Oliver Jackson - PeerSpot reviewer
Systems monitoring enhanced by firewall and intrusion detection features
My primary use case for Fortinet FortiSIEM is systems monitoring and alerting. I use it for standard functions like log monitoring, incident detection, and notification.  My customers are mostly medium-sized enterprises ranging from engineering companies, mining companies, independent schools, and…
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"To add workers and even collectors is pretty easy."
"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."
"The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."
"It works well with medium to large-scale enterprises."
"The most valuable feature of Fortinet FortiSIEM is the user and entity behave as analytics(UEBA). This feature mixes your data and provides useful information based on the behavior of the targeted."
"The stability is very reliable. It offers very good performance."
"Real-time monitoring makes life quite easy for me."
"FortiSIEM sends an email or SMS notifications to admins when there are significant incidents. It's a highly efficient way of responding to incidents."
"The most valuable features include the incident review and Dashboard Studio."
"We can quickly search for almost anything across many log sources in seconds."
"One key advantage of Splunk over competitors like IBM QRadar is its superior device integration capabilities."
"Splunk is a user-friendly solution."
"The most valuable features in Splunk Enterprise Security are the cluster capabilities."
"I really like the user interface and how it works."
"Its usability is the best part. It is easy for our developers to use if they want to search their logs, etc."
"There are lots of free learning materials on their website."
 

Cons

"It's difficult to integrate unsupported devices with FortiSIEM compared to QRadar. It's easier to integrate and develop processes in QRadar. It's harder to develop a custom process in FortiSIEM."
"If there is a configuration on the wrong side of the network or there are changes that result in harm to our IT infrastructure, the solution should immediately fix it."
"The interface needs some improvements because it's a bit cumbersome when you're trying to view items. It takes some time to get used to. Additionally, sometimes the scrolling does not work."
"The support of the product changed recently, and I don't think it's for the better. They should work to improve the support they offer to clients."
"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."
"When our team tried configuring logs for Microsoft SQL, it did not work."
"I would like to see more integration with other platforms."
"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."
"Custom visualizations are real hard. While the default visualizations are good, creating enhanced visualizations are complex."
"Over time I will have more requirements and I can foresee the solution could improve the search algorithm to run and output the data faster."
"Having analysts put their notes directly within the investigation feature in the incident review would be beneficial."
"The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex."
"The price of the solution could be cheaper."
"I do not like the pricing model. It is expensive."
"The product could be cheaper."
"The initial setup is complex, but this is necessary. We needed to take into consideration how to direct log files from thousands of machines to Splunk, and how to ingest those files."
 

Pricing and Cost Advice

"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."

"Fortinet FortiSIEM is cheaper compared to other products."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."

"Fortinet's products are not expensive, it is less than the competition."
"It's a yearly subscription."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"The licensing is good, but the pricing absolutely needs some work. It is very high."
"Its pricing model can be improved."
"Splunk Enterprise Security is expensive."
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
