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.

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 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 is the web application firewall."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"The solution provides good load balancing and protection against DDoS attacks."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The UI is good."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"From what I've seen so far, there are no negatives to report as of yet"
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"This is a hybrid solution."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The most important aspect, in general, is that the price is suitable for most clients."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"The DDoS protection features are valuable."
 

Cons

"There might be helpful if there was some web application firewall feature."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"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."
"The product needs to improve its automation."
"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."
"The product must provide more Layer 7 capabilities."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Lacks international presence."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
 

Pricing and Cost Advice

"I give the price a five out of ten."
"The cost primarily depends on the size of the organization."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"The product's pricing is minimal compared to other products."
"The product's pricing is cheap."
"Its price is normal."
"The price of Corero is affordable."
