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.

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 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 solution's interface could be modernized and improved."

"Fortinet FortiSIEM could improve by having a signature update."

"The policy editing should be easier. Right now, it's too hard."

"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."

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

"They need to integrate better with Cisco and Palo Alto."

"There could be more AI features included in the product."

"I would like to see more integration with other platforms."

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."

"Fortinet FortiSIEM is not an expensive solution."

"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."

"Manageable, however would be better as pay as you go versus CapEX."

"Fortinet FortiSIEM is cheaper compared to other products."

"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."

"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."

"The price of Fortinet FortiSIEM was reasonable compared to other solutions."

"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."
