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.

Enhanced security and streamlined management drive efficient connectivity
Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.

Quotes from Members

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

Pros

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"Cloudflare has many features."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The tool is user-friendly."
"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 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 DNS is its global reach and it is always evolving."
"The UI is good."
"The solution is very user-friendly and very easy to use."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"The product allows the users to adjust the thresholds."
"The product's initial setup phase was really easy."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The equipment works very well, and I have not encountered any issues with it."
"We have researched them all, and it's a good solution all around."
"It is a user-friendly product in terms of monitoring and updating policies."
"From a distributed firewall perspective, it's a solid solution."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"We are happy with the scalability."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require."
"The initial setup was straightforward. It follows a certain structure and you won't miss a step. It's all on the same level, step by step."
"The initial setup was straightforward. You just have to click it and follow the manuals."
 

Cons

"The pricing could be improved."
"Cloudflare should add more documentation and pricing to the cloud version."
"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."
"The analytics, basically the dashboard, doesn't have much to it."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"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."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The solution can be a little more user-friendly and it can be more affordable."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The product’s pricing needs improvement."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Alerts and reporting features must be improved."
"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."
"I would like them to make integration with other vendors easier."
"It's not feature-rich."
"It was stable for one year, there was no impact. In the last two months, we had two big incidents."
"It isn't easy to deploy."
"The price is rather high."
"It needs to be cheaper."
"In the future, the solution should be compliant with internet NIC."
"The first time setting it up was difficult."

"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."

"The price is significantly high and it can be a hurdle for many potential users."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
