DIDI Chart is the safest bridge between the online world and your offline ECDIS system –
a specially developed security module that decouples and secures digital data flows.

Built on Secure Receive technology, it delivers ENC updates automatically —
a encrypted, controlled, verified, and isolated manner.
Thanks to strict separation, no ports are opened and no return path exists.
Your systems stay offline, yet fully up to date.

Online data in. No risk out.

No more copy-pasting and losing files.
No more outdated ECDIS.

Captain, we’ve automated the boring stuff.

How DIDI Chart Handles ENC Updates

1. Vendor Notification

DIDI Cloud receives a notification from the ECDIS vendor — either via email or a secure REST API using OAuth 2.0 — that new ENC data is available.

2. Secure Download

New chart files are automatically downloaded from the vendor’s SFTP server into the DIDI Cloud application.

3. File Integrity Check

Each downloaded file is validated against the provider’s integrity values to ensure data authenticity.

4. Chart Server Sync

The DIDI Chart Server checks in with the cloud every few minutes via REST. If new ENC files are available, they are downloaded immediately.

5. Local Re-Validation

On the DIDI Chart Server, the files are re-validated to confirm successful and secure transfer.

6. ECDIS Provisioning

Validated data is made available to the vessel’s ECDIS via an independent, isolated USB storage — fully automated, secure, and audit-ready.
