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.

"The most valuable feature of the solution is reporting."
"It has a simplified and user-friendly interface."
"FortiAnalyzer ensures you have an accurate view of all your devices, so you don't need to check each one."
"FortiAnalyzer has a robust ability to find a compromised host on your network, and when you identify a compromised host, you can address it."
"Basically, you can see absolutely all activity using FortiAnalyzer."
"FortiAnalyzer helps us discover what's happening on the network."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
"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."
"The product is scalable."
"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."
"A great feature of the solution involves its internal portal."
"A great feature of the solution involves its internal portal."
 

Cons

"The integration between specific tenants and FortiAnalyzer can be simplified when utilizing a multi-tenant EMS for our FortiClient."
"The interface or GUI does not work properly on Microsoft Edge. The behavior or the view is different on Microsoft Edge versus on Chrome or Firefox. When some buttons do not work, I am forced to switch to Firefox."
"The solution could embed monitoring."
"In future releases, we'd like to see more granular reporting. The reports on offer right now are pretty short."
"With other solutions, such as NetFlow Analyzer, you can really customize your report to what you expect, unlike with FortiAnalyzer."
"Pricing-wise, it not affordable for the normal customer. Most of the people want to see different types of reporting, but FortiAnalyzer's fee is a little bit difficult."
"Feature-wise, it is working very well for us. We don't need any additional features. However, its pricing can be improved. For small business customers, price is an important factor."
"Technical support could respond to queries faster."
"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 configurations during initial setup could be improved."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"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 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."
"The support could be better."
 

Pricing and Cost Advice

"The pricing is reasonable."
"The cost of the license is high."
"t varies depending on your needs. However, after-sales support is expensive."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"The product's prices are a bit higher than the other solutions available in the market, but I would say that the tool's quality and support are areas that are good."
"I do not know the price of Fortinet FortiAnalyzer. I did not pay for it, but I know the price of other Fortinet products. They are not cheap. I am from Poland. We have Zloty, not Euro, so for us, everything is expensive."
"It is expensive for small business customers. It is only available for customers with a high number of firewalls to manage or to report. If a customer has only five boxes of FortiGate, the price of FortiAnalyzer can be more than the five boxes. So, we can't easily put this solution for small business customers."
"We pay for an annual license."
"We found the pricing to be quite affordable."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"For a single instance, the price is around $4,000."
