Paessler PRTG is an all-in-one IT infrastructure monitoring solution used by more than 500,000 installations worldwide. With a single license, IT teams can monitor their entire infrastructure — networks, servers, applications, cloud services, bandwidth, Wi-Fi, IoT/OT devices, and databases — through a unified web console, desktop app, and mobile apps for iOS and Android.
PRTG uses a sensor-based model: each sensor monitors one specific aspect of a device or service. With over 2,000 pre-configured sensor types covering SNMP, WMI, REST APIs, SSH, Ping, HTTP, NetFlow, IPFIX, Syslog, and more, PRTG deploys in under an hour and delivers immediate visibility across complex, multi-site environments. Paessler has been building monitoring technology for over 25 years from Nuremberg, Germany.
Architecture overview
A central PRTG core server collects, alerts, and reports; remote probes extend monitoring to any location over encrypted TLS; and 2,000+ sensors cover every kind of monitored asset.
Deployment editions
PRTG comes in three editions so you can run it your way — self-hosted, cloud-managed, or at distributed enterprise scale. All three share the same all-in-one feature set.
PRTG Network Monitor
The classic self-hosted edition on your own Windows Server — full control, on your own infrastructure.
PRTG Hosted Monitor
A cloud-managed SaaS edition hosted in Paessler's cloud — no server to maintain, monitoring in minutes.
PRTG Enterprise Monitor
Large-scale distributed monitoring for plants, campuses, and regional offices — deploy locally and scale across sites without corporate dependencies.
Platform features
PRTG ships with a comprehensive feature set in every license — no add-on modules required — covering monitoring, alerting, visualization, reporting, distributed deployments, and AI-assisted intelligence out of the box.
Live dashboards & visualization
PRTG turns raw sensor data into at-a-glance dashboards — colour-coded sensor status (green up, yellow warning, red down, blue paused), live radial gauges, real-time graphs, and a roll-up device tree — on customisable web dashboards and NOC wallboards.

Why PRTG?
Single pane of glass
Monitor your entire IT estate — network, servers, apps, cloud, IoT — from one unified interface. No siloed tools, no jumping between consoles.
Rapid deployment
Install PRTG, point it at your network, and monitoring starts automatically via auto-discovery. Most customers are operational within one hour.
Sensor-based flexibility
Each sensor monitors exactly what you need. Mix and match from 2,000+ types — or write your own — to cover any technology.
Built-in AI intelligence
Anomaly detection, smart recommendations, and sensor deduplication are built directly into PRTG — no separate AI module to license.
Proven at scale
500,000+ installations worldwide across SMBs, enterprises, governments, hospitals, and ISPs. Rated 4.7/5 on Gartner and Spiceworks.
Transparent pricing
Sensor-based licensing means you pay for what you actually monitor — no per-device or per-user fees. Upgrade at any time as you grow.
Common use cases
Enterprise network operations
Monitor routers, switches, firewalls, Wi-Fi, and WAN links with real-time dashboards and instant alerts on availability or performance breaches.
Hybrid cloud monitoring
Extend monitoring across on-premise and cloud (AWS, Azure, GCP) from one PRTG install — REST API sensors connect to cloud APIs without agents.
Industrial / OT monitoring
Monitor ICS, SCADA, and OT assets via Modbus TCP, OPC UA, and EtherNet/IP — visibility into production-critical equipment without disrupting OT.
Healthcare IT monitoring
Ensure availability of EHR systems, medical devices, and clinical networks — the uptime visibility hospitals need to meet strict SLAs.
MSP / multi-client monitoring
Monitor multiple client environments from one platform; role-based access keeps client data separate; APIs enable automation.
Bandwidth & traffic analysis
Use NetFlow, IPFIX, sFlow, and SNMP to find top talkers and anomalies — drill down to application and user level for capacity planning.
