Executive SummaryUpdated on Jan 1, 2025

NetScaler and Azure Web Application Firewall both compete in the web application security category. Azure Web Application Firewall has an edge due to its integration with the Azure ecosystem, making it ideal for cloud-centric deployments and easier configuration.

Features: NetScaler provides flexible deployment options with features like SSL offloading, traffic management, and application delivery suited for complex setups. It incorporates TriScale architecture, which supports scalability and consolidation. In comparison, Azure Web Application Firewall integrates seamlessly with Azure services, offers DDoS protection, and leverages OWASP rules for effective request filtering.

Room for Improvement: NetScaler requires improvements in asymmetric optimization, better support for custom scripting, and enhanced troubleshooting documentation. Its graphical user interface could also be simpler and its pricing model more flexible for smaller deployments. Azure Web Application Firewall could benefit from better documentation, real-time monitoring features, and simplified licensing to support smaller enterprises.

Ease of Deployment and Customer Service: NetScaler offers deployment options for both cloud and on-premises environments, but users often need expert help to leverage its full capabilities. Its technical support, despite improvements, can be inconsistent. Azure Web Application Firewall provides straightforward integration within Azure, supported by a robust support network, though ticket resolution speed may be inconsistent.

Pricing and ROI: NetScaler's pricing is seen as high with a complex licensing structure, which might not be economical for small businesses, but its comprehensive features are valued by users. Azure Web Application Firewall provides competitive pricing within the Microsoft ecosystem, offering clear cost management and scalability that appeals to a wide range of organizations.

It's easy to set up because you point the DNS to it, and it's working in under 15 minutes

Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Comprehensive suite simplifies configuration while frequent updates require management

Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.

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

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"The UI is good."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

"The solution offers the flexibility to control configuration rules."

"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

"It is a fast and secure DNS."

More Cloudflare pros

"The integration it has with GitHub is great."

"It's a good option if you want a solution that's ready to go and easy for your team to learn. It's cloud-based, so you don't need to buy or maintain any hardware infrastructure."

"Azure WAF is extremely stable."

"The most valuable feature is that it allows us to publish our applications behind the firewall."

"The solution has good dashboards."

"It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure."

"We have found the most valuable features to be the web application, minimal skills required for management, control through policies, and automation."

"The return on investment is good."

More Azure Web Application Firewall pros

"The advantage of Citrix Web App and API Protection is just its graphic user interface for beginners. The solution is nothing special, but we have to use it for the corporation. Another advantage of Citrix Web App and API Protection is that we have our copy to test things and get the know-how of it."

"The NetScaler appliance has provided a lot of customers with greater high availability for their enterprise applications within a single site and across multiple locations."

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

"The flexibility in configuration options is impressive."

"The solution can scale."

"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."

"The analytics are a great feature."

"The program is easy to install and to set up."

More NetScaler pros

Cons

"Cloudflare's console should be made more user-friendly."

"The solution could work at being less expensive. It costs a lot to use it."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"The documentation could improve for Cloudflare DNS."

"The solution could be more user-friendly."

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"Cloudflare should add more documentation and pricing to the cloud version."

"DNS Management."

More Cloudflare cons

"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."

"The documentation needs to be improved."

"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."

"The support for proxy forwarding could improve."

"Azure WAF should not be deployed in the middle of the traffic."

"From my point of view, there is no need for improvement."

"Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup. The basic setup does not allow me to use the web application firewall and other additional services."

"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."

More Azure Web Application Firewall cons

"The licensing model and technical support of the solution could be improved."

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

"We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers."

"The interface needs to be improved because the competition is coming up with ones that are more eye-catching, straightforward, and sophisticated."

"It was challenging explaining to customers that it's no longer NetScaler but ADC, and now it's not just ADC but also the rebranding from NetScaler."

"Overall the price of Citrix ADC could be more competitive."

"Deployment is complicated."

"Getting to use some of the advanced tools, even with the assistance of Citrix support, can be challenging."

More NetScaler cons

Pricing and Cost Advice

"The product's pricing is cheap."

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"The product's pricing is minimal compared to other products."

"There are no additional costs beyond the standard licensing fees."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

More Cloudflare pricing and cost advice

"The price is for this solution is fair and there is a license needed."

"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."

"The price is reasonable. It is approximately $2,000 US per month."

"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."

"I give the pricing a nine out of ten."

"We have an enterprise agreement with Microsoft and the pricing is good."

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

"It is an enterprise solution. Thus, its costs are reasonable."

"Costly product and complicated licensing."

"The solution's pricing is very high compared to its competitors."

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

"You can do CapEx and then a yearly monthly fee, or you can do a subscription model, whether that's one month, month-to-month, or three-year subscription model."

"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
