A fair comparison of a managed, network-centric cloud platform and Paessler’s self-hosted (or hosted) infrastructure monitor.
PRTG is one of the best-known all-in-one monitoring products. Paessler’s homepage leads with “Complete Infrastructure Control. Deployed Today,” and the product is built so a team can install it and start adding sensors themselves. NMSaaS is a cloud service for network monitoring and management — discovery, performance, configuration backup and change, policy checks, and vulnerability and end-of-life reporting — with setup, upgrades, and integrations handled for you.
Licensing and scale details from Paessler’s site were current on November 11, 2026. Competitor list prices are not quoted here.
| Topic | NMSaaS | Paessler PRTG |
|---|---|---|
| Deployment | Cloud platform with a single on-site agent (Windows or Linux). NMSaaS handles provisioning, installation, and upgrades. | Two official options. PRTG Network Monitor installs the core server and local probe in your network. PRTG Hosted Monitor is hosted by Paessler on AWS; you still install at least one remote probe to monitor a private LAN. |
| Scope | Network-centric: discovery, inventory and mapping, performance, event and fault management, configuration backup and change, policy checks, vulnerability and EoL, and managed integrations (NMLink). | Broad infrastructure monitoring — servers, networks, cloud, applications, databases, and OT — using a large library of sensors (Paessler states more than 250 preconfigured sensor types). |
| Licensing model | No upfront cost and pay-as-you-go. Not licensed on a per-sensor basis. For MSPs, billing can be monthly or quarterly, and you only pay for the features you sell. | Sensor-based subscriptions. Paessler defines a sensor as one monitored aspect of a device and says you usually need about 5–10 sensors per device. Published Network Monitor license tiers run from PRTG 500 to PRTG 10000. A 100-sensor freeware edition is available for the on-premises product. |
| Scale (public guidance) | Monitor and manage from 100 to over 75,000 devices on one platform. Discovery and policy checks for 10,000 devices are described as taking only a few hours. | Paessler recommends PRTG Network Monitor up to 10,000 sensors (about 1,000 devices on their sizing table) and points larger environments to PRTG Enterprise Monitor. PRTG Hosted Monitor is also listed with a 10,000-sensor maximum. |
| Configuration backup and change | Built into the platform: unlimited backups, automatic backup on change, scheduled and automated changes, audit trail, and policy checks. | Configuration backup, side-by-side comparison, and change tracking are described as part of PRTG UVexplorer, which Paessler presents as an addition to a PRTG environment. Paessler does not list UVexplorer pricing on that page and says to contact the team. |
| Who manages the system | NMSaaS engineers handle setup and upgrades. A dedicated success engineer is committed to understanding your network. | On-premises PRTG: you install, size, update, and back up the core server (updates are “done by user”). Hosted Monitor: Paessler manages the core server, updates, and backups; you still configure sensors and probes. |
| Trial | 45-day free trial. | PRTG Network Monitor: 30-day trial with no sensor limit, plus a 100-sensor freeware edition. PRTG Hosted Monitor: 10-day trial, per Paessler's Hosted Monitor FAQ. |
| Pricing | No upfront cost and pay-as-you-go billing — typically a fraction of the cost of buying, hosting, and maintaining on-prem tools. For MSPs, billing can be monthly or quarterly, and you only pay for the features you sell. | PRTG publishes sensor-based subscription pricing on its pricing page; this page does not quote those figures. |
PRTG is a strong choice when you want one tool that watches more than the network — servers, applications, cloud services, and, where you need it, OT — and you are willing to design the sensor layout yourself. Core Network Monitor license tiers are published, there is a freeware edition for small setups, and a 30-day on-premises trial has no sensor cap. Teams that must keep the monitoring server on their own hardware can do that with PRTG Network Monitor. Hosted Monitor is there if you want Paessler to run the core server on AWS instead.
That do-it-yourself model is the point of Paessler’s “Deployed Today” message. It is also the work you take on: choosing sensors, maintaining the core server (unless you use Hosted Monitor), and, if you need topology maps and config backups, adding PRTG UVexplorer.
“The team at NMSaaS made it a turn key set up. They did all the work for us, handed us the keys, and we were good to go.”
— Michael B., Director of Application Security
“Their Services provide the Software maintenance, Cloud database & space maintenance required. This frees our IT Staff to focus on Monitoring the Network and providing diagnostic assistance to other Network Support Teams. NMSaaS Support has always been very responsive, timely, and effective.”
— Chris B., IT Technical Support Specialist
Operating since 2003, our team has delivered solutions to over 200 of the Fortune 1,000. NMSaaS customers include a U.S. state government, a top 10 global bank, a large Midwest state university system, an international MSP serving hundreds of clients, and one of the largest K-12 school systems in the U.S., on the Pacific coast.
A top 10 global bank. A top 10 global bank monitors about 8,000 devices worldwide with NMSaaS for performance, fault, and configuration management. It replaced an outdated, expensive legacy tool that required a large on-site compute footprint — a complex server system the bank had to upgrade and manage — and now runs that work in the cloud. Daily policy checks run on all devices, and NMLink ties incident and inventory information back to ServiceNow, saving a lot of time and keeping a single source of truth.
One of the largest K-12 school systems in the U.S., on the Pacific coast. One of the largest K-12 school systems in the U.S., on the Pacific coast, uses NMSaaS across more than 45,000 devices and 1,500 individual school locations. The platform monitors internet bandwidth usage and KPIs from every device for performance and fault data, and takes a daily backup of every device’s configuration.
PRTG may be a better starting point if you want to monitor servers, applications, and other infrastructure in the same tool as the network; you prefer to install and tune the system yourself; you want published sensor-based license tiers or a 100-sensor freeware edition; or you need the monitoring server to stay on premises.
NMSaaS is usually the better fit if your priority is the network itself — including backups, policy checks, and end-of-life reporting — and you want a cloud service that is set up and maintained for you. It is also the more direct option when device counts go well beyond a typical PRTG Network Monitor license, or when you do not want to run and update a monitoring server.

No. NMSaaS is a cloud service. You install a single on-site agent on Windows or Linux. The agent can connect with an automatic VPN (no firewall changes) or with a simple port-forward to the agent’s private IP. Inventory, maps, dashboards, and reports are used from your web portal.
No. NMSaaS is not licensed or described on a per-sensor basis. It discovers devices and then monitors and manages them on the same platform. Pricing is no upfront cost and pay-as-you-go — typically a fraction of the cost of buying, hosting, and maintaining on-prem tools. For MSPs, billing can be monthly or quarterly, and you only pay for the features you sell.
Yes. Configuration backup and change management are part of the platform, including unlimited backups, automatic backup when a change is detected, and automated changes. Policy checks and an audit trail are available on the same service.
NMSaaS offers a 45-day free trial. For comparison, Paessler publishes a 30-day unlimited trial for PRTG Network Monitor, a 100-sensor freeware edition, and a 10-day trial for PRTG Hosted Monitor.
If you are weighing a self-hosted monitoring server against a managed cloud platform, book a call or start a 45-day free trial and run NMSaaS against your own network.
