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.

Advanced AI-driven monitoring has strengthened investigations and now prioritizes critical threats
I would not say there is anything that could be better in SentinelOne Singularity AI SIEM; I think we have seen something unique in the product. This product has the potential to add more SOC functionality on top of its SIEM, which can automate a few more things because I have the information there. I need to do what I would call security agents or agentic AI to be built on top; it can take care of a lot more analysis and actions. Maybe licensing cost can also be looked at and reduced. We are still to see the automated feature work a little bit more; we are not really using it to the full extent.

Quotes from Members

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

Pros

"This is a very stable product - we have never had a crash with it."
"It's a very nice solution to work with."
"The network monitoring is one of the most valuable aspects of the solution."
"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."
"Its automated response feature has benefited our customer communication. Analysts feel more confident in providing timely responses."
"It's easy to manage. There's a web interface and a command line, depending on what the user is comfortable with. There's a large knowledge base available, and the support is timely."
"The event correlation is pretty robust."
"The Threat Hunting feature provides complete traffic analysis."
"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."
"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."
"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."
"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
 

Cons

"The initial setup with Fortinet FortiSIEM Accelops was not easy. We had faced a few problems, but I think Fortinet should give more training courses for their resellers."
"For example, the design is bad because you have one supervisor on one machine and you handle everything off this machine supervisor."
"I would like to see more integration with other platforms."
"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."
"Fortinet FortiSIEM could improve to extend to several locations or sites."
"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 built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
"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."
"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."
"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."
 

Pricing and Cost Advice

"They have a yearly subscription."
"There are additional features that cost more than the standard licensing fees."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"Manageable, however would be better as pay as you go versus CapEX."
"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."
"Please be cheaper and more simplified."
"Pricing is determined based on the customer's budget."
"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."
