Atera

Atera provides a unified workspace where you can manage your entire IT infrastructure from a single pane of glass. By integrating RMM, PSA, and remote access into one platform, it eliminates the need to toggle between different tools to support your end-users. You can monitor servers, workstations, and networks in real-time while simultaneously managing tickets and billing for your clients or internal departments.

The platform is specifically designed for Managed Service Providers (MSPs) and internal IT teams who need to scale their operations without increasing overhead. Because it uses a unique per-technician pricing model rather than charging per-device, you can grow your managed endpoints infinitely without your costs spiraling out of control. It simplifies complex tasks like patch management and software deployment through a clean, modern interface.
