Featured Reviews

Zuhair Hasan - PeerSpot reviewer
Manager, Information Technology Security at Nesma
Has good integration capability and provides information and events but improvement is needed in information retrieval speed
The best features are the comprehensive event collection and analysis. Once set up properly, we receive all events and information. The team analyzes our data and presents incidents to us. We can communicate with their team to escalate and resolve incidents. It has a feature we use to search for information about our environment and past incidents. This is very valuable. The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets.

Network Engineer at Ogma Consulting
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.

Quotes from Members

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

Pros

"The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
"The correlation rules and the user platform are most valuable."
"Fortinet FortiSIEM's most valuable feature is the simplicity in handling multi-tenancy and the ability to switch between different clients at the same time. That was handled flawlessly."
"Fortinet FortiSIEM has its own validated and authentic IP database that marks malicious IP attacks against the firewall and generates an alert for the same."
"We like the integration of all of these Fortinet platforms together. Everything is integrated well, and we are able to sell that as a service to our customers."
"The solution is easy to use and user-friendly."
"Analytics is the most valuable feature, and the business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"The beautiful thing about Fortinet is that they have integrated many, many solutions."
"We have many application systems, and I can set up Fortinet FortiSIEM for users to monitor their systems."
"The primary thing I use it for is monitoring IPS because we have 12 or 14 Cisco IPS devices, and the Cisco solution for monitoring that many IPS devices is hokey at best, aside from it being expensive."
 

Cons

"The main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."
"They can add behavior analytics and AI or machine learning technology."
"They can add behavior analytics and AI or machine learning technology. They also improve their correlation engine. In addition to collecting logs from devices, they can collect the traffic and then correlate these logs and the traffic information."
"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"
"The policy editing should be easier. Right now, it's too hard."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"The patch management on the software needs to be better."
"Ease-of-use for end users that do not spend every day in the product. Also, the presentation of historical and trending data in dashboards needs to be improved immensely."
"I would like to see more integration with other platforms."
"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."
"Patching is not great - we're not getting the support we'd expect."
 

Pricing and Cost Advice

"They have changed the pricing policy. Its price is competitive. Its price is less than half of the price of QRadar, LogRhythm, and Splunk."
"Regarding pricing, I'd say it's in the middle range. Pricing is very good compared to others."
"They have a yearly subscription."
"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."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"The price is competitive."
"Pricing is determined based on the customer's budget."
"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."
