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.

Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

Quotes from Members

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

Pros

"Our clients appreciate that this is a security enabled solution."
"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."
"Easy, user-friendly setup with content switching and integrated caching features."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"High availability, performance, and security are the main pillars. It enhances the security for accessing the applications."
"Unified Gateway allows me to provide secure external access to applications for suppliers and customers while requiring Multi-Factor Authentication."
"The load balancing feature of this solution is very good."
"The most valuable feature is the SSL VPN."
"We use the product for load balancing and as a reverse proxy solution."
"Allowed secure access to authenticated user not on the network without having to download client side software."
 

Cons

"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"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."
"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."
"The SLB could be better, and they should improve it."
"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."
"An area for improvement in Citrix Web App and API Protection is for it to give real-time notifications and alerts. It would be practical if the solution warns you if there's an attack or if the load or traffic volume increases or decreases. An additional feature I'd like to see in Citrix Web App and API Protection is a prediction or artificial intelligence on what is happening, for example, attacks."
"In terms of what could be improved, I would say the user interface because sometimes it can be complicated."
"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."
"We have issues with the certificates. All authorization processes need certificates, however, every three months we needed to change certificates. This process iss complicated for us because Citrix does not have a not user-friendly interface and does not off user-friendly services. This needs a lot of improvement."
 

Pricing and Cost Advice

Information not available
"Citrix ADM costs us approximately $5000 per month."

"It all depends on the features that will be used and the number of accesses."

"The solution is undoubtedly very good, but it is expensive."
"The licensing costs for this solution vary depending on which model is being used."
