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.

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."
"It is a fast and secure DNS."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Generally, I am satisfied with this product."
"New and innovative way to protect the client's data."
"The control panel is nicely laid out and I do not have to hunt for functionality."
"It has improved our organization by providing quick access to resources."
"I selected CDN77 because it has servers where our different target markets are (some are in Asia)."
"It is extremely easy to set up and integrate with WordPress and purge files as needed through the control panel."
"It has helped improve load speed on the site."
"​Purge pages: It is a fast solution for updating my content from all datacenters."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"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."
"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."
 

Cons

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"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."
"There should be a specific price list for enterprise-level customers."
"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."
"If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use."
"A year ago, I had to deal with SEO factors involving duplication of content."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"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."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
 

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."
"A free version of the solution is available."
"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."
"The price of the solution is expensive."
"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 don't have any issues with the price."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free tier of the solution."
"I would suggest low usage cases that there are other options available, such as WordPress's own CDN."
"For low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users."
"Regarding the pricing, it is expensive. It may not suit others. I suggest a lower recharge level and also to remove the credit expiry time​."
"The price of Corero is affordable."
"Its price is normal."
