Senior consultant at Cambridge Institute of Technology

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PRTG Network Monitor can be improved because the dashboard themes feel outdated.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

"It is easy to use and intuitive, which is really important. It does what it says on the box by giving you a visual of the state of what is going on at any one time."

"The most valuable features of PRTG Network Monitor are the threshold notification when certain traffic increases and goes beyond the defined threshold. The up and down status email notifications and other notifications are useful. Additionally, it is user-friendly, and customizable, and there are many features available."

"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."

"To perform your analyses with this solution is easier."

"It is a central solution in terms of how to actually use it. It has a very easy dashboard. Everything is concise. We are able to create custom sensors. For different parts of the business, we have many products across many environments, and it works for everything."

"It has made our infrastructure more reliable."

"PRTG gives us true visibility of the downtime of particular circuit functions, so if a circuit is up but not routing traffic, I will know with this tool and can write a customized script for a sensor to detect specific things."

"Its proactiveness is its most valuable feature. We already know when we come in, in the morning, if a server or site is down, as opposed to someone telling us."

More PRTG Network Monitor pros

"The scanning itself is really the core of the tool, and it's what we're most interested in."

"The level of visibility Tenable provides us, compared to our previous solutions is night and day."

"Tenable is already in the top three risk management solutions and Tenable is already a leader of vulnerability risk management."

"SecurityCenter enables us to find all the vulnerabilities, export that data, prioritize it, and address the highest-risk vulnerabilities."

"The next big one is supportability. In a large enterprise, we have many types of technologies. The technology we previously had didn't even support authentication to a lot of those technologies."

"We can manage everything with only a single console on the Tenable SecurityCenter. We can pull and define the policy. We can perform every task on the Tenable SecurityCenter."

"The first of the valuable features is how easy it is to access all of the information that's gathered from the assessments... With a lot of other technologies, like Rapid7, if you're using Nexpose you effectively have to be a DBA to get some of the lower-level results from the scans. And Qualys wasn't very intuitive."

"Through porting, we can see how the improvement is happening over a period of time. We can see the overall scenario from the last year, where were we were and where we currently stand."

Cons

"Other monitoring tools that I have used are easier to use."

"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."

"Maybe in the future there will be room for improvement, but currently, there is nothing pressing that I can think of"

"It would be nice if it gave us alerts via Gmail or SMS message."

"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."

"I would like to see network mapping."

"Although the reporting module is functional, I feel it is a bit clunky compared to the rest of the interface, and it would benefit from being polished for future use."

"The reporting features look very technical and that can be improved."

More PRTG Network Monitor cons

"When it comes to... dynamic application scanning, I think they are lagging behind the curve. They have a lackluster solution, to the point where I think they need to determine, as a company, whether or not that's a space they even want to play in."

"There are certain circumstances where they may have found a vulnerable service and they just removed the service completely from the device because nobody was using it. There's no way to go into SecurityCenter and mark it, to say, "This is no longer an issue. It doesn't exist anymore." Or, "The risk was accepted for one year, so let's not report it as 'high' until that one year period is done." The handling of operational flow around vulnerability management could be improved."

"In terms of what could be improved, some customers have a problem with SecurityCenter's ticket system. If I want them to assign one of the issues, they may want to assign someone to it or to assign it somewhere else and I may want to break up the ticket."

"For dynamic application scanning, it's a two out of ten."

"One area which is missing is cloud security because there are a lot of configurations. Rapid7 has a product called a DV cloud. I would like to have a similar kind of solution and feature."

Pricing and Cost Advice

"The price of PRTG Network Monitor is reasonable."

"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."

"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 not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us."

"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."

"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."

"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."

More PRTG Network Monitor pricing and cost advice

"Pricing-wise, it's fine. It's not an expensive product. That's not an issue."

"We did a three-year deal where the cost is amortized over the three years. The Elite Support was an additional cost to the standard licensing fees... If you use Security Center, most of the time it is on-premise, so you're going to have some sort of infrastructure to build out and there's going to be a cost associated with that."
