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.

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

"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, 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 offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"It provides the best firewall features."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"FortiMonitor is 100% stable."
"The product's initial setup phase is easy."
"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"The initial setup is pretty easy."
"PRTG Network Monitor helped prevent incidents by creating an alert to the DL when servers go down, notifying me before it became a bigger problem."
"The pricing of the solution is pretty good; we don't find it too unreasonable, and it offers good integration capabilities with an initial setup that was easy and rolled out smoothly."
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"The alerting system is very stable, and it's helpful whenever any sensor is down."
"Nice product with an easy interface to use and a large variety of sensors."
"If you need a simple and solid tool, and you're willing to spend a buck, it's a good option to consider."
"Network Discovery is a feature that our customers like a lot."
 

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."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"There are areas for improvement that FortiManager is addressing."
"FortiMonitor needs to improve its alert system."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"Additionally, there are no AI features in FortiMonitor, which might be an area for enhancement."
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
"We've had some issues previously with the performance of the sensors. We tend to deploy quite a bit of WMI, which is quite processor-intensive, and we've found that that impacts the sensors quite a bit."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"This solution is a good product so far, but I haven't been using it long enough to know how it could be improved."
"PRTG's application monitoring sensor is not strong and could be improved, and I've also had some issues with it crashing during upgrades."
"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."
"Scalability is the only major sticking point for me."
 

Pricing and Cost Advice

"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"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."
"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."
"FortiMonitor's price is very high."
"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."
"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 PRTG Network Monitor is more expensive than other solutions, such as OP Network Manager."
"There is a license to use PRTG Network Monitor and it is annually."
"Our licensing costs are 10,000 euros over three years."
"The licensing fees are billed annually and there are no costs in addition to this."
"The price was pretty good, very competitive."
"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."
"Licenses are very expensive, so I would like to see cheaper licensing."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
