Quotes from Members

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

Pros

"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."
"To add workers and even collectors is pretty easy."
"The most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"It's very easy for anyone to work with."
"Fortinet FortiSIEM needs to provide better API integrations to users."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"The solution’s IP database is awesome."
"The most valuable feature is the anomaly-reporting alarms."
"The most valuable feature is NetFlow."
"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."
"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 solution is straightforward to set up."
 

Cons

"I would like to see easier implementation in the future."
"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."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"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."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"Fortinet FortiSIEM could improve to extend to several locations or sites."
"They should enhance the solution's AI capabilities, including XDR and EDR."
"FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware."
"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 graphical user interface could be improved."
"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."
"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."
 

Pricing and Cost Advice

"The tool is really expensive. For what the tool does for our team, the price is fair."
"Pricing is determined based on the customer's budget."
"Its price can be better. We are Fortinet partners, so we can get discounts, but its price can be an issue at the beginning for others. There is a licensing scheme for every case. There are three licensing schemes that we can choose from."
"Fortinet FortiSIEM is cheaper compared to other products."
"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."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"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."
"We pay for a license for FortiSIEM. We pay for the license and renewal."
"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."
