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."
"The correlation rules and the user platform are most valuable."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
"The most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"All in all, the product is a well rounded performer when it comes to combined infrastructure and security monitoring, however in traditional SIEM bake-offs, they need a lot more flavour to make it exciting."
"Fortinet FortiSIEM is highly scalable. I would rate its scalability nine out of ten."
"The Threat Hunting feature provides complete traffic analysis."
"It gives greater visibility via the dashboards into the real-time status of the network and also provides specific alerts and performance monitoring."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"Analytics is the most valuable feature, and the business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"Every feature is good. This is one of the greatest SIEM products on the market."
 

Cons

"They can add behavior analytics and AI or machine learning technology."
"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 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."
"The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"The stability of the product is fairly good. It's likely 70-80% there in terms of stability."
"FortiSIEM could be better integrated with other vendors."
"I would like to see more integration with other platforms."
"Fortinet FortiSIEM needs to provide better API integrations to users."
"The customer service team needs additional experience and knowledge of the solution so the answers they provide are more accurate and helpful."
"The solution's technical support didn't help our company a lot."
 

Pricing and Cost Advice

"Regarding pricing, I'd say it's in the middle range. Pricing is very good compared to others."
"They have changed the pricing policy. Its price is competitive. Its price is less than half of the price of QRadar, LogRhythm, and Splunk."
"The price is competitive."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"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."
"They have a yearly subscription."
"Pricing is determined based on the customer's budget."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"We pay for a license for FortiSIEM. We pay for the license and renewal."
"Fortinet FortiSIEM is cheaper compared to other products."
