Simplifying log management by displaying detailed access information
The most valuable feature of Fortinet FortiAnalyzer is its ability to simplify and display logs clearly, providing details like which IPs are accessing the system, the destination, and the policies applied. This visualization and detail make managing logs more straightforward. In conjunction with our VMware setup, Fortinet FortiAnalyzer enhances organizational efficiency, meeting the standard log retention period for up to a year.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"It has detailed reporting, e.g., user-wise reporting, threat analysis, etc. It also gives you live logs, which can be really helpful during troubleshooting."
"It is kind of a very good network packet analyzer solution; it does what a network analyzer should do, and it does it very well."
"We have other log analyzers, but we have found with Fortinet FortiAnalyzer when you have a Fortinet environment, it's fully integrated."
"The stability of the solution is excellent; it's very robust, we don't have issues with bugs or glitches, it doesn't crash or freeze, and it's extremely reliable."
"From my perspective, we need to see the traffic in a good way so we can know what has happened in our network. The analyzing tools and the monitoring tools and the logs are the important part in the network."
"The IBS (Intent Based Segmentation) and application web filtering are the most valuable aspects of the solution."
"I like its simplicity."
"Logging is the best feature, and I like how everything is integrated with the FortiGate devices, FortiAuthenticator, and other fabric devices, giving you all the login information details and great user connectivity, while being easy to set up, stable, scalable, and very user-friendly."
"A great feature of the solution involves its internal portal."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
"A great feature of the solution involves its internal portal."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."

Cons

"The solution does not function well with third-party tools"
"The UI needs to be improved in future updates."

"Sometimes, there is a problem with CPU consumption, where one process consumes 100%, and I need to restart FortiAnalyzer to fix this."
"The pricing could be better."
"In future releases, we'd like to see more granular reporting. The reports on offer right now are pretty short."
"FortiAnalyzer's price could be lower."
"It should have customized reports as well. While it currently has them, you need to write a script which is not straightforward."
"The support could be better. They only offer email support."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The support could be better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
