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

"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"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."
"FortiMonitor is a great compliment to Cradlepoint; we have big backups for our Cradlepoint solutions, but FortiMonitor is a great routing device and we love working with them."
"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 most valuable feature of FortiMonitor is user monitoring. We are able to see if the user is following the policy or not from their system. 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."
"The most valuable feature of FortiMonitor is the overall ability to monitor the health of the environment."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"I can monitor a software made in-house to software of bigger companies."
"Overall, it's a powerful system."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"Nagios is my favourite open source monitoring system."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
 

Cons

"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"There are no AI features in FortiMonitor, which might be an area for enhancement."
"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 improve by having compatibility with other operating systems, such as Linux."
"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."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Technical support is an area that needs improvement. It is not available 24/7."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The GUI could be improved."
"The reporting structure could be more streamlined."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
 

Pricing and Cost Advice

"The tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"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."
"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."
"There are additional costs needed for certain functionality, such as scalability."
"As it is not an agentless tool, I think it is expensive."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"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."
"The pricing is high with separate licensing for the product and support."
