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.
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…
ShashikaKodikara - PeerSpot reviewer
A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"The UI is good."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"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 features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"It's very user-friendly."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"Easier http to https redirect using page rules"
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"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."
"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."
"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 most important aspect, in general, is that the price is suitable for most clients."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"The support team was helpful."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
 

Cons

"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."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"Cloudflare should add more documentation and pricing to the cloud version."
"The product needs to improve its automation."
"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."
"DNS Management."
"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."
"The solution could be more user-friendly."
"It could use support in Spanish."
"Lacks international presence."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
 

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."
"We don't have any issues with the price."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price of the solution is expensive."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 price of Corero is affordable."
"Its price is normal."
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
