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

"To add workers and even collectors is pretty easy."

"With the help of FortiSIEM we have improved the cybersecurity posture of our clients and ours, and through the early detection of threats, it allows us to follow up on each security incident and easily communicate to asset managers about related security events, reducing remediation time."

"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 most valuable features of Fortinet FortiSIEM are the SD-WAN, Global LAN, and application controls."

"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."

"Fortinet FortiSIEM has helped our organization by providing us with business monitoring."

"Fortinet FortiSIEM needs to provide better API integrations to users."

"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."

"The most valuable feature of this product is innovation, where the research and upgrading of technology never ends."

"IBM Watson for Cyber Security is very stable."

Cons

"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."

"The reporting feature is not very attractive for the upper management and I am not able to perform complex/nested queries."

"It lacks a "wizard" that shows a particular user's activity or particular circumstance."

"The backup and recovery process for this solution needs improvement."

"They could work on their documentation. If there's anything about the solution that needs improvement, it's that. 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. If they could make this easier, it would improve the overall solution."

"They should enhance the solution's AI capabilities, including XDR and EDR."

"I would like to see more integration with other platforms."

"The UI could improve in Fortinet FortiSIEM. Humans view the UI frequently for data and if it was more visually pleasing it would be beneficial."

More Fortinet FortiSIEM cons

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

"They need to continue to build the AI capabilities."

"The dashboard could improve in IBM Watson for Cyber Security."

"In the future, I would like to see threat intelligence included."

"They have a yearly subscription."

"Pricing is determined based on the customer's budget."

"The tool is really expensive. For what the tool does for our team, the price is fair."

"Fortinet FortiSIEM is not an expensive solution."

"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."

"The price is competitive."

"Manageable, however would be better as pay as you go versus CapEX."

More Fortinet FortiSIEM pricing and cost advice
