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…
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

"The solution is very good at mitigating threats."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The solution provides good load balancing and protection against DDoS attacks."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Centralized, full-featured DNS."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"Cloudflare has many features."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"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."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"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 DDoS protection features are valuable."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"Packet inspection has been effective for mitigating DDoS attacks."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"The solution is very user-friendly and very easy to use."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"It allows me to see all the traffic on my network."
"The product's initial setup phase was really easy."
"We have researched them all, and it's a good solution all around."
"The product allows the users to adjust the thresholds."
 

Cons

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"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."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"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."
"There might be helpful if there was some web application firewall feature."
"Cloudflare should add more documentation and pricing to the cloud version."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"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."
"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."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The product’s pricing needs improvement."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The web interface could be much better."
"The solution can be a little more user-friendly and it can be more affordable."
 

Pricing and Cost Advice

"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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."
"The tool is a premium product, so it is very expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"I give the price a five out of ten."
"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 Corero is affordable."
"Its price is normal."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
