Quotes from Members

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

Pros

"It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security."
"The product's initial setup phase was easy."
"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."

"FortiSIEM's best features are the dashboards and customization."
"The solution is straightforward to set up."
"The most valuable feature is NetFlow."
"It has high stability."
"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 most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"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."
"It offers straightforward integration."
 

Cons

"Fortinet FortiSIEM could improve by having better integration and extensions. This would benefit by allowing us to give more rules."
"The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."
"The nodes on our network did not comply with the SIEM solution. They use a different format parking log."
"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."
"The policy editing should be easier. Right now, it's too hard."
"There could be more AI features included in the product."
"We expect the latest patch from Fortinet FortiSIEM to give the ability to work with signature files."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"The graphical user interface could be improved."
"They should increase the solution's cluster capacity."
"Its filtering feature needs improvement."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"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."
"The security should be improved."
