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

"We like the fact that we can run minute-by-minute reporting form this solution."
"The traffic log information we receive from Fortinet FortiAnalyzer is valuable."
"The scalability is good. It is also good in the cluster nodes. You can make multiple FortiAnalyzer clusters groups, and you can distribute the logs between these FortiAnalyzer nodes. In other words, you can expand the scale."
"I recommend Fortinet FortiAnalyzer."
"Based on the logs of Fortinet FortiAnalyzer you can have it trigger actions. For example, if the log has a word or a sentence you specified it can send an alert or Syslog to an email address."
"The most valuable feature of the solution is reporting."
"The dashboard of Fortinet FortiAnalyzer is outstanding with very detailed information."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
"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."
"The product is scalable."
 

Cons

"FortiAnalyzer only integrates with Fortinet solutions. That is a limitation because many organizations use multiple vendors. It's often a mixture of Cisco network hardware and equipment from other vendors, such as switches, access points, etc."
"When it comes to pushing logs to a SIEM, most of the time we have some issues when it comes to filtering."
"For smaller SMB-level firewalls, Fortinet FortiAnalyzer might not be the best idea for cost-effective implementation."
"The technical support is not very reliable."
"The solution could improve by allowing the ability to search logs in integrated solutions."
"Fortinet FortiAnalyzer could improve by offering more detailed packet inspection information, especially where packets get dropped."
"Though FortiAnalyzer has improved over the last few versions, the user interface still has room for improvement. It's a bit dated-looking."
"There are a lot of solutions on the market and Fortinet FortiAnalyzer is limited. It cannot be used across multiple vendors. They can improve by advancing their technology."
"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."
"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."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."

"We found the price of Fortinet FortiAnalyzer to be reasonable."
"The pricing is reasonable."
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"All Fortinet programs come at a good price."
"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."
"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."
