Effective network and DDoS protection with suitable pricing

"This is a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a very efficient and robust appliance."
"The DDoS protection features are valuable."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"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."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The product's initial setup phase was really easy."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product allows the users to adjust the thresholds."
"The most valuable feature is the cloud DDoS scrubbing capability."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
 

Cons

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
"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."
"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."
"Lacks international presence."
"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."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"Alerts and reporting features must be improved."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I would like to see analytics, big data."
"The initial setup is complex. It is always complex."
