Featured Reviews

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…

Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.

Quotes from Members

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

Pros

"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"AccelOps can handle a lot of data and it's just so important to true monitoring. Also, I can create a lot of rules to detect anything I like."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"FortiSIEM helped us discover all the threats at the time that were attacking the IT services of the company. We now have multiple-level authentication."
"The most valuable features of Fortinet FortiSIEM are the SD-WAN, Global LAN, and application controls."
"The solution is easy to use and user-friendly."
"Fortinet FortiSIEM is less costly than other products and is available 24/7."
"Analytics is the most valuable feature. The business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
 

Cons

"The log collection and configuration management are not great."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"When an alert triggers in Fortinet FortiSIEM, the layout or format can feel limited"
"The performance can be improved. Sometimes it takes a long time to fetch data."
"With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk."
"It would be good if the solution offered even more configuration options, especially in relation to the VPN so that it continues to be a very flexible option."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"Sometimes, if there are changes made by a user on a database server, it can be difficult to get that information on the fly. I would like to see a situation where once I specify a user with the database server I need, and with the changes they have performed on that, I don't need to continue my search pattern to drill down just to get the information."
"Graylog Security needs to incorporate security scorecards."
 

Pricing and Cost Advice

"Please be cheaper and more simplified."
"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."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"The price is competitive."
"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."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"I rate the tool's pricing a one out of ten."
