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.

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 is very easy to deploy."
"I have found incident management and also identifying new threats, analyzing the network traffic, and finding out the issues with the network traffic such as any security issues to be valuable. I also like the compliance reports."
"The initial setup is easy; it's a very stable product that we can scale, with generally good support, pretty good documentation, and an interface I like."
"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."
"The solution is easy to use and easy to integrate."
"FortiAnalyzer helps us discover what's happening on the network."
"The reporting features, which offer customization, real-time insights, and compliance support, are particularly noteworthy aspects."
"There are a lot of monitoring features available."
"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."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
"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."
 

Cons

"Sometimes, there is a problem with CPU consumption, where one process consumes 100%, and I need to restart FortiAnalyzer to fix this."
"The following could be better: operation and maintenance, high-availability architecture, and management link embedded in the transmission link."
"Feature-wise, it is working very well for us. We don't need any additional features. However, its pricing can be improved. For small business customers, price is an important factor."
"The traffic monitoring could be better, and stability could be improved."
"Their in-house technical support is extremely slow to respond. We have our own in-house team to manage issues so clients don't have to wait over two weeks for a response to issues."
"The UI could use some improvement. It can be tough for a beginner to navigate because you don't know what to do even if you read the guide."
"The solution does not function well with third-party tools"
"I'm looking for something more efficient to analyze different foreign things. That's why FortiSIEM could compete with FortiAnalyzer."
"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."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The support could be better."
"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."
 

Pricing and Cost Advice

"The product’s price is much better than its competitors."
"Compared to other products, the price is a little bit high."
"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."
"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"There is a license needed to use this solution."
"We have several products including Fortinet Wireless, FortiGate Firewalls, and FortiAnalyzer, which are bundled together and cost approximately $50,000 USD annually."
"I believe that Fortinet is a cost-effective brand, making it a competitive option in terms of pricing."
"The price of Fortinet FortiAnalyzer is expensive."
"We found the pricing to be quite affordable."
"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."
