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…

Advanced threat protection has reduced financial risk and improves application security visibility
The issue I have with Fortinet FortiAppSec Cloud is that the real-time analysis is not robust; I am unable to see all the logs of everything that happened, including what is passive. It only logs when there are suspicious activities, which means if something is not considered suspicious by Fortinet, I will not see the full picture. That is a disadvantage because it will not log unless it identifies an IOC or attacks, meaning I cannot see traffic information in a way that helps build more intelligence. The biggest issue I have with Fortinet FortiAppSec Cloud is that the logging is not as extensive as I would prefer. For instance, if there was an issue two days ago and Fortinet FortiAppSec Cloud did not mark it as a concern, I will not see any information about that, making it challenging to explain to customers if their request did not reach us. It hampers visibility from an API perspective. They need to enhance monitoring and logging to be more extensive and capture even passive activities. The AI integration in Fortinet FortiAppSec Cloud is still new. The generative models are good, but there is much work left to improve. It is not as intelligent as it could be; thus, enhancements around the AI co-assistant would be beneficial. Additionally, logging and monitoring need improvement as I can capture traffic and investigate offline on my Fortinet firewall, including full traffic view, but Fortinet FortiAppSec Cloud currently focuses only on security concerns, which does not give the complete picture.

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."
"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."
"It is a very efficient and robust appliance."
"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."
"The most important aspect, in general, is that the price is suitable for most clients."
"The DDoS protection features are valuable."
"My favorite Fortinet device is the FortiGate next-gen firewall itself; it is a complete suite with intrusion prevention, intrusion detection, anti-malware, anti-DDoS, and SD-WAN functionalities."
"We have seen a reduction in incidents and a good return on investment from Fortinet FortiAppSec Cloud, with our return on investment around 60%."
 

Cons

"Juniper is known in our country, but it is not very popular."
"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."
"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."
"Lacks international presence."
"It could use support in Spanish."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"The issue I have with Fortinet FortiAppSec Cloud is that the real-time analysis is not robust; I am unable to see all the logs of everything that happened, including what is passive."
"Real-time traffic analysis has posed an issue for us because we did not see logs for legitimate traffic."
