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.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through
Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"From what I've seen so far, there are no negatives to report as of yet"
"Centralized, full-featured DNS."
"The most valuable feature is its usability."
"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 most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare has many features."
"The most valuable feature is its usability."
"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."
"The three-second service level agreement is already better than the competition."
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
"The solution is very good at intercepting traffic before it gets to our data centers."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"Imperva Incapsula has many valuable features. One, it protects the top 10 OWAS vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"It blocks all types of attacks."
"The solution's most valuable aspect is that it is easy to configure."
"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."
 

Cons

"The documentation could improve for Cloudflare DNS."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"Technical support is lacking."
"DNS Management."
"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."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Latencies are always a problem."
"Certificate management could be improved."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"A limited tool if you're looking to customize."
"The cost could be lower; our end clients need to have a high budget to purchase this solution."
"It's quite expensive."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"We had an issue when securing the web applications for DDoS protection."
"Some maintenance must be performed by our IT team."
"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."
 

Pricing and Cost Advice

"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."
"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."
"We are using the free version."
"I give the price a five out of ten."
"The product's pricing is cheap."
"We don't have any issues with the price."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"That is one of the great features. I was able to access the majority of the features and services for free."
"Varies depending on the needs of the customer."
"The solution's price is high for small companies."
"Pricing could be more competitive."
"The license is on a yearly basis."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"It is expensive."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"There is a license or subscription renewal that our customers pay."
