Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

I'm researching Application Delivery Controllers. Is Citrix ADC the best option? If not what are the shortcomings and which products do a better job?

There are a few questions.  What is the problem you are fixing with the ADC?  Is there a reason or application that makes you want to lean towards Citrix versus another vendor?  Second, as mentioned by others, most ADCs will do L4-7 load balancing.  So the questions to differentiate is how easy is it to learn/configure, how easy is it to maintain/operate on a day to day basis, and how expensive will it be over its functional life?

Most organizations do not want to have to hire a load balancing specialist that is tied to a specific vendor because of complexities and custom programming languages.  They also want something that is easy to manage for the operations team with minimal training and expertise.  They also are looking for a vendor that can provide stellar and timely support through their 24/7 support organization.  All of these things will drive down the operational costs and when tied with the capital investment, I would consider broadening your net and look at other vendors.

Personally, I would recommend Kemp, but I am biased, being a current employee of the company.  But I have been in the load balancing industry for over 20 years with multiple technologies and vendors and I believe that if you look at all of the facts, you will make the proper and logical decision.  Good luck with the project!

If you are only looking for leading L4-L7 load balancing features, go for Citrix ADC as it is much easier with the GUI and writing Traffic policy is much much easier with GUI app expert syntax - What you see is what you get. Easier to transfer complex admin tasks/rules to another team or Colleague.

F5 also provide leading L4-L7 load balancing features but F5's GUI is not as easy and compact as Citrix ADC. Some commonly used menus that should appear next to the main topic are hidden and you have to drill down too much just to configure simple tasks.

With F5 iRule you need to write some basic iRule coding with correct syntax {asd{asd a}adsas } which could be complex and hard to transfer to another team or Colleague.

(it's not that hard but more learning curve and more point to get error with the syntax)

Citrix ADC also provides free SSL VPN from STD:500, EE:1000, Platinum: Unlimited. 

And also free ICA proxy for Citrix Virtual Apps and Desktops from external network.

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.

I would advise others to just go through and look at the requirements and the needs of the people you're supporting. I will always recommend doing a POC, just to make sure that the product that you're inquiring about or thinking about purchasing does what it says it does because you don't want to be oversold something and it under-delivers. I will always recommend doing some type of POC to test everything out. If it is in your budget, then I would say go with it. It has improved the way our organization functions. I have been very impressed with the direction in which Citrix is going. I got introduced to Workspace last year, and I attended the virtual SYNERGY conference. It was very impressive to see so many upcoming things that Citrix is working on. I noticed that VMware also has its version of Workspace, so I guess that's the new hot terminology to use. The Citrix solution is called Workspace, and the VMware solution is called Workspace ONE. I would rate Citrix ADC a nine out of ten. There's always room for improvement for any application. That's why they have different versions or a series of applications.

Today I use Fortinet for both VPN SSL and WEB SSL. I'm considering returning to Citrix (Netscaler) but the products have changed so much that I no longer know what each one is for. Is Citrix ADC a good solution for web app firewall? App delivery management? Gateway? There are so many out there, I'm not sure which is right. Fortinet seems to be used more by communications people. Citrix seems m...

Citrix and is one of the leading product holders in the SSL VPN. l would recommend CITRIX because of its better load handling as well as CITRIX has an onboard SSL decryption chip which reduces the decryption load from the processer which provides us optimal speed and maximum production.

I'm a Citrix Engineer and I supply CITRIX products to companies in Korea. Both products are excellent in my experience. So I will give you some data for Compare Citrix WAF with Fortinet WAF In my opinion, Fortinet has a lot of experience as a security device, so I think WAF is equally fine.
