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.

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

"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."
"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 most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"The most valuable feature is the anomaly-reporting alarms."
"This is a very stable product - we have never had a crash with it."
"FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated."
"The most valuable features of Fortinet FortiSIEM are the SD-WAN, Global LAN, and application controls."
"The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install."
"Analytics is the most valuable feature, and the business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"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."
 

Cons

"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."
"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."
"When our team tried configuring logs for Microsoft SQL, it did not work."
"We need more incidents automatically to protect our network."
"Does not have load-sharing or high-availability, and these are important things to implement. I can do the same things in another way, but not naturally having these features makes it complicated."
"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 product does not have Security Orchestration and Automation Response, I would recommend adding this feature."
"The patch management on the software needs to be better."
"FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware."
"I would like to see easier implementation in the future."
 

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."
"Fortinet's products are not expensive, it is less than the competition."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"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."
"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."
"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 solution is available for both, perpetual and subscription licenses."
"The price is competitive."
"Pricing is determined based on the customer's budget."
