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.

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

"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%."
"Arbor DDoS helps consolidate visibility on traffic and on DDOS attacks attempts, can perform direct mitigation action on the network, and has helped us achieve our network and application uptime goals."
"Arbor Pravail APS devices provide easy management, high visibility, and quick response capabilities."
"Arbor has a global ranking in reliability and credibility and is very unique in its ability to respond to a very wide scope of threats from its global deployment."
"The Arbor Networks SP device provided great visualization of the network traffic."
"Arbor DDoS is used for network protection if you have a DDoS attack, it keeps the session or information moving."
"The solution provides good protection against volumetric DDoS attacks."
"We have gained from this product, and our customers are also satisfied with this solution."
"With real-time packet capture features, you can easily and quickly response."
 

Cons

"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."
"Cloud signaling integration with third-party DDoS solution provider. Currently, it supports only its DDoS APS box."
"The implementation should be made easier."
"It could include a lot of enhancements related to AI and automation."
"There is always room for improvement for any product or service. If we can bring in more agility when deploying services, that is definitely a scope which we can work towards."
"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."
"If we want to see live traffic, we can do so, but once an attack that lasts for five minutes is done, the data is no longer there."
"Their RESTful API is still a work-in-progress."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
 

Pricing and Cost Advice

Information not available
"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."
"Pricing is slightly on the higher side."
"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."
"It is an expensive product. I use this product for its different features."
"The pricing of the solution is cheap."
"Arbor is striking a good balance between pricing and what they deliver."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
