I am a consultant and do not recommend specific products. I work with customers, and they decide what they want to buy. I'm a CISO as a service, dealing with security. I'm from an integrator company, and they usually sell a few products. One customer uses NetScaler for a VDI system with Citrix…

Quotes from Members

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

Pros

"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"The solution is simple and powerful. I find the Barracuda Load Balancer ADC's load balancing function most valuable. It balances the traffic well. The security features, like the Web Application Firewall, are also very helpful."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"The price is very good, and it's not very expensive."
"With Citrix ADC, our clients can improve their security, performance, and they can escalate when they need it."
"Easy, user-friendly setup with content switching and integrated caching features."
"The solution was very easy to deploy."
"The installation is simple for both manual configuration and automatic deployment."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"Available on any device and can be accessed on a wide area network."
"Its flexibility, agility, and robustness are the most valuable. Its management and implementation are also quite easy."
"The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications."
 

Cons

"The quality of the solution's performance could be improved."
"We find with WAN optimization it’s a bit unstable but we don't use it for that."
"We find with WAN optimization it’s a bit unstable but we don't use it for that."
"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"The Barracuda Load Balancer ADC could be improved with more customization features. For example, F5 uses iRules for custom configurations. I haven't found something similar in Barracuda yet. The load balancer and WAF's basic and common features are enough, but we need more customization options."
"The quality of the solution's performance could be improved."
"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."
"The policies on the NetScaler can be a bit tricky at times."
"ADC from Citrix has added functionalities from other products and the usability is very difficult for someone who is used to a simpler user interface, it's a little bit of a mess to use."
"Citrix Web App and API Protection could improve in the area of licensing."
"Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used."
"Citrix ADC is a complex product, and it takes time to understand these things. But the documentation is poor, and the deployment is difficult."
"I think the interface could be better. I think some customers struggle with that."
"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."
"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."
 

Pricing and Cost Advice

"Load Balancer ADC is cost-effective and is about half the price of F5."
"I rate the solution's pricing a five out of ten."
"The client pays for the Citrix NetScaler license annually."
"It's not for startups or SOHO."
"Ninety day free trial makes it easy to try out this solution."
"Regarding pricing, while it's expensive, I can't comment on the exact ROI without a budget analysis. However, in terms of service quality, it's worth the price."
"Citrix ADM costs us approximately $5000 per month."
"This product is more expensive than some of the competitors."
"I rate the pricing an eight out of ten since it is expensive."
"We have a yearly licencing fee, and there are no additional costs."
