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

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"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."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"It is a very efficient and robust appliance."
"Analytics and its attack mitigation capabilities are valuable features of the solution."
"Because this Arbor DDoS product is the best, I do not need to spend time supporting it."
"It is fully mitigating the attacks. We've dealt with other ones where we didn't necessarily see that. The detection is very good. It's also very simple to use. Arbor is a single pane of glass, whereas with other solutions you might have a detection pane of glass and then have to go to a separate interface to deal with the mitigation. That single pane of glass makes it much simpler."
"We have gained from this product, and our customers are also satisfied with this solution."
"The quality of the technical support provided by Arbor DDoS is premium."
"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."
"I am convinced with the kind of scalability Arbor brings in; the Cloud subscription, which is available as one of its features, makes the scalability limitless."
"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."
 

Cons

"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."
"It could use support in Spanish."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Lacks international presence."
"Juniper is known in our country, but it is not very popular."
"The product must provide more Layer 7 capabilities."
"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."
"Sometimes it blocks legitimate traffic. If a legitimate user is trying to access the server continuously, the product suspects that this is a DoS traffic file. That is a case where it needs to improve. It needs machine-learning."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"The look and feel of the management console is a little old, excessively simple. If you compare it with other solutions, the look and feel of the console is like you're using technology from five or six years ago. It doesn't show all the technology that is actually behind it. It looks like an older solution, even though it is not."
"The implementation should be made easier."
"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."
"A small improvement could be a better reporting system."
"For troubleshooting problems, it's not so intuitive. It's not straightforward."
"Sometimes it is not able to filter traffic adequately because of the hybrid approach."
 

Pricing and Cost Advice

"Its price is normal."
"The price of Corero is affordable."
"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."
"Our customers always complain about the price of the product."
"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."
"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."
"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
