Manikandan Kannan - PeerSpot reviewer
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.
Syarul Idzuddin Adzmi - PeerSpot reviewer
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

"FortiAnalyzer's best feature is centralized log analysis. It's based on SQL database, so I can fully customize my report, chart-wise and log-wise, and can create as many reports as I want without any limit."
"The feature that I have found the most valuable is to be able to see everything in our network in a single task. A single menu and the graphical bar charts that it provides to give insights are very useful. It also gives very good metrics on bandwidth utilization, CPU, and device performance. It is very simple and easy to use as well."
"The dashboard of Fortinet FortiAnalyzer is outstanding with very detailed information."
"The user interface is good and it is quite easy to use."
"It gives us reporting features, which are helpful in the case of troubleshooting and audit purposes."
"The most valuable features of the solution are the reports and the playbooks."
"The log analysis and reporting are both quite good."
"It is very stable and reliable."
"The product is scalable."
"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 initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
 

Cons

"When using this solution, you need a high-level expert to make it work as it should."
"One thing we struggled with FortiAnalyzer was integration with SIEM. We also had issues with the new threats and APTs. There were false positives, so we needed to have some ratings related to false positives."
"The technical support is not very reliable."
"I feel that Fortinet FortiAnalyzer is a little bit heavy, making it an area where improvements are required."
"The UI can be more user-friendly for new users."
"The integration between specific tenants and FortiAnalyzer can be simplified when utilizing a multi-tenant EMS for our FortiClient."
"The integration with other vendors for log collection could be enhanced."
"They need to make the monitor 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."
"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 price of Fortinet FortiAnalyzer is expensive."
"The number of licenses required directly corresponds with the number of devices connected."
"The company's choice to utilize Fortinet FortiAnalyzer was based on the overall security strategy and compatibility with existing solutions. It was deemed the best fit as it provided a centralized point of visibility for all of their security solution, including Fortinet FortiGate firewall, FortiClient, Forti EMS, and FortiAP. The company conducted a thorough evaluation of various solutions in the market but found that none of them could fully integrate and manage all their solutions as effectively as Fortinet FortiAnalyzer."
"We pay for an annual license."
"The program is expensive."
"t varies depending on your needs. However, after-sales support 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."
"I rate Fortinet FortiAnalyzer's pricing as five out of ten."
"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."
