We use the NetScaler ADC in three primary use cases. The first is to provide load balancing services for our internal applications. The second is for Global Server Load Balancing (GSLB) to provide data center resiliency and failover of our externally accessible services, as well as proximity-based access. The third is for the Unified Gateway to securely provide external access to some of our key applications. We deploy VPX appliances running in our VMware environment.

GSLB allows me to do active/active or active/passive deployment of services
Pros and Cons
- "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."
- "Unified Gateway allows me to provide secure external access to applications for suppliers and customers while requiring Multi-Factor Authentication."
- "The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support."
What is our primary use case?
How has it helped my organization?
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.
What is most valuable?
The features I find most useful are
- Load Balancing
- GSLB
- Unified Gateway.
I love being able to terminate connections to the boxes and look at all of the packet headers to determine which way I want to send the traffic next. GSLB provides amazing ability to do active/active or active/passive deployment of services. Unified Gateway allows me to provide secure external access to applications for suppliers and customers while requiring Multi-Factor Authentication.
What needs improvement?
The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community.

Offers a superior user experience by delving into the HDX protocol
Pros and Cons
- "Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."
- "There is room for improvement regarding the pricing policy for Citrix offices."
What is our primary use case?
I use Citrix NetScaler as a gateway to provide secure access to virtualized desktops and applications.
What is most valuable?
Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data. The seamless integration with Citrix tools enhances both performance and security, creating a powerful combination for optimal IT environments.
What needs improvement?
There is room for improvement regarding the pricing policy for Citrix offices. In the past, the gateway was cost-effective, but there has been a shift, and the current pricing seems too high.
For how long have I used the solution?
I have been working with Citrix NetScaler for many years.
What do I think about the stability of the solution?
I would rate the stability of the solution as a seven out of ten.
What do I think about the scalability of the solution?
I would rate the scalability of the solution as an eight out of ten.
How are customer service and support?
Tech support for NetScaler can be frustrating. When opening a case, I often spend much time with first-level support, who sometimes lack programming knowledge. The process involves repeating details when the case is escalated to an engineer which causes delays. Overall, I would rate the support as a three out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
Before using Citrix NetScaler, I had experience with similar products. I recall working with Citrix Gateway for server access, but it involved a server running an application on a Windows server. I have also dabbled a bit with other vendors like F5 for feature integration. However, integrating with Citrix has been challenging as they are not very open to external integrations.
What's my experience with pricing, setup cost, and licensing?
The solution is quite expensive. Regular security audits reveal frequent vulnerabilities, requiring monthly patches.
What other advice do I have?
Overall, I would rate Citrix NetScaler as a seven out of ten.

A flexible product with a good VPN and easy-to-use load balancing capabilities
Pros and Cons
- "I find all of it to be valuable, because of the flexibility that is built into this product."
- "There are certain features that are very useful and Citrix makes you pay a bit more for them."
What is our primary use case?
We are using Citrix ADC as a VPN appliance, and use it as a load balancer for a few different services.
How has it helped my organization?
We have a custom application that we use, and we were able to port it over from a legacy system into the ADC.
What is most valuable?
I find all of it to be valuable, because of the flexibility that is built into this product.
If we need an on-premises load balancer, it's easy enough to spin those up here an there and the VPN seems to be pretty solid as well.
What needs improvement?
The licensing model that Citrix employs need to be improved. There are specific features that we like but are not available at our licensing level.
There are certain features that are very useful and Citrix makes you pay a bit more for them. I think that they should be included as default features.
In the next release, I would like to have the ability to inspect the SSL payload. It should be included by default.
For how long have I used the solution?
I have been using Citrix ADC for almost a year.
What do I think about the stability of the solution?
It's a stable product and I haven't found any issues with it. It's been working well for us this entire time.
What do I think about the scalability of the solution?
Scalability is not really applicable in our case. We have moved towards the cloud.
I don't believe that we plan to scale on-premises any further.
We have approximately 500 users in the company who are using this solution.
How are customer service and technical support?
Technical support is good. We have reached out a couple of times and they were able to assist us quickly, even on the weekend.
I would rate technical support a nine out of ten.
It depends on who you get, there are some who want to redirect you to professional services. Once you get them on board, their service is good.
Which solution did I use previously and why did I switch?
Previously, we used Juniper VPN. The hardware was older.
How was the initial setup?
The initial setup was fairly complex. There is a bit of a learning curve.
What about the implementation team?
We worked with professional services during our deployment.
What's my experience with pricing, setup cost, and licensing?
It's an expensive product but it works well.
What other advice do I have?
My advice to anyone who is looking at implementing Citrix ADC is if they need flexibility, it's a stable product. It's one of the better appliances that I have used, even in a virtual environment, it's working great. I can recommend it.
I would rate Citrix ADC a nine out of ten.

Senior Systems Engineer at a computer software company with 5,001-10,000 employees
Provides IP Reputation and bot protection features and can be used for load balancing purposes
Pros and Cons
- "We use the solution's IP Reputation and bot protection features."
- "The licensing model and technical support of the solution could be improved."
What is most valuable?
Not many of our customers use the solution's web application firewall. We use the solution's IP Reputation and bot protection features. We use the solution mostly as Citrix and Gateway ICA proxy and load balancing. There are a lot of changes with the solution, but Citrix NetScaler has quite a comprehensive portfolio of training courses.
What needs improvement?
The licensing model and technical support of the solution could be improved. The exchange rate with the local currency contributes a lot to why some of our customers are looking at alternatives.
For how long have I used the solution?
I have been working with Citrix NetScaler since it first came onto the market. I have been using the solution before the Gateway feature was a part of NetScaler, and it was a stand-alone product. I have been using the solution since Citrix acquired the product.
What do I think about the scalability of the solution?
Citrix NetScaler is a scalable solution.
What other advice do I have?
Citrix NetScaler has many features. The solution's basic features, like load balancing and Gateway, are pretty easy to use. It becomes complicated very, very quickly in large environments because it has many features. I would recommend the solution to other users.
There are much cheaper alternatives if you just need the solution for basic load balancing. There are no alternatives to Citrix NetScaler if you want to use it as a Gateway and access it from the public network. Integrating Citrix NetScaler with the existing infrastructure and applications is pretty straightforward once you get the hang of things.
Overall, I rate the solution a nine out of ten.

User-friendly and great functions
Pros and Cons
- "Most of the functions are user-friendly and great."
- "There are some drawbacks, such as using EUG for specific configurations. It could be improved."
What is our primary use case?
We're using NetScaler for compression and optimization features.
What is most valuable?
Most of the functions are user-friendly and great. We also have mobile features that are simple but effective.
What needs improvement?
There are some drawbacks, such as using EUG for certain configurations. It could definitely be improved. Moreover, compression features could be better since it uses too much CPU and is not very effective.
In terms of additional functionality, the capture feature could be improved to make it easier to use, and schedules could also be better for me.
For how long have I used the solution?
I have been using this solution for eight years.
What do I think about the stability of the solution?
There are nine users in our organization using this solution. It is a stable solution within this capacity. Sometimes we faced bugs, but in general, it hasn't affected the general usage.
What do I think about the scalability of the solution?
If you use the latest version, it is quite a scalable solution. I would rate the scalability of NetScaler an eight out of ten.
How are customer service and support?
We've had poor experiences with customer support partners in the past two years. If some company changes, it's a bad thing. The customer support is not good for us. It is not helpful as well as have very slow response time.
How was the initial setup?
The initial setup is actually very simple.
What other advice do I have?
Overall, I would rate the solution an eight out of ten. I would definitely recommend using the solution.
Which deployment model are you using for this solution?
On-premises

Independent Consultant at a construction company with 201-500 employees
A single tool capable of handling thousands of users while staying stable at the same time
Pros and Cons
- "Just one solution can handle thousands of users... So, it is a very convenient tool to use."
- "Some features of Citrix ADM are available on the cloud, which could really be helpful if they were available on an on-premise version."
What is our primary use case?
With Citrix ADM, one can manage NetScaler and ADC. One can also gather data on remote users, especially information on their bandwidth and the resources they use.
What is most valuable?
Feature, wise, one of the things that I use is the SSL dashboard to make sure my certificates are up-to-date on my NetScalers. So, it's very handy.
What needs improvement?
Some features of Citrix ADM are available on the cloud, which could really be helpful if they were available on an on-premise version. At the moment, I can't explain it in detail since I don't utilize the Microapps or StyleBooks in the solution, even though both are available in the cloud version. However, they are not available in the on-premise version. So, I use the on-premise version.
For how long have I used the solution?
I have experience with Citrix ADM for twenty years. I am a reseller and a partner of Citrix.
What do I think about the stability of the solution?
It's a virtual appliance, and once it's up and running, it just runs. So, it is a stable product.
What do I think about the scalability of the solution?
Just one solution can handle thousands of users and hundreds of ADCs. So, it is a very convenient tool to use.
How are customer service and support?
Currently, the support team is experiencing a shortage of staff, making it difficult for users to reach someone knowledgeable.
How was the initial setup?
The solution's initial setup was very easy. If ten means super easy, I rate it only an eight on a rating bar.
What other advice do I have?
I would recommend those planning to use the solution, especially if they use or have ADCs or NetScalers in their environment. There are a lot of people who don't use the solution when they should.
There's still a lot of scope for growth and many features that can be added to the solution. Also, I'm unfamiliar with some of the features, so I can't speak on all of them now. Overall, I rate the solution an eight out of ten.
