Security

Know what protects your shared files.

ShareFast makes temporary artifact sharing easy, with controls for access and safeguards for viewing uploaded content.

Temporary access by default

New Drops expire after seven days by default. Owners can extend access; admins can extend access or revoke a link. Expiry blocks access; it does not delete stored files.

Optional passcodes

Add a passcode when publishing a Drop. Passcodes are stored as salted hashes, and repeated failed attempts are limited. Successful entry grants temporary browser access.

Consistent access checks

Expired or revoked Drops stop serving the viewer, raw file, packaged assets and exports. Publishing a revision keeps the same link and access policy.

Sandboxed viewing

Uploaded HTML runs in a sandboxed viewer. Raw content also uses a Content Security Policy that restricts network connections, forms and embedded objects.

No public file directory

ShareFast has no public discovery of Drops. File listing requires admin access; signed-in owners can view their own Drops.

Revisions stay intact

Each published revision is immutable. A Drop link points to its current revision, while review annotations stay with the revision they were made on.

Anyone with an active link can open a Drop unless it has a passcode. Send links and passcodes only to intended reviewers. Anonymous uploads remain available, and owner sign-in does not restrict who can view a shared link.
