Featured Reviews

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.
Manikandan-R - PeerSpot reviewer
Solution provides essential protection with good support and a simple setup
I have noticed a pattern developing in approximately five minutes. If it were possible to provide these patterns with historical data spanning six months, three months, or two months directly from the console, it would be extremely beneficial. It would allow for easy inquiries and facilitate the retrieval of relevant parts without having to manually check logs or examine movements. Instead, if all historical data were available, I could consult six months' worth of identified patterns efficiently through AWS without relying on external sources. This solution is particularly suitable for startups or medium-sized startups. I would rate the overall solution eight out of ten.
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.

Quotes from Members

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

Pros

"I rate its stability a ten out of ten."
"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."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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."
"From what I've seen so far, there are no negatives to report as of yet"
"The most valuable feature is its usability."
"The tool is user-friendly."
"New and innovative way to protect the client's data."
"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"The solution's ease of use is the most valuable feature."
"I am impressed with the product's multiple features like security."
"It is quite scalable, and we have not faced any issues with its scalability."
"The product has a good mechanism to analyze trends and trigger events."
"The product is easy to use."
"It is integrated with AWS. So, it gives you a good first step."
"The product allows the users to adjust the thresholds."
"The protection resources and the support are valuable features of the solution."
"It is a user-friendly product in terms of monitoring and updating policies."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"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."
"I find the interface easy to use."
"It allows me to see all the traffic on my network."
"The equipment works very well, and I have not encountered any issues with it."
 

Cons

"There should be a specific price list for enterprise-level customers."
"The documentation could improve for Cloudflare DNS."
"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."
"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."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"The product is expensive."
"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."
"The product needs to improve its logs and reports to make it read better."
"We end up having to pay extra for features that AWS adds that we don't need."
"The time taken to detect anomalies must be reduced."
"Perhaps the time required to detect anomalies can be reduced."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The web interface could be much better."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"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 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."
"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."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"There are no additional costs beyond the standard licensing fees."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"A free version of the solution is available."
"The tool's pricing is good."
"We pay $3000 per month for the solution."
"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."
"The tool is cheap."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
