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.

AI triage has streamlined real-time alert monitoring and has improved on-call incident response
The best features Panther offers are AI Triage, the ability to comment on our activities, and seamless integration with other communication sources such as PagerDuty, Microsoft Teams, and potentially Slack, showcasing the flexibility we have in using this tool. The most valuable feature for my team is definitely AI Triage, which helps save a lot of time by eliminating the need for manual research regarding patterns that may be repeated, making our work easier and more efficient. Panther has positively impacted my organization as it serves as one of the main sources for triaging real-time incidents. Panther definitely plays a key role in the work that we do. Specific outcomes that show how Panther has helped our organization include saving a lot of time, especially since the AI Triage feature reduces the necessity to reach out to others for clarity, which it occasionally accomplishes on its own. To be honest, it does lack some aspects. For example, if it could access our organizational knowledge, including the Jira database, it might better analyze incidents and determine whether they are false positives or not by using more contextual data.

Quotes from Members

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

Pros

"Fortinet FortiSIEM has its own validated and authentic IP database that marks malicious IP attacks against the firewall and generates an alert for the same."
"The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install."
"To add workers and even collectors is pretty easy."
"Easy alert setup which enables different alerts in different categories."
"I like FortiSIEM because it integrates natively with our other Fortinet solutions and the Fortinet Fabric, but it also integrates with Cisco, Palo Alto and other security fabrics."
"FortiSIEM helped us discover all the threats at the time that were attacking the IT services of the company. We now have multiple-level authentication."
"The most valuable feature of Fortinet FortiSIEM is the correlation of many events."
"The network monitoring is one of the most valuable aspects of the solution."
"Panther positively impacts my organization as it is the first point of response for any incident, giving a reviewer full clarity about what is happening, how it is happening, and where it is happening."
"We have seen a return on investment measured primarily through SOC efficiency and productivity improvements, with teams observing a twenty to thirty-five percent improvement in investigation efficiency depending on the environment and product maturity."
"I find Panther's detection capabilities and integrations to be highly valuable."
"The AI Triage feature saves a considerable amount of time, and if it were to incorporate organizational knowledge, it could provide finer-tuned results."
 

Cons

"The biggest thing that could be better is a quicker response to support cases."
"There is no proper guide for integration or configuration. They need to improve the documentation library."
"We need more incidents automatically to protect our network."
"The log collection and configuration management are not great."
"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."
"We expect the latest patch from Fortinet FortiSIEM to give the ability to work with signature files."
"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."
"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."
"The user experience could be improved because whenever I want to investigate the data, too much data is shown in the UI."
"The solution could be improved by providing more built-in integrations, which would reduce the need for me to build them myself."
"Regarding Panther's accuracy and reliability of output, I would rate it at 70 percent since, at times, it identifies findings as valid when they may actually be false positives, which we have experienced in a few cases."
 

Pricing and Cost Advice

"We pay for a license for FortiSIEM. We pay for the license and renewal."
"There are additional features that cost more than the standard licensing fees."
"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."
"Please be cheaper and more simplified."
"There is a need to make yearly payments towards the licensing charges attached to the product. The free version license of the product is available for two months."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"Fortinet's products are not expensive, it is less than the competition."
"Fortinet FortiSIEM is cheaper compared to other products."
