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

"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."
"The tool is user-friendly."
"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 overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"The most valuable feature is the web application firewall."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The solution is easy to use."
"I highly recommend Arbor DDoS to others."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"There were huge attacks in October, around 62 attacks at 30 gigabits per second, at one of our banks. We used Arbor DDoS to mitigate these attacks, and it performed great."
"It's just one dashboard with mitigation. You decide which mitigation you want and at what threshold to do this or that. Its operation is pretty simple. It's easy."
"In the GUI, the packet capture is a very good option, as is the option to block an IP address."
"It's very flexible and we can easily deploy it to our network. It's very user-friendly. We can do everything via the web interface and troubleshoot easily from the CLI. It's not complicated."
"The stateless device format means that the box is very strong for preventing DDoS attacks."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"The most valuable feature is the cloud DDoS scrubbing capability."
"Packet inspection has been effective for mitigating DDoS attacks."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The equipment works very well, and I have not encountered any issues with it."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"We have researched them all, and it's a good solution all around."
"The solution is very user-friendly and very easy to use."
 

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"There might be helpful if there was some web application firewall feature."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"There are some issues with the CDN services."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"There should be a specific price list for enterprise-level customers."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The solution needs to enhance its features to compete with other tools."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"On the main page there are alerts that we are unable to clear, even though the issue has been resolved."
"I would also like more visibility into their bad actor feeds, their fingerprint feeds. We try to be good stewards of the internet, so if there are attacks, or bad actors within our networks, if there were an easier way for us to find them, we could stop them from doing their malicious activity, and at the same time save money."
"It is an expensive product, so there is room for improvement in terms of pricing."
"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."
"The implementation should be made easier."
"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Alerts and reporting features must be improved."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
 

Pricing and Cost Advice

"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"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 tool is a premium product, so it is very expensive."
"The price is reasonable."
"The product's pricing is minimal compared to other products."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
"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."
"The pricing of the solution is cheap."
"Start with a small license. Measure your bandwidth requirements."
"The price is a little high."
"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"Because the solutions from competitors are very different, it's not easy to compare. However, the licensing from Arbor is clear and understandable and the pricing is reasonable when looking at the market, in general."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
