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 program is stable and it gives me great visibility."
"The most valuable feature of FortiAnalyzer is its visibility, especially in network investigations."
"FortiAnalyzer helps us discover what's happening on the network."
"For those organizations that need to use a product for reporting or some analysis of logs, this is a good solution."
"It is kind of a very good network packet analyzer solution; it does what a network analyzer should do, and it does it very well."
"We are using this solution, and we are getting good results."
"Fortinet FortiAnalyzer is easy; for customers with basic knowledge and for those who do not have a technical background, Fortinet is quite good and it should be the first choice."
"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 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."
"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."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"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. 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."
 

Cons

"It is very important that FAZ can support FortiController as the architecture designed for the network. FortiController should be registered in FAZ at least for event logs."
"FortiAnalyzer only works with other Fortinet products. If you need to analyze the data from other devices, other vendors, this solution is not the best one to use."
"Technical support has been very bad. They should work to improve their level of service."
"I don't find Fortinet FortiAnalyzer to be as robust as Check Point Security Management."
"It will be better if behavior or indicators of compromise were on the same licensing schema. Currently, it is an advanced feature that you have to purchase as an add-on. This is the reason we're trying to do the ELK so that we can integrate them and create those rules by using open-source software. It will also be better if it has some more integration with IT service management tools so that we can do endpoint protection and response based on those indicators of compromise or those behavior analysis rules that create events that can automatically flow. We can inject that data into a service incident ticket on our IT service management tool, and that way we can assign the ticket to the proper teams and respond right away. Currently, we only have integration with ServiceNow."
"Their pricing model is not the best and needs work."
"Technical support could respond to queries faster."
"I would like to see an improvement in the technical support. Stronger authentication will also be a plus."
"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 configurations during initial setup 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."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"There is a license needed to use this solution."
"The program is expensive."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"We pay for an annual license."
"I would rate the price of FortiAnalyzer as seven out of ten, with ten being the most expensive."
"​It depends upon the company.​"
"We found the price of Fortinet FortiAnalyzer to be reasonable."
"We found the pricing to be quite affordable."
"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."
