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 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."

"Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had."

"It is used as an alerting platform."

"The advanced agents used to collect logs have been most valuable. We have also made use of the advanced intelligence this solution offers."

"It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security."

"The event correlation is pretty robust. The GUI is pretty good."

"FortiSIEM is a great tool for making security processes transparent."

"I like the various options, including the option for CMDB and the easier access to create rules, playbooks, or use cases. It's also easier to use for creating dashboards and reports."

"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."

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."

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

"The dashboards need to be improved. It gives you so much detail, but sometimes too much detail, especially to an executive, it's too much."

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

"Performance could be enhanced, but I do not wish to elaborate on needed improvements."

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

"Their technical support is horrible. By horrible, I mean a train wreck of a disaster that has fallen off a bridge and caught fire."

"The backup and recovery process for this solution needs improvement."

"They could work on their documentation. If there's anything about the solution that needs improvement, it's that. For example, documentation already is on a very high level but specifically on the CLI there are tons of features which can be fine-tuned and thousands of commands are very difficult to document. If they could make this easier, it would improve the overall solution."

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."

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

"Pricing is determined based on the customer's budget."

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

"Fortinet FortiSIEM is cheaper compared to other products."

"They have a yearly subscription."

"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."

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