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 can see, for example, the utilization of all of the security fabric in a report, getting PDFs and Excel sheets that we can use to analyze everything, including how users are working on our internet services, and we can generate reports quite easily."
"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."
"The most valuable aspect of the solution is its ability to pinpoint where the issue is, and if two devices need to communicate together, you can see which interfaces they are using."
"One of the most valuable features is the ability to analyze data in real-time using AR features to pull data from the industrial DB. You can know what is going on and see in milliseconds where the network is underperforming."
"The feature I find most useful is the handy dashboard."
"It is one of the best firewall products."
"Its robust security and performance are the two main features. We also use the log reporting feature."
"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 product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
"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."
"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."
"A great feature of the solution involves its internal portal."
 

Cons

"With other solutions, such as NetFlow Analyzer, you can really customize your report to what you expect, unlike with FortiAnalyzer."
"The problem is that it can´t recognize logs from FortiController blades, not even specifying it as a syslog device so this is a big lack."
"The support engineers are very slow and incompetent."
"When somebody is new to the system they find it difficult to perform certain operations, like backups, and to see where the reports are."
"However, its pricing can be improved. For small business customers, price is an important factor."
"When it comes to pushing logs to a SIEM, most of the time we have some issues when it comes to filtering."
"Fortinet FortiAnalyzer is not in the cloud environment like some of the other products. There could be a possibility of extending its functionality to the cloud environment. If possible, they could have a deal with or integrate with other firewall manufacturers, like Palo Alto and Cisco, and mix the information. It is a difficult functionality. I don't know if any product in the market provides such functionality."
"The traffic monitoring could be better, and stability could be improved."
"The configurations during initial setup could be improved."
"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. They only offer email support."
"The support could be better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"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."
 

Pricing and Cost Advice

"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."
"The number of licenses required directly corresponds with the number of devices connected."
"Fortinet FortiAnalyzer is quite an expensive tool."
"The program is expensive."
"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"I won't say the solution is too costly since it is available at a fair price."
"The pricing is reasonable."
"All Fortinet programs come at a good price."
"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."
