Monitoring capabilities keep operations running smoothly and alerts enhance proactive system management
We use FortiMonitor to monitor the infrastructure of our customers. We check on what is happening with their operations, monitor bandwidth, ensure configurations are appropriate for the customer, and identify if anything is going wrong The most valuable features of FortiMonitor are its redundancy…

Alerting precision has reduced incident response times and improved department-level network visibility
The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

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

Pros

"FortiMonitor's dashboard is very informative and user-friendly."
"FortiMonitor is 100% stable."
"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"The most valuable feature of FortiMonitor is the overall ability to monitor the health of the environment."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"The most valuable feature of this solution is what the devices are used for. We have big backups for our Cradlepoint solutions, but FortiMonitor is a great routing device and we love working with them."
"Overall, I would recommend FortiMonitor to others."
"The product's initial setup phase is easy."
"PRTG Network Monitor has positively impacted my organization as the hourly basis has been reduced, making a significant impact."
"The authentication links into our standard Active Directory authentication, which is very good."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"The solution is very easy to use and the web provides information with ease."
"PRTG Network Monitor has positively impacted our organization by saving us a significant amount of money; during maintenance windows or patching, we used to receive false alerts, but since implementing PRTG, it has saved us thousands of dollars and has become a boon for us by providing convenience and being time and cost-saving."
"The tool is integrated with our email for the alerts."
"It is great for service level agreements and can comply fully with internet monitoring or any interface."
"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."
 

Cons

"Additionally, there are no AI features in FortiMonitor, which might be an area for enhancement."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"The tool's price in Vietnam is high, making it an area of concern where improvements can be made."
"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"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."
"There are no AI features in FortiMonitor, which might be an area for enhancement."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."
"I wouldn't mind better categories for the sensors. When I go to add a new sensor for a new device, there are some categories in there already, and they can be filtered out, but there's quite a large pool of sensors... When I want to go in and find something quite specific, I have got to scroll down and scroll down to find what I'm actually looking for,"
"I would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."
"The Desktop app is good but it can be really sluggish at times, especially when you're editing different elements."
"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."
"The desktop app is the one area where it do with some improvement. From a user's perspective, I would like to be able to get more out of the desktop app as opposed to where we are now with it."
"I would like to have a VM version that can be installed on a cloud such as Azure. We're using Azure, and we're eliminating on-premise servers. It would be helpful to have a PRTG version that can be installed on the Azure cloud."
"I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour."
 

Pricing and Cost Advice

"Compared to other solutions, FortiMonitor is a very expensive solution."
"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."
"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."
"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."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"We pay for a perpetual license and we have a support fee."
"We are using the basic PRTG that we can download for free. For now, we only need to monitor less than 100 devices. For more than 100 devices, we would need to buy a license. PRTG is much cheaper than SolarWinds."
"We are licensed for 2500 endpoints."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."
"The pricing is reasonable for the features provided."
"The price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."
"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."
"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."
