SatishBabu - PeerSpot reviewer
Known for its load balancing capabilities, the WAF features need to be improved
The solution's initial setup process was easy. For the installation, it takes around five minutes. One person can do the maintenance since it is not required much. So, it's a one-time solution, and its maintenance is fine. The number of people required for maintenance depends on the clients as well. One or two engineers are fine to serve around a hundred clients. If you have a number of devices, more people are needed for their maintenance because of the patching it requires during regular operations. Only for the maintenance, one engineer's fine. However, for regular operations, we need multiple people.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It helps with the efficiency of application deployments and data security."
"It's a very friendly solution, easy to configure and it's very flexible."
"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 solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"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."
"The Global Server Load Balancing (GSLB) is simple to use."
"A10 Networks Thunder ADC is an easy-to-use and flexible solution."
"The DNS application firewall and load balancing are very valuable."
"The web application firewall is one feature I found valuable in the solution."
"Content filtering, security layer, and application customization features are the most valuable."
"When our primary link goes down I can still get to my Cisco devices and the NetScaler devices on-prem because of the SDN solution. If the internet connection at one of the branches goes down, we can still route them, they still get internet based on the SDN solution through one of the other sites. They can carry on working."
"The most valuable feature of Citrix ADC is its ease of use."
"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."
"This solution allows the user to easily scale out application delivery, and provides secure remote access."
"It is simple for both IT specialists and customers."
"The solution is extremely stable."
 

Cons

"I would like them to provide learning tips and a community forum where users can share ideas. They need more detailed support articles on the A10 website."
"The user interface is what people complain about most of the time, particularly if they don't use it very often. Then they complain that it's a bit clunky."
"The costs can be quite high."
"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."
"The setup depends on certain situations. In certain scenarios, it may be more complex than others. For example, while the initial configuration may be easy, the environment itself may be complex and that may limit the ease of deployment. It is easy for those who understand their environment."
"A graphical dashboard for analyzing performance is needed."
"There is room for improvement in the GUI. I just migrated from the 2.7 software train to the 4.1, and there are still people on 2.7. The latter is a very old GUI if you compare it to F5. It's not as easy to use and a lot of things are missing. They've made a lot of improvements in the 4.1 step, but compared to the ease of use of F5, it's still quite difficult. For people who haven't got a lot of experience, the GUI can be quite challenging."
"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."
"There are some features which are missing.​"
"An area for improvement would be the difficulty in finding information about standard licensing costs over the internet. They should provide some reference prices on the net to be quickly referred to."
"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."
"I think the documentation should be improved."
"The security is okay, but the monitoring and reporting need improvement."
"It can be difficult to setup."
"Quality assurance could improve by ironing out security vulnerabilities before releasing upgrades."
"They can improve the scalability and the multi-tenancy feature. We recently tried to configure an authentication, and we ran into some issues while using the web-based GUI. It was very slow when you log in with your credentials in the web-based GUI. Each time we clicked on the menu, it tried to do the authentication. It works properly in the console."
 

Pricing and Cost Advice

"Pricing is one of the features of the product that influence customers to use the product."
"The price is good they are very comparative."
"It is $7000 per unit for the support annually."
"The pricing is fine, considering the features they are providing. If you are an individual user, they'll price the product differently compared to how they price the product that is sold to an organization."
"There were budgetary constraints that keep us from investing in the single pane of glass traffic management feature. We saw a demo of this feature about a year to a year and a half ago."
"The price of A10 Networks Thunder ADC depends on capacity and the customer's requirement. They have several offerings. They have different price models and options to choose from. Additionally, you need to subscribe to support for the hardware appliances."
"We did try out the solution’s Harmony analytics and visibility controller for its one-year trial. Due to the cost, we chose not to keep it onsite."
"For the hardware and license, we paid $35,000 per box, which was a one-time cost. Then, for the Gold Support on the two boxes, we pay $9400 annually."
"The price for Citrix ADC here in Mexico was good, when you compare it with F5 and Radware."
"The pricing for Citrix Web App and API Protection is unreasonable. I don't know the exact price, but I heard it's tens of thousands and it's a bit too much for the small country I live in."
"Regarding pricing, while it's expensive, I can't comment on the exact ROI without a budget analysis. However, in terms of service quality, it's worth the price."
"The license for Citrix NetScaler is on an annual basis and it is reasonably priced."
"There isn't much of a difference between the cost of Citrix and that of other similar solutions."
"Citrix ADM costs us approximately $5000 per month."
"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."
"The client pays for the Citrix NetScaler license annually."
