NetScaler Gateway can provide full VPN access, but it is not limited to that role. It also supports Citrix application and desktop access. The right comparison is between the access model your users need—network-wide tunneling or access scoped to particular applications—and the operational work each model requires. An application-focused ZTNA service may narrow access to named resources, but it still depends on identity policies, connectivity components, and support for your protocols. The official product documentation reviewed does not establish a universal security, speed, or cost winner.
What is the difference between a VPN and ZTNA?
A traditional remote-access VPN establishes a tunnel between a user’s device and an organization’s network. Depending on the configuration, that tunnel can give the device access to selected internal networks or carry all of its traffic through the organization. The authorized resources and routes determine what the user can reach.

Zero Trust Network Access (ZTNA) is an access model that applies identity-based policies to particular applications or services rather than treating network entry as the main unit of access. The implementation varies: a browser may connect to a private web application without a VPN client, while other private-network or non-web uses may need a client, a tunnel, or additional connectivity configuration. “ZTNA” does not mean that every protocol works without a client or that network planning disappears.
These are different ways to broker access, not a simple secure/insecure split. A VPN can be tightly restricted, and a ZTNA deployment can be misconfigured. Compare the resources each user needs, how identity and endpoint controls are enforced, and where traffic travels.

What does NetScaler Gateway provide?
Citrix NetScaler Gateway is a remote-access gateway that can deliver Citrix Virtual Apps and Desktops and can also support VPN access to configured internal resources. Citrix documentation describes virtual servers as user access points for configured services, with authentication, authorization, session policies, endpoint checks, and resource permissions available according to the deployment.
That makes Gateway a natural candidate when users’ main workflow is through Citrix-delivered applications or desktops, or when they also need network access through a full VPN. It does not establish that Gateway is inherently more secure or less expensive than an alternative. Start by listing the actual resources and access patterns rather than choosing based on a product label.

How does deployment location change the security boundary?
Gateway in a DMZ
Citrix documents the DMZ as a typical placement. In this design, an external user connects through the first firewall—normally using SSL on port 443—and Gateway terminates that user-side SSL connection. Gateway then connects on the user’s behalf to authorized internal resources through a second firewall. Internal firewall openings depend on the resources being made available.
This arrangement makes the boundary and permitted paths explicit, but a DMZ placement alone does not make a deployment secure. The firewall rules, authorization policies, identity controls, updates, certificate management, monitoring, and resilience still need to be designed and maintained.

Gateway behind one firewall inside the secure network
Citrix also documents placement behind a single firewall, with one interface connected to the Internet and the other to secure-network servers. Citrix warns that this arrangement is less secure for remote users because their traffic enters the secure network before they authenticate. That is a boundary trade-off administrators should weigh against their network design, not a claim that every such installation has the same risk.
Controls to settle before rollout
- Define which resources each user group may reach and which actions they may take; avoid granting broad network reach when a smaller permission set meets the need.
- Choose and test the supported authentication methods and identity flow. Citrix documentation lists methods including LDAP, RADIUS, TACACS+, client certificates, RSA with RADIUS, and SAML.
- Use a certificate from a known certificate authority for production. Citrix says its default self-signed SSL server certificate is suitable for testing or sample deployments, but is not recommended for production.
- Plan endpoint checks, session and authorization policies, logging and monitoring, patching, and failover as operational requirements rather than assuming the gateway placement handles them automatically.
What changes with full-tunnel and split-tunnel VPN?
With a full-tunnel configuration, the client captures all traffic from the device and routes it through Gateway. With split tunneling enabled, only traffic selected by policy and configuration uses the tunnel; other traffic follows a different path, commonly the device’s ordinary internet connection. The exact route behavior depends on the configured networks and policy.

Citrix’s full VPN setup uses Citrix Secure Access, Secure Hub, or Workspace app to establish an encrypted tunnel over port 443 or another configured Gateway port. Administrators define the networks and resources to secure, along with settings such as split tunneling, user IP address pools, proxy use, domains, timeouts, and single sign-on.

- Consider split tunnel when only defined internal destinations need the tunnel and the organization accepts that other traffic takes a separate route. Account for how that affects inspection, DNS, and user experience.
Neither setting is universally preferable. The choice depends on the organization’s inspection requirements, bandwidth, resilience, and user workflows; the product documentation does not establish a best setting for every environment.

How do ZTNA alternatives compare in deployment?
Cloudflare Access as an application-scoped example
Cloudflare documents policies in front of applications. For private web applications, users can connect in a browser without VPN software, while a secure tunnel connects the application. Non-HTTP resources have different requirements: Cloudflare documents client-based and clientless approaches, but private-network access still requires connectivity and resource-specific controls. Depending on the use case, a client can provide a network-like experience.
In practice, administrators still need to plan identity integration, policy, connectors or other network connectivity, DNS, routes, and protocol support. The fact that a service is described as a VPN replacement does not demonstrate that it covers every subnet, legacy protocol, or endpoint workflow in an existing VPN deployment.
Cisco Secure Client and phased adoption
Cisco Secure Client 5.1 administrator guidance treats VPN traffic selection and its Zero Trust Access module as distinct configured capabilities, with module-specific requirements and compatible versions. This is a reminder that VPN and ZTNA functions may coexist during a phased transition; a ZTNA module should not be assumed to replace every use of a network VPN.
Which access model fits which requirement?
| Decision area | NetScaler Gateway / full VPN | Application-scoped ZTNA example | What to verify |
|---|---|---|---|
| Resource scope | Can provide VPN access to configured internal networks and Citrix-delivered resources. | Policies may target applications, private IP addresses or hostnames, or infrastructure, depending on the product and configuration. | Which users need subnet-level access, and which need only specific applications or admin services? |
| Network placement | Citrix documents a common DMZ placement and a behind-one-firewall option with an authentication-boundary trade-off. | Cloudflare documents connecting private applications or networks through its tunnel and related connectivity mechanisms. | What inbound exposure, connector placement, firewall rules, and failure domains are involved? |
| Traffic routing | Full tunnel can carry all device traffic; split tunnel changes which traffic traverses Gateway. | Policies may broker per-application access; some non-HTTP or private-network cases require a client or network connection. | Which traffic must be inspected, and where will DNS, internet egress, and private routes be handled? |
| Identity and device controls | Supports authentication, authorization, session policies, and endpoint checks. | Policies can gate application access by identity and configured context. | Check identity provider, MFA, posture signals, certificates, lifecycle controls, and applicable entitlements. |
| Citrix and other workload support | Integrates with Citrix applications, desktops, and Workspace flows. | Compatibility depends on the alternative and configuration. | Pilot ICA/HDX, legacy protocols, printers, file shares, admin tools, and actual endpoint types. |
| Operations | The organization operates the Gateway deployment, network path, policies, certificates, and supported updates. | Cloud-delivered approaches add provider and connector dependencies; responsibilities vary by service and design. | Assign patching, monitoring, connector support, client support, and failover ownership. |
| Cost and entitlements | Not established in the official documentation reviewed; confirm current terms with Citrix or a reseller. | Not established in the official documentation reviewed; confirm current terms with the provider. | Request current, region-specific quotes and confirm exactly which features and support are included. |
This is a planning framework, not a scored product ranking. The reviewed official documentation does not provide independent, apples-to-apples security or performance results for these options.
Quick Recap
How should an organization decide whether to replace its VPN?
- Inventory access needs. Separate Citrix application and desktop workflows, named private applications, shared files, admin tools, and users who need network-level access.
- Map routes and boundaries. For a VPN, document full- or split-tunnel behavior, address pools, DNS, and firewall paths. For ZTNA, document application connectors, private routes, identity flow, and dependencies.
- Check protocol and endpoint compatibility. Pilot each required application and device type. Validate the actual workflow rather than inferring compatibility from a general VPN-replacement description.
- Design policies and recovery. Define least-privilege access, authentication and endpoint conditions, logging, connector or gateway failure handling, and support ownership.
- Run a phased pilot. Keep the existing access path available for users or workloads that have not passed validation. Measure operational outcomes in your environment; vendor documentation is not an independent performance benchmark.
- Confirm lifecycle and commercial details. Check supported versions, current security advisories, licensing, and support entitlements with the relevant vendor before committing to a migration.
