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.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through

Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"The solution provides good protection against volumetric DDoS attacks."

"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."

"Arbor has a global ranking in reliability and credibility. They are very unique and can respond to a very wide scope of threats from their global deployment."

"The stability is okay and we have not encountered problems with the solution."

"I recommend using Arbor DDoS for those wanting to keep their services online."

"The analytics part of Arbor DDoS is great, and we are satisfied with the reporting and analytics part, especially the new version."

"There are a number of valuable features in this product, like Cloud Signaling and Threat Intelligence feeds."

"The most valuable feature is mitigation, which can blackhole the IP."

More Arbor DDoS pros

"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."

Cons

"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 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."

"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."

"Arbor Pravail APS devices do not sync features or config the backup enough. This needs to be improved."

"They also have limited sizes of the boxes. Different sizes are needed because some customers are very small while others are very big, such as ISPs, so this categorization should be available."

"There is definitely room for improvement in third-party intelligence and integrations."

"Real-case scenarios that have taken too long to resolve or were escalated can be directly converted into articles."

More Arbor DDoS cons

"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."

Pricing and Cost Advice

"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."

"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."

"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."

"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."

"We do not use the Arbor Cloud DDoS solution because it is too costly."

"The solution's pricing is based on a licensing model that is expensive when compared to other tools."

"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."

"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."
