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

"We use this functionality every day, and obtain reports on things like how many people are using the VPN, which websites are being accessed, and whether hackers are trying to penetrate into our network."
"Technical reports clearly identify system checks, locations and areas, how many times things escape, which firewall is affected, and source IDs."
"Log View is the most valuable part for us, as we can view logs from different Fortigates on a single GUI."
"The initial setup is easy, and the deployment is fast."
"The most valuable is its robust and comprehensive reporting functionality, providing a thorough overview of various metrics."
"The most valuable features are customizing reports, and the ability to drill down to display critical information in real-time."
"The scalability of Fortinet FortiAnalyzer is excellent at a rating of ten out of ten."
"For us in Latin America, the best features of Fortinet FortiAnalyzer are the solutions that combine SD-WAN and security in the same box."
"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. 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."
"A great feature of the solution involves its internal portal."
 

Cons

"There is no issue with the hardware appliance. However, when discussing the cloud options, they offer very limited features, especially in terms of reporting and analyzing data."
"They can include integration with devices, such as firewalls, endpoints, from other vendors. They can include graphic monitoring of everything in the network, not just Fortinet products. It would also be good to include customizable reports and customizable views of the reports."
"A possible improvement for FortiAnalyzer could be in threat intelligence."
"The setup of the solution can be improved because it is currently complex."
"The pricing could be better."
"The solution can improve the incident response function to provide more detailed information on where the incident is originating."
"Though FortiAnalyzer has improved over the last few versions, the user interface still has room for improvement. It's a bit dated-looking."
"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."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The support could be better."
 

Pricing and Cost Advice

"The product’s price is much better than its competitors."
"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."
"The hardware cost and services contract are fair."
"It is acceptable for on-premises, but it is expensive for the cloud."
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"The enterprise version of this solution is costly. We have considered FortiAuthenticator for network control, but the pricing was focused on the larger companies and didn't suit our needs as a smaller business."
"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"The cost of the license is high."
"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."
"We found the pricing to be quite affordable."
