Encrypted, expiring downloads that disappear on schedule.
LockDrop lets you share sensitive files with end‑to‑end encryption, one‑time or time‑boxed links, download caps, and full audit trails—without sending attachments.
Built for security teams, customer support, legal ops, and anyone who needs temporary, controlled access.
Trusted for temporary access by teams shipping sensitive data
Temporary downloads with permanent peace of mind
Set strict policies once, then generate share links in seconds. Every access is encrypted, controlled, and auditable.
End‑to‑end encryption
Encrypt in transit and at rest. Add optional client‑side keys for zero‑knowledge sharing.
Expiring links
Auto‑expire by time, date, or inactivity. Revoke instantly if requirements change.
Access controls
One‑time links, download caps, email verification, passwords, and domain allow‑lists.
Audit trails
Know who accessed what and when. Export logs for compliance, incident response, and reporting.
Large files
Streamed uploads, resumable downloads, and smart chunking for reliable delivery.
API & webhooks
Automate link creation, revocation, and logging. Trigger workflows on download events.
Security model you can explain to auditors
LockDrop is designed for least privilege. Links are scoped to a single file, constrained by time and policy, and can be revoked at any moment.
-
Short‑lived tokens with rotation and scoped permissions.
-
Time‑boxed access + one‑time links and download caps.
-
Event logging for create, view, download, and revoke actions.
Data retention controls, exportable logs, and configurable regions. Integrates with SSO and SCIM for enterprise.
How it works
Share like a link, control like a vault.

Step 3Audit
Track, revoke, and prove
See access events in real time. Revoke instantly. Export audit trails for reviews.
“We replaced ad‑hoc expiring links with actual controls: one‑time downloads plus verification. The audit log alone paid for it.”
“Support used to email attachments. Now we send expiring downloads with caps. Fewer mistakes, faster resolution.”
“One‑time downloads plus instant revocation solved our vendor handoff workflows. It’s simple enough that teams actually use it.”

FAQ
Common questions about encrypted and expiring downloads.
Can I make a link one‑time only? ▾
Yes. Set “max downloads” to 1 (or 0 views after download) and the link becomes unusable after the first successful transfer.
What happens when a link expires? ▾
The token is invalidated and access is denied. You can also revoke links manually at any time.
Do you support zero‑knowledge encryption? ▾
Optional. Teams can require client‑side keys so the server never sees the decrypt key, depending on your workflow needs.
Can I see who downloaded the file? ▾
Yes. You can require verification (email/OTP) and capture audit events including timestamps and IP metadata.
Stop sending attachments. Start sending controlled downloads.
Create your first encrypted expiring link in under 60 seconds.
