

Split tunneling can improve performance and reduce unnecessary backhaul, but every excluded route\/domain\/application becomes traffic that does not receive the same Prisma Access inspection path.<\/p>\n

Document business and security reasons for exclusions and review them after SaaS or application changes.<\/p>\n

Do not allow split-tunnel exceptions to accumulate until the \u201calways-on\u201d client secures only a small fraction of user activity.<\/p>\n

Logging must connect user identity, device, gateway, and policy<\/h3>\n

Collect GlobalProtect system\/authentication, traffic, threat, URL, decryption, and HIP-related evidence in the central logging plane.<\/p>\n

Use Strata Logging Service<\/a> to keep network security logs available for investigation and forwarding.<\/p>\n

Incident responders should be able to reconstruct where a user connected from, which device posture applied, which policy allowed the traffic, and which threat controls triggered.<\/p>\n

Prisma Access mobile users succeed when remote access behaves like part of the security architecture<\/h3>\n

The mature deployment chooses GlobalProtect versus Explicit Proxy deliberately, uses resilient authentication, sizes IP\/routing correctly, applies posture-aware policy, monitors user experience, governs split tunneling, and retains high-quality logs.<\/p>\n

Mobile access should give users consistent protection outside the office without hiding the network, identity, device, and application dependencies behind one \u201cVPN connected\u201d status.<\/p>\n

Gateway-location strategy should follow where users actually connect, not only where offices exist. Remote workers may live in regions with no branch footprint. Review connection telemetry and Autonomous DEM experience data to decide where additional Prisma Access locations improve latency or resilience, and retest after acquisitions or workforce-distribution changes.<\/p>\n

GlobalProtect client upgrades should be managed like endpoint-security software. New Prisma Access features can require minimum GlobalProtect versions, and current setup guidance includes version prerequisites for some IP optimization features. Use staged software rings, monitor connection failures, and keep rollback packages available rather than forcing the entire remote workforce onto one untested client build.<\/p>\n

IP Optimization should be decided before certain new deployments because current documentation states the setting can be one-way\/initial-deployment specific and has version\/IPv6 limitations. Architecture teams should review address efficiency, client compatibility, and future IPv6 needs before enabling an optimization that cannot be changed casually later.<\/p>\n

Pre-logon authentication depends on machine certificate issuance before the user session exists. That means MDM\/endpoint provisioning, PKI, certificate renewal, and device replacement all affect remote access. Test a newly imaged device, expired certificate, lost device, and off-network password reset to verify pre-logon does not strand users during exactly the recovery scenarios it is intended to help.<\/p>\n

Mobile-user DNS should be designed separately for public and private namespaces. Internal domains may need corporate DNS reached over service connections or private access nodes, while public queries may use Prisma Access resolvers according to design. Split-horizon and overlapping namespaces should be tested because DNS failures often appear to users as ‘VPN works but application is down.’<\/p>\n

Security policy should follow user and device context rather than only tunnel IP. User-ID, HIP, application, URL category, risk, and zone information can make access more specific than one broad Mobile-Users-to-Trust rule. Keep rules readable enough that responders can explain why a given user\/device reached a private resource at a specific time.<\/p>\n

Always-on clients need a captive-portal strategy for hotels, airports, and guest Wi-Fi. If the tunnel intercepts access before the user can complete local network authentication, the endpoint can look offline. Use supported captive-portal detection\/bypass behavior and test common public network patterns without creating permanent broad bypasses.<\/p>\n

Mobile users can become a route between unmanaged local networks and corporate resources if endpoint controls are weak. Host firewall, split tunnel, local network access settings, endpoint posture, and device-management policy should be reviewed together. Remote access security depends on the endpoint network stack as well as the cloud gateway.<\/p>\n

Operational dashboards should separate authentication failure, portal failure, gateway failure, tunnel negotiation, DNS, private routing, decryption, and security-policy block. One ‘GlobalProtect disconnected’ metric is not enough to distinguish identity outages from regional dataplane problems or endpoint-version regressions.<\/p>\n

User offboarding should revoke remote-access ability quickly. Disable identity, invalidate sessions\/certificates as required, remove device trust, and monitor late connection attempts. Contractors and temporary workers need expiry built into identity and Prisma Access policy rather than relying on a help-desk ticket after the engagement ends.<\/p>\n

Mobile-user capacity planning should consider concurrency peaks during office closures, travel events, incident-driven work-from-home, and application outages that cause repeated reconnects. Test beyond normal daily averages so address pools, gateways, authentication, and private-access paths remain stable under sudden remote-work surges.<\/p>\n

Client configuration should minimize user-editable settings for always-on security populations. Where the product supports it, centrally manage portal\/gateway selection, split tunneling, and certificate trust so users cannot accidentally or intentionally weaken inspection. Provide a separate troubleshooting process rather than exposing broad local override controls.<\/p>\n

Device quarantine should have a recovery workflow. If HIP or endpoint-security posture blocks private access, users need clear remediation instructions and a way to regain access after patching\/encryption\/EDR health is restored. Security policy is stronger when failed posture leads to predictable repair instead of help-desk pressure to disable the check.<\/p>\n

Remote-access metrics should be segmented by OS, client version, region, ISP, gateway, authentication method, and application path. This makes it possible to spot one bad client release or regional ISP issue without changing global policy for every mobile user.<\/p>\n

Keep mobile-user policy and client versions under continuous review.<\/p>\n

Mobile-user policy should be validated across normal and degraded paths: office, home, hotel, captive portal, poor connectivity, and private application access. Consistent enforcement matters, but so does a predictable recovery experience when the endpoint cannot reach a required service.<\/p>\n","protected":false},"excerpt":{"rendered":"
