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 most valuable feature is the web application firewall."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"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."
"It is a fast and secure DNS."
"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."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"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."
"The most valuable feature is the cloud DDoS scrubbing capability."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"The product's initial setup phase was really easy."
"The product allows the users to adjust the thresholds."
"It allows me to see all the traffic on my network."
"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."
"I find the interface easy to use."
"I have found the system to be very intuitive, functional, and they have great technology."
"The installation is straightforward, it took a couple of hours."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"This is the most scalable product of its type."
"It's a beneficial tool."
"We are happy with the scalability."
"I am impressed with the tool's protection."
"Provides protection for virtual machines."
 

Cons

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"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."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"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."
"The solution could be more user-friendly."
"The web interface could be much better."
"The solution can be a little more user-friendly and it can be more affordable."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The product’s pricing needs improvement."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution could improve by having a more streamlined setup."
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of knowledge."
"The initial setup for VMware NSX is a bit complex; it's not as simple as it could be."
"There could be an improvement in regards to security."
"If there are other solutions already in place, it can be difficult to implement."
"The support from VMware NSX could improve."
 

Pricing and Cost Advice

"That is one of the great features. I was able to access the majority of the features and services for free."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The price is reasonable."
"We are using the free version."
"The price of the solution is expensive."
"We don't have any issues with the price."
"I give the price a five out of ten."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
"We have saved man-hours and decreased our security exposure."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"The price of VMware NSX is reasonable."
"The price is significantly high and it can be a hurdle for many potential users."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
