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.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.
IshtiaqKhalil - PeerSpot reviewer
Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"It is a fast and secure DNS."
"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."
"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."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The technical support is good."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The product allows the users to adjust the thresholds."
"Packet inspection has been effective for mitigating DDoS attacks."
"It allows me to see all the traffic on my network."
"I find the interface easy to use."
"The solution is very user-friendly and very easy to use."
"It is a user-friendly product in terms of monitoring and updating policies."
"The equipment works very well, and I have not encountered any issues with it."
"The most valuable feature is the load balancing and allowing for high availability of our web services."
"The feature that allows us to easily disconnect a server when we need and bring back online is the most valuable. It's a click of a button. This allows us to keep all systems up. We can then run updates, perform reboots whatever we need to one of the servers without taking production down."
"The DNS Load Balancer makes it so that I don't have to worry about site failures."
"One of the most valuable features I like is the ability to block specific cipher suites like RC4, and older protocols like SSL 3.0."
"We really like the performance of this solution."
"I like the way this solution handles multiple SSLs in different domains while still load balancing."
"The user interface is very easy to work with."
"Great web balancing and remote access balancing."
 

Cons

"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"There might be helpful if there was some web application firewall feature."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Latencies are always a problem."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"I would like to see analytics, big data."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see more automation and control of overactive and inactive resources. If I could schedule these around our updates then it would be all automated. I would like to set up an automated script to coincide with the scripts I use to update resources and servers."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"I think there should be more visual instructions on how to configure advanced features."
"In the next release, they can introduce 360 views in the same dashboard to make it easier for users to view. The graphical information should be displayed on the dashboard."
"The only thing I have struggled with is setting up automatic backups."
"We experienced a brief period of instability."
"It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."
"If you want logging for SMTP traffic, you have to enable ESP, which requires you to define allowed IP addresses. That’s irritating, to say the least."
 

Pricing and Cost Advice

"The price is reasonable."
"We are using the free version."
"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."
"A free version of the solution is available."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is minimal compared to other products."
"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."
"We don't have any issues with the price."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"KEMP gives away free trials for 30 days. This can be stretched if you want. During the test, you will have access to KEMP support.​"
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"Less expensive than Citrix."
"The price is lower than other options."
"The product definitely provides what the organization needs and its cost is reasonable considering the value it brings."
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"The price is great and the value is definitely there."
