Performance-wise, PRTG Network Monitor still needs improvement because a large number of SNMPv3 queries reduces tool performance. If PRTG Network Monitor can evolve into agent-level configurations rather than server-level configurations, where you can install the agent on the server and the agent provides the necessary feedback, that would improve the tool. If my company does a large number of SNMPv3 queries, that will reduce server performance, so PRTG recommends not scanning or monitoring a massive amount of SNMPv3. It'll impact performance, including the PRTG Network Monitor performance. Otherwise, it'll reduce performance when you need to monitor it at the server level.

From a security point of view, SNMPv3 monitoring needs to be stronger. Here's an area for improvement in PRTG Network Monitor: my company needs to perform SNMPv3 monitoring, and by default, SNMPv2 is there. Some OEMs may have the feature, but the charges would be huge for such a feature.

The remote probe feature in the tool helps you monitor remote systems or your network, so it's an outstanding feature available in PRTG Network Monitor compared to other OEMs in the market.

It is beneficial because it ultimately gives you visibility from the central server. The remote probe will be deployed at the site remotely, and PRTG Network Monitor will monitor the site and feed all monitoring data to the central server. The company doesn't need to buy an additional license or commercial license. I find this pricing model helpful, mainly because my company has multiple sites here in India, between thirty to forty sites.

Still, PRTG Network Monitor allows up to sixty or eighty remote probes for one server, particularly when you buy the PRTG main server license. Other OEMs in the market will charge you after some time if you have multiple sites distributed within a particular region. Suppose you have four or five locations and deployed the agent other solutions will charge you extra or add commercial charges to your invoice. I like that PRTG Network Monitor is evolving as a product. For example, it's releasing new sensors on the OT, Modbus, and MQTT side, but its most valuable feature is the remote probe.
