A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"High availability, performance, and security are the main pillars. It enhances the security for accessing the applications."
"The web application firewall which protects our services on the internet, and then of course services like our ability to provide high availability for the services we are offering are the most valuable features."
"It is a very stable solution."
"We use the product for load balancing and as a reverse proxy solution."
"Content Redirection and SSO integration with Citrix XenApp/XenDesktop. The GUI was wonderful."
"Its customer support service is good."
"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."
"Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... 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.)"
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"The setup for Citrix NetScaler has room for improvement. It could be easier."
"Citrix should improve the documentation. It is not really clear how to set up many features to our advantage. When we setup Citrix NetScaler ADC, we have to figure it out by ourselves without a lot of documentation."
"The security is okay, but the monitoring and reporting need improvement."
"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."
"There are some features which are missing.​"
"The solution's pricing is a big concern and should be improved."
"The solution is a bit more expensive than some of the available solutions in this region. One solution in particular that I noticed was cheaper was Kemp."
"The product provides some templates to integrate with applications like MS Exchange, MS SharePoint, SAP Enterprise Portal, and others. However, the last update for these templates was 2013 (lots of applications are running on versions newer then 2013)."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
"Its price is comparable to others and affordable."
"We get value for money. Its price is fair. I don't think it is overpriced."
"Regarding pricing, while it's expensive, I can't comment on the exact ROI without a budget analysis. However, in terms of service quality, it's worth the price."
"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
"The pricing for Citrix Web App and API Protection is unreasonable. I don't know the exact price, but I heard it's tens of thousands and it's a bit too much for the small country I live in."
"I do not have any experience with the pricing of the product."
"When compared to other solutions, the cost is high."
