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

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

Pros

"The automation capabilities significantly improve response times by allowing us to respond to incidents from a single dashboard rather than navigating multiple dashboards."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"The most valuable feature is the integration capability."
"The flexibility for creating manual workflows stands out."
"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."
"I would give Cortex XSIAM a rating of ten out of ten."
"Its ability to deliver a substantial amount of security intelligence greatly enhances and optimizes our security operations program."
"It's very easy for anyone to work with."
"We have many application systems, and I can set up Fortinet FortiSIEM for users to monitor their systems."
"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."
"Its automated response feature has benefited our customer communication. Analysts feel more confident in providing timely responses."
"The stability is very reliable. It offers very good performance."
"Fortinet FortiSIEM provides good detection against advanced threats."
"These aspects make Fortinet FortiSIEM a valuable choice."
"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."
 

Cons

"The support could be a bit faster."
"There is room for improvement in expanding integrations to include more cybersecurity solutions."
"The standard integrations are very limited, and the integrations available are not listed in the marketplace."
"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."
"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."
"The first impression is that XSIAM would be more expensive than others we tried."
"I am not sure if any improvements are needed right now."
"The solution’s pricing and technical support could be improved."
"Their technical support is horrible. By horrible, I mean a train wreck of a disaster that has fallen off a bridge and caught fire."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"The tool's technical team's response time is too high, and they are not available even when they know that there are many pending issues."
"The biggest thing that could be better is a quicker response to support cases."
"Fortinet FortiSIEM needs to provide better API integrations to users."
"When compared with some competitors, in terms of performance, the CPU and RAM requirements and the capability of coordination with development all need some improvement."
"Its training can be improved. Its price also needs to be improved."
"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."
 

Pricing and Cost Advice

"The product cost could be considered value for money compared to other solutions in the market, though it is quite high."
"Since Palo Alto is trying to get as many new customers as possible, they're offering very competitive pricing."
"The solution comes at a significant cost."
"In terms of pricing, we found Cortex XSIAM to offer a very reasonable and competitive rate."
"The solution is expensive compared to its competitors."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"The price is competitive."
"Pricing is determined based on the customer's budget."
"Fortinet FortiSIEM is cheaper compared to other products."
"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."
"Fortinet FortiSIEM is not an expensive solution."
"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."
"There are additional features that cost more than the standard licensing fees."
