Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is the SSL VPN.""I can turn on features without actually owning a license. I can test them out, I can use them for a while, and then I can be licensed up. That's awesome. I don't have to have a license immediately before I can start to deploy things rapidly, rapid deployment is a plus.""The program is easy to install and to set up.""Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature.""My clients use it for load balancing.""The MAS integration for HDX Insight has provided teams with significant visibility into network performance of the user's connection.""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.""The load balancing feature and the fact that you can do context switching in the WAF are the most valuable. We majorly use it for load balancing, but we also use it for context switching in the WAF. It is also robust and very easy to work with and manage."

"Its most valuable features are load balancing and application delivery. This is the most efficient application for these features because of stability and its efficiency.""With NGINX, I appreciate its ability to route traffic geographically.""Nginx is simple to configure, very stable in a highly utilized environment and very modular, allowing DevOps to create it's own modules for interactive use with Nginx.""The load balancing module, which is equivalent to LTM, is the focus of the PSE. So far, the features of both are identical. I believe NGINX has more features for securing these services, but in terms of load balancing, both are massive solutions.""​The flexibility of its modules allow it to be scalable.​""The most valuable feature of the solution is that it is simple to configure.""It's lightweight software that can handle heavy loads efficiently.""Supports IMAP, POP and SMTP protocols for the reverse proxy."

Cons
"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 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.""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).""If one device or switch fails, the failover to another device is not seamless which is painful.""I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises.""Technical support could be improved.""The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though.""Too many bugs in the software and it's always difficult when you need to update."

"It would be good if NGINX provided a graphical user interface.""NGINX Plus is moderately priced, but it could give better value for money.""They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing.""Make modules easier to enable or disable. The beauty and ugly side of the NGINX modules is you have to know how to compile the module. For beginners or non-very technical aspirant(s) going for NGINX, they have to learn how to compile the modules.​""Improvement needed in NGINX Plus could focus on optimizing memory usage for users.""The biggest room for improvement would be to allow NGINX Core machines to cluster for memory zones in some way with a plug and play module. ​""Lack of a feature to print data on the terminal for verification of network traffic during debugging and testing.""The KPI should be more focused on load balancing and the latency in application calling from the end system."

Pricing and Cost Advice
  • "It's not for startups or SOHO."
  • "Costly product and complicated licensing."
  • "It all depends on the features that will be used and the number of accesses."
  • "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 NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
  • "We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
  • "We are quite happy with price. It's not too high."
  • "I do not have any experience with the pricing of the product."
  • "You get the value for your money. There aren't any hidden fees."

  • "Nginx is free. I don't have experience with the Plus version."
  • "I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it."
  • "​NGINX Plus is worth it, if you need it. If you do not need the features or support, the free and open source package is more than capable. ​"
  • "​NGINX is a free tool in Brazil. There are some companies which do support it.​"
  • "The price is the cost to contract support with a specialized company, usually during consulting hours.​"
  • "Compared to other similar solutions on the market, I think it's over-priced."
  • "You pay for each feature that you want."
  • "The list price of NGINX Plus is close to $5,500."

    Reviews from Real Users

    Citrix NetScaler is a solution that stands out when compared to many of its competitors. Some of its major advantages are that it is easy to use, is robust, and has good load balancing.

    A Senior Citrix Engineer at Troye, says, “The web application firewalling component is probably the most powerful feature as it can identify attacks on the network at an application level which is quite important. There is also good functionality where we use IP reputation and geofencing to mitigate threats from the outside world.”

    “The feature that I have found most valuable is its load balancing,” explains a Security Consultant at a tech services company.

    Timur G., Team Head of Network Security at DOM.RF, writes, “The most valuable feature of Citrix ADC is its ease of use.” 

    Another PeerSpot reviewer, Nirav S., Technical Solutions Architect at MindTree, mentions, "Compared to other solutions, Citrix ADC is much more robust in terms of the native integration to cloud platforms. It is far more robust from an operational point of view as well."

    NGINX Plus is a versatile solution that offers load balancing, caching, proxying, and API deployment capabilities. It can be deployed on private or public clouds and is ideal for building CDN solutions. The solution can also be used to secure web applications and replace web services like Apache. 

    NGINX has helped organizations improve functioning, reduce downtimes, and offer a DevOps-friendly solution. Its community support and documentation are highly regarded, and its configuration is more straightforward, making it a recommended choice over HAProxy.
