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

"The log analysis and reporting are both quite good."
"It has detailed reporting, e.g., user-wise reporting, threat analysis, etc. It also gives you live logs, which can be really helpful during troubleshooting."
"The most valuable feature of Fortinet FortiAnalyzer is its performance."
"What I like the most is the monitoring system."
"Fortinet FortiAnalyzer is a complete package for managing our equipment."
"Anyone who asks me about a Fortinet product, I'll give that person a thumbs-up."
"FortiAnalyzer makes it much easier for us to find an apparently compromised host on the network."
"The IBS (Intent Based Segmentation) and application web filtering are the most valuable aspects of the solution."
"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."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"It doesn't easily integrate with other solutions."
"Fortinet has a new bug every month, which needs to be improved."
"We should be able to do the patch upgrades in a centralized manner. This functionality is currently not there. It would be good to be able to do the firmware updates from one place and at the same time. Currently, if we want to update all appliances, we require FortiManager, which is another solution from Fortinet. Its documentation can be improved. It will be helpful for implementing the product and gaining knowledge for management purposes."
"The support could be better for Fortinet FortiAnalyzer here in Mexico."
"The solution could embed monitoring."
"FortiAnalyzer is a good product; but, I keep thinking that FortiAnalyzer isn't really what I'm looking for which is why I am looking to acquire a SIEM solution."
"The user interface could be a bit more user-friendly, and they could have more robust support."
"For smaller SMB-level firewalls, Fortinet FortiAnalyzer might not be the best idea for cost-effective implementation."
"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."
"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."
"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."
 

Pricing and Cost Advice

"I rate FortiAnalyzer six out of 10 for affordability. FortiAnalyzer pricing isn't steady. It changes each quarter or year. That's one of the main problems in West Abaco because most businesses here are small or medium-sized enterprises. It makes budgeting complicated. You always want to pay the same price on the subscription."
"Fortinet FortiAnalyzer is very expensive."
"Fortinet FortiAnalyzer is quite an expensive tool."
"The solution is quite expensive"
"The price is not expensive when compared to other solutions like Palo Alto."
"There is a license needed to use this solution."
"The cost of the license is high."
"In the local market sometimes people are being charged more than other solutions. Although the market is competitive, legitimate suppliers do not receive a large enough discount to pass onto the customers."
"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."
