Mimecast is a cloud SEG. We are MX on your host. That is the split. We are an email gateway, not a DLP clone and not an archive clone.
| Mimecast | Secure Message | |
|---|---|---|
| Who hosts it | Their cloud SEG | You. MX on your host. |
| Where encryption happens | Their cloud | On your host |
| Where keys live | Their service | On the host you run |
| Recipient | Their path | Opens a link, enters a one-time code. No account. |
