Paessler PRTG is a well-known infrastructure and network monitoring platform used by IT teams to monitor devices, traffic, servers, applications, databases, cloud resources, and industrial systems. Its main pricing model is based on sensors, not hosts, users, or data ingestion.
Paessler says more than 500,000 users in over 170 countries rely on its monitoring products across IT, OT, and IoT environments. Gartner Peer Insights also lists Paessler PRTG in the Infrastructure Monitoring Tools category with a 4.5 out of 5 rating from 829 reviews as of the current listing.
This Paessler PRTG Pricing & Review guide explains how PRTG pricing works, what a sensor means, what real-world costs can look like, what users like and dislike, and which alternatives may fit better if your team needs deeper observability, OpenTelemetry, distributed tracing, or cloud-native monitoring.
What Is Paessler PRTG?
Paessler PRTG is a monitoring platform from Paessler GmbH, a German software company founded in 1997. PRTG is mainly used for infrastructure and network monitoring, but it can also monitor servers, applications, cloud services, databases, virtual machines, storage, IoT devices, and OT systems.
PRTG is built around sensors. A sensor is the smallest monitoring unit in PRTG. Paessler explains that one sensor usually monitors one measured value, such as CPU load on a server, free disk space, or traffic on a switch port.
That sensor-based model is important because it affects both monitoring depth and pricing. A single device may only need a few sensors for basic monitoring, but a business-critical device can consume many sensors if you track CPU, memory, disk, traffic, services, application checks, database checks, SSL status, and custom metrics.
What PRTG Monitors
PRTG is strongest in traditional IT infrastructure and network monitoring. It can monitor:
| Area | Examples |
| Network monitoring | Routers, switches, firewalls, bandwidth, traffic, packet loss |
| Server monitoring | Windows, Linux, CPU, memory, disk, services |
| Virtualization | VMware, Hyper-V, virtual hosts, VMs, datastores |
| Cloud monitoring | AWS, Azure, Google Cloud resources |
| Application monitoring | HTTP, APIs, databases, email servers, custom apps |
| Industrial monitoring | OPC UA, Modbus TCP, MQTT |
| Traffic monitoring | SNMP, NetFlow, sFlow, jFlow, IPFIX |
Paessler says PRTG has more than 250 preconfigured sensor types covering network, server, application, virtual environment, IoT, and OT monitoring.
Key Features of Paessler PRTG
PRTG is best known for network monitoring. It helps teams monitor routers, switches, firewalls, access points, load balancers, and other network devices. Teams can track bandwidth usage, traffic flow, latency, uptime, packet loss, and device health.
This makes PRTG useful for IT teams that need a clear view of network availability and performance without building a custom monitoring stack.
PRTG can monitor physical and virtual servers across Windows, Linux, and other environments. Common checks include CPU, memory, disk usage, disk I/O, services, processes, and availability.
For many IT teams, this is enough to catch early signs of resource exhaustion or server failure.
PRTG supports monitoring for cloud resources across AWS, Microsoft Azure, and Google Cloud. This helps teams monitor cloud services alongside on-premises infrastructure from one console.
However, PRTG is still more infrastructure-monitoring-focused than cloud-native observability platforms built around traces, logs, metrics, Kubernetes, and OpenTelemetry.
PRTG includes sensors for HTTP checks, APIs, SQL databases, email servers, and other application-level services. This helps teams confirm that important services are reachable and responding.
It is useful for availability and basic performance monitoring, but it is not the same as deep APM with code-level traces, service maps, flame graphs, and transaction-level debugging.
PRTG supports alerting through email, SMS, push notifications, webhooks, and custom scripts. Teams can configure thresholds, notification triggers, escalation paths, and dependencies.
User reviews often mention alerting and real-time network visibility as major strengths of PRTG. Gartner review snippets also highlight simple real-time network monitoring and easy setup for SNMP and WMI use cases.
PRTG includes auto-discovery to find devices and create sensors based on templates. This helps reduce manual setup work, especially in network-heavy environments.
G2 review summaries also show that users often praise PRTG for ease of setup, auto-discovery, and fast onboarding.
PRTG includes dashboards, maps, custom views, and reports. Teams can create views for network operations, infrastructure health, availability, SLA tracking, and management reporting.
Some users like the visibility PRTG provides, while others say the interface can feel overloaded or dated compared with newer tools. Capterra review snippets show both sides: users praise real-time monitoring and broad visibility, but some mention difficult sensor configuration and an interface that can feel overwhelming.
Paessler PRTG Pricing in 2026
Paessler PRTG Network Monitor pricing is based on sensor count. The official pricing page lists five paid Network Monitor tiers: PRTG 500, PRTG 1000, PRTG 2500, PRTG 5000, and PRTG 10000. Prices are shown per month, paid annually.
| Plan | Sensor limit | Approx. device guidance | Official price |
| PRTG 500 | Up to 500 sensors | 50 devices | $200/month paid annually |
| PRTG 1000 | Up to 1,000 sensors | 100 devices | $358/month paid annually |
| PRTG 2500 | Up to 2,500 sensors | 250 devices | $742/month paid annually |
| PRTG 5000 | Up to 5,000 sensors | 500 devices | $1,300/month paid annually |
| PRTG 10000 | Up to 10,000 sensors | 1,000 devices | $1,642/month paid annually |
PRTG Free Edition
PRTG also has a Freeware Edition. Paessler says the Freeware Edition includes up to 100 sensors for about 10 devices. The 30-day trial has unrestricted sensors and devices during the trial period.
The free edition is useful for:
| Use case | Fit |
| Home labs | Good fit |
| Small networks | Good fit if under 100 sensors |
| Evaluation | Good fit |
| Production monitoring | Limited by sensor count |
The main limitation is scale. Since one device can consume multiple sensors, 100 sensors can be used quickly once you monitor more than basic uptime.
What Is Included in PRTG Licensing?
Paessler says all PRTG Network Monitor subscriptions include access to the latest version, new features, security improvements, and email support through the support ticket system.
PRTG pricing is simpler than many modular SaaS observability platforms because teams are not buying separate modules for logs, APM, infrastructure, RUM, or synthetics. But the tradeoff is that pricing depends heavily on sensor planning.
What Does Paessler PRTG Really Cost?
⚠️ Disclaimer
The scenarios below are directional editorial estimates, not official Paessler quotes. Paessler publishes public pricing for PRTG Network Monitor, but final cost can change based on sensor count, device count, monitoring depth, contract terms, taxes, reseller pricing, deployment architecture, and whether the team needs PRTG Enterprise Monitor.
Paessler PRTG is priced by sensors, not by telemetry ingestion. A team producing 5 TB/month of telemetry does not automatically pay for 5 TB in PRTG. The main pricing unit is the sensor. Paessler defines one sensor as one monitored aspect of a device, such as CPU load, disk space, or switch port traffic. Paessler also says teams usually need about 5 to 10 sensors per device, and one sensor per switch port.
Paessler’s public Network Monitor pricing lists PRTG 2500 at $742/month, PRTG 5000 at $1,300/month, and PRTG 10000 at $1,642/month, all paid annually. Paessler maps those tiers roughly to 250, 500, and 1,000 devices.
Pricing Assumptions Used in These Scenarios
These scenarios start at PRTG 2500 because real production environments often monitor more than basic host health. Even a smaller team may track servers, switch ports, firewalls, disks, services, APIs, SSL certificates, databases, cloud resources, and alerting checks.
| Scenario | Infrastructure context | Sensor assumption | Estimated sensors | Relevant PRTG tier | Estimated PRTG cost |
| Small production team | 10 hosts + network/services | ~2,000–2,500 sensors | ~2,500 sensors | PRTG 2500 | ~$742/month |
| Growing team | 50 hosts + wider infra | ~4,000–5,000 sensors | ~5,000 sensors | PRTG 5000 | ~$1,300/month |
| Mid-market team | 250 hosts + complex infra | ~8,000–10,000 sensors | ~10,000 sensors | PRTG 10000 | ~$1,642/month |
These estimates do not include PRTG Enterprise Monitor, internal infrastructure costs, admin time, taxes, reseller pricing, custom sensor development, or professional services.
Workload Assumptions Used for PRTG Estimates
| Team size | Infrastructure context | Telemetry context | PRTG usage assumption | Estimated PRTG cost |
| Small production team | 10 hosts | ~1 TB/month | Deeper production monitoring across hosts, network devices, services, and checks | ~$742/month |
| Growing team | 50 hosts | ~5 TB/month | More infrastructure, service, database, cloud, and network sensors | ~$1,300/month |
| Mid-market team | 250 hosts | ~27 TB/month | Broad infrastructure monitoring near the top public Network Monitor tier | ~$1,642/month |
The telemetry volume is included only for context. For Paessler PRTG, pricing depends on sensors, not GB/month.
Scenario 1: Small Production Team, ~10 Hosts
Situation
A small production team runs around 10 hosts and produces roughly 1 TB of monthly telemetry across logs, traces, and metrics. The team may also monitor network devices, firewalls, service availability, APIs, SSL certificates, cloud resources, databases, and application endpoints.
For Paessler PRTG, the 1 TB/month telemetry estimate does not directly drive the bill. The stronger pricing factor is how many sensors the team creates across every host, interface, disk, service, port, and application check.
Why teams at this stage consider Paessler PRTG
Teams at this stage may consider PRTG because it gives them a mature way to monitor servers, network devices, uptime, bandwidth, service health, and alerts from one platform.
Although Paessler has lower tiers, this scenario starts at PRTG 2500 because production monitoring can quickly grow beyond basic host checks. A team that monitors switch ports, disks, firewalls, SSL certificates, databases, APIs, and service health can consume sensors much faster than expected.
Estimated profile
| Configuration | Detail |
| Infrastructure context | ~10 hosts plus network/services |
| Telemetry context | ~1 TB/month |
| Logs | 720 GB/month |
| Traces/APM | 360 GB/month |
| Metrics | 1 GB/month |
| Estimated PRTG sensors | ~2,500 sensors |
| Pricing basis | Sensor-based monitoring |
| Closest paid tier | PRTG 2500 |
Estimated monthly cost
Disclaimer: This estimate uses Paessler’s public PRTG 2500 price as a planning anchor. A lighter setup may fit into PRTG 500 or PRTG 1000, but this scenario assumes deeper production monitoring rather than basic uptime checks.
| Component | Assumption | Monthly cost |
| PRTG Network Monitor | PRTG 2500 tier | ~$742 |
| Sensor usage | Up to 2,500 sensors | Included |
| Dashboards and reports | Included within platform | Included |
| Alerts and notifications | Included within platform | Included |
| Estimated total | Small production monitoring setup | ~$742/month |
What this scenario shows
For a small production team, PRTG can remain predictable, but the real cost depends on how deeply the team monitors each system. If the team only checks host uptime and a few server metrics, a lower tier may be enough. But if it monitors interfaces, disks, services, SSL certificates, databases, APIs, and cloud resources, the sensor count can rise quickly.
This is why sensor planning matters more than raw host count.
Scenario 2: Growing Team, ~50 Hosts
Situation
A growing team runs around 50 hosts and produces roughly 5 TB of monthly telemetry. The environment now includes more servers, production services, network devices, APIs, databases, cloud resources, and user-facing applications.
For PRTG, the 5 TB/month telemetry volume does not directly affect pricing. The main cost driver is still the total number of sensors.
Why teams at this stage consider Paessler PRTG
At this stage, teams may consider PRTG because they need more reliable infrastructure visibility across servers, networks, firewalls, bandwidth, storage, databases, cloud checks, and service health.
PRTG is attractive because the pricing model is easier to understand than modular observability pricing. But the team still needs to estimate sensor volume carefully before choosing a tier.
Estimated profile
| Configuration | Detail |
| Infrastructure context | ~50 hosts plus wider infrastructure |
| Telemetry context | ~5 TB/month |
| Logs | 3.6 TB/month |
| Traces/APM | 1.8 TB/month |
| Metrics | 5 GB/month |
| Estimated PRTG sensors | ~5,000 sensors |
| Pricing basis | Sensor-based monitoring |
| Closest paid tier | PRTG 5000 |
Estimated monthly cost
Disclaimer: This estimate uses Paessler’s public PRTG 5000 price as a planning anchor. Actual sensor usage can be lower or higher depending on how many interfaces, disks, services, databases, APIs, cloud resources, and custom checks the team monitors.
| Component | Assumption | Monthly cost |
| PRTG Network Monitor | PRTG 5000 tier | ~$1,300 |
| Sensor usage | Up to 5,000 sensors | Included |
| Dashboards and reports | Included within platform | Included |
| Alerts and notifications | Included within platform | Included |
| Estimated total | Growing infrastructure monitoring setup | ~$1,300/month |
What this scenario shows
For a growing team, PRTG pricing is still predictable, but the sensor count can climb fast. A 50-host team may not need 5,000 sensors if it only monitors basic server health. But if the environment includes many network interfaces, firewalls, databases, APIs, services, SSL checks, and cloud resources, the PRTG 5000 tier becomes a more realistic planning point.
The key lesson is that PRTG cost is shaped by monitoring depth, not telemetry volume.
Scenario 3: Mid-Market Team, ~250 Hosts
Situation
A mid-market team runs around 250 hosts and produces roughly 27 TB of monthly telemetry. The environment may include multiple business applications, databases, APIs, queues, cloud services, network devices, firewalls, storage systems, and production dependencies.
At this stage, the team is usually not monitoring only host health. It likely needs dashboards, alert routing, service checks, SLA-style reporting, database monitoring, cloud monitoring, and deeper infrastructure visibility.
Why teams at this stage consider Paessler PRTG
Mid-market teams may consider PRTG because it gives them a mature, sensor-based model for infrastructure and network monitoring. It is especially useful when the main goal is visibility into device health, bandwidth, uptime, server resources, and service availability.
Estimated profile
| Configuration | Detail |
| Infrastructure context | ~250 hosts plus complex infrastructure |
| Telemetry context | ~27 TB/month |
| Logs | 18 TB/month |
| Traces/APM | 9 TB/month |
| Metrics | 25 GB/month |
| Estimated PRTG sensors | ~10,000 sensors |
| Pricing basis | Sensor-based monitoring |
| Closest paid tier | PRTG 10000 |
Estimated monthly cost
Disclaimer: This estimate uses Paessler’s public PRTG 10000 price as a planning anchor. Paessler maps this tier to about 1,000 devices, but a 250-host environment can still reach this tier if monitoring depth is high across ports, services, databases, APIs, cloud resources, and custom checks.
| Component | Assumption | Monthly cost |
| PRTG Network Monitor | PRTG 10000 tier | ~$1,642 |
| Sensor usage | Up to 10,000 sensors | Included |
| Dashboards and reports | Included within platform | Included |
| Alerts and notifications | Included within platform | Included |
| Estimated total | Mid-market infrastructure monitoring setup | ~$1,642/month |
What this scenario shows
At mid-market scale, PRTG can still look affordable compared with many observability platforms, but the real risk is underestimating sensors. A 250-host environment may fit into PRTG 2500 if monitoring is shallow, but it can move toward PRTG 10000 if the team monitors many interfaces, disks, databases, applications, cloud services, APIs, and custom checks.
For larger environments, buyers should also check whether PRTG Enterprise Monitor is a better fit than trying to stretch a standard Network Monitor deployment.
Summary: Estimated Paessler PRTG Monthly Cost
Disclaimer: These are directional planning estimates, not official quotes. Paessler PRTG pricing depends on sensor count, not telemetry volume. Buyers should run a sensor inventory before choosing a license tier.
| Team profile | Estimated sensors | Relevant PRTG tier | Estimated monthly cost | What it means |
| Small production team | ~2,500 sensors | PRTG 2500 | ~$742/month | More realistic for deeper production monitoring |
| Growing team | ~5,000 sensors | PRTG 5000 | ~$1,300/month | Sensor growth comes from services, ports, and checks |
| Mid-market team | ~10,000 sensors | PRTG 10000 | ~$1,642/month | Public tier ceiling before enterprise planning |
Key Buyer Takeaway
Paessler PRTG can be affordable, but buyers should not estimate cost from host count alone. The real question is how many aspects of each device they want to monitor.
A basic server may only need a few sensors. A production system with disks, ports, services, databases, SSL checks, APIs, cloud dependencies, and custom checks can use far more. That is why PRTG cost planning should start with a sensor inventory, not only a device inventory.
What Drives Paessler PRTG Costs?
The biggest cost driver is sensor count. A sensor can monitor one measured value such as CPU load, disk space, switch port traffic, or HTTP availability.
More monitoring depth means more sensors. This is why two companies with the same device count can have very different PRTG costs.
Device count still matters because more devices usually need more sensors. Servers, switches, firewalls, access points, databases, cloud services, and virtual machines all add to sensor usage.
Paessler’s official pricing guidance maps PRTG 500 to about 50 devices and PRTG 10000 to about 1,000 devices.
Basic monitoring may only need ping, CPU, memory, and disk checks. Deeper monitoring can include traffic, disk I/O, services, application availability, database health, SSL certificate checks, custom scripts, and API checks.
This is where costs can grow faster than expected.
Virtual environments can increase sensor usage because teams may monitor hosts, VMs, datastores, clusters, and hypervisor metrics.
Cloud monitoring can also add sensors for compute, storage, databases, load balancers, and managed services.
PRTG supports custom sensors through scripts, REST Custom sensors, SSH script sensors, and HTTP Push Data sensors. This flexibility is useful, but advanced customization may require more technical skill and ongoing maintenance.
Additional Costs Buyers Should Consider
PRTG Network Monitor is commonly deployed on infrastructure controlled by the customer. Buyers should account for server resources, storage, backups, probes, database needs, and high-availability planning.
Large PRTG deployments may need more careful sizing and architecture planning.
PRTG is known for fast setup, but implementation still takes time. Teams need to discover devices, tune sensors, configure alert rules, build dashboards, and create reports.
G2 and Gartner review data both support the idea that users value PRTG’s ease of setup, but large environments still need planning.
Ongoing work can include sensor cleanup, alert tuning, threshold changes, device onboarding, report updates, user access management, and software updates.
TrustRadius review summaries mention that PRTG performance can degrade as sensor counts grow, especially beyond larger sensor counts per installation. This does not mean PRTG cannot scale, but it does mean large buyers should follow Paessler sizing guidance and test the architecture before expanding.
Paessler PRTG User Reviews
PRTG has strong review ratings across major review sites. Gartner Peer Insights lists Paessler PRTG at 4.5/5 from 829 ratings. Gartner also lists 4.6 for Integration & Deployment, 4.6 for Product Capabilities, 4.5 for Evaluation & Contracting, and 4.4 for Service & Support.
Capterra review snippets also show positive feedback around network monitoring, ease of configuration, real-time visibility, and reliability. Some users mention drawbacks such as difficult sensor configuration, interface overload, and reporting/customization limits.
What Users Like About Paessler PRTG

PRTG is widely praised for network device monitoring, SNMP monitoring, traffic visibility, and infrastructure health checks.
The platform supports more than 250 preconfigured sensor types, including network, server, application, virtualization, IoT, and OT sensors.
PRTG’s sensor-based pricing is easier to understand than tools that combine host pricing, user pricing, log ingestion, APM traces, RUM sessions, synthetics, and add-ons.
Users often value PRTG for real-time alerts and proactive issue detection. This is especially useful for IT teams that need to reduce downtime across networks and infrastructure.
What Users Dislike About Paessler PRTG
⚠️ Disclaimer
The following points reflect public user-review themes from review platforms. They should be treated as user feedback, not universal limitations of Paessler PRTG.
The sensor model is simple, but costs can rise when teams add more metrics per device. G2 review summaries note that users like the ease of setup, but many reviews also mention that sensor-based licensing can become costly as environments scale.
Some users say the interface can feel overloaded with information, especially for new users. Capterra review snippets mention this as a downside, although users also say customization can improve readability.
Basic monitoring is straightforward, but custom sensors, scripts, advanced alerts, and complex reports may require more skill.
Large sensor counts can require more careful sizing and architecture. TrustRadius review summaries mention performance concerns as sensor count increases in larger installations.
Paessler PRTG vs Alternatives: How It Compares to Competitors
PRTG remains a strong infrastructure monitoring tool, but it is not always the best fit for every team. Some teams need broader IT operations tools. Others need cloud-native observability, distributed tracing, OpenTelemetry, Kubernetes visibility, or usage-based pricing.
Paessler PRTG vs CubeAPM
PRTG and CubeAPM solve different monitoring problems.
PRTG is strongest for network monitoring, SNMP monitoring, device health, bandwidth monitoring, infrastructure checks, and fast setup. CubeAPM is stronger for modern observability use cases such as OpenTelemetry-native telemetry, logs, metrics, traces, Kubernetes, distributed tracing, RUM, synthetics, and error tracking.
| Category | Paessler PRTG | CubeAPM |
| Primary use case | Network and infrastructure monitoring | Full-stack observability and APM |
| Pricing model | Sensor-based | Usage-based ingestion |
| Starting paid price | $200/month paid annually for 500 sensors | $0.15/GB ingestion |

| Deployment | Network Monitor is customer-managed; hosted option exists | Self-hosted and vendor-managed |
| Strongest area | SNMP, devices, traffic, infra health | OpenTelemetry, traces, logs, metrics, Kubernetes |
CubeAPM lists $0.15/GB ingestion pricing and includes APM, distributed tracing, log management, infrastructure monitoring, RUM, synthetics, error tracking, dashboards, SLOs, RBAC, SSO, MFA, and audit logs on its pricing page.
CubeAPM is not a direct SNMP-first replacement for every PRTG deployment. But it can be a better fit when the team’s main problem is not only “is the device up?” but “why is this service slow, which dependency broke, and how do logs, metrics, and traces connect?”
Paessler PRTG vs SolarWinds Observability
PRTG is often easier to start with for teams that want straightforward network and infrastructure monitoring. SolarWinds is broader across IT operations and network management, especially for teams already using SolarWinds products.
| Category | PRTG | SolarWinds Observability |

Choose PRTG if sensor flexibility and simple infrastructure monitoring are the priority. Choose OpManager if device management and ManageEngine ecosystem fit matter more.
Paessler PRTG vs Dynatrace
PRTG and Dynatrace are very different tools. PRTG is mainly an infrastructure and network monitoring platform. Dynatrace is a full-stack observability platform with APM, distributed tracing, automation, Kubernetes visibility, and AI-assisted root cause analysis.
| Category | PRTG | Dynatrace |
| Best fit | Network and infrastructure monitoring | Enterprise observability |
| APM depth | Limited compared with APM tools | Strong |
| Distributed tracing | Not a core strength | Strong |
| Cloud-native monitoring | Basic to moderate | Strong |
| Cost model | Sensor-based | Platform/usage-based |
Choose PRTG if your main goal is network and infrastructure health. Choose Dynatrace if your team needs deep APM, microservices visibility, Kubernetes monitoring, and automated root cause analysis.
Paessler PRTG vs Datadog
PRTG is more traditional and infrastructure-focused. Datadog is a SaaS observability platform covering infrastructure, logs, APM, RUM, synthetics, security, and cloud-native monitoring.
| Category | PRTG | Datadog |

Choose PRTG if you want simpler network and infrastructure monitoring. Choose Datadog if you need a broad SaaS observability platform and are comfortable managing modular pricing.
Paessler PRTG vs New Relic
PRTG is stronger for infrastructure and network monitoring. New Relic is stronger for APM, telemetry correlation, software performance, and developer workflows.
| Category | PRTG | New Relic |
| Best fit | IT operations | Engineering and DevOps |
| Pricing model | Sensors | Data ingest plus user pricing |
| Network monitoring | Strong | Available, but not the core identity |
| APM | Basic compared with APM platforms | Strong |
| Telemetry correlation | Limited | Strong |
Choose PRTG for network-first monitoring. Choose New Relic if the team needs application performance monitoring, traces, logs, and developer-focused troubleshooting.
Is Paessler PRTG the Right Choice?
PRTG Works Best For
PRTG works well for teams that need reliable monitoring without a long implementation project. The free edition and lower paid tiers make it easier to start small and expand as sensor needs grow.
PRTG is a strong fit for teams monitoring switches, routers, firewalls, bandwidth, traffic, and device health.
Organizations with on-premises servers, virtual machines, storage, and branch networks can get strong value from PRTG.
These environments often need reliable infrastructure visibility, alerts, uptime checks, and reports across many devices. PRTG fits this type of monitoring need well.
PRTG can monitor distributed environments with probes, dashboards, and alerting. Teams should still plan sensor usage carefully across customer sites or locations.
PRTG May Not Be the Right Fit For
PRTG can monitor applications, but it is not the same as a deep APM platform built for traces, service maps, code-level analysis, and distributed transaction debugging.
PRTG is not positioned as an OpenTelemetry-native observability backend. Teams standardizing on OpenTelemetry may prefer tools built around OTLP, traces, logs, and metrics correlation.
PRTG charges by sensors. If your team prefers paying by GB ingested across logs, metrics, and traces, CubeAPM or other usage-based platforms may be easier to map to telemetry volume.
PRTG can support large environments, but large buyers should plan architecture, probes, sensor limits, and enterprise terms carefully before committing.
Conclusion
Paessler PRTG remains a strong monitoring platform in 2026, especially for IT teams focused on network monitoring, infrastructure health, device availability, traffic visibility, alerting, and dashboards.
Its pricing model is easier to understand than many modular observability tools because it is based mainly on sensors. The free edition supports up to 100 sensors, while paid PRTG Network Monitor plans range from $200/month for 500 sensors to $1,642/month for 10,000 sensors, paid annually. Larger environments may need PRTG Enterprise Monitor, which starts at $1,671/month for 10,000 sensors, paid annually.
The main thing buyers must understand is that sensors are not the same as devices. One device can use many sensors, so real-world cost depends on monitoring depth, not just infrastructure size.
PRTG is a strong choice for network and infrastructure monitoring. But teams that need OpenTelemetry-native observability, distributed tracing, Kubernetes monitoring, log correlation, RUM, synthetics, and error tracking should also compare modern observability tools such as CubeAPM, Datadog, Dynatrace, and New Relic.
