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.

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

"Easier http to https redirect using page rules"
"The most valuable feature is its usability."
"The most valuable feature is its usability."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"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."
"The solution is stable, and the DNS servers are simple to use."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"This is a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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."
"The DDoS protection features are valuable."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"Protection is the best solution since it has profile functionality."
"It's very pretty easy to onboard the URL."
"The solution integrates seamlessly with other tools and has a good alert mechanism."
"Technical support was very helpful."
"The solution is very good at intercepting traffic before it gets to our data centers."
 

Cons

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"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."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"DNS Management."
"The documentation could improve for Cloudflare DNS."
"Technical support is lacking."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
"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."
"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."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"I miss being able to integrate the dashboard with other BI tools we are using. We have to export and import data to be able to present it, and doing so is a lot of work."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"If they can bring in generative AI features, that would be useful."
"The rules surrounding the making of web applications could be improved."
"It's a complicated tool to keep."
"Certificate management could be improved."
"We had an issue when securing the web applications for DDoS protection."
 

Pricing and Cost Advice

"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 pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"The price of the solution is expensive."
"A free version of the solution is available."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The price of Corero is affordable."
"Its price is normal."
"Imperva Web Application Firewall's pricing is expensive."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"The license is on a yearly basis."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"Imperva Web Application Firewall is expensive."
"We are satisfied with the pricing."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
