We performed a comparison between A10 Networks Thunder ADC, Citrix NetScaler, and F5 BIG-IP Local Traffic Manager (LTM) 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 Deterministic CGNAT feature is valuable for us."
"We have two appliances and I'm able to move my application from one appliance to another. I don't have to move my whole A10 to be active on the other side or to be passive on the other side. If an application is having a problem, I can just move it using a command."
"The Global Server Load Balancing (GSLB) is simple to use."
"It's a very friendly solution, easy to configure and it's very flexible."
"A10 explained why the latency dropped significantly on a site that we have."
"Being a public entity and having a public website which is highly visible with a lot of traffic, we are a target for DDoS. Within the last year, we have had a couple of DDoS attacks which could have affected our web traffic and taken down certain parts of our website. This did not happen because the A10 was able to mitigate the attacks using rate limiting that can be configured for DDoS mitigation on the box."
"A10 Networks Thunder ADC is an easy-to-use and flexible solution."
"The DNS application firewall and load balancing are very valuable."
"The solution is very stable. We don't have any downtime or issues of that nature."
"I would say the rewriting and redirection functions are must-have's for us."
"The NetScaler appliance has provided a lot of customers with greater high availability for their enterprise applications within a single site and across multiple locations."
"The most valuable features are the VDA Delivery, Gateway Fort, and the load balancing."
"Load Balancing and SSL offloading are key features."
"I find all of it to be valuable, because of the flexibility that is built into this product."
"It is a complete solution for those looking for an all-in-one."
"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."
"It is a fast and available solution."
"The solution could improve the ease of use, the management could be simplified. Other solutions are easier to use."
"It is a very good, flexible solution. It helps us to catch up on flaws in our partner solutions on top of its load balancing feature."
"F5's attack signatures and automation are the most valuable features. The disaster recovery capabilities are also excellent. You don't need to do anything. It has automatic failover from production."
"It supports APIs and virtual additions for cloud and VMware."
"F5 has many capabilities for load balancing and web application firewall features."
"The combination of ADC and WAN is the most valuable feature."
"It integrates with AWS WAF, which makes it easy to deploy without changes to your infrastructure."
"We are starting to do a lot with containers and how the solution hooks into Kubernetes that we haven't explored. I'm hoping that they have a lot of hooks into Kubernetes. That would be the part for improvement: Marketing use cases with containers."
"The costs can be quite high."
"The solution should add automation features in the next release."
"When it comes to support, there is always room for improvement. First call resolution is not always there for urgent issues. The first call resolution is something that could be improved upon."
"There is two-factor authentication built-in, but it could be more robust."
"The interface and integrated custom applications can be a bit difficult."
"A10 Networks Thunder ADC could improve on the Application Delivery Controller. it's not a fully-fledged web application firewall solution. For example, application data and support need to improve."
"Traffic flow issues are very difficult, as there's no means for us to analyze the traffic coming in or out of the appliance without technical support."
"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."
"Overall the price of Citrix ADC could be more competitive."
"The licensing model and technical support of the solution could be improved."
"Mastering it requires significant learning and training due to its complexity."
"We face challenges with the solution's firmware upgrades frequently."
"We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers."
"There are some features which are missing."
"The technical support could be improved. They do not respond or assist customers in a timely manner."
"The price for F5 BIG-IP Local Traffic Manager is very high. This aspect could be improved."
"Technical support could be faster. It's something I'd like to see them work on in the future."
"The initial setup can be complex - it's quite flexible in terms of configuration, but the person configuring it needs to understand the application side, the network side, and the server."
"The cost of the solution is pretty high. It would be ideal if it was more reasonable."
"There are some aspects of F5 BIG-IP that could be improved, the main one being virtual machine support. We have seen that even with the virtual editions, there are some things that we would like to do that are currently not possible with virtual machines."
"Needs to provide a visual interface to follow a customer's activity (from client to BIG-IP to SNAT IP to the chosen server, then back). Today, we are still performing packet captures."
"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."
"F5 BIG-IP LTM can improve on the SSL loading which includes the authentication of certificates. Although, most of these issues have been solved there are still some issue that persists."
