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.

Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.

Quotes from Members

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

Pros

"We like the integration of all of these Fortinet platforms together. Everything is integrated well, and we are able to sell that as a service to our customers."
"FortiSIEM gives us a lot of valuable events and details by using a unified event-based framework to analyze all data including logs, performance monitoring data and provides a broad range of metrics."
"Analytics is the most valuable feature. The business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"The best features are the dashboard and the integration between the Fortinet products, and if you use them together with FortiSOAR and FortiAnalyzer, it's better than Splunk."
"Fortinet FortiSIEM's most valuable feature is the simplicity in handling multi-tenancy and the ability to switch between different clients at the same time."
"The most valuable feature is the differentiator, which has a combination of not only the SOC which covers the security operations aspect, but it also includes NOC capabilities."
"The tool's most valuable feature stems from the fact that I can see a complete analysis, like all the incidents that have happened, and it detects everything in real-time."
"The most valuable feature is the anomaly-reporting alarms."
"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
 

Cons

"Fortinet FortiSIEM could improve by having a signature update."
"FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware."
"It's difficult to integrate unsupported devices with FortiSIEM compared to QRadar."
"The solution's interface could be modernized and improved."
"They need to integrate better with Cisco and Palo Alto."
"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."
"We expect the latest patch from Fortinet FortiSIEM to give the ability to work with signature files."
"They could work on their documentation. For example, documentation already is on a very high level but specifically on the CLI there are tons of features which can be fine-tuned and thousands of commands are very difficult to document."
"Graylog Security needs to incorporate security scorecards."
 

Pricing and Cost Advice

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"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."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"The price is competitive."
"Fortinet's products are not expensive, it is less than the competition."
"They have a yearly subscription."
"There are additional features that cost more than the standard licensing fees."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"I rate the tool's pricing a one out of ten."
