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 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."
"These aspects make Fortinet FortiSIEM a valuable choice."
"The most valuable feature is auto-discovery. When you send logs from any device to port 514, it helps register those devices automatically."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"We have found the most important features in Fortinet FortiSIEM to be the correlation, file utility check, latest file, and hash changes. These features are important for us."
"This solution offers extensive customization options, making it possible to adapt it precisely to their requirements."
"There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not."
"It's very easy for anyone to work with."
"The solution is straightforward to set up."
"The tool's most valuable feature is the encryption feature. From a security perspective, the solution hasn't significantly strengthened our security posture. However, it has greatly improved performance by streamlining encryption processes and avoiding encryption at multiple layers. This has also simplified troubleshooting, as we can whitelist certain processes."
"The most valuable feature is NetFlow."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"It offers straightforward integration."
"It is a good product. It provides network visibility, which is important. Gigamon can bring some optimizations to my network. It is helpful for security inspection, and it makes my firewall work fast because my firewall doesn't have to do the inspection of the SSL connections, for example."
"It has high stability."
 

Cons

"FortiSIEM could be better integrated with other vendors."
"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."
"There could be more AI features included in the product."
"When an alert triggers in Fortinet FortiSIEM, the layout or format can feel limited"
"The challenge I face with Fortinet FortiSIEM is the lack of support."
"They need to integrate better with Cisco and Palo Alto."
"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."
"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."
"The graphical user interface could be improved."
"Its filtering feature needs improvement."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"The security should be improved."
"The Gigamon Deep Observability Pipeline should have a feature showing the traffic flow within its platform. Currently, customers have to use separate tools for monitoring, which is inconvenient. If it had its visibility feature, it would make monitoring easier and more complete without needing extra tools."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"They should increase the solution's cluster capacity."
 

Pricing and Cost Advice

"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"Fortinet FortiSIEM is not an expensive solution."
"We pay for a license for FortiSIEM. We pay for the license and renewal."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"Please be cheaper and more simplified."
"There are additional features that cost more than the standard licensing fees."
"Fortinet FortiSIEM is cheaper compared to other products."
"The solution's price is reasonable."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
"The solution is highly-priced."
