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

"Customer service is excellent."

"The main feature that we use is GSLB (Global Server Load Balancing). GSLB makes the customer's network more reliable by scaling applications across multiple datacenters. GSLB as a disaster recovery solution can direct traffic based on site availability."

"I use load balancing technology like Round Robin or low weight to maintain session-based connections. This ensures that clients can connect to their applications without interruption."

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

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

"Content caching and content compression are good features."

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

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

More Fortinet FortiADC pros

"Citrix is good for application protection."

"We use the solution's IP Reputation and bot protection features."

"The most valuable features of Citrix ADC are load balancing and application firewall."

"I would say the rewriting and redirection functions are must-have's for us."

"We appreciate that this solution facilitates our access to Citrix internet."

"The solution can be configured very granularly and has good control over security."

"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."

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

More NetScaler pros

Cons

"The initial setup could be simplified."

"Though FortiADC is useful, I'd appreciate more user-friendly features and in-depth insights into network activity, like detailed logs and AI-driven feedback for optimization."

"The solution’s pricing could be improved."

"I had a terrible experience with Fortinet support. I only used support once when I bought the solution. I got no response for two days. However, I believe that it's no longer the case. Fortinet solutions have problems when they're launched. For example, we had issues with Fortinet's authenticator when it came out. We also had trouble with FortiNAC in the beginning."

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

"The configuration is relatively complex."

"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."

"Setup could be easier. The company's homework is to redesign those menus to configure with the smallest number of steps."

More Fortinet FortiADC cons

"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."

"We would like the licensing model for this product to be improved, as it isn't currently very transparent. There isn't a standard package available, and each extra feature creates an additional cost."

"The SLB could be better, and they should improve it."

"The setup was not simple."

"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."

"This is an expensive solution."

"I would like to see them make it easier to do some of the more complex things. For example, a web re-direct requires two pieces to it. You have two ports and when people want to go to a web page, they just type in the webpage that on the backend it will redirect them to a secure link. The initial setup of that is cumbersome because you have to do it twice. There are things that can be replicated. The IP address, for example, is the same. This change would go a long way. Don't make me do it twice and don't make me have to read tons of documentation to figure out how to do it. Ease of configuration for some of the more complex processes would be a good improvement."

"Citrix NetScaler has been recently acquired by another company and the support has been negatively impacted, the solution is at its end of life. The support for the solution could improve. The sales team needs to be improved."

More NetScaler cons

Pricing and Cost Advice

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

"The solution could be more cost-effective."

"Compared to F5, FortiADC pricing is better."

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

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

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

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

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

More Fortinet FortiADC pricing and cost advice

"Price-wise, I feel that the solution is a little bit 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."

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

"In Turkey, everything is good, but it seems expensive for us due to the currency exchange. I don't have a specific rating scale, but if I had to rate the price, I would say it's around a six out of ten."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight or nine out of ten."

"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."

"The firewall license is included by default, with no additional costs."

"The solution is expensive compared to one of its competitors."
