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

"Analytics. It can provide log information from the device."
"The solution is easy to use and user-friendly."
"It's a very nice solution to work with."
"It gives us the opportunity to generate notifications based upon rules that get triggered, and the rules could be specific to PCI, HIPAA, GIBA, NIST, and so forth."
"Technical support is helpful."
"AccelOps can handle a lot of data and it's just so important to true monitoring."
"FortiSIEM's best features are the dashboards and customization."
"FortiSIEM sends an email or SMS notifications to admins when there are significant incidents. It's a highly efficient way of responding to incidents."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
"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."
"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

"Customer support service could be better."
"FortiSIEM could be better integrated with other vendors."
"Their product support, in general, is not that great. The product support is in the same ecosystem. Their support is improving but it's not that great.vvv"
"It's difficult to integrate unsupported devices with FortiSIEM compared to QRadar."
"As we're an SMB, I would like to see different licensing options and the solution is priced out of the reach of some small businesses."
"Issues that could have been resolved in 30-60 minutes sometimes took months, but they have improved."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"When our team tried configuring logs for Microsoft SQL, it did not work."
"It is quite good, but the only downside is that it is costly."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
"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."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
 

Pricing and Cost Advice

"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."
"Manageable, however would be better as pay as you go versus CapEX."
"The price is competitive."
"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."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"The solution is available for both, perpetual and subscription licenses."
"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."
"Fortinet FortiSIEM is not an expensive solution."
