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

"It is extremely easy to set up and integrate with WordPress and purge files as needed through the control panel."
"I selected CDN77 because it has servers where our different target markets are (some are in Asia)."
"​Purge pages: It is a fast solution for updating my content from all datacenters."
"It has improved our organization by providing quick access to resources."
"The control panel is nicely laid out and I do not have to hunt for functionality."
"CDN77 has helped improve load speed on the site."
"It is user-friendly and has a very easy GUI."
"We are able to respond quickly and prevent DDoS attacks."
"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 has a global ranking in reliability and credibility and is very unique in its ability to respond to a very wide scope of threats from its global deployment."
"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 has an easy-to-understand GUI...Stability-wise, I rate the solution a ten out of ten."
"There were huge attacks in October, around 62 attacks at 30 gigabits per second, at one of our banks. We used Arbor DDoS to mitigate these attacks, and it performed great."
"Arbor DDoS is used for network protection if you have a DDoS attack, it keeps the session or information moving."
 

Cons

"Regarding the pricing, it is expensive. It may not suit others."
"If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use."
"A year ago, I had to deal with SEO factors involving duplication of content."
"For troubleshooting problems, it's not so intuitive. It's not straightforward."
"In the default filter mode, there could be an impact on a customer’s link."
"I think the diversity of protection is extremely limited. It must be expanded in future upgrades and versions."
"Because we had some routers that were somewhat old, they were not integrated with Arbor. They did not support the NetFlow version that Arbor was running. That was a challenge. We had to upgrade the routers. Some backward-compatibility would be helpful."
"New versions are sometimes released before the bugs are worked out."
"There is some room for AI to take place."
"An issue which needs to be addressed concerns information I received of attacks on the radar and Arbor, allegedly, not taking any action."
"Implementation could be better."
 

Pricing and Cost Advice

"I would suggest low usage cases that there are other options available, such as WordPress's own CDN."
"Regarding the pricing, it is expensive. It may not suit others. I suggest a lower recharge level and also to remove the credit expiry time​."
"For low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users."
"Our customers always complain about the price of the product."
"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"It is an expensive product. I use this product for its different features."
"The price of this solution is a little high in the African market, it should be lower."
"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"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."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
