Malware-scanned uploads before media delivery

File delivery starts with ingest policy, so SteadyLink tracks transfer, finalization, metadata extraction, and scanning as separate states instead of treating every completed upload as safe.

The problem

An upload reaching storage does not prove that its content is safe, correctly typed, or allowed by a product's file policy.

The SteadyLink model

SteadyLink validates declared and detected types, applies bucket policy, scans uploaded bytes, and can require a clean result before the file is deliverable.

How it works

Upload lifecycle

uploading  →  finalizing  →  scanning  →  clean

1
Create an upload session
Declare the filename, type, size, destination, and workspace policy.
2
Transfer the file
Send the file through a short-lived, authorized upload session.
3
Finalize and scan
SteadyLink records the revision, extracts metadata, and publishes the scan result.

Stable asset URLs

Give each media asset one permanent delivery URL, then replace the underlying file and retain every revision without breaking apps, sites, emails, or embeds.
