It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Effect local attack handling, intuitive interface, and scalable
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.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"Smaller businesses have seen great ROI due to the low investment and strong performance."
"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 a fast and secure DNS."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The technical support is good."
"Generally, I am satisfied with this product."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"I rate its stability a ten out of ten."
"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 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 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."
"This is a hybrid solution."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"I find the interface easy to use."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"We have researched them all, and it's a good solution all around."
"The solution is very user-friendly and very easy to use."
"Packet inspection has been effective for mitigating DDoS attacks."
"It allows me to see all the traffic on my network."
"The protection resources and the support are valuable features of the solution."
"The most valuable feature is the cloud DDoS scrubbing capability."
 

Cons

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"The product support needs to be accessible from more places, a wider area of coverage."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"The documentation could improve 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."
"Latencies are always a problem."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"It could use support in Spanish."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The product’s pricing needs improvement."
"The solution can be a little more user-friendly and it can be more affordable."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The web interface could be much better."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"Alerts and reporting features must be improved."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"The tool is a premium product, so it is very expensive."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"We are using the free version."
"We don't have any issues with the price."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"Its price is normal."
"The price of Corero is affordable."
"It's quite pricey."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
