Network Engineer III at a energy/utilities company with 1,001-5,000 employees
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

"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"FortiMonitor's dashboard is very informative and user-friendly."
"The tool continuously improves, adapting to support new vendors and technologies. Importantly, it automates the process, triggering alerts when devices require attention, and eliminating the need for manual intervention."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"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."
"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"Overall, I would recommend FortiMonitor to others."
"The most valuable feature of FortiMonitor is the overall ability to monitor the health of the environment."
"Nagios XI helped me to draw the network and check for system failures."
"I can monitor a software made in-house to software of bigger companies."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"The overall performance of the product is superb."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The technical support is good."
 

Cons

"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"The tool's price in Vietnam is high, making it an area of concern where improvements can be made."
"There are areas for improvement that FortiManager is addressing."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"FortiMonitor's monitoring could be much better. It should be like, in Palo Alto."
"FortiMonitor needs to improve its alert system."
"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."
"I feel that the maturity and user interface needs to be improved."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"We'd like to see more integration capabilities."
"The GUI could be improved."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
 

Pricing and Cost Advice

"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."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"There are additional costs needed for certain functionality, such as scalability."
"FortiMonitor's price is very high."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"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."
"Licensing costs are reasonable."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"We are using the free version of this solution."
"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."
