Executive SummaryUpdated on Jan 1, 2025

Azure Front Door and NetScaler compete in the traffic management and application delivery category. Azure Front Door holds an advantage with its global accessibility and strong customer support, while NetScaler's strength is in its feature-rich performance and robust ROI despite higher costs.

Features: Azure Front Door is known for its global load balancing, integrated CDN, and a powerful web application firewall that enhances security. It ensures seamless traffic management across various geographic locations. NetScaler excels with its flexible deployment model, offering features like SSL offload, load balancing, and application delivery. Its integration with Citrix solutions is particularly valuable for users needing a comprehensive package.

Room for Improvement: Azure Front Door can improve by expanding its integration with various cloud vendors and private applications beyond its current Azure infrastructure focus. NetScaler, on the other hand, should focus on innovation and simplifying configurations. Users have highlighted the need for streamlined updates and reduced reliance on templates to improve user experience.

Ease of Deployment and Customer Service: Azure Front Door excels in ease of deployment, perfectly aligning with cloud-native architectures and offering global accessibility. Its customer service benefits from Microsoft’s structured support, ensuring consistent quality. NetScaler's deployment process is more complex, often suited for on-premises and hybrid settings. Its technical support experiences mixed reviews due to inconsistency in response effectiveness.

Pricing and ROI: Azure Front Door offers competitive pricing through a pay-as-you-go model, aligning with modern budget structures. This flexibility is attractive to users, although transitioning to premium tiers can incur additional costs. NetScaler is often viewed as expensive due to significant initial licensing fees. Despite this, users report a strong ROI derived from its comprehensive feature set, making it a valuable investment for reliable application delivery and security.

Provide bot protection and has proficient documentation

During our discussion with the internal Microsoft team about assessing our environment, they confirmed that we have sufficient security measures, especially regarding edge protection. Internally, we believe we are now certified. In the future, we could consider adding layer four protection from the firewall. Front Door combines CDN and WAF protection, so further enhancing its features could benefit both the customer and us. We monitor the number of users attempting to access our IP or DNS servers. When designing the system, we initially needed to ensure our environment was protected with a WAF. However, WAF is currently too costly for us, so we created private links and connected them to Front Door. Overall, I rate the solution an eight out of ten.

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 solution is good."

"You can assign as many web application firewall policies as you want to the same instance of Front Door."

"It inspects the traffic at the network level before it comes into Azure. We can do SSL offloading, and it can detect abnormalities before the traffic comes into the application. It can be used globally and is easy to set up. It is also quite stable and scalable."

"I find the technical support excellent, and I rate it a ten."

"The most valuable feature is that you can implement resources globally. It does not depend on location and ability or something like that. This is to connect clients around the world."

"Rules Engine is a valuable feature."

"Has a great application firewall and we like the security."

"Azure Front Door provides DDoS protection and features related to WAF."

More Azure Front Door pros

"The most valuable feature is the SSL VPN."

"Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)"

"The most valuable feature for us is the application firewalling in Citrix NetScaler, ensuring only valid traffic enters our environment."

"SSL Offload"

"It is a complete solution for those looking for an all-in-one."

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

"Very stable."

"We use the product for load balancing and as a reverse proxy solution."

More NetScaler pros

Cons

"The product's features are limited compared to Cloudflare. The tool also doesn't work well in a hybrid environment. I would like to see a way to add personalized APIs in the system."

"It lacks sufficient functionality."

"My suggestion for improvement would be to enhance the Data Export feature to include specific tables, particularly the Azure Diagnostics table."

"The product needs to improve its latency."

"There could be improvements regarding its pricing for large-scale projects."

"I dislike the URL set parameters."

"In the tool, there needs to be a good amount of monitoring in the area of health probes to capture in front of what is happening."

"The tool should improve its cost."

More Azure Front Door cons

"Too many bugs in the software and it's always difficult when you need to update."

"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."

"The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support."

"We face challenges with the solution's firmware upgrades frequently."

"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."

"Citrix ADC can be really complex. It isn't very simple like some other appliances that I've worked with. You need a lot of skill and experience to manage it. I'm not talking about a year or two. You need at least four years to understand it very well. It is not that easy to learn. They should make it a lot simpler for users to understand the management of it. They can also provide some additional training. The material they have on the site is not sufficient enough for you to understand how to manage it. Their training is expensive, and not everyone has the funds and experience for it. Citrix isn't very popular around these parts of the world. So, it can use some more marketing, sales, enlightenment, and advertisement. These could bring more market for them. Basically, there are just a few companies that really go for Citrix. Most of the companies go for VMware because they marketed themselves more than Citrix. There isn't much difference between Citrix and VMware. VMware is a little more robust than Citrix. Citrix has focused more on desktops rather than server virtualization, and that's the advantage VMware has over Citrix. Citrix also needs to educate and inform users about the infrastructure that is supported with a version. Currently, if the customers don't look at the datasheet, they might miss this important information."

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

"Their upgrades are not very backward compatible, and sometimes they mess up."

Pricing and Cost Advice

"The product is expensive."

"Considering the standard licensing of the tool, even though we have not checked the billing as of now, it might not be very costly."

"The transition to the premium tier has led to increased costs, making it more expensive than the classic tier."

"It is on a pay-as-you-go basis."

"The solution is a bit expensive."

"The pricing of the solution is good."

"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."

"Our licensing fees including technical support are approximately $3,500 USD."

"It's an expensive product but it works well."

"When compared to other solutions, the cost is high."

"We are quite happy with price. It's not too high."

"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."

"I give the price of the solution a seven out of ten."

"The pricing could be lower."
