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

"The most valuable feature of Fortinet FortiSIEM is the correlation of many events."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"It works well with medium to large-scale enterprises."
"We have many application systems, and I can set up Fortinet FortiSIEM for users to monitor their systems."
"The most valuable feature is the dashboard. CMDB database collects data from a lot of pre-configured devices."
"The CMDB and the device discovery features are most valuable."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"The tool's most valuable feature stems from the fact that I can see a complete analysis, like all the incidents that have happened, and it detects everything in real-time."
"We evaluated several solutions and selected Splunk due to the functionality and cost."
"It is very simple to tweak or write a small piece of glue code to go ahead and create a new dashboard for a business unit to make near real-time decisions to focus more on other geographies when launching the product."
"The scalability of the solution is amazing because it can collect a lot of data and you can have your own structure to monitor this data."
"The solution allows easy gathering and ingestion of the data."
"Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize."
"The best part of Splunk Enterprise Security is its customizable settings."
"We did not encounter any issues with scalability. It is almost seamless to add new index (storage) or search (used to analyze the data) nodes to the cluster."
"Splunk stands out for its extensive application integrations."
 

Cons

"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."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"The tool's technical team's response time is too high, and they are not available even when they know that there are many pending issues."
"FortiSIEM needs to expand its integration with third-party vendors. I don't know if Forcepoint has been added, but there were limited resources for integrating Forcepoint solutions when we implemented FortiSIEM. It integrates well with other Fortinet products and solutions from established cybersecurity companies like Palo Alto but doesn't integrate with some of the newer vendors."
"When an alert triggers in Fortinet FortiSIEM, the layout or format can feel limited"
"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 biggest thing that could be better is a quicker response to support cases."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"Technical support needs to be more responsive."
"It would be good if the solution had some kind of copilot to automate or help write correlation searches."
"Queries are not always as easy or straightforward as they might be, so it can be difficult to figure out what you need to look for."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
"When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."
"Splunk isn't appropriate for smaller companies. It's too expensive."
"It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
 

Pricing and Cost Advice

"Manageable, however would be better as pay as you go versus CapEX."
"The solution is available for both, perpetual and subscription licenses."
"The price is competitive."
"Fortinet FortiSIEM is not an expensive solution."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"Fortinet's products are not expensive, it is less than the competition."
"Please be cheaper and more simplified."
"It's a yearly subscription."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
"The price of Splunk is too high for our market."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"The tool's licensing is good and we haven't received any complaints from the team handling it."
"The licensing costs are high for Splunk Enterprise Security."
"The solution is a little expensive."
