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.

Easy to set up and has good integration into the host environment but needs better third party integration

I'm not sure which version number we are on. It's one of the latest, I assume. We don't run the latest. We usually are either one or two versions behind. It is something we are exploring. We do have use cases and it will compete against our existing product line. That would have to go in the second half of this year. Right now, it's more of a comparison of how we use it right now. We don't use it really in production. We are going to definitely explore it and do our comparison and more in-depth analysis of the product and compare it against our existing product line. I'd advise potential users to do a very in-depth analysis of the products in comparison. And don't just look at the cover of it - really look into the detailed backend support infrastructure and if it can be implemented the way you need it to be. I'd rate the solution five out of ten. It's not a fully mature product.

Quotes from Members

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

Pros

"From a security standpoint, It is a comprehensive solution in a single box."

"The most valuable feature of Citrix NetScaler was the seamless integration. Additionally, the UI is good."

"The most valuable feature is the SSL VPN."

"Just one solution can handle thousands of users... So, it is a very convenient tool to use."

"Provides resiliency for applications that reside on servers, as well as connectivity to remote applications."

"HTTP analysis and action. We have a lot of custom web applications that sometimes require custom header insertions. Some of these custom apps are external and, via the content switching, we can use one IP and leverage various back-end web app servers."

"It is a very stable solution."

"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."

More NetScaler pros

"Its visibility and login mechanism are the best parts. In addition to the great visibility it has a great dashboard and an easy to configure graphic user interface, a beautiful GUI."

"The friendly user interface is valuable."

"What's most valuable in Avi Networks Software Load Balancer is its deployment capability, the ability to deploy in a dispersed service, with the service engines that can disperse and have a single control plane that can control the load balancing services across any available platform, wherever needed. The analytics of Avi Networks Software Load Balancer and flexibility of deployment are its most valuable features and the reasons why many people buy it."

"The most valuable feature of the solution for my organization is its UI since it allows us to see the clusters while providing a very specific and good overall understanding."

"The solution has simplified our network infrastructure management."

"The WAF - the web application firewall itself - is great."

"The interface and software features are the most valuable aspects of this solution."

"The solution is stable."

Cons

"Citrix NetScaler has been recently acquired by another company and the support has been negatively impacted, the solution is at its end of life. The support for the solution could improve. The sales team needs to be improved."

"When a new version comes out, sometimes, my existing configuration gets wiped out. They should work on this so that my existing configuration doesn't get impacted with an upgrade to a newer version. There could also reduce frequent firmware upgrade activities and have a stable version so that once we upgrade it, we don't have to upgrade it for two to three years."

"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."

"Technical support could be improved."

"Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used."

"I am not an expert in this solution, but simplicity and user-friendly interfaces are crucial for me. I would appreciate advice from Citrix, particularly in the form of an interactive guide for API protection. It would be helpful if they could provide specific points and recommendations for cybersecurity, indicating areas that need attention or improvement. I find such interactive guidance valuable."

"The technical support could be improved. They do not respond or assist customers in a timely manner."

"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."

More NetScaler cons

"The network analytics and monitoring features are not effective."

"I did not go with it because their APM module is a different product altogether. It's a common thing that companies do. They sell something and then they add on top of it as a different product. It is a type of marketing strategy. But when it comes to the overall management, it takes a lot of time to really look into it."

"In terms of improvement, the pricing and documentation need improvement. We have had problems getting the documents."

"IDS and IPS sites need to be more progressive."

"The initial setup is a bit complex."

"Avi Networks Software Load Balancer needs to improve its documentation."

"It doesn't match the development structure or user community of our existing product. It pales in comparison to that."

"One struggle with Avi Networks Software Load Balancer is its integration with other VMware products. Integration could be improved in the solution so that you have a more unified control plane with it and other data center security and networking products that VMware sells. There has been a bit of a lag on the roadmap of new features that have come out there recently, but better interoperability with the hyperscale environments such as the AWS, Azure, GCPs of the world, and simpler deployment and interoperability with those existing tools, are areas that are receiving attention and could use additional attention today. These are the areas for improvement in Avi Networks Software Load Balancer."

Pricing and Cost Advice

"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."

"This product is more expensive than some of the competitors."

"We are quite happy with price. It's not too high."

"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."

"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."

"We have a yearly licencing fee, and there are no additional costs."

"The solution's pricing is very high compared to its competitors."

"I do not have any experience with the pricing of the product."

More NetScaler pricing and cost advice

"The tool is expensive."

"The licensing costs for Avi Networks Software Load Balancer are really variable. The product can be sold from a bandwidth utilization perspective. It can be sold from a per CPU perspective, depending on if you're looking at on-premises or hyperscale environments. Licensing costs vary quite a bit if you're familiar with the AWS Calculator, where you can see that it can widely vary per licensing model. On a scale of one to five, with one being not very good value for the money and five being great, I would rate the pricing for Avi Networks Software Load Balancer a five because its pricing is extremely competitive. Not all features are included with the license, for example, there's single licensing."

"With Avi Networks, you can buy a 10-Gig license and, if your primary data center goes down, in the flick of a switch you can move that license to your backup data center and it will generate the traffic... there are a lot of cost-effective measures."

"I rate the solution price a four to five on a scale of one to ten, where one is low, and ten is high, since it is an affordable tool."
