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.
Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Björn Lindman - PeerSpot reviewer
The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities
We use the solution for DDoS protection in the routers The DDoS protection features are valuable. The product must provide more Layer 7 capabilities. It must provide deep inspection features. I have been using the solution for ten years. The tool has high stability. I rate the stability a nine…

Quotes from Members

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

Pros

"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"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."
"Easier http to https redirect using page rules"
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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 attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The solution has different options that can be used to differentiate DDoS attacks."
"Cloudflare DDoS mitigates DDoS attacks."
"Enables me to work from two locations."
"This solution is easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare, in my opinion, was easy to implement."
"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."
"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."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"The DDoS protection features are valuable."
 

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The documentation could improve for Cloudflare DNS."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Support response time could be improved."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"An integrated SSO feature would be useful for Cloudflare DNS."
"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 Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Our customers no longer use Cloudflare because its service is subpar."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The initial onboarding was causing us some confusion."
"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."
"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."
"Lacks international presence."
"The product must provide more Layer 7 capabilities."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
 

Pricing and Cost Advice

"I give the price a five out of ten."
"A free version of the solution is available."
"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."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is cheap."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The cost primarily depends on the size of the organization."
"There are no additional costs beyond the standard licensing fees."
"The solution's pricing lacks transparency."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The prices are slightly expensive."

"Its price is normal."
"The price of Corero is affordable."
