What is most valuable?

It depends on your needs. * If you need PCI-compliance and have high security requirements, WAF is the most valuable feature. * If you need to monitor your load-balancing services with complex types of monitoring, make sure everything is alright, and load balancing is important, Content Switching… more »

How has it helped my organization?

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… more »

What needs improvement?

We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers.

Which solution did I use previously and why did I switch?

We deployed NSX on our infrastructure last year. It was great, except for the standard load balancer. We were already using Netscaler MPX on our physical level and expected almost the same features from NSX load balancer. But it was really hard to even monitor the services on it, and we did not have… more »

What do you think of Citrix ADC?

What is our primary use case?

We are using it for two-factor authentication for our Citrix architecture, for secure access to our internal applications. It is mostly for admins who use it for remote access, as well as some users. We do not use it as a web application firewall. We are running a virtual edition, not an appliance.

What is most valuable?

The most valuable feature, absolutely, is its high-security. This product is based on Unix and there have been no problems since we started using it in 2015.

What needs improvement?

Occasionally, our admin has to use the command line. If they could only use the Web GUI it would be better.

For how long have I used the solution?

Three to five years.

What do I think about the stability of the solution?

There have been no issues…

What is most valuable?

* Global servers * Load balancing We need multi-site and DNS failover.

How has it helped my organization?

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.

What needs improvement?

It is difficult to customize. It is more difficult to customize than F5, for example. They have custom iRules that you can write for customized situations. I would like to see more integration for… more »

What's my experience with pricing, setup cost, and licensing?

We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.

Which solution did I use previously and why did I switch?

We used Windows Network Low Balancing.

What other advice do I have?

You need to have somebody who understands application delivery controllers and all their features. If you don't have someone, I would highly recommend training in professional services to help out… more »

What is most valuable?

NetScaler MAS centralised management and analytics makes it is easy to support, manage, monitor, and maintain a NetScaler solution.

How has it helped my organization?

* 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.

What needs improvement?

It should offer more flexible cost-effective licensing for small to medium sized organizations i.e. a pooled licensing option on entry level MPXs like 5901s.

What is most valuable?

As an architect, I have deployed it in so many areas. Some like to use the SSL portion of it, others, they use the load-balancing. It does a lot more than what people use it for. The one feature that… more »

What needs improvement?

The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and… more »

What's my experience with pricing, setup cost, and licensing?

It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what… more »

Which solution did I use previously and why did I switch?

It's not that I have used other solutions, it's just that in most environments where I have had to do my job or to come up with solutions as a solutions architect, the preferred technology was… more »

What other advice do I have?

Every product keeps improving every day and every year. The reason this has been a big technology piece in most data centers is because of the uniqueness of what it does. It's a beast of a technology… more »

What do you think of Citrix ADC?

What is our primary use case?

Provides secure remote access to, as well as intelligent load-balancing for, internal resources.

How has it helped my organization?

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

What is most valuable?

I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production.

What needs improvement?

The policies on the NetScaler can be a bit tricky at times.

For how long have I used the solution?

More than five years.

What is most valuable?

Content Switching since it provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature.

How has it helped my organization?

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.

What needs improvement?

Development team's response time could be better.

Which solution did I use previously and why did I switch?

We had a mix of makes/models, as we supported a large customer base, such as F5, Cisco CSS. We have never had a case where we had to switch NetScaler out for another make.

What other advice do I have?

I would rate NetScaler as a seven out of 10 for good technical support on routine issues, but any issues that needed the development team's involvement took a long time. If you don't have very specific requirements such as the ASM that F5… more »

What do you think of Citrix ADC?

What is our primary use case?

I implemented this solution for customers who were looking to achieve high-availability and resiliency of their business servers, through load balancing.

How has it helped my organization?

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

What is most valuable?

Load balancing Netscaler Gateway

What needs improvement?

Some configuration processes like disabling LB VIPs, automatically disabling the IPs used.

For how long have I used the solution?

Three to five years.

What do I think about the stability of the solution?

No stability issues. Provides great performance.

What do I think about the scalability of the solution?

What is most valuable?

HTTP analysis and action. We have a lot of custom web applications that sometimes require custom header insertions. Some of these custom apps are external and, via the Content Switching, we can use one IP and leverage various back-end web app servers.

How has it helped my organization?

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… more »

What needs improvement?

For the most part, I don’t have complaints about the system and its solution. One of my prior gripes was that documentation and knowledge base articles were disjointed and/or were not complete. Citrix has done a great job over the last two and a half years of enhancing their support material.

What other advice do I have?

I would give the product a nine out of 10. The product is solid and truly is a Swiss army knife. However, getting to use some of the advanced tools, even with the assistance of Citrix support, can be challenging.

What do you think of Citrix ADC?

What is our primary use case?

Load balancing Application gateway SSL offloading

How has it helped my organization?

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

What is most valuable?

Load Balancing and SSL offloading are key features.

What needs improvement?

The GUI should be improved.

For how long have I used the solution?

One to three years.

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… more »

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… more »

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… more »

What other advice do I have?

I would rate the NetScaler a nine out of 10. It is a fantastic platform to work with and the features/functionality are top-notch. The only ding would be for the documentation, but the user community is fantastic.

What is most valuable?

The NetScaler Gateway has been extremely valuable for many reasons. We make use of the load balancing capabilities, including SSL offload and GSLB for high availability. The MAS integration for HDX Insight has provided teams with significant visibility into network performance of the user's connection.

How has it helped my organization?

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… more »

What needs improvement?

Citrix has made steady improvements over the years. Personally, reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement.

What is most valuable?

The most valuable feature would be the Citrix permanent server. It is cost-effective, if you consider the permanent server. Also, the management is easy with no downtimes.

What needs improvement?

There are some features which are missing. What I am looking for is something like OneDrive. We are facing an issue with OneDrive on the XenApp and XenDesktop. We can't use OneDrive with what we have. So, a fully, operational OneDrive… more »

Which solution did I use previously and why did I switch?

I have been working with Citrix technology for the last 10 to 13 years. We have not switched solutions during this time.

What other advice do I have?

We are using Citrix XenApp and XenDesktop, but we are planning to now expand into the same product. Most important criteria when selecting a vendor: * Cost * Performance * Stability * Scalability * High availability.

Which other solutions did I evaluate?

Currently, we are evaluating the cost prospective from the BDA cost prospective. We are evaluating Microsoft and Citrix as they are the leaders in this solution. If you compare Citrix and Microsoft RemoteApp, Citrix is the best compared to… more »

How has it helped my organization?

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… more »

What needs improvement?

I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand.

What's my experience with pricing, setup cost, and licensing?

It all depends on the features that will be used and the number of accesses.

Which solution did I use previously and why did I switch?

No, the whole solution is based in Citrix technology.

What other advice do I have?

It is important, almost crucial, to have some network knowledge. Have the technical design made, it is very simple to overcomplicate when using this product.

Which other solutions did I evaluate?

No.

How has it helped my organization?

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

What needs improvement?

Scripting and writing expressions need to be improved by putting logic behind the rules and improve policies involving some of the scripting part, which is a tedious task… more »

What's my experience with pricing, setup cost, and licensing?

Costly product and complicated licensing.

Which solution did I use previously and why did I switch?

I worked with KEMP and NetScaler.

What other advice do I have?

What do you think of Citrix ADC?

I spend a lot of my time breaking down the different models of Citrix NetScaler appliances and different Software Editions within the Citrix NetScaler portfolio. I decided to set up a blog about this since the path is usually pretty much (lengthy but) the same. This does not mean the answer is always easy because there are a lot of questions that need to be answered. The first thing I would like to get off my chest is the following: Stop seeing/selling the Citrix NetScaler as a replacement for Secure Gateway. It is so much more than that. I often have discussions with various engineers and consultants telling me that Citrix NetScaler is so expensive for a Remote Access solution because Secure Gateway always used to be free. No offense but a Citrix NetScaler solution…

What do you think of Citrix ADC?

Valuable Features:

Does great job on most ADC functions: load balancing, SSL offload, responder policies, etc

Room for Improvement:

10.0 version has been buggy. We've had to patch multiple times and had a production outage trying to do App Firewall learning mode.

Other Advice:

Overall I would recommend Citrix NetScaler, just be careful with newer versions of the code.

What is most valuable?

Citrix main strong-point is its flexible deployment model, which can help customers save on acquisition costs at the onset. The TriScale architecture that the Citrix sales guys have been pushing provides a pay as you grow deployment model. It also allows us to consolidate devices with features such as multitenancy and clustering. Other features like SSL offload for 2048-bit and 4096-bit key… more »

What needs improvement?

It is somewhat frustrating that there has been less feature innovations from their products. Though I really believe that Citrix’s TriScale architecture is a very innovative and successful strategy, it still lacks features such as asymmetric web content optimization which is an essential for ADCs. Also, the use of templates for ease of configuration and use also makes it a somewhat inflexible… more »

What other advice do I have?

I worked with Netscaler in my previous company. Overall, I recommend it. Its innovative TriScale architecture and SSL offloading capability are on par with some of the best products available. It’s a very user-friendly system that is easy to configure and use for a variety of deployment scenarios

What is Citrix ADC?

Citrix ADC is an application delivery controller (ADC) that accelerates application performance, enhances application availability with advanced L4-7 load balancing, secures mission-critical apps from attacks and lowers server expenses by offloading computationally intensive tasks.
