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.

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."
"New and innovative way to protect the client's data."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The most valuable feature is its usability."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"I rate its stability a ten out of ten."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"It has helped us to increase the resiliency of the application and the performance."
"Citrix Director has been great. It gives us one pane of glass to be able to monitor what's going on with the user sessions as well as to keep on top of the virtual desktops, any servers that may be offline or behaving suspiciously, or any troublesome spots like disconnections. We also use Citrix Studio for maintaining the actual servers that are hosting these applications. We use it for delivery groups in case we need to modify delivery groups in regards to which groups have access to which applications. It has been very helpful."
"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."
"Provides resiliency for applications that reside on servers, as well as connectivity to remote applications."
"Load Balancing and SSL offloading are key features."
"The solution is very stable. We don't have any downtime or issues of that nature."
"My clients use it for load balancing."
"For desktop application management, I recommend the NetScaler edition. This product is like a Swiss army knife. Citrix NetScaler ADC supports the education front-end."
 

Cons

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"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."
"The vendor provides frequent patches, however, the security of the website has room for improvement."
"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."
"Citrix ADC can improve if it provides a more user-friendly interface and clear working protocols. Citrix is not working with classic RFC, it is working with Citrix RFC, which is not common in the world. If engineers of Citrix can provide us with more information on working with the classic IP networks it would be a benefit."
"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."
"Citrix is more expensive than Horizon."
"The solution can improve their support and send tickets directly to a Citrix ADC engineer in order to avoid having to escalate each support call."
"Too many bugs in the software and it's always difficult when you need to update."
"Some features of Citrix ADM are available on the cloud, which could really be helpful if they were available on an on-premise version."
 

Pricing and Cost Advice

"We are using the free version."
"The price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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."
"A free version of the solution is available."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The licensing costs for this solution vary depending on which model is being used."
"We have a yearly licencing fee, and there are no additional costs."
"It all depends on the features that will be used and the number of accesses."
"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."
"I rate the tool's pricing an eight out of ten."
"It's an expensive product but it works well."
"The pricing for Citrix Web App and API Protection is unreasonable. I don't know the exact price, but I heard it's tens of thousands and it's a bit too much for the small country I live in."
"Citrix NetScaler's pricing is slightly above average but not overly expensive. I would consider F5 BIG IP to be the most expensive, Citrix NetScaler to be the second most expensive, and then Kemp Load Balancer to be the third."
