We performed a comparison between Citrix NetScaler and HAProxy 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."We use the solution's IP Reputation and bot protection features."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"The web application firewalling component is a powerful feature."
"Global load balancing between data centers."
"We appreciate that this solution facilitates our access to Citrix internet."
"One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low."
"My customers have told me that the performance of this solution is good."
"The solution was very easy to deploy."
"It reduced the load on our main load balancers."
"The anti-DDOS PacketShield filtering solution (embedded in the physical appliances) as well as the BGP route injection are great features and heavily used."
"HAProxy's TCP load balancer is excellent and super stable."
"It is scalable."
"The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."
"Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced."
"HAProxy Enterprise Edition has been rock solid. We have essentially had no downtime caused by our load balancers in the last 10 months, because they’ve worked so well. Previously, our load balancers caused us multiple hours per year in downtime."
"It is stable. Period. Will not fail unless you do something wrong."
"The technical support has room for improvement."
"If one device or switch fails, the failover to another device is not seamless which is painful."
"Quality assurance could improve by ironing out security vulnerabilities before releasing upgrades."
"The solution could be more secure."
"Scripting and writing expressions need to be improved by putting logic behind the rules and improve policies involving some of the scripting part, which is a tedious task to do."
"Maybe creating policies with simple regular expressions."
"I feel that Citrix NetScaler's customer support needs to improve."
"The tool needs to add a feature where we can access the network policy access manager."
"Dynamic update API. More things should be possible to be configured during runtime."
"While troubleshooting, we are having some difficulties. There are no issues when it is running; it is stable and very good; however, if there is a troubleshooting issue or an incident occurs, we will have issues because this is open-source."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit"
"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading. Also, it would be helpful if I could logically divide the HAProxy load-balancing into multiple entities so that I would install one HA Proxy LB application which could be used for different Web servers for different applications. I am not sure if these features are available."
"Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading."
"It needs proper HTTP/2 support."
"Pricing, monitoring, and reports can be improved."
"The product does not have any new technologies."
