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…

Quotes from Members

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

Pros

"The DDoS protection features are valuable."
"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. It is simple and works well if you have Juniper MX routers."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"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."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"I find the interface easy to use."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The protection resources and the support are valuable features of the solution."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"It allows me to see all the traffic on my network."
"The solution is very user-friendly and very easy to use."
"Packet inspection has been effective for mitigating DDoS attacks."
 

Cons

"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."
"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."
"The product must provide more Layer 7 capabilities."
"The solution can be a little more user-friendly and it can be more affordable."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"Alerts and reporting features must be improved."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
