Quotes from Members

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

Pros

"FortiSIEM is a great tool for making security processes transparent."
"Analytics. It can provide log information from the device. With log information, I can see if there is a threat"
"It is used as an alerting platform."
"The product's initial setup phase was easy."
"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 product is quite well-organized. The GUI makes it easy to navigate."
"Fortinet FortiSIEM is highly scalable. I would rate its scalability nine out of ten."
"The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."
"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."
"The solution is straightforward to set up."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"The most valuable feature is NetFlow."
"It offers straightforward integration."
"It has high stability."
"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."
 

Cons

"There could be improvements like introducing some solutions directly into FortiSIEM to avoid the need for separately purchasing additional tools like FortiStore."
"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."
"Fortinet FortiSIEM needs to provide better API integrations to users."
"Fortinet FortiSIEM could improve by having better integration and extensions. This would benefit by allowing us to give more rules."
"Customer support service could be better."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"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 policy editing should be easier. Right now, it's too hard."
"They should increase the solution's cluster capacity."
"The security should be improved."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"Its filtering feature needs improvement."
"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."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"The graphical user interface could be improved."
 

Pricing and Cost Advice

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"There are additional features that cost more than the standard licensing fees."
"There is a need to make yearly payments towards the licensing charges attached to the product. The free version license of the product is available for two months."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"Please be cheaper and more simplified."
"This is probably more on the lower cost end of the spectrum compared to competing products. Fortinet's license model is based on events per second, which makes sense, but that's not typical. It makes it very hard to calculate what your costs are going to be as you scale the platform because some log sources, such as firewall logs, are very noisy, and there are lots and lots of events per second, but some of them are not. So, it becomes a bit of a science experiment trying to guess what your costs are going to be as you scale the solution. This is where other competing products perhaps have a more straightforward license model."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"The solution is highly-priced."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
"The solution's price is reasonable."
