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

"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."
"FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated."
"Analytics. It can provide log information from the device. With log information, I can see if there is a threat"
"Fortinet FortiSIEM has helped our organization by providing us with business monitoring."
"FortiSIEM's best features are the dashboards and customization."
"It detects new technologies, vulnerabilities, and emerging threats on the internet."
"We only evaluated this solution and loved the capabilities that it offers."
"It gives greater visibility via the dashboards into the real-time status of the network and also provides specific alerts and performance monitoring."
"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"
"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."
"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."
"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."
"Go take a look at it. It's a great product and has great capabilities."
"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."
 

Cons

"The backup and recovery process for this solution needs improvement. I would like to see a database with more structure in terms of maintenance and ease of use."
"The dashboards need to be improved."
"As we're an SMB, I would like to see different licensing options and the solution is priced out of the reach of some small businesses."
"The initial setup is not simple. We are having some issues with the agent installation, it is requiring several reboots."
"The interface needs some improvements because it's a bit cumbersome when you're trying to view items. It takes some time to get used to. Additionally, sometimes the scrolling does not work."
"The stability of the product is an area of concern where improvements are required."
"One of the things that actually opened a ticket about (and they couldn’t help me) is when traffic is leaving our network, it’ll only report the source."
"This solution is not very scalable if you have a lot of security events; it's focused more around smaller companies."
"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."
"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."
"I would like to have more than 4TB of storage available in the portable version of this solution."
"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."
"The Observer Console UI is consistent and stable, but could use some updating to be more modern."
"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."
"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."
 

Pricing and Cost Advice

"There are additional features that cost more than the standard licensing fees."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"Manageable, however would be better as pay as you go versus CapEX."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"Pricing is determined based on the customer's budget."
"If one is cheap and ten is expensive. I rate the tool's price as an eight out of ten. Compared with Splunk or Oracle, Fortinet is cheap."
"Its price can be better. We are Fortinet partners, so we can get discounts, but its price can be an issue at the beginning for others. There is a licensing scheme for every case. There are three licensing schemes that we can choose from."
"It's quite expensive."
"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."
