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

"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."
"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."
"Our clients appreciate that this is a security enabled solution."
"We appreciate that this solution facilitates our access to Citrix internet."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"It has helped us to increase the resiliency of the application and the performance."
"The most valuable feature, absolutely, is its high-security."
"We have Citrix StoreFront to access everything from a remote desk, and we use it with Office 365 so that we can access Teams."
"The most valuable feature of this solution is that it is very light, and once you log in, you have your applications delivered, and my customers have told me that the performance of this solution is good."
"The most valuable feature of Citrix NetScaler was the seamless integration. Additionally, the UI is good."
"Its innovative TriScale architecture and SSL offloading capability are on par with some of the best products available."
 

Cons

"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"The support from A10 should be improved."
"The initial setup was complex."
"I think the documentation should be improved - there should be more documentation."
"The reporting is not so good. They don't have an application to connect the logs."
"Development team's response time could be better."
"Some of our customers have questioned the security of this solution lately, wondering whether it is safe or not, so enhancements in this respect would be good."
"The technical support has room for improvement."
"The product provides some templates to integrate with applications like MS Exchange, MS SharePoint, SAP Enterprise Portal, and others. However, the last update for these templates was 2013 (lots of applications are running on versions newer then 2013)."
"It can be a complex setup in some cases."
 

Pricing and Cost Advice

Information not available
"For partners, NetScaler is not as expensive price-wise versus F5."
"The pricing could be lower."
"The license for Citrix NetScaler is on an annual basis and it is reasonably priced."
"NetScaler does the same thing as an F5 and it's cheaper."
"Its licensing cost is much higher than other products, but it is acceptable because it is a one-time investment, and we are getting our requirements fulfilled when we buy this product. So, there is no issue with the pricing."
"It's an expensive product but it works well."
"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
