Amarnath Jaiswal - PeerSpot reviewer
Senior Manager at a manufacturing company with 501-1,000 employees
Comprehensive log analysis has improved traffic monitoring and streamlined risk mitigation
Fortinet FortiAnalyzer is a very comprehensive analyzer providing detailed analyzing features and customizable reports. I can get customization and custom reports, and there are many functions available. It is very good for any organization.Log management in Fortinet FortiAnalyzer is excellent, as it stores approximately two years of logs. Using Fortinet FortiAnalyzer, I analyze vulnerability risks and threats and sort out problems accordingly. I then create policies and mitigate the risk based on my findings. I have created many customizable reports in Fortinet FortiAnalyzer. I have customized the reports to schedule them and generate reports every day that are sent to my email. I am not using any SIEMs, but Fortinet FortiAnalyzer is the best and looks like a SIEM. I did not integrate Fortinet FortiAnalyzer with any security information and event management solutions. With Fortinet FortiAnalyzer, I have streamlined the process to mitigate risks and save time to get event information on any type of threats, risks, and unwanted traffic. Risk and time are saved, and it is valuable for any organization.

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

"With Fortinet FortiAnalyzer, it is easy to get reports and read specific logs."
"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."
"Report generation is very easy"
"FortiAnalyzer makes it much easier for us to find an apparently compromised host on the network."
"The most valuable feature of Fortinet FortiAnalyzer is the capturing of traffic for reports."
"FortiAnalyzer has a robust ability to find a compromised host on your network, and when you identify a compromised host, you can address it."
"The capability of logging in Fortinet FortiAnalyzer is great because there is no need to go to each individual box to check the traffic details."
"We have other log analyzers, but we have found with Fortinet FortiAnalyzer when you have a Fortinet environment, it's fully integrated."
"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 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. 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."
 

Cons

"It should have customized reports as well. While it currently has them, you need to write a script which is not straightforward."
"The support engineers are very slow and incompetent."
"I do not recommend Fortinet FortiAnalyzer for bigger companies because it is not scalable enough."
"A possible improvement for FortiAnalyzer could be in threat intelligence. This feature might be enhanced to provide better insights and more efficient operations."
"Fortinet FortiAnalyzer needs to improve its pricing flexibility."
"It's possible that they could add some advanced analytics and some proactive controls for logging analytics. That will help a lot."
"I need some improvements in the support team since it is an area where there are certain shortcomings."
"The support could be better for Fortinet FortiAnalyzer here in Mexico."
"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. 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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved."

"The pricing is reasonable."
"We have several products including Fortinet Wireless, FortiGate Firewalls, and FortiAnalyzer, which are bundled together and cost approximately $50,000 USD annually."

"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."

"For a single instance, the price is around $4,000."
