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-driven monitoring has improved real-time threat detection but still needs better automation
I could see some workflows, but I am unable to do automated workflows. For example, some repetitive jobs or repetitive tasks I am doing, but I am trying to have less manual intervention on the front. I am raising some issues that should be resolvable. The SentinelOne team has told me that this can be resolved within a couple of months, but they are saying that it is in future for enhancement and it may take some time. So far, the numbers are great. Regarding disadvantages or areas for improvement, I could say that 35 percent of my manual effort can be detected since I implemented it very recently. I could be able to say my current data talks about only 35 percent, and it may improve further, as I am expecting. But I can only comment based on my alerts and events. The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things. This will take some more time, probably another month. Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well.

Quotes from Members

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

Pros

"The most valuable features of the solution is its integration with other technologies, especially its ability to collect logs from Cisco and Aruba devices along with Fortinet products."
"FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated."
"The tool's most valuable feature stems from the fact that I can see a complete analysis, like all the incidents that have happened, and it detects everything in real-time."
"FortiSIEM provides a single PIN to monitor SOC and NOC, is a nice tool for integration and monitoring, and provides multiple categories for monitoring based on security designations like low, medium, and high."
"The seamless integration with FortiGate is the solution's most valuable aspect."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"FortiSIEM allows you to match IPs with threat intelligence feeds from sources like Kaspersky or Anomali, adding valuable context."
"The event correlation is pretty robust."
"SentinelOne Singularity AI SIEM's AI-powered analytics does affect our SOC's ability to reduce false positives; that is one of the biggest advantages because the manpower that I have is limited."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
"When they face attacks such as ransomware and are dissatisfied with their existing solutions, they switch to SentinelOne Singularity AI SIEM, which is quite good in detecting unknown threats, cleaning the system, and handling ransomware."
 

Cons

"The backup and recovery process for this solution needs improvement. I would like to see a database with more structure in terms of maintenance and ease of use."
"This solution is not very scalable if you have a lot of security events; it's focused more around smaller companies."
"If there is a configuration on the wrong side of the network or there are changes that result in harm to our IT infrastructure, the solution should immediately fix it."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"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."
"There is no proper guide for integration or configuration."
"We need more incidents automatically to protect our network."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"At the moment, I feel the pricing is a little bit on the higher side, but the tool is positioned in a place where risk is very high, and we do not want to take chances, so we are prepared to pay the premium."
"In AI SIEM, the areas that have room for improvement are the parsers for third-party integrated data or for third-party data sources that are not native integrations, which could be made a bit easier."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
"It is quite good, but the only downside is that it is costly."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
 

Pricing and Cost Advice

"The solution is available for both, perpetual and subscription licenses."
"If one is cheap and ten is expensive. I rate the tool's price as an eight out of ten. Compared with Splunk or Oracle, Fortinet is cheap."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"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."
"Fortinet FortiSIEM is cheaper compared to other products."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
