Secure file sharing with signed, expiring links
Send large originals with links that expire when you decide. Keep files private until you publish, and control exactly who can access what.
The problem
- Email and consumer file-sharing leak links that never expire.
- You need to revoke access and set expiry windows, not hope nobody re-shares.
- Large originals are painful to move and easy to lose track of.
How Outbound helps
Outbound mints HMAC-signed download links with an expiry you control, from minutes to a week. Files stay private as drafts and only become public when you publish, so sensitive originals never leak through a forgotten link. Recipients download directly from the edge — no account, no friction.
What you get
Signed, expiring links
Every download link is cryptographically signed and expires on the schedule you set.
Private by default
Drafts stay private; nothing is public until you explicitly publish it.
Large originals
Move files up to 10 GB and hand off the original without compression or accounts.
Fast, direct delivery
Recipients download from the nearest edge location with no throttling.
The outcome
- Links that expire on your terms

- No accounts for recipients, no leaks
