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.

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.
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

"We have taken on the Arbor Cloud subscription, which is really useful because you secure yourself for anything beyond your current mitigation capacity. This is a really good feature of Arbor that is available."
"Reporting is quite good. There are several pages of reporting on DDoS attacks, and you can find all the details that you need."
"It has an easy-to-understand GUI...Stability-wise, I rate the solution a ten out of ten."
"Arbor DDoS is easy to use, provides effective blocking of DDoS attacks, and can be used for DNS, web, and main servers. Additionally, this solution is far easier to operate than others solutions, such as Fortinet DDoS."
"It provides packet capture and we can block or whitelist whichever IPs we need to. Whatever traffic we want to block - and we get IPs from internal teams and from national teams - we block at the Arbor level only, because if it gets to the firewall then firewall bandwidth will be taken."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"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..."
"Inside this product, there are many different configurations for protection, and we have one of the best experiences with it, specifically with the Atlas product."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The solution offers the flexibility to control configuration rules."
"The most valuable feature of Cloudflare DNS is security."
"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."
"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."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"New and innovative way to protect the client's data."
"The protection resources and the support are valuable features of the solution."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
"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."
"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 equipment works very well, and I have not encountered any issues with it."
 

Cons

"The implementation should be made easier."
"The support got worse after NETSCOUT acquired Arbor."
"The product could have end-to-end platform visibility."
"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."
"When it comes to some false positives, we need to tweak the system from time to time. There is room for improvement when it comes to the actual mitigation because of some false positives."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"Support in Argentina is not so good. Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers."
"We need a SaaS model for the solution."
"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 product needs to improve its automation."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"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 main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"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."
"Alerts and reporting features must be improved."
 

Pricing and Cost Advice

"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"The price of Arbor DDoS depends on many parameters. It depends on the physical capacity of the environment, and it is not a straight-line price. It's fairly competitive in the market on the price."
"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."
"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."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"Our customers always complain about the price of the product."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"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."
"The price is reasonable."
"We are using the free version."
"The cost primarily depends on the size of the organization."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"We don't have any issues with the price."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
