Ewon Cosy+, Flexy, and Edge
The Big Comparison of Devices and Solutions
From simple remote access to local data services to a scalable Edge-to-Cloud platform
Quick decision:
Cosy+ for simple remote access. Flexy for remote access plus local data capabilities. Edge & Cloud for centralized management, enterprise features, and scalable machine fleets.
Overview
Ewon Cosy+
Compact remote maintenance router for quick and easy VPN remote access to machines and systems via Talk2m. Commissioning is supported by built-in wizards and requires no in-depth IT knowledge.
Ewon Flexy
Modular router for VPN remote access and local data services. Drivers for controllers and field devices enable data acquisition, alarming, logging, visualization, and data provisioning. Interfaces can be customized to the application using expansion cards.
Ewon Edge
Edge & Cloud combines secure VPN remote access, a user-centric approach, and IIoT data connectivity in a scalable Industrial IoT platform. With a choice of various subscription models, the Ewon Cloud can be adapted to current requirements.

5. Typical Use Cases and Selection Recommendations
Ewon Cosy+ – ideal when:
only straightforward remote access is needed for service, commissioning, and troubleshooting, and no local data functions are required.
Ewon Flexy – ideal when:
machine data needs to be captured, recorded, monitored, visualized, or made available locally via OPC UA and MQTT, and traditional interfaces or retrofit options are required.
Ewon Edge – ideal when:
remote access, device and user management, and IIoT data connectivity need to be centrally consolidated, global service processes need to be standardized, or a growing machine fleet needs to be managed.
