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.

Quotes from Members

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

Pros

"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."
"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 CMDB and the device discovery features are most valuable."
"It's easy to manage. There's a web interface and a command line, depending on what the user is comfortable with. There's a large knowledge base available, and the support is timely."
"It's very easy for anyone to work with."
"Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had."
"The primary valuable feature is that it has replaced a whole lot of other products with one platform."
"Fortinet support is very fast, and if I need to ask something, I'll get a response within a couple of hours."
"IBM Watson for Cyber Security is very stable."

Cons

"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."
"The solution needs to do a better job with third party integration; most of the AWS environment products do not have the capability to integrate."
"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."
"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."
"The interface needs some improvements because it's a bit cumbersome when you're trying to view items."
"Fortinet FortiSIEM could improve by having better integration and extensions. This would benefit by allowing us to give more rules."
"The support of the product changed recently, and I don't think it's for the better."
"It would be good if the solution offered even more configuration options, especially in relation to the VPN so that it continues to be a very flexible option."
"In the future, I would like to see threat intelligence included."
"They need to continue to build the AI capabilities."

"This is an expensive product, so making it more cost-effective would be an improvement."
