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.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"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."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"It provides the best firewall features."
"FortiMonitor's dashboard is very informative and user-friendly."
"In FortiMonitor, we're linked up with our Netgear, CactusServer, and NOC. It's really valuable because everything's migrating to one dashboard for us system engineers. We can keep an eye on traffic, blocked sites, and the health of our hardware. That last part, about knowing if something's going to fail soon, is super important. It gives us time to sort things out before any big problems happen. As a system engineer, I need to keep tabs on everything – temperature, monitoring systems, and network operations. This data is really handy because it helps me ensure our site runs smoothly, whether it's turning systems on or off. Just last night, there was a system failure, but thanks to real-time monitoring, I quickly identified the problem and got the necessary replacement parts."
"Fortinet's customer support is very good."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"The ROI is very good."
"I can monitor a software made in-house to software of bigger companies."
"It's an essential part of our infrastructure, and we'll keep using it."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The most valuable feature is the monitoring of processes."
 

Cons

"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."
"The solution's initial setup process is time-consuming."
"The tool's price in Vietnam is high, making it an area of concern where improvements can be made."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"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."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"FortiMonitor needs to improve its alert system."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The reporting structure could be more streamlined."
"We're still experiencing stability issues with regards to collecting performance graphs."
"The user interface needs improvement."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
 

Pricing and Cost Advice

"FortiMonitor's price is very high."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"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."
"There are additional costs needed for certain functionality, such as scalability."
"The tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"The licensing fees for this solution are approximately $3,000 USD per year."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
