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

"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."
"Scalability is very good."
"The most valuable features of Fortinet FortiSIEM are the SD-WAN, Global LAN, and application controls."
"Fortinet FortiSIEM has helped our organization by providing us with business monitoring."
"Fortinet FortiSIEM provides good detection against advanced threats."
"I like the various options, including the option for CMDB and the easier access to create rules, playbooks, or use cases, and it's also easier to use for creating dashboards and reports."
"Both the collecting logs and duo correlation are valuable features for us."
"The primary valuable feature is that it has replaced a whole lot of other products with one platform."
"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
 

Cons

"Their product support, in general, is not that great. The product support is in the same ecosystem. Their support is improving but it's not that great.vvv"
"The initial setup is complex. They need to make it easier in terms of implementation."
"The tool's technical team's response time is too high, and they are not available even when they know that there are many pending issues."
"Ease-of-use for end users that do not spend every day in the product. Also, the presentation of historical and trending data in dashboards needs to be improved immensely."
"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."
"FortiSIEM needs to expand its integration with third-party vendors. I don't know if Forcepoint has been added, but there were limited resources for integrating Forcepoint solutions when we implemented FortiSIEM. It integrates well with other Fortinet products and solutions from established cybersecurity companies like Palo Alto but doesn't integrate with some of the newer vendors."
"With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk."
"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."
"Graylog Security needs to incorporate security scorecards."
 

Pricing and Cost Advice

"The solution is available for both, perpetual and subscription licenses."
"We pay for a license for FortiSIEM. We pay for the license and renewal."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"Please be cheaper and more simplified."
"Fortinet FortiSIEM is cheaper compared to other products."
"Fortinet's products are not expensive, it is less than the competition."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"I rate the tool's pricing a one out of ten."
