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.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"Scalability is great. One of the best features of NetScaler is that it can scale out."
"Citrix ADC is highly scalable; you can upgrade it and increase the bandwidth or add more security features, starting from the basic standard version up to the Platinum version."
"Citrix Director has been great. It gives us one pane of glass to be able to monitor what's going on with the user sessions as well as to keep on top of the virtual desktops, any servers that may be offline or behaving suspiciously, or any troublesome spots like disconnections. We also use Citrix Studio for maintaining the actual servers that are hosting these applications. We use it for delivery groups in case we need to modify delivery groups in regards to which groups have access to which applications. It has been very helpful."
"My clients use it for load balancing."
"The program is easy to install and to set up."
"Most of the functions are user-friendly and great."
"It's a wonderful product."
"Its flexibility, agility, and robustness are the most valuable, and its management and implementation are also quite easy."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
"It seems to provide a bit of useful information on website health."
 

Cons

"There is room for improvement regarding the pricing policy for Citrix offices."
"Sometimes when I enable NetScaler, it makes the box crash randomly."
"Technical support sometimes takes a little longer because of the multilevel ticket priority."
"A big requirement for us is to be able to scale for multi-tenancy, and this solution doesn't really provide for that."
"The solution's pricing is a big concern and should be improved."
"It is true that it is a bit pricey compared to newer technologies coming to the market. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars."
"I feel that Citrix NetScaler's customer support needs to improve."
"They need to make the solution a little more familiar with easy study guides, learning videos, etc."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"It's not for startups or SOHO."
"Our licensing fees including technical support are approximately $3,500 USD."
"In Turkey, everything is good, but it seems expensive for us due to the currency exchange. I don't have a specific rating scale, but if I had to rate the price, I would say it's around a six out of ten."
"Costly product and complicated licensing."
"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
"Price-wise, I feel that the solution is a little bit expensive."
"NetScaler does the same thing as an F5 and it's cheaper."
"We have all the features and functions of Citrix because we have a premium license."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
