It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

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.
ÖS
Eliminated DDOS attacks, provides excellent mitigation service
I rate it eight out of 10. It would get a nine if the web portal was better and 10 if the price was lower. We have been using it for three years. We canceled the contract recently and are looking into using another vendor to reduce the price by two-thirds.

Quotes from Members

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

Pros

"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."
"Cloudflare has many features."
"The solution is very good at mitigating threats."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"New and innovative way to protect the client's data."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"The DDoS protection is the most valuable aspect of the solution."
"Centralized, full-featured DNS."
"I find the interface easy to use."
"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 protection resources and the support are valuable features of the solution."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The solution is very user-friendly and very easy to use."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The product's initial setup phase was really easy."
"Packet inspection has been effective for mitigating DDoS attacks."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
 

Cons

"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."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"Technical support is lacking."
"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"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."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The web interface could be much better."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"I would like to see analytics, big data."
"The product’s pricing needs improvement."
"The solution needs additional product options for small and medium enterprises."
 

Pricing and Cost Advice

"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."
"I give the price a five out of ten."
"The price is reasonable."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"A free version of the solution is available."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
"The pricing is a pay-as-you-go model that is charged by the hour."
