We use ADC for load balancing, monitoring, security, application firewall, and gateway within my organization. The ADC is a Swiss Army knife of networking and a terrific tool to use for load balancing and secure web servers and services. This tool has a very clean interface and excellent CLI functionality for more experienced users.
  • Load balancing.
  • Gateway Traffic.
  • Application Security.
  • Networking Segregation.
  • Authentication workflows.
Citrix ADC is perfectly well suited for organizations that are looking to perform load balancing, web server security hardening, exposing servers and services through a DMZ in a secure manner, providing access to Citrix/Horizon/VDI environments, and allowing secure access into corporate networks in a selective manner without the need for a full-scale VPN which has a lot of added risks.

Citrix ADC product line offers a wide array of functions and features for securing user access to our environment. We like how this product can be used for many uses (load balancing, content switching, gateway access, posture validation, etc). Delivers a better user experience.
  • Load balancing and Content switching
  • Boost employee productivity
  • Protect applications and APIs
  • Slow support
  • Convoluted API system
  • Dashboard Can be enhanced to simplify viewing
The primary use case is the hosting and delivering of mission-critical web applications where multiple users need access both internally and externally. we use Citrix ADC for SSL offloads and security, secure remote access, loads balancing, and application firewall, web application firewall. We have deployed ADCs on the cloud or on-premises. Citrix ADC is less appropriate for companies that do not have any critical web applications.

We are leveraging Citrix ADC (NetScaler) for several different use cases. We originally bought it to replace Citrix's old Secure Gateway software to proxy user sessions into our many Citrix Virtual Apps and Desktops environments. This is the Gateway feature. We are also using it for load-balancing services. This is for both Citrix products but also other products like Exchange, Oracle, etc. We are using GSLB features to make these services available across multiple data centers.
  • Citrix Gateway
  • Load balancing
  • Global Server Load Balancing
  • Monitoring via ADM
  • At times it seems like there is a flurry of firmware updates needed to remediate security vulnerabilities which creates some overhead.
  • Out of the box automation using ADM is a bit lacking
  • Nit picking but occasionally there are minor config changes that need to be done via CLI or GUI but nothing significant.
Citrix ADC is well suited for a wide range of use cases. It offers very flexible options for load balancing within and across data centers. I haven't personally used every feature. I have looked into Application Firewall features which appear to be very powerful but with that comes some overhead in tuning to ensure you don't end up causing impacts to your products with a bunch of false positives.

We are an SMB so we use the Netscaler VPX version of Citrix ADC. It acts as our main firewall for application delivery operations. We host a Citrix Web Interface and application farm behind it. Having users frequently in low bandwidth situations, our Citrix ADC implementation allows us to host the apps in our data center while requiring just scene shots and mouse/keyboard clicks from the user's side. We have been running it for 6+ and have had no security issues in that time frame. It allows us to avoid the complexity of a VPN in running all data through the Netscaler.
  • The GUI interface is fairly easy to learn making ramp-up time faster than some similar products.
  • It is used by thousands of companies around the globe so finding free support on Google is usually quite easy.
  • The virtual implementation version of the product runs on a Linux-based hypervisor install so no additional licensing is needed for the OS.
  • When used in conjunction with a Citrix Web front/Storefront, the integration is very tight making the passing of packets very quick.
  • Even in the lesser VPX versions, there is the ability to have a cluster of Netscalers to allow for uptime capability.
  • Although the GUI is easy to use, some of the more complex situations require knowledge that is not common among the average IT person.
  • The system makes it very hard to change and update SSL Certs.
  • Some adjustments do require leaving the GUI and going in via Putty/telnet/SSH to use the command line.
  • It mostly works well with other Citrix products.
Citrix/Netscaler ADC is well suited for any shop that plans on publishing VDI-based applications or machines from a Citrix-based environment. The strong integration between the Netscaler and the back-end Citrix infrastructure cannot be beaten when it comes to having a 99% uptime-type solution. Having a Netscaler allows shops to publish apps via the standard internet without the need of worrying about VPN or other security measures You can add a VPN on top but the basis of the Netscaler is to allow the publishing in a clientless environment outside the Citrix client itself. if your back-end VDI infrastructure is not mostly Citrix-based, the Netscaler may work for you but it will be a bit more touch and go as to compatibility and uptime.

We use it for virtual desktops and provide it as a service to other organisations. It allows us to manage the desktops remotely and securely instead of going down to the individual offices to manage so can save us some time.
  • Virtualization
  • Publishing VDI image to users
  • Hard to manage with too many different organisations to cater for
  • Hard to customise for single users
It is more suitable for virtual desktops in the company. We provide virtual desktops for many different organisations and it gets harder to configure when all of them login through the same portal. Some of them require customisations but we try to maintain as standard image so we are not able to customise for them

We currently use Citrix ADC primarily as a reverse proxy and a load balancer for our web servers. We also use content switching feature to send web traffic to correct back-end resources. In the future we will be setting up GSLB (Global Server Load Balancing) to better route web traffic between our 2 sites. We also use Citrix Gateway to be a front end for our Citrix Virtual Apps and Desktops.
  • Load-balancing is very effective.
  • Makes a great reverse proxy to ensure back-end resources are secured.
  • Very flexible in sense that almost any rule can be configured.
  • Works very well with Citrix Virtual Apps and Desktops (XenApp & XenDesktop).
  • The policy engine syntax is a bit complicated to learn.
  • The UI is good but navigation is a bit cumbersome.
  • Configurations are somewhat complex for some features.
If you have Citrix VDI deployment Citrix ADC is a must to be able to login remotely. Citrix Gateway works really well in that sense. It also works great for load-balancing and content switching. Its policy engine allows for almost any configuration and it can deal with any kind of traffic based on these policies and configurations.

Citrix ADCs are used by our organization as load balanced gateway for application and desktop delivery for both local and global points of presence; the ADCs allow us to ensure a consistent user experience across multiple application and desktop delivery solutions as well as helping increase the security of our WAN edge solutions.
  • Helps protect our Citrix app/desktop delivery solutions via shared code base
  • Helps protect our WAN edge solutions via consistent gateway access to edge solutions via consistent gateways
  • Helps ensure user experience via load balancing
  • WebUI could use some updating and be made more intuitive.
From our experience with Citrix ADC, the product is a well-suited solution for application-level quality of service and quality of user experience, denial of service protection, global server load balancing, and high availability multi-node load balancing solutions, web application firewall. The product can also be utilized for SSL offloading but our organization uses a different solution for that so I can not speak to ADC usability for SSL offloading.

We used to use Citrix in a limited fashion on an ad-hoc basis. Recently we have decided to implement this as a solution for the entire company. I'm sure there are other employees that use this for many more reasons but the primary reason is for secure remote access which simply works.
Having this implemented solves a massive parking issue at my company, with +1500 employees this has become an issue with most people parking at nearby malls which is off-premises, which is never the best idea. Due to a fair program introduced and by using Citrix to remote into our work PCs this has been a definite solution. It also assists those with special needs, or just individuals who are unable to come into the office for a prolonged period of time by allowing them to continue with work as normal.
  • Secure remote access.
  • Relatively speedy connections.
  • Older versions used to be quite laggy but this has really improved to be quite 1 to 1.
  • Remote PC use could be even faster.
  • Unable to receive audio when remoting.
  • Log-in process contains maybe 1 or 2 too many steps.
Citrix from a remote access perspective is well suited for a situation where employees need to access computers while not being physically at the vicinity of employment. There are a number of factors that can prevent someone from not being able to be at work physically and Citrix aims to solve this by enabling a secure SSL 2-step authentication process which connects to a specific PC of one's choice.
I myself am physically disabled and this application alone has enabled me to continue working on days when I'm not feeling well (which is often). It allows me to still be a part of the team without feeling disconnected from everyone.

There's not much to say on the negative side other than working remotely is still not the same as physically being there and interacting with people on a person-to-person level, but for what it does, it's perfectly acceptable.

The company is using Citrix ADC (Netscaler) to deliver applications from our cloud services throughout the whole organization, which is all over the world. We have appreciated the speed and flexibility in accessing the applications we need, particularly when out of the office. We use our Citrix environment from anywhere because of this awesome technology.
  • Secure connection while using the application
  • Citrix can be accessed from anywhere in the world from any device and any operating system.
  • Sometimes, we face occasional speed issues. No big deal.
  • Configuration is hard to do at the beggining.
The company has been using Citrix ADC (Netscaler) for a few years now. The features are user-friendly, and what I most like is to be able to log on to my work files and apps at home or when I am out of office on business travels. We use Citrix throughout all sites of the company all over the world. Depending on the connection you are logged into the software can be slow. There are also often outages and random logouts.

Citrix NetScaler was purchased for our department to serve as the primary load balancer for all of our web applications. Whether it was MS Exchange or an important web server to host for our staff or customers, this has been a product that is necessary to complete our objectives. Not only does Citrix have great load-balancing capabilities but they also offer a solid Web Application Firewall as well. This has helped us add another layer of additional security to our environment to block the top 10 OWASP threats. If you're looking for a product to accomplish this, look no further.
  • Support is fantastic!
  • The software upgrades are simple.
  • Installing the hardware and setting up the load-balancing is not too complicated due to the wealth of documentation they have.
  • Rule building is complex.
Citrix ADC is a must for enterprise applications such as Microsoft Exchange, Share Point, or another critical website that need to be load balanced across the network. It may not be suitable for a small business who just needs to host there own website or may not have the need for high availability.

I work as a consultant specialized in virtualization and its supporting technologies. In our scope for our client (a division of a larger enterprise) we manage a secured Netscaler deployment that ensures our Citrix Environment is (pardon the redundancy) first and foremost secure. From an analytical standpoint, we leverage the features Netscaler provides like single sign-on to storefront and the ability to monitor other key infrastructure components like our XML Brokers and Storefront itself. In our deployment, our Netscalers are load balanced, built for high-availability for a demanding customer base.
  • Secures connection to XenApp and XenDesktop (SSL)
  • Easy central management for XenApp and XenDesktop (SmartControl)
  • MFA Support.
  • Initial configuration can be time-consuming, one misconfigured item can require a reset and restart.
  • Firmware upgrades. Have a back up handy even though the process has improved over time its always a good idea to have the latest backup on hand just in case, this has saved me a few times.
  • User stability. like with all product peak hours can degrade performance significantly sometimes leaving sessions hung which require manual intermission. These cases are minimal, not a daily occurrence.
Netscaler isn't for everyone BUT if you are deep into Citrix and rely on it as a mission-critical platform, then Netscaler can be a breath of fresh air to the sometimes slow or laggy Citrix experience (when its not peak hours, aka 8:00 am when everyone logging in) outside of that hectic time Netscaler is a great way to go. The insight you get from it and its integration with other Citrix products is well worth the cost.

We use Citrix across the organization. It is used for field offices to access client server applications. It is used for remote email and accessing networks files.
  • Users have their own user profile logging in.
  • Access to network printers remotely.
  • Access to network file that would otherwise be unavailable.
  • Shutting down the receiver when closing out of Citrix.
  • Compatibility with receiver versions across vendors using different versions of Citrix.
  • Occasional speed issues.
Works well for remote offices with company held machines but less appropriate for access with public PC as the client needs to be installed.

We are using Citrix NetScaler to provide a Citrix environment to deploy apps to users. We can also deploy a desktop and remote access to our users. This app is a mission critical app and Citrix provides fault tolerance. If one app server goes down we have several others to take over.
  • Load Balancing
  • Fault Tolerance
  • Centralized Administration. It's a lot faster to setup a Citrix account than a whole user. You can deploy that same app across platforms as the Citrix client works on both iOS and Windows.
  • Citrix handles video much better than Microsoft Remote Desktop Services.
  • Cost. Citrix costs more and you still need to have Microsoft Remote Desktop below it. However the value is there. Citrix does a better job.
  • Client needs to be reconfigured periodically. Keep your config file handy so you can just import it back in.
  • Little harder to troubleshoot issues. It's no longer a single server that could be the problem.
Citrix is well suited for small IT shops where you need to reclaim time. Your time for user administration goes down. Citrix is very stable. Once you have it working you can usually set it and forget it. If you need failover Citrix handles it great. Just add more App Servers.

We use the NetScaler to deliver published applications from our cloud services to our clients. Our own support team uses it to deliver our services, and we provide the platform to our clients. We, as well as our clients, have appreciated the speed and flexibility in accessing the applications we need particularly when in a mobile/out-of-office setting. It has helped our distributed workforce's efforts.
  • Provides flexibility in configuration of app delivery.
  • Provides speed in the app delivery.
  • The full desktop environment through the Xen environment is configurable.
  • There is a lot to configure and know when setting up the first time.
  • Tweaking and fine-tuning during set-up can be time-consuming.
  • Complex Issues with configuration often require Citrix support engagement.
We have applications that are client-server based but we require access to them outside of our offices. The cumbersome VPN process has been overcome by delivered apps through the Citrix Receiver. It's very useful and practical; all you need now is a fast and reliable Internet connection. If that kind of flexibility is not required or other technology in place where access is given, then this may not be the best fit.

Citrix NetScaler is a big player for us. Without it, we would not function. We use it across our whole organization (manufacturing, shipping, sales, etc.) which is international including the Netherlands, China, and the US. We utilize our Citrix environment from anywhere because of this awesome technology. Citrix NetScaler is definitely worth its ROI.
  • Secure connections for all users.
  • Delivers applications fast.
  • Not overly expensive.
  • Solid customer service.
  • Web GUI
  • Options more visible
  • More customization
I think it is well suited for a multitude of different environments/settings/industries. It can deliver on for small, medium or large size companies. If you have a non-existent, small or large IT department in your company, Citrix will work well with all of them and all those environments.

We provide global site load balancing with high availability pairs for redundancy in three data centers across the globe for our Citrix published applications as well as our virtual desktops to over then thousand users internal and external to our network. Citrix Netscaler helps achieve this as well as SSL VPN access and reverse proxy for secure access to some of our web applications and sites.
  • Provide secure and easy access to Citrix XenApp applications and XenDesktop VDIs to end users with customizable front-end.
  • Access can be from anywhere in the world from any device and any operating system.
  • Users with low bandwidth and high latency may still access our applications and virtual desktops securely with reasonably fast experience.
  • SSL VPN difficult to implement as well as manage with lack of fully functional tool to manage users for administrators.
  • Citrix Receiver to access Netscaler can be cumbersome to deploy and version stability and bugs need improvement.
  • Netscaler firmware updates can be difficult to upgrade with some native features not functioning correctly after an update.
Citrix Netscaler can be a powerful network appliance for environments that are fully committed and open to utilizing a network appliance that isn't made by a traditional network vendor. Administrator user experience has improved over the years and will continue to improve with the flexibility of virtual and physical appliances available for medium and large enterprises.

Used mostly in our accounting department, but other employees have used it as well so we can publish applications such as DST, Argus, shared drives, etc.
  • It is good for publishing apps instead of having to install on each computer.
  • Works pretty well with very little technical issues.
  • Easy for employees to understand and use with very few questions.
  • Sometimes causes issues with apps and compatibility depending on the software.
  • Sessions sometimes stay open and need to be cleared out by an admin.
  • Sometimes slow to open apps when connecting.
Well suited for applications such as Great Plains and Management reporter, a very intense software that you would not want to install on every machine locally. Less appropriate for small software packages or licensing such as Adobe Acrobat, etc.

We use a pair of Citrix NetScaler SDXs to deploy virtual NetScaler VPXs to function as a front end (NetScaler Gateway) and as a separation of DMZ and internal network appliances for specific application load balancing concerns. The internal VPX instances load balance printing, email, web, SQL, and other mission-critical concerns. The DMZ VPX instances load balance public web concerns.
  • The NetScaler is a great ADC for load balancing multiple different sets of concerns. Being able to run the virtual appliances in hypervisor from the appliance is an amazing design choice.
  • Being able to effectively run a VPX load balanced pair nested inside and SDX is an infrastructure masterpiece.
  • Ease of setup is a great feature for the NetScaler. Those that are not strong on a command line will be able to setup the SDX, MDX, VPX with little knowledge of the commandline.
  • Some of the menus for the NetScaler Gateway could use more detailed knowledge base articles detailing what each 'switch' does.
  • The refresh rate on the web(GUI) are too slow.
  • Get rid of Java completely, more modular updates to the codebase, e.g. quicker updates to fix critical issues.
The Citrix SDX and MDX models are well suited for large scale deployments with multiple load balancing needs and concurrent Citrix XenApp/XenDesktop environment. Being able to deploy the NetScaler Gateway and load balance multiple pools of specific app loads are the strengths of this platform. The SDX and MDX models would be overkill for a strict XenApp/XenDesktop deployment unless it had a huge concurrent session load with a high throughput need. The VPX model is designed for smaller XenApp/XenDesktop farms and smaller scale load balancing needs.

Citrix NetScaler is being used across the organization, providing load balancing and increased availability of applications and services. Wherever a business critical service exists it becomes paramount to provide end users with the highest available levels of service and reliability. Load-balancing services (such as those provided by Citrix NetScaler) provide this type of reliability and trust.
  • Flexibility. NetScaler assumes its admins know a bit about networking and in-depth details surrounding the applications they are configuring access for/to. This being so, the range of configuration options is very broad allowing various versions' combinations of protocol patterns, expressions, rules etc., all to the benefit of the admin.
  • Granularity. Having such a broad range of configuration options available, while still allowing simple options to be configured simply. The GUI is well-stylized and navigation has a good flow.
  • Ease of control. For load-balancing of simple services right out of the box, NetScaler makes it pretty easy, compared to the range of options available in the surrounding GUI and under the hood.
  • The companion product that is the Command Center, feels like an afterthought/step child. Though recent versions have been better, some of the trigger rules have issues applying (at least with the tests in my environment to VPX & MPX appliances) and there's an overall unease in trust with it.
  • Like most products in this type the CLI will provide the best experience where the GUI fails. An example is stats. A vserver that uses service groups will not show individual stats per server in the GUI (as of v10.5) but will in the CLI. I think things like this are just version deficiencies and will be corrected in future releases.
  • Java applets.
  • Citrix documentation is getting better but hasn't been the greatest in recent years and sometimes tends to be conflicting.
Citrix NetScaler is suited to any environment where hardware load-balancing, application delivery or SSL offloading is a requirement. It's a product that can be used to manipulate traffic flows in a multitude of different ways and its only limit is the protocol, application and imagination of the administrator. It's not a product that includes helpful wizards to guide the admin through each process gracefully. While it is a fairly intuitive product to use, it's not for someone who is not initiated into the ways of networking and network protocols and communication. Nor is this a product that would lend itself solely for the usage of single usage scenarios where small traffic flows would be expected (although if desired the VPX product would probably suffice in that specific scenario depending on the environment).

Citrix NetScaler is being used for multiple purposes; two-factor access gateway, HTTP redirects and rewrites, web application firewall, and load balancing. The NetScaler provides the ability to perform all these functions and still leave room for growth and more features in the future. The access gateway, allows health records to be secured with a two-factor login process and also addresses data loss prevention. The load balancing addresses updates and patches that our server administrators frequently do. This allows them to update or patch one server at a time, without a production downtime.
  • Load Balancing - The ability to monitor servers with almost any method you can think of, makes it a really nice utility.
  • HTTP Redirect/Rewrite - This allows URLs to be protected and rewritten. In the healthcare industry, privacy is very important.
  • Access Gateway - Data loss prevention is a must when it comes to health records. The gateway can be customized and set up with two-factor login, allowing the additional line of security upon authentication.
  • The documentation could use an overhaul with specific examples related to the command line as well as GUI. Explanations in the documentation would also be helpful.
  • Being able to have more than just one routing table would allow the ability to leverage security.
I found the Citrix NetScaler to be a great tool with more features than we were able to get to in the healthcare industry. The reporting was also great and increased the resolution time on troubleshooting any issues.
