This page compares Paessler PRTG Network Monitor with Observability247 on the thing that actually drives cost and effort: how each platform counts your estate. Vendor facts come from Paessler's public pricing page, last checked July 2026.
Observability247 vs PRTG at a glance
| Aspect | Observability247 | Paessler PRTG Network Monitor |
|---|---|---|
| Licensing unit | Per node — a device is a device | Per sensor; Paessler estimates ~10 sensors per device |
| Tiers | Essentials and Advanced, any node count | PRTG 500 / 1000 / 2500 / 5000 / 10000 sensor tiers |
| Published pricing | Per-node prices published, fixable for up to five years | From $200/month (500 sensors) to $1,642/month (10,000), billed annually |
| Growing past a tier | Add nodes at the published per-node price | Upgrade the whole licence to the next tier; licences can't be combined on one server |
| Coverage in one window | Endpoints, core network, applications, OT, IoT and physical (CCTV, building systems) | Broad sensor coverage; strongest on network/SNMP monitoring |
| Predict and prevent | Built in — leading indicators flag failures before they become outages | Threshold and sensor-state alerting |
| Multi-tenancy | Native — built for MSPs and telcos | Not native in PRTG Network Monitor; larger estates pointed to a separate enterprise product |
| Who runs the platform | We do — hosted, maintained, updated | You do — self-hosted Windows server you operate |
| Data retention | Up to ten years included | Limited by your own server and database sizing |
Why teams go looking for a PRTG alternative
It's nearly always the sensor arithmetic. A “sensor” in PRTG is one monitored metric or aspect — one port, one interface, one service. A 48-port switch monitored properly isn't one thing, it's fifty. A modest server is a dozen sensors before you've added application checks. Paessler's own guidance assumes roughly ten sensors per device, which means the 500-sensor tier is realistically a fifty-device licence — and when device fifty-one arrives, the fix isn't buying a few more sensors, it's stepping the whole licence up a tier, since licences can't be combined on one instance. Teams also outgrow the operating model: PRTG is a self-hosted Windows deployment you patch and scale yourself, multi-tenancy isn't native to PRTG Network Monitor (Paessler points larger, multi-instance estates to a separate enterprise product), and MSPs in particular end up running an instance per client.
Where PRTG is strong
Credit where due: PRTG is one of the fastest monitoring tools to get value from, the sensor library covers an extraordinary range of kit, SNMP support is excellent, and the all-inclusive licence (every sensor type included, support included) is refreshingly simple at small scale. For a stable estate that fits comfortably inside one tier, with an admin happy to own a Windows server, PRTG is good value — that's exactly why so many teams start there.
Where Observability247 differs
Nodes, not arithmetic. A node is a device — a switch is one node no matter how many ports you monitor on it. Estimating your bill takes one count, growth is linear at the published per-node price, and there's no tier cliff where one new device doubles the licence.
The whole estate, not the network corner. PRTG grew up around network monitoring; Observability247 was built to put endpoints, core network, applications, OT/IoT and the physical layer (CCTV, building systems) in one window from the start — with Ticket Intelligence raising one ticket per real issue, Predict and Prevent flagging failures before they become outages, and context-aware prioritisation on top. What your service desk sees is incidents ranked by business impact, not a wall of sensor states.
Multi-tenant by design. MSPs and telcos run many clients in one platform with proper separation — no instance-per-client sprawl, no per-client server estate.
No server to own. We host, maintain and update the platform, with UK, US or Asia hosting and up to ten years of data retention included — your history doesn't depend on how big you sized a database three years ago.
Pricing compared
PRTG Network Monitor is sold as an annual subscription by sensor tier: $200 per month for 500 sensors, $358 for 1,000, $742 for 2,500, $1,300 for 5,000 and $1,642 for 10,000, billed annually, as published July 2026 — with Paessler estimating around ten sensors per device. In node terms, that makes the tiers roughly 50, 100, 250, 500 and 1,000 devices. Observability247 prices per node in two editions, with prices published openly on our pricing page and the option to fix them for up to five years. Count your devices once and you have your number.

Migrating from PRTG
One: turn your sensor inventory back into a device list — divide by Paessler's own ten-to-one guidance for a first estimate, then let us scan the estate for the real count. Two: run in parallel for a couple of weeks; both platforms lean on SNMP, WMI and APIs, so there are no agents to unpick. Three: map sensor-level alerts into ticket rules — most estates find hundreds of sensor alarms collapse into a much shorter list of incidents once correlation is applied. Four: retire the PRTG server. MSPs migrating multiple client instances can consolidate them into one multi-tenant platform as part of onboarding.
Frequently asked questions
How do PRTG sensors map to Observability247 nodes?
Roughly ten to one, using Paessler's own estimate of about ten sensors per device. A PRTG 500 licence typically covers around fifty devices — which would be about fifty nodes here, priced at the published per-node rate.
Do I have to maintain and update the system?
No. PRTG is self-hosted software you run on your own Windows server; Observability247 is hosted, maintained and updated by us.
What happens when my estate grows?
You add nodes at the published per-node price. There are no sensor-tier cliffs, and prices can be fixed for up to five years, so growth is a line on a spreadsheet rather than a renegotiation.
Can Observability247 monitor the same kit as PRTG?
We support over one hundred vendors across network, servers, cloud, databases and OT/IoT, with SNMP monitoring at the core — see our vendors page, and bring anything unusual to the demo.
