Comprehensive monitoring boosts security, yet incident management features need expansion
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.

Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience
There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Quotes from Members

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

Pros

"It gives greater visibility via the dashboards into the real-time status of the network and also provides specific alerts and performance monitoring."
"We only evaluated this solution and loved the capabilities that it offers."
"Fortinet FortiSIEM combines the SOC and NOC into a single solution with a single pane of glass."
"The most valuable features of the solution is its integration with other technologies, especially its ability to collect logs from Cisco and Aruba devices along with Fortinet products."
"The most valuable feature is the dashboard. CMDB database collects data from a lot of pre-configured devices."
"FortiSIEM helped us discover all the threats at the time that were attacking the IT services of the company. We now have multiple-level authentication."
"FortiSIEM provides a single PIN to monitor SOC and NOC. It's a nice tool for integration and monitoring. It provides multiple categories for monitoring based on security designations like low, medium, and high."
"The event correlation is pretty robust. The GUI is pretty good."
"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."
"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."
"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."
"Go take a look at it. It's a great product and has great capabilities."
"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."
"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."
"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."
"Enables us to go back in time to capture an issue and analyze it for a solution, and this after the fact analysis is key to overcoming the bump in the night issues."
 

Cons

"The initial setup is not simple. We are having some issues with the agent installation, it is requiring several reboots."
"FortiSIEM is not a market leader in the SIEM space."
"Improvements include making it easier for users to create their normalizers. Fortinet FortiSIEM uses XML for normalizing and parsing, which can be tedious and time-consuming. A simpler way of using regex could be helpful."
"Its training can be improved. Its price also needs to be improved."
"The initial setup is complex. They need to make it easier in terms of implementation."
"Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR."
"It's difficult to integrate unsupported devices with FortiSIEM compared to QRadar. It's easier to integrate and develop processes in QRadar. It's harder to develop a custom process in FortiSIEM."
"The dashboards need to be improved. It gives you so much detail, but sometimes too much detail, especially to an executive, it's too much."
"The Observer Console UI is consistent and stable, but could use some updating to be more modern."
"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."
"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."
"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."
"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."
"I would like to have more than 4TB of storage available in the portable version of this solution."
"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."
