Secure remote access to hybrid cloud and SaaS. A comprehensive, secure remote access solution. Citrix NetScaler Unified Gateway consolidates remote access infrastructure to provide single sign-on across all applications whether in a datacenter, in a cloud, or delivered as SaaS. It allows people to access any app, from any device, through a single URL. Citrix NetScaler Unified Gateway offers Single sign-on (SSO) to VDI, web and SaaS applications. Remote access to all applications across any data center or cloud. ICA proxy and secure delivery of VDI applications. One solution for secure access to all your apps. People today need to access their apps from anywhere and on any device. NetScaler Unified Gateway provides best-in-class security and a seamless user experience by providing secure access and SSO across enterprise, VDI, web, or SaaS app hosted on any data center or cloud through a single URL.

NetScaler Unified Gateway consolidates multiple remote access solutions, provide Single Sign-On, multi-factor authentication, end-to-end monitoring across all application traffic and contextual access control across on-premise VDI, web, cloud and SaaS apps. It helps reduce costs, simplify management, and improve the user experience. Consolidate your secure remote access delivery infrastructure with One URL. Putting the “secure” in secure remote access. Solve the application visibility challenge with NetScaler Insight Center. Transition to hybrid cloud and SaaS with NetScaler Unified Gateway. Implementing a traditional SSL VPN solution or an IDaaS (IDaaS) solution will not provide Single Sign-On to all applications and data. While an SSL VPN will provide network access and SSO to applications in a datacenter, an IDaaS solution will just provide SSO to applications in the cloud or delivered as SaaS.

Citrix NetScaler Unified Gateway — Hybrid Cloud And SaaS

Due to lack in functionality of SSL VPN solutions to provide SSO, traffic monitoring, and access security to SaaS applications, customers deployed IDaaS as a separate solution from an existing SSL VPN-based solution. In addition to SaaS applications, many enterprise customers have deployed an MDM solution, and a VDI solution from one or multiple vendors. These solutions each require an additional gateway since most vendors do not provide a single access point supporting both VDI and MDM solutions. As a result, many enterprise customers have up to 5 gateways deployed in their datacenter — all from different vendors. This redundancy, over the years, has caused data centers to be complex and has inhibited customers from moving to cloud or highly agile datacenter networks. Citrix Unified Gateway provides users with one access point and SSO to business applications and data deployed in a datacenter, the cloud, or delivered as SaaS across a range of devices — laptops, desktops, thin clients, tablets, and smart phones.

Single Sign-On To All Applications

NetScaler Unified Gateway provides federated identity and supports SAML 2.0, OAuth, and OpenID to achieve Single Sign-On across all applications whether they are web, VDI, enterprise, or SaaS applications. NetScaler Unified Gateway provides SSO to SaaS applications such as Office 365 and Salesforce, and keeps the user directory on-premises. It can be implemented as an IdP or proxy for ADFS and provides SSO to SaaS. NetScaler Unified Gateway provides nFactor authentication mechanisms and allows granular control over who is accessing the network; what is being accessed; and how and when it is accessed. It supports all the authentication mechanisms such as RADIUS, TACACS, NTLM, Diameter, SAML 2.0, OAuth 2.0, and OpenID 2.0. NetScaler Unified Gateway allows granular access control to business applications based on the state of the end-user device, user, user location, and other data. An IT administrator can create, manage, and enforce these policies to access data securely in an application environment.

Consolidate SSL VPN Infrastructure

Citrix NetScaler Unified Gateway provides one URL and consolidates remote access infrastructure. It provides remote access from any device to any application. For IT, this helps improve efficiency and reduce cost of ownership. For end users, it provides one URL for accessing any application from any location and improves the user experience. Users can now access any application, using any device type, from any location. Given the spread of enterprise data centers or customers across multiple geographies, you may want to present different content to different users. For example, you may want to allow users from an IP range of a customer or partner to have access to a special web portal or to content relevant to users from a specific geographical area and in a specific language. You may also want to present content tailored to specific devices, such as smartphones. Content switching enables the Citrix NetScaler Unified Gateway appliance to distribute client requests across multiple servers based on specific content that you wish to present to users.

Secure Access To VDI Applications

Citrix NetScaler Unified Gateway provides HDX proxy to Citrix XenApp and Citrix XenDesktop applications. It provides proxy in two modes: Basic and Advanced. Basic HDX proxy  — Basic HDX proxy includes passing the HDX protocol through the gateway appliance. It also provides basic load balancing and two-factor authentication for end users. Advanced HDX proxy — Advanced HDX proxy includes contextual access control with SmartAccess and SmartControl policies; GSLB across any datacenter and the cloud; multi-factor authentication; and high availability for Citrix XenApp and Citrix XenDesktop workloads. NetScaler MAS provides HDX Insight, that allows IT organizations to achieve end to end visibility of Citrix XenApp and Citrix XenDesktop applications. No other vendor, apart from Citrix, provides this visibility and therefore it is a valuable tool for IT administrators and support teams to proactively resolve issues and have better support SLAs.

Advanced Layer-4

Current SDN technologies operate at Layer-2 and Layer-3 and are missing the opportunity to truly deliver on the full promise of the solution. The next-generation NetScaler platform unifies best-in-class Layer-4 and Layer-7 network services into an application control layer, and can integrate this application control with both existing transport networks and emerging SDN technologies. This application control layer can make emerging Layer-2 and Layer-3 SDN architectures completely app-driven, by using app-centric definitions and policies to simplify network design, while making the whole network more intelligent.

With its centralized management plane, NetScaler alleviates the overhead and sprawl usually associated with serving complex networking applications. Through intuitive workflows, administrators can enable provisioning and deploying of new network services on demand. The central plane also acts as a single point of visibility, providing a coherent view of the operational characteristics for all the instances running on the appliance. This software-driven approach makes it possible to successfully support the dynamic changes inherent in today’s cloud-based, app-driven environment.

Benefits

Compared to the advancements in compute and storage virtualization, networking has fallen behind in fully realizing the promise of enterprise cloud computing. The dynamic nature of cloud services requires a new level of flexibility and scalability, which goes beyond the capabilities of today’s data center networks. Transitioning to software-defined networking (SDN) incorporates programmability and agility into your network, enabling it to keep pace with business demands.
