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.

Real-time monitoring and analytics are very easy and fast and very easy to use
The alerting and real-time analytics helped the security team. They are using a Hadoop database, so real-time monitoring and analytics are very easy and fast. Queries return results quickly and in very small time. It has full automation and automated SIEM responses. We are currently only testing Logsign, but in a few months, we plan to integrate our servers, routers, firewalls, and endpoints into our company's Logsign instance. Then, we can manage everything using Logsign.

Quotes from Members

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

Pros

"Easy alert setup which enables different alerts in different categories."
"The product is quite well-organized. The GUI makes it easy to navigate."
"We only evaluated this solution and loved the capabilities that it offers."
"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. That was handled flawlessly."
"FortiSIEM allows you to match IPs with threat intelligence feeds from sources like Kaspersky or Anomali, adding valuable context."
"We have found the most important features in Fortinet FortiSIEM to be the correlation, file utility check, latest file, and hash changes. These features are important for us."
"FortiSIEM's stability is quite good."
"AccelOps gives us a greater visibility into potential data/network breach attempts with the monitoring and alerting capabilities."
"It has full automation and automated SIEM responses."
"Logsign provides sample logs within the product, allowing users to see how logs will appear before integration, which is a valuable feature for testing and understanding log formats."
"The most valuable features of Logsign SIEM are its cloud capabilities, alerting functionality, integration with Elastic Search, and configuration options."
 

Cons

"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 initial setup with Fortinet FortiSIEM Accelops was not easy. We had faced a few problems, but I think Fortinet should give more training courses for their resellers."
"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."
"The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."
"I would like to see more integration with other platforms."
"Network detection and response is a separate product."
"Their product support, in general, is not that great. When you log a call, you don't get instant replies or if there is a bug they take ages to fix it and they ask you to hold."
"Fortinet FortiSIEM needs to provide better API integrations to users."
"Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively."
"I hope they address the pricing model for Logsign Next-Gen SIEM, especially regarding regional variations. The pricing should not differ based on the country of operation as it can lead to dissatisfaction among customers. A fixed pricing structure would be more favorable for us. I would also suggest enhancing the GUI interface and adding features similar to xFi Exchange from IBM Pure. This would streamline operations and save time for analysts."
"AI and machine learning need to be developed. If they develop those features, I think everything will be fine."
 

Pricing and Cost Advice

"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"Please be cheaper and more simplified."
"Fortinet FortiSIEM is cheaper compared to other products."
"This is probably more on the lower cost end of the spectrum compared to competing products. Fortinet's license model is based on events per second, which makes sense, but that's not typical. It makes it very hard to calculate what your costs are going to be as you scale the platform because some log sources, such as firewall logs, are very noisy, and there are lots and lots of events per second, but some of them are not. So, it becomes a bit of a science experiment trying to guess what your costs are going to be as you scale the solution. This is where other competing products perhaps have a more straightforward license model."
"The solution is available for both, perpetual and subscription licenses."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"Compared to other SIEMs, it has low pricing."
