Executive SummaryUpdated on Jan 1, 2025

NetScaler and NGINX App Protect compete in application security and performance delivery. NetScaler seems to have the upper hand due to its wide array of features serving large, diverse environments.

Features: NetScaler offers flexible deployment models with features like SSL offload, multitenancy, and strong integration with Citrix applications. Its configuration allows efficient traffic management crucial for large enterprises. NGINX App Protect shines in traffic management and security with its command-line interface and ease of integration, although it may lack advanced features for user guidance.

Room for Improvement: NetScaler needs to enhance ADC functionalities such as asymmetric content optimization and simplify its setup process. Its advanced feature configurations require streamlining. NGINX App Protect should address configuration complexity and improve its user interface, providing better bot protection and pricing adjustments.

Ease of Deployment and Customer Service: NetScaler supports both on-prem and hybrid cloud environments with versatile deployment options. However, its technical support has mixed reviews. NGINX App Protect supports diverse configurations but experiences gaps in customer service responsiveness and expertise.

Pricing and ROI: NetScaler is often critiqued for high costs and complex licensing, although users report significant ROI from its feature set. NGINX App Protect, with potentially lower costs, is considered flexible due to instance-based pricing, yet there's a call for better alignment with enterprise budgets.

Owner at Tech Exchange

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.

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.

Senior security architecture at National Payment Corporation Of India

Offers protection to users from external threats

NGINX App Protect secures our company's application, and it has helped me a lot, considering that we have critical infrastructure in India where we see how lots of attacks come onto our organization's servers. The tool offers protection against multiple threats present in India's IT ecosystem. The tool helps our company to make our payments secure, meaning it has the ability to provide a secure payment environment in India. Speaking about the improvements in our company's application performance since implementing NGINX App Protect, the gRPC support for the solution is very low. My company is not getting any proper documentation on how to deploy gRPC over NGINX App Protect. I recommend the product to those who plan to use it. People can use the product as their company's base server, WAF, or for its proxy manager, depending on the business requirements. My company follows PCI DSS compliance because we operate in a payment-related industry. Right now, my company follows all the standards, so we comply with all the requirements and policies. I rate the tool an eight out of ten.

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 stable, and the DNS servers are simple to use."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"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."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"The overall experience with Cloudflare is positive, with a rating of eight out of ten."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"Generally, I am satisfied with this product."

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

More Cloudflare pros

"The feature that I have found most valuable is its load balancing."

"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."

"The most impressive thing about Citrix ADM is that we don't encounter latency."

"I find all of it to be valuable, because of the flexibility that is built into this product."

"Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."

"We like the periodic upgrades and backups, also made via ADMs, and it makes our environment much more robust and reliable."

"The solution is easy to work with and manage."

"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

"The most valuable feature of NGINX App Protect is its open source."

"I tested specific features and evaluated the solution against the Web Application Firewall. I conducted research to test different detection percentages. I did not use it directly for protection but for evaluation purposes."

"NGINX App Protect is stable."

"It is a stable solution."

"The tool's most valuable feature is the OWASP certification. Additionally, the tool's ability to enforce strong passwords and OTP within minutes is impressive. With its analytics and recommendations, it is a very good solution."

"The tool is not complex and is very user-friendly."

"The initial setup was simple and took three to four days."

"The most valuable feature is that I can establish different services from the firewall."

More NGINX App Protect pros

Cons

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."

"An integrated SSO feature would be useful for Cloudflare DNS."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."

More Cloudflare cons

"In terms of what could be improved, I would say the user interface because sometimes it can be complicated."

"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."

"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."

"I would like to see more integration for single sign-on."

"Technical support could be improved."

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

"There is room for improvement regarding the pricing policy for Citrix offices."

"The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified."

More NetScaler cons

"NGINX App Protect would be improved with integration with Shape and F5 WAF, which would make it easy for users to manage all their web application security with a single solution."

"The dashboard could provide a more comprehensive view of the status of the connections."

"Areas for improvement would be if NGINX could scan for vulnerabilities and learn and update the signatures of DoS attacks."

"The setup of NGINX App Protect is complex. The full process took one week to complete. Additionally, we had to change the network infrastructure platform which took one month."

"They could provide a better user interface."

"The price of NGINX App Protect could improve."

"Currently, the policies have to be handled manually, and you have to create from scratch, which can be a bit time-consuming, in a large environment."

"The product's price is high, making it an area of concern where improvements are required. The tool's licensing model is also not good."

More NGINX App Protect cons

Pricing and Cost Advice

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

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"The price is reasonable."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"I give the price a five out of ten."

"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."

"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."

"We are using the free version."

More Cloudflare pricing and cost advice

"Its licensing cost is much higher than other products, but it is acceptable because it is a one-time investment, and we are getting our requirements fulfilled when we buy this product. So, there is no issue with the pricing."

"It's not for startups or SOHO."

"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."

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

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

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

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

"Its price is comparable to others and affordable."

More NetScaler pricing and cost advice

"The solution's price is reasonable."

"There are no additional fees."

"NGINX App Protect is expensive."

"There is a license needed to use NGINX App Protect."

"NGINX is not expensive."

"The licensing fees for this solution are pretty expensive for what it does, but there is no alternative."

"The product's price is high."

"There are not any additional costs we had to pay to use NGINX App Protect."

Reviews from real users

“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. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“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.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company

Cloudflare

One platform for a consistent application delivery and security experience because nobody has time to learn multiple systems to manage ADC deployments. NetScaler is built with a single code base using a software-based architecture, so no matter which ADC form factor you choose — hardware, virtual machine, bare metal, or container — the behavior will be the same.

NetScaler
