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.

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

"Ease of use in deploying and having it up and running requires minimal knowledge."

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

"It helps with defining server load balancing tasks and managing SSL certificates, ensuring the communication flow through the Fortinet gateway."

"The GSLB, the DR side, is the best part. Because we had our main side in one city, we created another, and we had a complete MPLS over the internet. We used the GSLB and data loss for our business applications."

"This ensures that clients can connect to their applications without interruption."

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

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

"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."

More Fortinet FortiADC pros

"The most valuable features are for the ADMs and the overall monitoring environment."

"Unified Gateway allows me to provide secure external access to applications for suppliers and customers while requiring Multi-Factor Authentication."

"This solution allows the user to easily scale out application delivery, and provides secure remote access."

"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."

"Its flexibility, agility, and robustness are the most valuable. Its management and implementation are also quite easy."

"From a security standpoint, It is a comprehensive solution in a single box."

"The web application firewall which protects our services on the internet, and then of course services like our ability to provide high availability for the services we are offering are the most valuable features."

"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."

More NetScaler pros

Cons

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

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

"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."

"The solution needs to integrate sFlow. sFlow provides better visualization of the bandwidth and types of traffic passing through the device. When used in the traffic path, this information can be really useful."

"The solution’s pricing could be improved."

"Because it is so generic, the documentation requires special attention. A person who has not worked on Fortinet FortiADC or a similar product will struggle to understand what the document is trying to say. The documentation could be more specific, and more detailed."

"The configuration is relatively complex."

"The product’s price could be reduced. Also, some of its features need to be more advanced."

More Fortinet FortiADC cons

"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."

"The reporting is not so good. They don't have an application to connect the logs."

"I would like to see the virtual and desktop license included in the pricing."

"It does not have a sandbox cloud service and antivirus. It should have on-prem or cloud sandboxing and antivirus."

"Citrix should improve the documentation. It is not really clear how to set up many features to our advantage. When we setup Citrix NetScaler ADC, we have to figure it out by ourselves without a lot of documentation."

"Citrix should offer a demo or free-trial version of NetScaler. Several other vendors do, but Citrix does not. Pricing should also be more readily available."

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

"Mastering it requires significant learning and training due to its complexity."

More NetScaler cons

Pricing and Cost Advice

"The solution could be more cost-effective."

"Compared to F5, FortiADC pricing is better."

"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."

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

"The price is competitive"

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

"They offer a perpetual license."

"The product has affordable pricing."

More Fortinet FortiADC pricing and cost advice

"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."

"The tool is cheap."

"There isn't much of a difference between the cost of Citrix and that of other similar solutions."

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

"We get value for money. Its price is fair. I don't think it is overpriced."

"The license for Citrix NetScaler is on an annual basis and it is reasonably priced."

"The solution is undoubtedly very good, but it is expensive."
