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 product has allowed us to have a recording of all business critical network data."
"Time is the biggest thing that I have, and it's given me that back a bit."
"Good compilation of the system's information."
"The real-time monitoring feature in PRTG is invaluable to me"
"The solution has excellent redundant features."
"It is great for service level agreements and can comply fully with internet monitoring or any interface."
"Technical support has been very helpful so far."
"If you're looking from a holistic infrastructure deployment and monitoring perspective, it's a good tool to use and to start with."
"The alerting system is very stable, and it's helpful whenever any sensor is down."
 

Cons

"Customer service was below average and the local value added reseller did not know the product very well."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected."
"I would like to see them take their graphing tools and convert them into a collector so that we can point telemetry to them"
"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."
"They should work on syncing the solution with Gmail."
"The reporting features look very technical and that can be improved."
"The product could be improved by being cross-platform friendly."
"PRTG's documentation could be improved."
"Other monitoring tools that I have used are easier to use."
 

Pricing and Cost Advice

Information not available
"If you are not too sure about it, try the free version. Then, if you like it, you can go to the paid version and roll it out."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"PRTG Network Monitor is not that expensive, so I like it cost-wise. There's no additional cost apart from the standard licensing fees. On a scale of one to five, with one being the cheapest and five being the most expensive, I would rate the cost of PRTG Network Monitor a two."
"It's a cost-efficient tool."
"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."
"We've got the unlimited package... I believe it was around the £15,000 per year mark."
"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 pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
