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.
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 can see, for example, the utilization of all of the security fabric in a report, getting PDFs and Excel sheets that we can use to analyze everything, including how users are working on our internet services, and we can generate reports quite easily."
"Log View is the most valuable part for us, as we can view logs from different Fortigates on a single GUI."
"Before using FortiAnalyzer, people would surf wherever and we could not monitor or see which computer in the company goes where, but now, using the analyzer, I am able to see each IP separately, including user name and other stats, so when the police called and told me someone from the company was breaking the law, I was able to monitor the specific computer."
"The user interface is good and it is quite easy to use."
"The ability to gather all gateway information and logs in a single location is the most valuable feature."
"The initial setup is pretty straightforward."
"The most valuable features of Fortinet FortiAnalyzer are the dashboards and supporting services."
"Overall we are satisfied with all the features the solution provides."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
"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."
"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."
"The product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"Fortinet FortiAnalyzer should come bundled with other Fortinet solutions. Additionally, the performance and updates could improve."
"I think technical support should be better. Sometimes support from Fortinet does not help with creating policies or configuration issues and directly routes to the service integrator."
"One of the main disadvantages is not having a direct link to the security policy when you see something in the log."
"With other solutions, such as NetFlow Analyzer, you can really customize your report to what you expect, unlike with FortiAnalyzer."
"Technical support could respond to queries faster."
"The technical support isn't very good, I rate it a 2 out of 5."
"We would like to see some improvement on the upgrade process around this solution. There are sometimes communication issues when a new version of the firewall is implemented, and it fails to report back to this product."
"This is a good product, but I think there are better ones for log analytics."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The support could be better. They only offer email support."
"The support could be better."
"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."
"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."
