Featured Reviews

AKASH MAJUMDER - PeerSpot reviewer
Incident response times have significantly reduced with efficient device integration and log parsing capabilities
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports. Additionally, a future update request is to enable tagging of endpoints in groups, similar to a feature available in Cortex XDR. The AI analytics need fine-tuning because some use cases are not working from my side.
Oliver Jackson - PeerSpot reviewer
Systems monitoring enhanced by firewall and intrusion detection features
My primary use case for Fortinet FortiSIEM is systems monitoring and alerting. I use it for standard functions like log monitoring, incident detection, and notification.  My customers are mostly medium-sized enterprises ranging from engineering companies, mining companies, independent schools, and…

Quotes from Members

Pros

"Cortex XSIAM enhances our ability to apply endpoint protection policies, implement restrictions, conduct scans, and engage in sandboxing."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"It does a better job of identifying anomalies that are more likely to be incidents of compromise without as many false positives or false negatives."
"It operates on a single, extensive database which enables it to excel in detecting threats and anomalies across the network and endpoints, delivering a highly effective and comprehensive security solution."
"The automation capabilities significantly improve response times by allowing us to respond to incidents from a single dashboard rather than navigating multiple dashboards."
"The flexibility for creating manual workflows stands out."
"Since implementing Cortex XSIAM, incident response times have been significantly reduced by approximately twenty percent."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"This solution offers extensive customization options, making it possible to adapt it precisely to their requirements."
"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 most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"The most valuable feature is auto-discovery. When you send logs from any device to port 514, it helps register those devices automatically."
"FortiSIEM provides a single PIN to monitor SOC and NOC. It's a nice tool for integration and monitoring. It provides multiple categories for monitoring based on security designations like low, medium, and high."
"Fortinet FortiSIEM provides good detection against advanced threats."
"The stability is very reliable. It offers very good performance."
 

Cons

"Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports."
"There is room for improvement in expanding integrations to include more cybersecurity solutions."
"The solution’s pricing and technical support could be improved."
"Cortex XSIAM is pretty expensive, and the licensing process is not very comfortable compared to CrowdStrike."
"The support could be a bit faster."
"Cortex could improve the detection and online resolution of security vulnerabilities."
"I would rate the overall stability a six or seven, as we have only used it for a few months and need a year of experience to provide a full assessment."
"I am not sure if any improvements are needed right now."
"They should enhance the solution's AI capabilities, including XDR and EDR."
"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 biggest thing that could be better is a quicker response to support cases."
"Improvements include making it easier for users to create their normalizers. Fortinet FortiSIEM uses XML for normalizing and parsing, which can be tedious and time-consuming. A simpler way of using regex could be helpful."
"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."
"The solution's technical support didn't help our company a lot."
"Not very good on non-API features, lacks that functionality."
"Fortinet FortiSIEM could improve to extend to several locations or sites."
 

Pricing and Cost Advice

"Since Palo Alto is trying to get as many new customers as possible, they're offering very competitive pricing."
"In terms of pricing, we found Cortex XSIAM to offer a very reasonable and competitive rate."
"The solution comes at a significant cost."
"The solution is expensive compared to its competitors."
"The product cost could be considered value for money compared to other solutions in the market, though it is quite high."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"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."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"Pricing is determined based on the customer's budget."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"There are additional features that cost more than the standard licensing fees."
"The solution is available for both, perpetual and subscription licenses."
