Network monitoring without
the per-sensor pricing.
PRTG is capable, but expensive and complex to license. ACS Monitor gives you the monitoring you need with simple, predictable annual pricing.
No credit card required
Where PRTG gets painful
Capable software, but the licensing model and platform requirements create real friction for growing teams.
Per-sensor pricing that escalates fast
Every device, every interface, every service adds up. A single switch with 48 ports can consume dozens of sensors before you have even started monitoring services.
Complex licensing
Figuring out how many sensors you need before you can even quote a client is a project in itself. Estimate wrong and you are either overpaying or hitting limits mid-deployment.
Windows-only server
Requires a Windows machine to run the core server. That means Windows licensing costs on top of PRTG licensing, plus the overhead of maintaining a Windows server for infrastructure monitoring.
Heavyweight deployment
Significant server resources needed for large installations. As your sensor count grows, so do the CPU, memory, and storage requirements — and the complexity of managing it all.
