ShareSecure vs Tresorit

Updated October 27, 2026

Tresorit and ShareSecure both encrypt files end to end, so neither service can read what you send. They differ in size limits, in what you can control after sending, and in openness. Here's an honest comparison of Tresorit's free sharing tool, Tresorit Send, with ShareSecure, as of October 2026.

	ShareSecure	Tresorit Send (free)
End-to-end encryption	Yes, on by default	Yes
Biggest upload	10 MB on the website, 100 MB with the desktop app on your own computer	5 GB, up to 100 files
How long links last	1 hour to 10 days, your choice	7 days
Downloads	View-only by default; you choose. Links can work just once.	Up to 10 downloads per file
What you give to send	A username and password. No email.	Your email address
Passcode on a link	Optional	Optional
Open source, run it yourself	Yes (MIT), with a desktop app and Docker	No

ShareSecure also opens PDFs, Word files, images, video and ZIPs in the browser, and has request links anyone can send you files through. Tresorit's paid plans add more; see its pricing.

When Tresorit is the better choice

For big files, Tresorit Send's 5 GB limit is far beyond ShareSecure's website. And if your company needs a full encrypted cloud drive with sync, admin consoles and compliance paperwork, Tresorit's paid business plans are built for that, and ShareSecure isn't a drive.

When ShareSecure is the better choice

You want control after sending: view-only links, links that work once, passcodes, and expiry from an hour up.
You want people to read it, not download it: documents open in the browser, and a watermark can show who opened them.
You don't want to hand over an email address, or link your shares to your account: ShareSecure uploads with anonymous tokens, so even its own server can't tell who shared what.
You want to check the code, or run it yourself. Everything is open source, and the website can be checked against the code with one command.
