Managing diverse networks with detailed alerts enhances device oversight
FortiManager is very helpful in managing our networks. We use it to manage 20 farms and various networks with hundreds of devices. The version we are using provides more detail than the older dashboard. We appreciate the alerting capabilities, which are integrated with SolarWinds to notify our team via SMS.

A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product's initial setup phase is easy."
"FortiMonitor's dashboard is very informative and user-friendly."
"Overall, I would recommend FortiMonitor to others."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"The solution helps to see client infrastructure. It has many boxes and blinks green or red when the station goes up or down. We have different domains for the device groups that we monitor."
"FortiMonitor is 100% stable."
"The most valuable feature of FortiMonitor is the overall ability to monitor the health of the environment."
"The most valuable feature of FortiMonitor is user monitoring, as we are able to see if the user is following the policy or not from their system, and additionally the solution integrates well with Fortinet FortiGate and has centralized management."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"Being open source lets us customize it for our monitoring needs, saving us money."
 

Cons

"For our type of country, it is always expensive, but it has competitive pricing."
"There is room for improvement in the FortiMonitor report. It is not ideal for showcasing to tech customers or managers, especially when trying to display high CPU usage from logins within a specific range of months or the most recent month."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"We use FortiToken, and it's a pain to use because you have to send things through your phone and then confirm by email. Only after this can you log in. It's dual-factor authentication. I wish that I could just log in or bring up a dashboard where I could log in from."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
 

Pricing and Cost Advice

"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"There are additional costs needed for certain functionality, such as scalability."
"In terms of licensing, while it may not be the most expensive option on the market, it's relatively cost-effective. You can obtain licenses at a lower cost, with the calculation being straightforward. For example, if you onboard around 5,000 devices, you'll need approximately 5,000 licenses, as each device typically counts as one license."
"On a scale from one to ten, I rate the pricing a nine since it is a good solution that is available at a cheap price."
"The tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"FortiMonitor's price is very high."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"The pricing is quite reasonable, especially when compared to the broader market."
