Zuhair Hasan

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

"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 valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."

"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."

"The primary valuable feature is that it has replaced a whole lot of other products with one platform."

"Fortinet FortiSIEM is less costly than other products and is available 24/7."

"FortiSIEM allows you to match IPs with threat intelligence feeds from sources like Kaspersky or Anomali, adding valuable context."

"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."

"Easy alert setup which enables different alerts in different categories."

"The most valuable feature of Fortinet FortiSIEM is the correlation of many events."

More Fortinet FortiSIEM pros

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."

"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 an alert triggers in Fortinet FortiSIEM, the layout or format can feel limited"

"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."

"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."

"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"

"Patching is not great - we're not getting the support we'd expect."

"When compared with some competitors, in terms of performance, the CPU and RAM requirements and the capability of coordination with development all need some improvement."

"The log collection and configuration management are not great."

"FortiSIEM is not a market leader in the SIEM space."

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."

"There are additional features that cost more than the standard licensing fees."

"Fortinet FortiSIEM is cheaper compared to other products."

"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."

"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."

"We pay for a license for FortiSIEM. We pay for the license and renewal."

"The tool is really expensive. For what the tool does for our team, the price is fair."

"They have a yearly subscription."
