Quotes from Members

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

Pros

"Analytics is the most valuable feature. The business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
"This solution offers extensive customization options, making it possible to adapt it precisely to their requirements."
"The most valuable feature is the anomaly-reporting alarms."
"The seamless integration with FortiGate is the solution's most valuable aspect."
"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."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"It gives us the opportunity to generate notifications based upon rules that get triggered, and the rules could be specific to PCI, HIPAA, GIBA, NIST, and so forth."
"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."
"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 has high stability."
"The most valuable feature is NetFlow."
"The solution is straightforward to set up."
"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 offers straightforward integration."
 

Cons

"The UI could improve in Fortinet FortiSIEM. Humans view the UI frequently for data and if it was more visually pleasing it would be beneficial."
"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."
"The dashboard needs to improve."
"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."
"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."
"They should enhance the solution's AI capabilities, including XDR and EDR."
"Network detection and response is a separate product."
"There is no proper guide for integration or configuration."
"Its filtering feature needs improvement."
"The graphical user interface could 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."
"The security should be improved."
"They should increase the solution's cluster capacity."
"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."
 

Pricing and Cost Advice

"Fortinet FortiSIEM is cheaper compared to other products."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"They have a yearly subscription."
"Manageable, however would be better as pay as you go versus CapEX."
"There are additional features that cost more than the standard licensing fees."
"Pricing is determined based on the customer's budget."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"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."
