Reliable protection ensures robust network defense and simplifies DDoS management
I am not sure if we plan to use additional features because we have many vendors and platforms that we support. We use the main function and that is it. The prices for Arbor DDoS are expensive. The licensing is subscription-based. From our sales department, they discuss that prices are very high. A potential improvement could be establishing a contract with Cisco to sell via their channel. This could be beneficial because we work extensively with Cisco. If you are a Cisco partner, you can sell Arbor DDoS. That would be good for customers that are Cisco-based because many customers in Bosnia are Cisco-based customers. BH Telecom, our main customer, sells Arbor DDoS to other customers for protection. They buy Arbor and sell the product services to others via Internet links. They sell add-on DDoS protection via Arbor DDoS. In Bosnia and Herzegovina, Arbor DDoS is not present in many customers. Some customers try to sell it, but they sell other vendors such as F5. Arbor DDoS is mainly seen in telecom operators but not much in other customers.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"The auto-mitigation, that signaling feature, where it automatically raises an alarm that a line is under attack, is important. The upstream service provider will then do something to reduce the load on our internet lines. The fact that it's automated means I don't have to sit and always be looking at threats coming through. It does it almost automatically, without any intervention by me."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"Our customers are very happy when we provide them with the interface... They can check how many attacks they have faced and how many attacks have been blocked."
"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."
"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."
"The solution looks into volumetric attacks and gets them resolved."
"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 solution is flexible, easy to implement and has an efficient technical support team."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"I find the interface easy to use."
"The product allows the users to adjust the thresholds."
"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."
"We have researched them all, and it's a good solution all around."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product's initial setup phase was really easy."
 

Cons

"An issue which needs to be addressed concerns information I received of attacks on the radar and Arbor, allegedly, not taking any action."
"The regional support here in African could improve, such as marketing and account managers."
"If we want to see live traffic, we can see do so. But once an attack that lasts for five minutes is done, the data is no longer there. It would be an improvement if we could see recent traffic in the dashboard. We can check and download live traffic, but a past attack, with all the details, such as why it happened and how to mitigate and prevent such future attacks, would be helpful to see."
"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."
"There is some room for AI to take place."
"It could include a lot of enhancements related to AI and automation."
"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."
"I think Arbor DDoS needs improvement in areas where competitors like S5, Redver, or NETSCOUT offer web application firewall functionality or dedicated web application firewall devices. Arbor lacks these features, which is a significant disadvantage. Yes, I would like to see these features introduced in Arbor as well. Regarding real-time detection capabilities, Arbor DDoS works very well. We and our customers are very satisfied with its performance. However, it would benefit from adding Web Application Firewall (WAF) capabilities to reach a larger customer base."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"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."
"Alerts and reporting features must be improved."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
 

Pricing and Cost Advice

"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"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 solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"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."
"It is an expensive product. I use this product for its different features."
"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."
"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."
"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
