Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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 a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"It is a very efficient and robust appliance."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most important aspect, in general, is that the price is suitable for most clients."
"The AI capabilities and anomaly detection using machine learning modules like isolation forests and auto-encoders are the most effective in mitigating DDoS attacks."
"The solution provides good protection against volumetric DDoS attacks."
"The solution looks into volumetric attacks and gets them resolved."
"We found what we wanted in Arbor DDoS; it met our expectations as IT users of different types of complex environments and fit our needs."
"We use almost all the features of Arbor DDoS, but it really depends on the customer’s requirements, so I can’t specify exactly which features we use. However, many customers appreciate the basic DDoS protection, especially those without specific protection needs. For example, financial companies benefit from the cloud DDoS protection. It’s a straightforward solution that effectively meets their needs."
"The feature I find most valuable is the packet capture, which beautifully shows the communication between the client and the server, identifying potential malicious activity."
"Arbor DDoS offers security features that automatically detect and prevent DDoS attacks."
"In terms of Arbor DDoS's reporting and analytics, Arbor DDoS is superior to Radware, especially when comparing it to the Radware model which I used previously."
 

Cons

"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"Juniper is known in our country, but it is not very popular."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"It could use support in Spanish."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"A small improvement could be a better reporting system."
"As long as you don't touch it, it's very stable. But if you try to configure new features or some new deployment, sometimes that can be a problem."
"Arbor DDoS could improve out-of-the-box reporting, it could be better."
"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."
"In the default filter mode, there could be an impact on a customer’s link."
"There should be an automatic way to configure it to monitor traffic and decide which is an attack and which is not. In Arbor, you need to tweak and set all parameters manually, whereas in Check Point DDoS Protector, you can select the lowest parameters, and over the weeks, Check Point DDoS Protector will learn the traffic and you can then tighten some of the parameters to decide which traffic is regular and which is malicious."
"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."
"The solution's IT support needs improvement."
 

Pricing and Cost Advice

"Its price is normal."
"The price of Corero is affordable."
"The pricing of the solution is cheap."
"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."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"Pricing is slightly on the higher side."
"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."
"Start with a small license. Measure your bandwidth requirements."
"The price of this solution is a little high in the African market, it should be lower."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
