Quotes From Members Comparing Citrix NetScaler ADC vs F5 BIG-IP

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
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.Provides resiliency for applications that reside on servers, as well as connectivity to remote applications.

The occasion in which we needed technical support, we didn't have problems with them, because they always answered our questions without any trouble.I have Big-IP change and control manager, which give me the roll back option. Therefore, I can view the last things which happened on the device.It is very intuitive, easy to deploy, and manage.Users can see a remarkable performance difference from a qualitative sense.Our experience has been very good, in terms of performance, and securing our application infrastructure.The Local Traffic Manager (LTM) provides a simple low balance and SSL decryption, in addition to some TCP parameters, for incoming and outgoing traffic to redirect appropriate traffic patterns to appropriate servers.We are using Application Security Manager (ASM) as a web application firewall, where there is a security signature to avoid a web level breach.It helps us recognize sessions from certain IPs that are authorized to manage the application. This is a function we haven't found anywhere else.

Cons
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.Getting to use some of the advanced tools, even with the assistance of Citrix support, can be challenging.

They need to improve the interface and some of the functionalities.We need best-practice information. They have something called DevCentral and a blog. But we want something from F5 itself regarding how to tackle the false-positive configurations. If you go into detail with so many configurations it will find so many false positives from the moment it is enabled that it will quickly impact your applications, and it will not work.I would like there to be more device security. I would like the tool to support SSL links, along with SSL and TLS.They need to develop the reporting tools further.Implementing whitepapers with a lot more applications could easily be added.There is a challenge in Pakistan. This is when there is a hardware failure. Sometimes, it takes more time to get a replacement because it is sent out from the U.S. or some other regional outpost. Thus, it takes two to three days to receive a replacement.I would like to see F-5 implement a regular routing like in other Linux-based devices. When we try and integrate in some complex networks, we have to use some additional routing scenarios from a Layer 3 perspective, then we have some problems. It would be great if this were fixed somehow.Logging is a bit of a problem. Logging and monitoring are only in plain text. You have to search and you have to know what you are searching for to find anything. So of course, monitoring and getting alerts for abnormal situations is hard. There are no tools for monitoring and alerts

Pricing and Cost Advice
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.

The pricing is inclusive of many features.Security should be involved in any base license. When you bring on F5, you only have default license. Then, the ASM product license has to be purchased. It would be great if F5 could include the ASM in the base license.It's fair, it's not too expensive. Maybe just a little high.It is the best solution, but that comes with an increased price.Try to negotiate all the software features that you require upfront.The licensing strategy for F5 is good.It's not a cheap product, but there are no other replacements for what we do with it.I would recommend that the cost be lowered.
