# Ermeo

> Ermeo (rebranded Causeway Field) is a French connected-operator / field-operations SaaS platform that digitizes paper procedures into dynamic, interactive workflows for inspections, maintenance, and interventions. Operators complete pre-built forms on mobile and capture equipment and report data in the field in real time; managers monitor field work from a central console. Ermeo exposes a REST API secured with OAuth 2.0 so customers can connect their information systems (CMMS, MES, EDM) to import and synchronize equipment, forms, and reports.
