Secure data transfer

Send data files to GraniteCore Technologies.

This portal lets invited organizations deliver CSV, ZIP and documentation files directly to GraniteCore's private cloud storage over HTTPS. Access requires an invitation link and an access code issued by GraniteCore for a specific project and dataset.

How it works

  1. Open the invitation link you received. It carries your invitation token.
  2. Enter the access code that was provided to you separately.
  3. Choose the file. Large files are sent in pieces and resume automatically after a network hiccup.
  4. Keep the receipt. It lists the file's SHA-256 fingerprint and the time of delivery.

What happens to your file

Files travel straight from your browser to a private storage account using a short-lived, single-file authorization. Nothing is shared publicly and no account credentials are exchanged.

Every file is held in quarantine, scanned for malware, verified against its declared size and fingerprint, and only then released to the GraniteCore team working on your project. Files are retained for the period agreed for the project and then deleted.
