Proactive monitoring has reduced network downtime and enables rapid incident response

The main benefits PRTG Enterprise Monitor provides for us include helping us respond quickly to network problems. For our virtualization switches, we normally use a different vendor, but I am not in charge of that particular system. I have not really used the pre-configured sensors feature in PRTG. A different team handles reporting. For now, nothing really comes to mind regarding additional functions for PRTG. I think it is good for what we use it for. I cannot really say much about technical support because I have never had a situation where I have to reach out. I would give PRTG Enterprise Monitor a final rating of eight. I would definitely recommend PRTG Enterprise Monitor to other users. I am an end user of the product. I am quite satisfied with the alerting part of PRTG, as it is quite good.

Quotes from Members

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

Pros

"The product has allowed us to have a recording of all business critical network data."

"It provides a vast array of options for dashboard creation and monitoring of the activities within the environment."

"If an event is detected, such as a resource running low on storage or RAM, the product will notify you via email. Upon receiving the notification, action must be taken to address and resolve the issue. The feature I find most effective is its comprehensive nature. It's like having a permanent eye monitoring the network and all its nodes. Instead of manual monitoring, it detects anomalies automatically and alerts us accordingly."

"From a technical perspective, the product's most valuable feature is SNMP, an open standard monitoring protocol that works across various network devices and operating systems, including UNIX and Windows."

"What I really appreciate about PRTG Enterprise Monitor is that it is very easy to set up, especially the configuration, which is not complicated, and it is very straightforward to go in and change things."

"The solution's ability to monitor each and every aspect of our devices, such as memory utilization and port connectivity, is valuable."

"PRTG is good and very easy to use."

"It can identify downtimes and disruptions."

"The product is easy to use and you don't need to have any training. You can use it even if you don't have an IT background."

Cons

"Customer service was below average and the local value added reseller did not know the product very well."

"PRTG Enterprise Monitor should include more functionalities and features that are similar to SolarWinds."

"When it comes to dashboard customization in PRTG Enterprise Monitor, there are not too many options, and I think that would not be a strong point for PRTG, but for our use cases, we do not really need that kind of customization."

"There is no unified monitoring in PRTG. It needs a lot of improvement in terms of integration."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"The solution could be improved by including a processing monitor, possibly with a language interface like Lua, allowing for writing custom sensors and processing outcomes of inputs."

"The licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"The licensing policy needs to change."
