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.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Technical support is helpful."
"If you don't have a dedicated team to handle your logs, don't have a big budget, and want a solution to correlate and collect logs from many vendors, Fortinet FortiSIEM is an excellent choice."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"The most valuable features of the solution is its integration with other technologies, especially its ability to collect logs from Cisco and Aruba devices along with Fortinet products."
"It's very easy for anyone to work with."
"Fortinet FortiSIEM is easy to use."
"These aspects make Fortinet FortiSIEM a valuable choice."
"Scalability is very good."
"The detection of ransomware in the internal network has benefited my organization."
"The most valuable feature is the correlation, as it can report in real-time and monitor the management."
"Technically speaking, this is a good product."
"Since the solution has been under way we have seen a large decrease of threats and proactive reactions to incidents."
"Their customer service is excellent, one of the best."
"The most valuable feature is the ability to write rules and triggers for network communication and then being able to investigate based on that, where you can see the payload and deconstruct the packets."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"Overall, I feel that the product is very good and my biggest complaint is about their support."
 

Cons

"Fortinet FortiSIEM could improve by having a signature update."
"The performance can be improved. Sometimes it takes a long time to fetch data."
"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."
"FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware."
"The solution's technical support didn't help our company a lot."
"There is no proper guide for integration or configuration. They need to improve the documentation library."
"This solution is not very scalable if you have a lot of security events; it's focused more around smaller companies."
"I would like to see more integration with other platforms."
"The initial setup is complex. There are other solutions that are easier to implement."
"I cannot say that the solution was stable because it tended to crash."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"The solution should have more integration capabilities with different platforms."
"RSA NetWitness Logs and Packets is far behind the competition."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"The initial setup is complex. It requires some knowledge in order to set it up."
 

Pricing and Cost Advice

"There are additional features that cost more than the standard licensing fees."
"Please be cheaper and more simplified."
"Manageable, however would be better as pay as you go versus CapEX."
"They have a yearly subscription."
"We pay for a license for FortiSIEM. We pay for the license and renewal."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"Pricing is determined based on the customer's budget."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"Compared to the competition, the is price is not that high."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
