Picture an IT lead who inherited three offices, no documentation, and a closet full of switches labelled in someone else’s handwriting. What they need first is a map: what is connected to what, which firmware is running, and a backup of every config before anything changes. Now picture a different lead, whose network is well understood but whose outages keep coming from a full disk on the ERP server or an expired certificate. Auvik is built for the first person. PRTG is built for the second. Plenty of teams are a bit of both, which is why this comparison comes up so often.
At a glance
| Auvik | PRTG | |
|---|---|---|
| Vendor | Auvik Networks | Paessler |
| Delivery | SaaS; lightweight collector on site | Commercial subscription: self-hosted core server on Windows, or PRTG Hosted Monitor with probes on site |
| License unit | Billable network devices (switches, routers, firewalls and similar infrastructure), usually monthly | Sensors, in fixed tiers, annual subscription |
| Primary focus | Network infrastructure: discovery, topology, config, traffic | Everything with an IP: network, servers, apps, websites, environment sensors |
| Topology mapping | Automatic, continuously updated L2/L3 map; a core strength | Maps are mainly dashboards you design; automatic topology is not its strength |
| Config backup and change tracking | Included for supported devices | Not a core feature |
| Server and application monitoring | Limited; not its purpose | Extensive (WMI, SSH, databases, HTTP, hypervisors) |
| Flow / traffic analysis | Traffic insights in the higher tier | Flow sensors included |
| Multi-tenant for MSPs | Built in | Possible with groups and permissions; less purpose-built |
| Trial | 14 days at the time of writing | Full-featured trial (30 days on the self-hosted edition at the time of writing) |
Discovery and the map
Auvik’s headline trick is the map. Once the collector has SNMP credentials, it walks LLDP/CDP neighbors, ARP and MAC tables and draws a live topology that updates as things change. On a network with no documentation, that alone can justify the subscription. On a typical 60-device office, that process can produce a usable map within the first hour.
PRTG discovers devices and creates sensors automatically, but its maps are primarily dashboards you design: drag devices onto a background, add status icons and graphs. They look great on a NOC screen, yet they reflect what you drew, not what the network is doing. If topology awareness is a must-have, Auvik wins clearly.
Configuration management
Auvik backs up running configurations from supported switches, routers and firewalls, keeps history and shows what changed and when. For MSPs and teams under change-control rules, that feature is often the reason they buy.
PRTG does not position itself as a config management tool. You can watch for changes indirectly, but if you need versioned backups you would pair it with a separate tool.
Beyond the network
Here the balance flips. PRTG’s sensor library covers Windows and Linux servers, SQL databases, Exchange and Microsoft 365 checks, VMware and Hyper-V hosts, web transactions, SSL expiry, UPS units and temperature probes. A single PRTG license can be the only monitoring tool a 200-person company needs.
Auvik tells you the switch port facing the ERP server is saturated, but not that the ERP service stopped. Teams that choose Auvik usually pair it with an RMM such as NinjaOne or a server monitor, and that second subscription belongs in the cost comparison.
Pricing shape
Auvik bills per network infrastructure device, so servers and workstations do not add to the Auvik bill. That keeps it predictable for networks with lots of endpoints but relatively few switches. Check how the quote treats access points and other edge devices, as tier and packaging details change.
PRTG bills by sensor, across whatever you monitor. A network-only deployment might be similar in cost to Auvik; a deployment that also covers servers and apps replaces a second tool. Our pricing models guide compares per-network-device and per-sensor licensing on the same hypothetical 60- and 600-device networks, and the sensor estimation guide helps you size PRTG before you ask for a quote.
Operations and hosting
Auvik is pure SaaS: no server to patch, updates arrive automatically, and the collector is a small service on a Windows or Linux machine or VM. PRTG gives you a choice. Self-host the core if you need data to stay on premises, or use PRTG Hosted Monitor if you want Paessler to run it. Either way, remote probes handle sites the core cannot reach.
Verdict
Pick Auvik if:
- Your pain is the network itself: undocumented topology, config drift, change tracking.
- You are an MSP managing many client networks and want multi-tenancy built in.
- You already have (or plan) an RMM or server monitor for endpoints and applications.
- You want SaaS with no monitoring server to maintain.
Pick PRTG if:
- You want one tool for network, servers, applications and websites.
- Your outages come from services and systems more often than from switches.
- You need the option to keep the monitoring core on premises, or prefer a hosted core through PRTG Hosted Monitor.
- You want to control cost by choosing exactly what to monitor, sensor by sensor.
