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

Pros
For the past two and a half years, we have not had a need to open a tech support ticket. It is really stable. In the past, our experience with tech support was that they were extremely helpful.The Deterministic CGNAT feature is valuable for us.

It is the best product out there.It has an easy user experience and user interface. The security is effective and better than its competitors.This product protects us from Internet attacks using its firewall features to block any attacks.Scalability is great. One of the best features of NetScaler is that it can scale out.This solution allows the user to easily scale out application delivery, and provides secure remote access.One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low.I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production.Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature.

Cons
The setup depends on certain situations. In certain scenarios, it may be more complex than others. For example, while the initial configuration may be easy, the environment itself may be complex and that may limit the ease of deployment. It is easy for those who understand their environment.It scaled well for our numbers, up to 3 million subscribers for our most crowded region but I would like to see the same scalability numbers for the virtualized version as well.

It can be difficult to setup.We would like to see more monitoring features going forward, because the current product monitoring options are not enough for security usage.I would like to see more integration for single sign-on.Should offer more flexible cost-effective licensing for small to medium sized organizations.The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified.In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it.Development team's response time could be better.Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used.

I do not have any experience with the pricing of the product.We are quite happy with price. It's not too high.The licencing model that we bought has been good. The licencing model is more flexible.We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.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.It all depends on the features that will be used and the number of accesses.Costly product and complicated licensing.It's not for startups or SOHO.
