Amarnath Jaiswal - PeerSpot reviewer

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 solution does what it is supposed to. I want it to do reports for Fortinet and it does it well."
"The system provides valuable insights through information, graphics, and reports."
"The user interface is good and it is quite easy to use."
"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."
"The report templates are valuable, it works very well, and integrations also work well."
"Special notifications about compromised phones are valuable because we have some guest networks, and sometimes, people are connecting phones that are connected to compromised websites. We want to be informed about it. We sometimes have some cases where we want to analyze the connection from inside to outside ports. So, it helps with a lot of things. It depends on our needs."
"Fortinet FortiAnalyzer is very helpful if you are really into FortiGate devices."
"It's a very stable product."
"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."
"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."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"Pricing should be about 10-20% lower."
"The deployment is complex and has room for improvement."
"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 price is quite expensive. Fortinet products are very expensive."
"There are a lot of solutions on the market and Fortinet FortiAnalyzer is limited. It cannot be used across multiple vendors."
"The log view for syslog in Fortinet FortiAnalyzer could be improved. A more comprehensive dashboard for syslog would enhance its value."
"I think some improvement is required in real-time log monitoring, as sometimes it gets stuck or displays results after a delay."
"I would like to see an improvement in the technical support. Stronger authentication will also be a plus."
"The support could be better."
"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."
"The support could be better. They only offer email support."
"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 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."
 

Pricing and Cost Advice

"I rate the product's price a six on a scale of one to ten, where one is cheap, and ten is expensive."
"I won't say the solution is too costly since it is available at a fair price."
"It is expensive for small business customers. It is only available for customers with a high number of firewalls to manage or to report. If a customer has only five boxes of FortiGate, the price of FortiAnalyzer can be more than the five boxes. So, we can't easily put this solution for small business customers."
"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."
"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"I would rate the price of FortiAnalyzer as seven out of ten, with ten being the most expensive."
"The price of Fortinet FortiAnalyzer is expensive."
"Its price is okay for us. Fortinet products are cheaper than other solutions."
"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."
"We found the pricing to be quite affordable."
