Automated threat intelligence and flow-based mitigation have improved our DDoS defense
A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.

Reliable protection and smooth setup enhance company security

Quotes from Members

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

Pros

"There are a number of valuable features in this product, like Cloud Signaling and Threat Intelligence feeds."
"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."
"The stability is okay and we have not encountered problems with the solution."
"We are able to respond quickly and prevent DDoS attacks."
"The AI capabilities and anomaly detection using machine learning modules like isolation forests and auto-encoders are the most effective in mitigating DDoS attacks."
"Reporting is quite good. There are several pages of reporting on DDoS attacks, and you can find all the details that you need."
"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."
"We also use it by serving our customers' cloud signaling services with on-premise APS devices."
"The product's initial setup phase was really easy."
"It allows me to see all the traffic on my network."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"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."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The solution is very user-friendly and very easy to use."
"The protection resources and the support are valuable features of the solution."
 

Cons

"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."
"There are some price issues with scalability, but technically speaking, the solution is fully scalable."
"There is always room for improvement for any product or service. If we can bring in more agility when deploying services, that is definitely a scope which we can work towards. Nowadays, everything is being offered as a service model. It is not that we have to deploy the physical hardware, many things move up to the cloud, or even can be delivered in the VNS form in the customer's environment as well. So, in that space, if we can add more features to make it more seamless for customers to use and make it available through some marketplace, not only at the hyperscalers, but also for any on-prem deployment, that definitely would be a big plus."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"Unfortunately, these devices are not scalable and we have to upgrade to the next model in order to increase the threat mitigation capabilities."
"The solution could be more granular to include logs per second and enhanced pipeline monitoring for router licenses."
"It could include a lot of enhancements related to AI and automation."
"Earlier versions of firmware had bugs that limit my options."
"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."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"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."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"I would like to see analytics, big data."
 

Pricing and Cost Advice

"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."
"The price is a little high."
"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."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"Pricing is slightly on the higher side."
"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."
"The pricing of the solution is cheap."
"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
