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

"The most valuable features of Fortinet FortiAnalyzer are the dashboards and supporting services."
"Provides detailed log reports"
"Log collection is the most valuable. The UI looks great. It has a very good look and feel. We don't have the need to use solid state drives. We use mechanic drives, and we don't see any performance issues, so basically, it is doing fine."
"The product can scale."
"Stability-wise, I rate the solution a ten out of ten since, in our company, we have never experienced the solution crashing or having any other issues."
"There are a lot of monitoring features available."
"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."
"It's a very stable product."
"A great feature of the solution involves its internal portal."
"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."
"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."
"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."
 

Cons

"The FortiAnalyzer is not good at managing multi-version environments. If all your FortiGate are at different versions in the field, that's difficult. The one thing we didn't like is the fact you have to have 100% of your environment at the same release, which is not pleasant, to have it fully functional. You can have a different release, but to have it fully functional 100% of your environment has to be the same release."
"We are concerned about the compliance of our policy and institutional philosophy."
"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."
"Fortinet FortiAnalyzer could improve by offering more detailed packet inspection information, especially where packets get dropped."
"The cloud version can be expensive. If the customers could get the resources to store the logs on-premises, it would be much better."
"The solution could improve by allowing the ability to search logs in integrated solutions."
"Software reports are good but should match the dashboard and include top-level output instead of just base or low-level devices."
"The traffic monitoring could be better, and stability could be improved."
"The support could be better."
"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 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."
"The support could be better. They only offer email support."
"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."
 

Pricing and Cost Advice

"When you compare with other firewall vendors, FortiAnalyzer is quite competitive in pricing."
"The product’s price is much better than its competitors."
"I believe that these devices were procured with a five-year maintenance and support license up front. I work at a university, so the vendor provides a considerable higher ed discount."
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."
"Fortinet FortiAnalyzer is quite an expensive tool."
"I rate Fortinet FortiAnalyzer's pricing as five out of ten."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"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."
