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.

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

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

Pros

"Fortinet's customer support is very good."
"The solution helps to see client infrastructure. It has many boxes and blinks green or red when the station goes up or down. We have different domains for the device groups that we monitor."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"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 is 100% stable."
"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"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."
"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"The most valuable features of PRTG Network Monitor are bandwidth utilization, user-friendliness, all past report simple retrievals, and timeout features. Additionally, if the solution does go down it is simple to bring it back."
"We did some research, found PRTG, and I spoke to another company that used it, they really loved it so we went ahead got the free license initially, did a trial, found it absolutely amazing, and then bought it."
"It is very flexible, and we can monitor many aspects of IT as well as ERP and CRM services. It has a very powerful interface and APIs for customization."
"The real-time monitoring and alerting are its most valuable features."
"PRTG Network Monitor has positively impacted my organization; before PRTG Network Monitor, it was very difficult to monitor a wide variety of sensors, but since implementing it, which supports numerous sensor types and protocols, it has become much easier for us to monitor servers, virtual systems, and cloud services to some extent."
"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."
"It is able to satisfy all our requirements in terms of email notifications and specific errors on the devices."
"Network Discovery is a feature that our customers like a lot."
 

Cons

"Additionally, there are no AI features in FortiMonitor, which might be an area for enhancement."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"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."
"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."
"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."
"FortiMonitor's monitoring could be much better. It should be like, in Palo Alto."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"I would like the ability to monitor Cisco IRS devices."
"The only sort of limitation is the actual probes. So, if you don't have enough probes on there, you can over flip them and cause the WMI sensors and SNMP sensors to sort of overload. Sometimes, they might timeout for a minute, but they do come back."
"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."
"The technical support response time is still prolonged, and the resolution can be better."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"There is room for improvement in this solution for the performance and third-party monitoring protocols. They need to be updated to the latest ones."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
 

Pricing and Cost Advice

"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"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."
"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."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"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."
"We are licensed for 2500 endpoints."
"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."
"PRTG Network Monitor is very expensive."
"If you're looking for a cost effective software I’d suggest this product."
"We bought a license for 4000 sensors."
"Licenses are very expensive, so I would like to see cheaper licensing."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."
