Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.

Application gateway optimizes performance and simplifies cloud transitions
There are a lot of things I appreciate about Microsoft Azure Application Gateway. Microsoft Azure Application Gateway is beneficial for us as it helps in publishing our website, providing us comfort when it comes to the availability of our applications. The autoscaling feature in Microsoft Azure Application Gateway is very obvious, and I have no issues with it; it is well planned and organized. Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance. The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats. Microsoft Azure Application Gateway helps us manage our AI-driven applications by enabling faster transactions, improving our work.

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

"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."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The technical support is good."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"It is a fast and secure DNS."
"Centralized, full-featured DNS."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The tool is easy to use and quite flexible. It has policy management features as well. The solution screens all traffic to our web applications before passing it to the application. We recently tested it on one of our poorly developed applications, and the upgrade gave us a 100% result based on our tests. It's very effective as a security measure, and people can detect threats even through the web application."
"Some of the key features of this solution are the low-level maintenance required, floating proxy service, and load balancing."
"The health probe is pretty good for your backend health. It tells you whether it's communicating and talking to the endpoint correctly. It is quite useful."
"It has a filter available, although we are not currently using it because it is not part of our requirements. But it is a good option and when it becomes part of our requirements we will definitely use it."
"Azure Application Gateway's most valuable feature is ease of use. The configuration is straightforward. It isn't difficult to adjust the size of your instances in the settings. You can do that with a few clicks, and the configuration file is the same way. You can also set rules and policies with minimal time and effort."
"The most valuable feature of Microsoft Azure Application Gateway is its ease of use."
"I find Application Gateway’s WAF module valuable because it helps prevent layer 7 attacks."
"The product's initial setup phase was easy."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"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 valuable features of Citrix ADC are load balancing and application firewall."
"The load balancing feature of this solution is very good."
"Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."
"The load balancing is one of the most valuable features."
"HTTP analysis and action. We have a lot of custom web applications that sometimes require custom header insertions. Some of these custom apps are external and, via the content switching, we can use one IP and leverage various back-end web app servers."
"Easy, user-friendly setup with content switching and integrated caching features."
 

Cons

"Latencies are always a problem."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"DNS Management."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"The analytics, basically the dashboard, doesn't have much to it."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"Technical support is lacking."
"The product's performance should be better."
"The solution could improve by increasing the performance when doing updates. For example, if I change the certificate it can take 30 minutes. Other vendors do not have this type of problem."
"In future releases of Microsoft Azure Application Gateway, I would to see more AI functionalities and a better dashboard as well as some customizations."
"The product could be easier to use and implement."
"It does not have the flexibility for using public IPs in version 2."
"The pricing of the solution is a bit high. The solution should offer different pricing systems."
"The solution is easy to use overall, but the dashboard could be updated with a better layout and graphical design so that we can see the data a bit easier. Microsoft could also add more documentation. The documentation Microsoft provides doesn't tell us about resource requirements. We found that the instances we had weren't sufficient to support the firewall, so we had to increase them."
"The tool is a pain to deal with when it comes to the area of configuration."
"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."
"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."
"Does not include security. A web application firewall would be a nice addition."
"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."
"The security is okay, but the monitoring and reporting need improvement."
"ADC from Citrix has added functionalities from other products and the usability is very difficult for someone who is used to a simpler user interface, it's a little bit of a mess to use."
"The GUI should be improved."
"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."
 

Pricing and Cost Advice

"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"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."
"There are no additional costs beyond the standard licensing fees."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"I give the price a five out of ten."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The price of the solution can be reduced a bit."
"I rate the pricing seven out of ten because some third-party solutions are even costlier than this."
"The product is expensive. I rate the pricing a seven out of ten."
"We use the tool's basic subscription. Its licensing costs are monthly."
"The pricing is based on how much you use the solution."
"Regarding pricing for Azure Application Gateway, I would rate it at seven."
"The solution is reasonably priced compared to other solutions."
"Microsoft Azure Application Gateway is expensive."
"The tool is cheap."
"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 all depends on the features that will be used and the number of accesses."
"It is an enterprise solution. Thus, its costs are reasonable."
"Its price is comparable to others and affordable."
"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"
"The license for Citrix NetScaler is on an annual basis and it is reasonably priced."
"I give the price of the solution a seven out of ten."
