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 | PRTG |
|---|---|---|
| Focus | Unified IT, cloud, OT, IoT and physical in one platform | Network and device monitoring for SMB |
| Pricing | One simple price per node per month | Per sensor, you pay for every measurement |
| Published pricing | Per node, every rate on our website | License tiers published; per-sensor model |
| Cost predictability | One flat figure per node, fully predictable | Climbs fast as you monitor more detail |
| OT, IoT and physical | Built in, including CCTV and building systems | Some device polling, not a unified platform |
| Predict and prevent | Built in, flags failures before they cause outages | Threshold based, no prediction |
| Event Intelligence | Built in, one ticket per real issue, faster MTTR | Basic alerting only |
| Data retention | Up to ten years, included | Self hosted, heavy at scale |
| Polling | Matched to each source, with its real update rate shown beside ours | Poll interval only; the source’s true update rate is not shown |
| Multi-tenant and MSP | Native, built in from day one | Weak, often a separate install per client |
| Data sovereignty | Your region (UK, US, Asia), UK owned | Self hosted on premises |
Why teams go looking for a PRTG alternative
It is 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 is not one thing, it is fifty. A modest server is a dozen sensors before you have 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 is not buying a few more sensors, it is stepping the whole licence up a tier, since licences cannot 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 is not 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 is 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 is 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 Event 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 does not 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, with simple, predictable pricing and no surprise charges, set out on our pricing page. 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 pricing is simple and predictable with no surprise charges, 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.
