ERA Office vs Microsoft 365 (Office)
Microsoft 365 dominates cloud office productivity. ERA Office delivers documents, spreadsheets and presentations with co-editing inside the isolated perimeter.
| Criteria | Competitor | ERA One |
|---|---|---|
| Model | Cloud SaaS (Word, Excel, PPT online) | On-prem ERA Documents, Tables, Presentations |
| Co-editing | Cloud real-time | On-prem co-editing in contour |
| File storage | OneDrive / SharePoint cloud | ERA Drive in customer perimeter |
| Data residency | Microsoft cloud | Customer DC only |
| Air-gap | Not supported | Native offline licensing & updates |
| AI | Copilot cloud | ERA Office AI — local LLM |
| Integration | Teams / Exchange cloud | ERA Communications + Control on same platform |
Summary: Microsoft 365 wins on feature breadth and ecosystem. ERA Office wins when documents must stay inside a sovereign air-gapped contour alongside ERA Communications and Control.
