Efficient application security while optimizing connections
The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.

Quotes from Members

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

Pros

"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"Our clients have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"Our clients appreciate that this is a security enabled solution."
"Deployment of NetScalers on our DMZ enables our organization to implement a secured gateway for our Web Portal, Inbound/Outbound application web service calls across our partners/clients, security, and Traffic Management."
"Just one solution can handle thousands of users... So, it is a very convenient tool to use."
"It has improved my customers' base functionality by providing resiliency to their applications that reside on servers, as well as connectivity to remote applications."
"Global load balancing between data centers."
"The stability is good, and if there is a problem, the load will be shifted to other sites automatically, which has been a good experience for us."
"Citrix is more user-friendly and scalable for engineers for doing configuring."
"It is the best product out there."
"The most valuable feature is the capability of performing load balancing in a virtual environment."
 

Cons

"The support from A10 should be improved."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"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."
"There are some features which are missing.​"
"I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises."
"I would like to see multifactor authentication added to this solution to improve the security."
"They need to make the solution a little more familiar with easy study guides, learning videos, etc."
"Our customers' feedback was that support wasn't the best."
"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 drawbacks, such as using EUG for specific configurations. It could be improved."
 

Pricing and Cost Advice

Information not available
"We have all the features and functions of Citrix because we have a premium license."
"Costly product and complicated licensing."
"Citrix NetScaler's pricing is slightly above average but not overly expensive. I would consider F5 BIG IP to be the most expensive, Citrix NetScaler to be the second most expensive, and then Kemp Load Balancer to be the third."
"It all depends on the features that will be used and the number of accesses."
"I rate the pricing an eight out of ten since it is expensive."
"Citrix ADM costs us approximately $5000 per month."
"I give the price of the solution a seven out of ten."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
