Executive SummaryUpdated on Dec 17, 2024

NetScaler and Fortinet FortiADC both compete in the application delivery controllers (ADC) market. NetScaler seems to have the upper hand with its advanced features and integration capabilities, while FortiADC is notable for its cost-effectiveness.

Features: NetScaler offers flexible deployment models, the pay-as-you-grow Triscale architecture, and high compatibility with Citrix solutions. It provides robust security features, including a strong SSL VPN. FortiADC is recognized for its cost-effectiveness, straightforward load balancing, and integrated global DNS operations.

Room for Improvement: Users of NetScaler suggest enhancements in asymmetric web content optimization and scripting capabilities, reporting inconsistencies and bugs in updates. FortiADC users express a need for better support and documentation, a simpler setup process, and more robust security features similar to FortiWeb.

Ease of Deployment and Customer Service: NetScaler provides flexibility in deployment across on-premises, cloud, and hybrid environments, with adequate yet variable technical support. FortiADC is primarily used in on-premises and private cloud setups. Its support is satisfactory, though there's a demand for more technically proficient support personnel.

Pricing and ROI: NetScaler is priced as a premium product with high licensing fees but is deemed favorable in ROI due to its features and reliability. FortiADC is competitively priced with straightforward licensing, appealing to smaller enterprises but offering fewer features.

IT Manager at Technology Evaluation Center

High-level load balancing and routing protocols but scalability is limited to 200 gigabits

The initial setup and configuration are very easy because the solution includes a simple OS. Initial configuration takes about ten minutes for simple environments. It is important to assess the environment and decide what services, servers, and web applications are needed. The solution can be configured in router mode or one-arm mode which uses source NAT as destination NAT to send traffic to the firewall. One-arm mode is more complex and requires discussions with our engineers. For example, you have a website with Node.js for your programming language, Amazon S3 for your CDN, NGINX for your web server, and you use both React and reCAPTCHA. Our team meets with your developer to learn your website and OS through a multi-step process and then we configure the solution to protect everything.

A tool for centralized management including inventory and sales tracking

Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"The most valuable feature is its simplicity."

"I am impressed with the product's load-balancing feature."

"It's a good product because it supports all the features that ADC solutions in the market can support, like F5 solutions, for example, such as the LTM of F5."

"The user interface is very easy and integrates with Sandbox easily."

"I like the solution's load balance with DNS intelligence."

"The solution provides high-level services such as availability, redundancy, and load balancing between servers."

"FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms."

"From a technical perspective, it is the most scalable device from Fortinet."

More Fortinet FortiADC pros

"We have good customer support."

"My clients use it for load balancing."

"Citrix Web App API Protection allows you to enable a blocking mode"

"NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections)."

"Content filtering, security layer, and application customization features are the most valuable."

"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."

"The maintenance of the solution is not complex."

"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."

More NetScaler pros

Cons

"I think it would be helpful if Fortinet put more video examples on their cookbook site."

"The L7 Persistent load-balancing algorithm has not worked for me after having tested it many times with my customer's in-house application. I'd like to suggest that the company make sure that all load-balancing algorithms work properly with most applications, even those that are in-house apps."

"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."

"If I need design help, they do not assist; they say it is a design issue they cannot support, and I must approach the system integrator."

"It would be good if they built in a fully functional web application firewall."

"Fortinet FortiADC should include an advanced-level SD-WAN."

"The product's stability for VMs could be better."

"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."

More Fortinet FortiADC cons

"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."

"They can improve the scalability and the multi-tenancy feature. We recently tried to configure an authentication, and we ran into some issues while using the web-based GUI. It was very slow when you log in with your credentials in the web-based GUI. Each time we clicked on the menu, it tried to do the authentication. It works properly in the console."

"The GUI should be improved."

"Maybe creating policies with simple regular expressions."

"The configuration is complex, and only one or two people know how to assist when problems arise."

"The setup was not simple."

"Citrix ADC is a complex product, and it takes time to understand these things. But the documentation is poor, and the deployment is difficult. Integration could also be better because what I find is that you cannot easily integrate the panel in the second sector. What I have found is that in the last index, there is a limitation when getting validated. Technical support could also be better."

"The configuration for its web application firewall is complicated."

More NetScaler cons

Pricing and Cost Advice

"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."

"The solution's pricing is an issue and should be improved."

"I believe the price is good. It's fair. There are no extra costs."

"They offer a perpetual license."

"The product has average pricing. I rate its pricing a five out of ten."

"The price is competitive"

"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."

"Compared to F5, FortiADC pricing is better."

More Fortinet FortiADC pricing and cost advice

"The licensing costs for this solution vary depending on which model is being used."

"I rate the pricing an eight out of ten since it is expensive."

"The licenses for this product are payable as a yearly subscription, and carry a high price-point. The subscription scheme is quite complicated, and costs will increase with each additional feature that is required, outside of the basic setup."

"Ninety day free trial makes it easy to try out this solution."

"You get the value for your money. There aren't any hidden fees."

"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"

"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."

"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
