Our organization doesn't use it because we're very small. However, we have deployed the service for more than 10,000 users. Our smallest customer had 25 users, and the biggest customer had over 10,000 users.

We have eight people in the maintenance team for Citrix NetScaler, plus 24/7 customer support for day-to-day issues. They are managing multiple customers. Their expertise is at the level of RL1, three at RL2, one at L3, and one at L4.

For some of my deployments, NetScaler has been strictly a replacement to get something new in. It was cheaper than F5. We took a chance on it. The return on investment is the fact that we spent less money on it. It does do its job and it holds well against F5.

Citrix ADC has increased the productivity of the staff by keeping all the applications available all the time.

It also increased the security of the online application by enabling the web application firewall feature.

With the amazing scalability features of the Citric ADC, we have been able to save money.

The product has helped us a lot with load balancing because we had limited experience with it.

We are replacing the necessity of any kind of load balance software/components (like Microsoft NLB, SAP Web Dispatcher, DNS Round Robin) and begin to centralize all Load Balancing necessities in the same NetScaler Hardware.

Citrix NetScaler supports our virtual appliance solutions.

The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications.

This has allowed us to secure Citrix remote access from the internet, as it is currently the only solution available that enables this.

• Allows the user to easily scale out application delivery.
• Provides secure remote access.
• Ease of management and business continuity support.
• Powerful, reliable, and feature rich solution all in one appliance.

We have a custom application that we use, and we were able to port it over from a legacy system into the ADC.

It has helped us to increase the resiliency and performance of the application.

This was a standard load-balancing solution provided to our customers. They didn't have many complaints about the way their traffic was being managed. We were able to handle specific requirements for persistence/stickiness.

Allowed secure access to authenticated user not on the network without having to download client side software

For desktop application management, I recommend the NetScaler edition. This product is like a Swiss army knife. Citrix NetScaler ADC supports the education front-end. 

In the organization, we have three systems based in Citrix technology, so there was logic to add a solution which give us security and a focal point of access. With Netscaler, we have a solution divided in two data centers, a secure and unique point of access, and balanced traffic between all the critical components in the Citrix solutions. For the last, we have a mature, solid, and secure component to complete the Citrix environment.

We have a lot of custom web applications that sometimes require custom header insertions.  Some of these apps are externally accessible. In our current network design, we were using a routable address for every external resource that we presented. Via the Content Switching, we are using one routable IP for various systems, preserving our number of allocated public addresses.

Imagine providing a brand new Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), cache for CSS or JS files and requires security features to be enabled. And do not forget that this service runs on a custom port, but you must publish it using the standard HTTP port, and you only have a public IP address and it's already in use on the NetScaler. You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)

We use it for Citrix NetScaler MPX deployments. It is being used for publishing Citrix XenApp, mostly for load balancing, but we have been evaluating solutions for deploying it in multi-data centers. 

It is used specially to provide Citrix Access Gateway to customers and their employees.

Deployment of NetScalers on our DMZ enables our organization to implement a secured gateway for our Web Portal, Inbound/Outbound application web service calls across our partners/clients, security, and Traffic Management.

We are able to offer more support to our customers.

It helps with load balancing. 

The NetScaler appliance has provided a lot of customers with greater high availability for their enterprise applications within a single site and across multiple locations. The largest, and potentially main reason to use Netscaler over the competition, is in Citrix environments. There is complete integration through the stack, and it has features which make it simple to securely provide access to enterprise data and applications.

Implemented dual-factor authentication on Outlook Web Access, making it well-protected.

We have removed all NLB clusters on web applications, increased HA for some applications and now we have possibilities such as rewrite and response with more flexible tools.

It helped many internal websites to expose online use with single star certificates.

It has improved my customers' base functionality by providing resiliency to their applications that reside on servers, as well as connectivity to remote applications.

Our company provides Managed Services and does Service Integration for our customers. We have deployed Citrix NetScaler for many customers. It has helped them to increase application up-time, scalability, and enhanced application performance and security.

provided a secure connection to critical information

They need to improve the ADC report

I have given this solution to many customers of NetScaler. It helped many businesses to gain high availability for their particular web application tiers.
