5 tips to share download links securely

Security – 2026-06-14

If you pass on links, you should protect them. Five practical tips so your shared download links don't fall into the wrong hands or to bots.

1. Bundle links in a container instead of an open list

An open link list is easy to copy and quickly harvested by bots. An encrypted container bundles all links under a single address and only releases them after the access check.

2. Protect with password and captcha

A password ensures only the intended recipient gets access. A captcha makes automated harvesting costly. Together they form a simple, effective hurdle against mass harvesting.

3. Limit time and number of accesses

Set an expiry date and an access limit. That way the container is deleted after a chosen deadline or hands out no more links after a certain number of unlocks – ideal for confidential or one-off shares.

4. Use geo and IP rules where it makes sense

If a container is only relevant in certain regions or networks, restrict access via geo and IP rules. This reduces unwanted views and makes sharing more targeted.

5. Post publicly with stealth mode and AutoProtect

If you post links publicly, use stealth mode and AutoProtect: stealth mode shows rejected visitors “not found” instead of “blocked”, and AutoProtect puts an intermediate page with a wait and an invisible proof-of-work in front of every masked link – so the links can't be harvested by a simple script.
