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

"It provides the best firewall features."
"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."
"The product's initial setup phase is easy."
"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."
"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."
"Overall, I would recommend FortiMonitor to others."
"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The solution has a lot of plugins and scripts integrated with it."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"Nagios is my favourite open source monitoring system."
"Nagios is the best software of its kind if you have time for configure any host and network, and you can do quite everything with a bit of scripting."
"Nagios has good scalability."
 

Cons

"I think the current features are really good for me, nothing else comes to mind right now. Maybe some small improvements could be made in the customization and configuration part of the UI to make it easier or more intuitive. Customizable UI options, like we saw in the demo, could be helpful for everyone. But in our operational environment, having clear health status and system details is crucial for us system engineers. One feature I'd really like to see is a credential management system. It would help us keep track of who's logged in and how many times, which is important due to user restrictions. Sometimes, we need to manage logins more efficiently, like logging off other users to free up credentials. So having a feature like that would be really helpful."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"For our type of country, it is always expensive, but it has competitive pricing."
"FortiMonitor needs to improve its alert system."
"There are areas for improvement that FortiManager is addressing."
"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."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"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."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"It's in need of more standard plug-ins."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"For some, it may be difficult to deploy."
"The installation and monitoring need improvement."
 

Pricing and Cost Advice

"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."
"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 tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"There are additional costs needed for certain functionality, such as scalability."
"FortiMonitor's price is very high."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"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."
"Licensing costs are reasonable."
"Nagios XI is an expensive 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."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
