RonaldoDE Melo - PeerSpot reviewer
Protects connection and servers from direct access with control access feature
The initial setup is very simple. The issue is that it achieves high output across all its features, specifically the output ports. This affects the customer's solution because sometimes, the customer is even aware of the user's activity on certain servers. If you have all the necessary information, we can quickly deploy the solution within two to three days. The size of the Thunder ADC depends on its configuration. For example, the cache converter typically includes more than two rack units, often requiring at least three rack units for adequate space. I rate it a ten out of ten, where one is difficult, and ten is easy.
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

"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."
"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 ADCs are pretty straightforward and easy to use. There is a GUI base where you can go in and see everything, but they also have a CLI base where you can use a command and get the information that you want, very fast."
"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."
"Compared to F5, which I used about six years ago, the A10 is much easier when routing. You don't have to use the wildcard bits to route it between the different segments. It's much less troublesome to configure."
"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"The Global Server Load Balancing (GSLB) is simple to use."
"The Deterministic CGNAT feature is valuable for us."
"Citrix Director has been great. It gives us one pane of glass to be able to monitor what's going on with the user sessions as well as to keep on top of the virtual desktops, any servers that may be offline or behaving suspiciously, or any troublesome spots like disconnections. We also use Citrix Studio for maintaining the actual servers that are hosting these applications. We use it for delivery groups in case we need to modify delivery groups in regards to which groups have access to which applications. It has been very helpful."
"Most of the functions are user-friendly and great."
"Very stable."
"I like the solution's simplicity compared to Citrix's on-prem solutions."
"I found that the GUI was very easy to to navigate. If you were looking for something, it was fairly easy to find. There's a lot of third-party documentation and information available online as well."
"The program is easy to install and to set up."
"The stability is good. If there is a problem, the load will be shifted to other sites automatically, which has been a good experience for us."
"Just one solution can handle thousands of users... So, it is a very convenient tool to use."
 

Cons

"The interface and integrated custom applications can be a bit difficult."
"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 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."
"The user interface is not as pretty as it could be."
"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."
"They need to make the user interface (GUI) a bit more usable and intuitive. Some features can be a little difficult to find at times. Sometimes, the workflow in the GUI doesn't match the workflow of an actual workflow. E.g., if I want to create a load balancer application, sometimes you've got to do things a bit out of order in the GUI in order to make it work right."
"The costs can be quite high."
"The tool's load-balancing feature should improve."
"Its GUI should be improved. Its CLI is powerful, but GUI needs more features."
"Citrix ADC can improve if it provides a more user-friendly interface and clear working protocols. Citrix is not working with classic RFC, it is working with Citrix RFC, which is not common in the world. If engineers of Citrix can provide us with more information on working with the classic IP networks it would be a benefit."
"I think the documentation should be improved."
"Currently, it is not easy to use the configuration capabilities of the product."
"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."
"Does not include security. A web application firewall would be a nice addition."
"Citrix ADC can be really complex. It isn't very simple like some other appliances that I've worked with. You need a lot of skill and experience to manage it. I'm not talking about a year or two. You need at least four years to understand it very well. It is not that easy to learn. They should make it a lot simpler for users to understand the management of it. They can also provide some additional training. The material they have on the site is not sufficient enough for you to understand how to manage it. Their training is expensive, and not everyone has the funds and experience for it. Citrix isn't very popular around these parts of the world. So, it can use some more marketing, sales, enlightenment, and advertisement. These could bring more market for them. Basically, there are just a few companies that really go for Citrix. Most of the companies go for VMware because they marketed themselves more than Citrix. There isn't much difference between Citrix and VMware. VMware is a little more robust than Citrix. Citrix has focused more on desktops rather than server virtualization, and that's the advantage VMware has over Citrix. Citrix also needs to educate and inform users about the infrastructure that is supported with a version. Currently, if the customers don't look at the datasheet, they might miss this important information."
"The interface could be improved, some customers struggle with that."
 

Pricing and Cost Advice

"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."
"The price of the maintenance support is too expensive."
"The price is good they are very comparative."
"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."
"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 solution costs less than its competitors."
"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."
"You get a lot more for your dollar with A10."
"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."
"The tool is cheap."
"You get the value for your money. There aren't any hidden fees."
"NetScaler does the same thing as an F5 and it's cheaper."
"This product is more expensive than some of the competitors."
"We have all the features and functions of Citrix because we have a premium license."
"You can do CapEx and then a yearly monthly fee, or you can do a subscription model, whether that's one month, month-to-month, or three-year subscription model."
"Price-wise, I feel that the solution is a little bit expensive."
