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.
Hamada Elewa - PeerSpot reviewer
Users have experienced comprehensive protection against DDoS threats while enjoying seamless integration
The most valuable feature of Arbor DDoS is that it is based in most of the ISPs all over the world, and Egyptian ISPs are one of them. If a customer who is getting internet connectivity from one of the ISPs has an Arbor at the end, it will be integrated with the ISP Arbor. It's some sort of closing all the cycle with Arbor DDoS, from the ISP sides and from your side as a customer. Traffic analysis with Arbor DDoS is very good; it is brilliant. They act in a different way compared to others, and the vendor support is very good. The main benefits Arbor DDoS provides to users include stopping DDoS attacks, which is the biggest nightmare for all customers.
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 most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The most valuable feature is the web application firewall."
"The solution offers the flexibility to control configuration rules."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"New and innovative way to protect the client's data."
"Because this Arbor DDoS product is the best, I do not need to spend time supporting it."
"The artificial intelligence feature is most appreciated. This solution can lower the throughput and clear the traffic, which is something really important for us. It also provides good protection. It is user-friendly, and its integration has also been really fast. We have many critical applications, and it was easy to integrate Arbor DDoS with our website, mobile application, and web banking."
"Arbor DDoS offers security features that automatically detect and prevent DDoS attacks."
"The feature I find most valuable is the packet capture, which beautifully shows the communication between the client and the server, identifying potential malicious activity."
"There are a number of valuable features in this product, like Cloud Signaling and Threat Intelligence feeds."
"We use it not only for DDoS detection and protection, but we also use it for traffic analysis and capacity planning as well. We've also been able to extend the use of it to other security measures within our company, the front-line defense, not only for DDoS, but for any kind of scanning malware that may be picked up. It's also used for outbound attacks, which has helped us mitigate those and lower our bandwidth costs..."
"I highly recommend Arbor DDoS to others."
"It has an easy-to-understand GUI...Stability-wise, I rate the solution a ten out of ten."
"Packet inspection has been effective for mitigating DDoS attacks."
"The solution is very user-friendly and very 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."
"The most valuable feature is the cloud DDoS scrubbing capability."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The product allows the users to adjust the thresholds."
"It allows me to see all the traffic on my network."
"The equipment works very well, and I have not encountered any issues with it."
 

Cons

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"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 solution could be more user-friendly."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"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."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The solution could work at being less expensive. It costs a lot to use it."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"The regional support here in African could improve, such as marketing and account managers."
"On the application layer, they could have a better distributed traffic flow. They could improve that a bit. For network data it is very effective, but the application layer can be improved."
"For troubleshooting problems, it's not so intuitive. It's not straightforward. This is the core of their kernel, so they need to improve it a little bit... In F5 I have full control of everything."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."
"The look and feel of the management console is a little old, excessively simple. If you compare it with other solutions, the look and feel of the console is like you're using technology from five or six years ago. It doesn't show all the technology that is actually behind it. It looks like an older solution, even though it is not."
"A small improvement could be a better reporting system."
"An issue which needs to be addressed concerns information I received of attacks on the radar and Arbor, allegedly, not taking any action."
"I would like to see analytics, big data."
"The web interface could be much better."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The solution can be a little more user-friendly and it can be more affordable."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"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 product's pricing is minimal compared to other products."
"That is one of the great features. I was able to access the majority of the features and services for free."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The price is reasonable."
"We are using the free tier of the solution."
"I don't know about the pricing details as our company's service provider offers us the solution as an inbuilt feature within the internet bandwidth they provide us."
"I'm a technical guy. But I know it's expensive compared to its competitors. After you have the on-premise solution, for your solution to be effective you have to subscribe to an "upper level," so there's another cost. There is also a subscription to cloud services, which is another cost."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"The price is a little high."
"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."
"Pricing is slightly on the higher side."
"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"Start with a small license. Measure your bandwidth requirements."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
