Featured Reviews

Forrest Stevens - PeerSpot reviewer
A robust security operation that ensures achieving automation, stability, and scalability
There is room for improvement in some areas, and I would highlight three key aspects. Firstly, the Attack Surface Management (ASM) module could benefit from more contextual depth. Currently, it tends to provide a broad overview without enriched context, and there's room for enhancement in this regard. Secondly, further integration capabilities with various other software products that can seamlessly tie into Cortex XSIAM would be advantageous. This would enhance its versatility and interoperability within a broader ecosystem. Regarding performance, there's potential for optimization. When multiple tabs are open in Cortex XSIAM, it can experience slowdowns, leading to longer load times for web pages. It's worth noting that this isn't a severe issue, and it doesn't entail waiting for extended periods, but there is room for improvement in terms of performance optimization.

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

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

Pros

"The flexibility for creating manual workflows stands out."
"The most valuable features of Cortex XSIAM are the machine learning used to identify threats, the complexity of the environment of products, and efficiency."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"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."
"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."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"I would give Cortex XSIAM a rating of ten out of ten."
"The automation capabilities significantly improve response times by allowing us to respond to incidents from a single dashboard rather than navigating multiple dashboards."
"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."
"The solution is easy to use and user-friendly."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"The seamless integration with FortiGate is the solution's most valuable aspect."
"The event correlation is pretty robust. The GUI is pretty good."
"Technical support is helpful."
"The product is quite well-organized. The GUI makes it easy to navigate."
"I like the various options, including the option for CMDB and the easier access to create rules, playbooks, or use cases. It's also easier to use for creating dashboards and reports."
 

Cons

"The standard integrations are very limited, and the integrations available are not listed in the marketplace. Obtaining validation for integrations from Palo Alto takes around eight months, which is quite long."
"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."
"There is room for improvement in expanding integrations to include more cybersecurity solutions."
"Further integration capabilities with various other software products that can seamlessly tie into Cortex XSIAM would be advantageous."
"The platform isn't very developer-friendly and it should provide more flexibility and ease."
"The standard integrations are very limited, and the integrations available are not listed in the marketplace."
"The support could be a bit faster."
"The first impression is that XSIAM would be more expensive than others we tried."
"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."
"Does not have load-sharing or high-availability, and these are important things to implement. I can do the same things in another way, but not naturally having these features makes it complicated."
"Fortinet FortiSIEM is a little out of sight and needs more marketing efforts to be popular in the market."
"The support of the product changed recently, and I don't think it's for the better. They should work to improve the support they offer to clients."
"I would like to see easier implementation in the future."
"The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."
"The deployment of the platform took some time to set up and configure."
"The stability of the product is an area of concern where improvements are required."
 

Pricing and Cost Advice

"In terms of pricing, we found Cortex XSIAM to offer a very reasonable and competitive rate."
"The product cost could be considered value for money compared to other solutions in the market, though it is quite high."
"The solution comes at a significant cost."
"Since Palo Alto is trying to get as many new customers as possible, they're offering very competitive pricing."
"The solution is expensive compared to its competitors."
"The solution is available for both, perpetual and subscription licenses."
"Manageable, however would be better as pay as you go versus CapEX."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"Fortinet FortiSIEM is cheaper compared to other products."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
