Verdict
Choose SolarWinds NPM when its NetPath and platform integrations justify element licensing and a quote. Choose PRTG when a measured sensor budget, remote probes, and published entry pricing better fit the network.
On this page
Short answer: For solarwinds vs prtg, choose SolarWinds Network Performance Monitor (NPM) when its NetPath view and SolarWinds Platform integrations justify a quoted, element-based license. Choose PRTG Network Monitor when you can count the sensors you need and want a published subscription price. Both require a self-hosted core; their license units and path tools are different, so compare them against the same network inventory. SolarWinds licensing and Paessler pricing
SolarWinds NPM vs PRTG and the reverse search, PRTG vs SolarWinds NPM, land on the same evaluation: license unit, self-hosted platform requirements and published versus quoted pricing decide the fit either way.
Key takeaways
- SolarWinds NPM counts monitored nodes, interfaces and volumes; PRTG counts sensors. A device count alone cannot produce a fair cost comparison. SolarWinds licensing and Paessler pricing
- PRTG 500 lists at $200 per month paid annually as of September 26, 2026. SolarWinds NPM's product page asks buyers to request a quote rather than publishing a current NPM price.
- SolarWinds NetPath requires supported Windows probe sources; PRTG's remote probes extend collection to other network segments. These are different jobs.
- PRTG auto-discovery builds monitoring objects, while Paessler positions physical Layer 2/3 topology discovery through UVexplorer. Check topology evidence separately from discovery.
- Both products export some historical views, but neither source pack establishes lossless import of the other's configuration and raw time series. SolarWinds report export and PRTG historic data

The entries summarize vendor SolarWinds product, licensing, Platform requirements, Paessler pricing and system requirements. Validate the precise protocol and feature set for your device models in a pilot.
Choose SolarWinds Network Performance Monitor if
- You need to correlate device and interface health with NetPath's measured path from selected Windows sources to services.
- Your team already runs SolarWinds Platform modules and can verify which NPM, NetFlow Traffic Analyzer and Network Configuration Manager capabilities are included in the proposed license.
- You can budget and operate the supported platform and SQL database.
- Procurement can obtain a written NPM quote based on the actual node, interface and volume counts.
Choose PRTG Network Monitor if
- You can size monitoring as sensors and use published PRTG tiers to build an initial budget.
- You want remote probes for checks near branch equipment while keeping a central Windows core.
- You need documented historic sensor exports in CSV or XML for the records selected in the export.
- You can accept Windows for the core server and test whether PRTG's monitoring view meets the topology requirement without a separate mapping product.
Collection and topology: which tells you more about the network?
SolarWinds NPM is stronger when a buyer needs its specific NetPath service-path view. Its product documentation describes device, interface, response-time and packet-loss monitoring. NetPath adds hop-by-hop measurements from a chosen source to a destination. It is a path test, not an inventory map, and its probe requirements constrain where it can run.
PRTG is stronger for a buyer who wants to combine varied checks under a sensor budget with branch collection through remote probes. Its auto-discovery creates devices and sensors from network scans. That is useful for monitoring coverage, but it should not be mistaken for a verified cable-level map. Paessler's network discovery page distinguishes UVexplorer's physical topology capability.
During evaluation, list required devices, interfaces, services and paths. Make each vendor demonstrate data from the same switch, firewall and WAN edge. If a map omits a link, compare it with LLDP/CDP and change records before deciding which display is accurate.
Performance, alerts and incident workflow
Neither product wins for every metric. SolarWinds NPM's license model explicitly covers nodes, interfaces and volumes, which suits teams that want these objects tracked as separate assets. PRTG packages an individual measurement into a sensor, which makes the sensor list and sampling settings central to the design. A useful pilot tests counter gaps, poll intervals, latency sources and report retention with identical devices.
SolarWinds describes thresholds, baselines and dependencies for alerts. PRTG documents sensor-state notification triggers. Neither feature list proves that an on-call team will receive a usable incident. Send the same simulated link failure through both systems, including maintenance suppression, acknowledgment and escalation. Compare the ticket context and time to identify the affected interface, not just the alarm count.
NetPath can add evidence along an application route, while PRTG's remote probes can measure from another network location. Those observations are not interchangeable. Define the incident question first: Is a branch device down, is a service path impaired, or is a link saturated? Then select the collection point that can answer it.
Deployment, security and remote sites
PRTG has the lighter documented core stack: its requirements center on a supported Windows machine for the core server. SolarWinds NPM uses the SolarWinds Platform and supported SQL Server, so the database and platform sizing are separate operational tasks. This is a deployment comparison, not a measured installation-time result.
For remote sites, PRTG remote probes collect checks from locations with access to targets. SolarWinds supports additional polling architecture, while NetPath probes are selected Windows measurement sources. Do not buy a NetPath probe expecting it to replace a polling engine or a PRTG remote probe. Test firewall rules, credential scope, probe-to-core connectivity and behavior during a WAN outage.
Security controls require configuration in either environment. Document service-account privileges, SNMPv3 support on your equipment, admin roles, backup, patch ownership and audit-log export. The SolarWinds Platform requirements and PRTG requirements establish host prerequisites; they do not establish that an installed environment is hardened.
SolarWinds NPM vs PRTG pricing
PRTG has a published entry rate; SolarWinds NPM needs a quote. The Paessler pricing page, checked September 26, 2026, lists PRTG 500 at $200 monthly, paid annually. That implies $2,400 over 12 months at the listed rate before any taxes or contract-specific terms. SolarWinds' NPM page offers a 30-day trial and quote request but no current public NPM list price. A dollar-for-dollar winner cannot be calculated from those pages.
| Environment size | SolarWinds NPM input | PRTG input |
|---|---|---|
| 10 devices | Count monitored nodes, interfaces and volumes; request matching quote | Count every required sensor, not simply the 10 devices |
| 50 devices | Repeat element count including high-port switches | Repeat sensor count including per-port and service checks |
| 250 devices | Include platform, SQL, any additional modules and support | Check whether one published sensor tier covers the calculated checks and probe design |
The table is a counting worksheet, not an estimated price. For example, a switch with many monitored ports can add many NPM interfaces; the same switch can consume many PRTG sensors if each port receives a check. Which grows faster depends on the monitoring policy, not the device label. Confirm NetFlow, network configuration management, failover and support on each proposed order; the base products and add-ons do not have identical entitlements.
The fine print compared
| Decision point | SolarWinds NPM | PRTG Network Monitor |
|---|---|---|
| Path viewpoint | NetPath needs supported Windows source machines | Remote probe supplies remote collection; test path sensors separately |
| Flow detail | NetPath conversation detail depends on NTA integration | Flow checks consume licensed sensors |
| Physical topology | Validate map evidence and refresh in a pilot | UVexplorer is positioned for physical Layer 2/3 discovery |
| Host/database | SolarWinds Platform plus supported SQL Server | Windows core, with PRTG's own data storage design |
| Support | Obtain contract-specific response terms from SolarWinds | Compare Paessler's published support plans and chosen entitlement |
| Trial | 30 days | 30 days, then limited freeware |
The distinctions make a pilot scope more precise. Put at least one high-interface switch, one branch, one critical service path and one noisy alert in both trials. If topology or flow analysis is a purchase reason, demand that the quote identify the exact module or separate product providing it.
Security record compared
Both products require current-version checks and maintenance. SolarWinds publishes release notes and security advisories. Paessler publishes PRTG release history and a 2026 fixed-version notice. An advisory is evidence to verify the installed version, not evidence that a current deployment is compromised.
| Check | SolarWinds NPM | PRTG Network Monitor |
|---|---|---|
| Current patches | Match installed Platform and NPM build to vendor advisories and release notes | Match core and probe build to Paessler advisories and release history |
| Historical incident | CISA's December 2020 Orion alert concerns affected historical Orion versions and requires dated context | Reviewed Paessler source pack includes a 2026 vulnerability notice with fixed-version guidance |
| Independent current audit | Review the vendor's current trust materials and scope; no like-for-like independent audit conclusion established here | Review vendor security materials and scope; no like-for-like independent audit conclusion established here |
Ask each vendor for the current security documentation relevant to the exact deployment. For either self-hosted system, patch cadence, admin access, backup isolation and network exposure are buyer-controlled decisions.
Switching between SolarWinds NPM and PRTG
There is no verified one-click, lossless NPM-to-PRTG or PRTG-to-NPM migration path in the reviewed official material. SolarWinds documents report export, while Paessler documents historic sensor data exports to CSV or XML. A report file and a time-series import are different things. Treat alarm rules, dependency maps, device credentials and dashboards as rebuild work until a pilot proves otherwise.
Before switching, export an inventory with stable device identifiers, collect a representative month of metrics and alarms, and write down poll intervals and thresholds. Recreate a small pilot group in the destination product while the old system remains active. Compare gaps, units and timestamps, then transfer alert ownership gradually. Keep immutable copies of the exported reports for audit requirements even if the new system cannot import them.
Which to pick for your scenario
| Scenario | Better starting candidate | Deciding check |
|---|---|---|
| Existing SolarWinds Platform estate | SolarWinds NPM | Price the incremental NPM entitlement and SQL capacity |
| Need published starting subscription | PRTG Network Monitor | Count sensors for the real device and service policy |
| NetPath service-path investigation | SolarWinds NPM | Place supported Windows probes at the intended source sites |
| Many small branch collection points | PRTG Network Monitor | Pilot remote probe connectivity and administration |
| Physical cable-level topology is mandatory | Neither base product without proof | Validate NPM mapping and price Paessler UVexplorer separately |
| Linux-only monitoring core policy | Neither | Both documented core stacks require Windows |
When neither fits
If the organization will not operate a Windows monitoring core, neither product's documented deployment model satisfies that policy. Start with the network monitoring category and shortlist to find other deployment models.
FAQ
Is PRTG cheaper than SolarWinds NPM?
The PRTG price is public, while current NPM pricing requires a SolarWinds quote. A reliable comparison needs the same device set, NPM element counts and PRTG sensor counts, plus support, modules and host costs. The published starter rate alone cannot establish which production deployment costs less.
Is a PRTG sensor the same as an NPM interface?
Does PRTG have NetPath?
Do both products support a remote-site collector?
PRTG documents remote probes. SolarWinds offers distributed polling architecture, while NetPath probes serve a different path-test role. Size and license the exact collection design with each vendor.
Can historical data move from one to the other?
SolarWinds supports report export, and PRTG supports CSV or XML historic-data export. Neither cited document promises full import into the other product. Test an export and destination import before setting a retirement date.
Bottom line
Select SolarWinds NPM if NetPath and existing SolarWinds Platform operations justify a quoted element license and SQL administration. Select PRTG if a measured sensor count, published entry price and remote probe model better match the estate. Run the same device, path and alert trial in both products, then compare written full-scope quotes. See the network monitoring category or shortlist for the broader choice.
