We performed a comparison between Citrix NetScaler and NGINX Plus based on real PeerSpot user reviews.
Find out in this report how the two Application Delivery Controllers (ADC) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Very stable."
"The web application firewalling component is a powerful feature."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"Its customer support service is good."
"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."
"What I like most about Citrix NetScaler is its stability, and I didn't see a lot of issues with it."
"It has helped us to increase the resiliency of the application and the performance."
"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."
"With NGINX, I appreciate its ability to route traffic geographically."
"The robust software architecture allows for it to be scalable and very stable."
"When you use NGINX, you have more options and power."
"NGINX works much better than HAProxy in our current hardware and architecture for HTTP/HTTPS load balancing. "
"When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great."
"The product is resilient."
"The most valuable feature of the solution is that it is simple to configure."
"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."
"We are looking for some in-depth monitoring and analytics and more information that Citrix Director doesn't provide. ControlUp has insights that not only give you an overview but also allow you to do some drill-down troubleshooting for what's going on in your environment. We are looking for some more analytical and monitoring data to be able to monitor the environment better, not only from an application standpoint but also from the standpoint of the infrastructure to everything it sits on. They can provide more data to the administrators about what's going on within the application. They can provide data not only on the application side but also about what the application sits on. They're making strides with Citrix Analytics in regards to that."
"It can be difficult to setup."
"If one device or switch fails, the failover to another device is not seamless which is painful."
"I would like to see support for scripting, like "iRule", which gives you the option to implement any configuration which is not available out of the box."
"Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us."
"The WAF component needs to be simplified so that it is easier to use."
"The solution can improve their support and send tickets directly to a Citrix ADC engineer in order to avoid having to escalate each support call."
"It was challenging explaining to customers that it's no longer NetScaler but ADC, and now it's not just ADC but also the rebranding from NetScaler."
"The solution's GUI is an area with certain shortcomings that need improvement."
"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."
"It would be good if NGINX provided a graphical user interface."
"There is room for improvement in the pricing model."
"They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing."
"I would suggest adding GUI-based configuration panels to NGINX Plus to simplify setup and management tasks."
"NGINX is a very basic load balancer and cannot do as many customizations as F5."
