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 have the most data visibility."
"The ability to gather all gateway information and logs in a single location is the most valuable feature."
"The most valuable features are customizing reports, and the ability to drill down to display critical information in real-time."
"Fortinet FortiAnalyzer comes with a lot of prebuilt reports out of the box, making it easy for our team to generate necessary reports without much struggle."
"It gives you live logs, which can be really helpful during troubleshooting."
"The most valuable features of the solution are the reports and the playbooks."
"The log analysis and reporting are both quite good."
"It supports SQL for logging and reporting. Log data is inserted into the SQL database for log view and report generation."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"The only issue that I can see is with the cost. For example, if you buy support for one year, you are messed up next year. It's better to buy another gateway."
"FortiAnalyzer's price could be lower."
"Fortinet FortiAnalyzer could improve by having better integration with other vendors."
"We should be able to do the patch upgrades in a centralized manner. This functionality is currently not there. It would be good to be able to do the firmware updates from one place and at the same time. Currently, if we want to update all appliances, we require FortiManager, which is another solution from Fortinet. Its documentation can be improved. It will be helpful for implementing the product and gaining knowledge for management purposes."
"The following could be better: operation and maintenance, high-availability architecture, and management link embedded in the transmission link."
"The upgradation process is slow"
"Pricing should be about 10-20% lower."
"The UI could use some improvement. It can be tough for a beginner to navigate because you don't know what to do even if you read the guide. I've talked to some users who said that they couldn't figure out what to do even after looking at the documentation."
"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."
"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

"The number of licenses required directly corresponds with the number of devices connected."
"Fortinet FortiAnalyzer is very expensive."
"The product’s price is much better than its competitors."
"It is acceptable for on-premises, but it is expensive for the cloud."
"​It depends upon the company.​"
"The pricing model is subscription-based."
"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."
"There is a license needed to use this solution."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
