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.

Quotes from Members

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

Pros

"Arbor's technical support is very good, we've had no issues with it."
"Overall, it's a great product."
"I recommend using Arbor DDoS for those wanting to keep their services online."
"We have gained from this product, and our customers are also satisfied with this solution."
"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."
"They have done a considerable amount of development in the last few years when it comes to features."
"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."
"The most valuable features include the traffic categorization and control of the traffic. The filtering of the traffic is very precise. When you want to stop some traffic, you precisely stop that traffic."
"The product allows the users to adjust the thresholds."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"It is a user-friendly product in terms of monitoring and updating policies."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The protection resources and the support are valuable features of the solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"It allows me to see all the traffic on my network."
 

Cons

"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."
"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."
"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"Auto mitigation is a feature provided when DDoS is observed on any of link/customer (configured under auto mitigation). It automatically starts mitigation with default filters; in default filter mode, there could be an impact on the customer’s link, e.g., if we have enabled monitoring of internal traffic for that link/customer, it starts mitigation on legitimate traffic."
"I think the diversity of protection is extremely limited. It must be expanded in future upgrades and versions."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"There is definitely room for improvement in third-party intelligence and integrations."
"Earlier versions of firmware had bugs that limit my options."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"Alerts and reporting features must be improved."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"I would like to see analytics, big data."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
 

Pricing and Cost Advice

"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."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"The pricing of the solution is cheap."
"Pricing is slightly on the higher side."
"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."
"Our customers always complain about the price of the product."
"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 solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
