We performed a comparison between Citrix NetScaler, F5 BIG-IP Local Traffic Manager (LTM), and NGINX Plus based on real PeerSpot user reviews.
Find out what your peers are saying about F5, Citrix, HAProxy and others in Application Delivery Controllers (ADC)."The flexibility in configuration options is impressive."
"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."
"The load balancing is one of the most valuable features."
"It is a very stable solution."
"It is the best product out there."
"The solution is easy to work with and manage."
"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."
"The feature that I have found most valuable is its load balancing."
"The main reason that we suggest this product to our clients is the great integration with other security tools, such as IBM Guardium."
"Stable and scalable network traffic management solution for applications. It has good performance."
"LTM."
"It offers features Kemp doesn't provide. For example, there are predefined templates for handling Office 365. You can download them for automatic configuration."
"One of the best features of the solution is the operating system."
"Bandwidth optimization and capacity awareness of the bandwidth are valuable features. Its video streaming capabilities are also very useful."
"I like that F5 BIG-IP Local Traffic Manager (LTM) is a product that comes with valuable features, but what stands out from all features is load balancing."
"The solution could improve the ease of use, the management could be simplified. Other solutions are easier to use."
"Application Gateway with application-level firewall tool and load distributor and balancer (also serves for A/B testing)."
"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."
"NGINX Plus' most valuable feature is the ingress controller."
"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."
"Using NGINX Plus for web traffic distribution is fantastic. It offers performance similar to physical load balancers but with added flexibility."
"The web proxy and the database proxy are excellent."
"Zero Downtime has always been a strength in recommending infrastructure web services. NGINX allows me to execute such infrastructure with less complications and the ability to switch from server to server easily."
"Its versatility and capabilities make it invaluable for implementing patches and fixes when necessary."
"Native integration needs to be improved. You cannot build ISE codes natively. For DevOps, integration would be very helpful because it would be a lot simpler from an operational standpoint."
"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 you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified."
"Integration with other third party providers and third party applications could be better because it can be a bit complex at present."
"There are some features which are missing."
"Quality assurance could improve by ironing out security vulnerabilities before releasing upgrades."
"If one device or switch fails, the failover to another device is not seamless which is painful."
"Citrix NetScaler has been recently acquired by another company and the support has been negatively impacted, the solution is at its end of life. The support for the solution could improve. The sales team needs to be improved."
"Should offer more flexible cost-effective licensing for small to medium sized organizations."
"To improve the product, they could add more load balancing solutions in Kubernetes."
"The user interface of F5 BIG-IP LTM is old and could improve."
"Reporting could be improved and configuration made easier."
"LTM would be improved with the inclusion of signature-based blocking."
"They need to develop the reporting tools further."
"We need best-practice information. They have something called DevCentral and a blog. But we want something from F5 itself regarding how to tackle the false-positive configurations. If you go into detail with so many configurations it will find so many false positives from the moment it is enabled that it will quickly impact your applications, and it will not work."
"In terms of native integrations, there is a lot of instability. Also, integration is not robust with F5."
"They could improve the product's ease of use. There is some confusion how to operate it."
"The drawback is that you must obtain a license for everything."
"The solution needs to be easier to setup and deploy."
"If NGINX brings some features for health check in the open source version, it would be better. "
"Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun."
"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. "
"The KPI should be more focused on load balancing and the latency in application calling from the end system."
"The solution's GUI is an area with certain shortcomings that need improvement."
"Improvement needed in NGINX Plus could focus on optimizing memory usage for users."
