End-to-end encrypted file sync & sharing app that lets you store, sync and share files securely and easily.

Save your photos to a secure place, create memos about meetings for your team and access them in shared folders on the go – and be sure that no one can read your files besides you and those who you share with.

Tresorit uses built-in end-to-end encryption with zero-knowledge standards to guarantee the highest level of security. All your files are encrypted on your device before they are uploaded to the cloud, which means no one else can read them besides you, no hackers, no authorities, not even Tresorit’s IT admins.

Cloud storage and encryption at its best

Tresorit is the only cloud storage company that I trust with my personal documents. Day by day there are large-scale attacks on many companies resulting in account usernames, passwords, and data being leaked, scanned and sold to the highest bidder.

Other online storage providers such as Google and Dropbox scan your files and have the ability to see everything you store. I know that Tresorit has my back and that my files can not be accessed by anyone but me.

It has perfect zero-knowledge security, and supports all the security features you would expect, such as 2FA, login notifications, etc... But what makes them really stand out against all the others is their use of client-side encryption, meaning that unlike their competitors, your files are encrypted *before* they're uploaded to the cloud - so no one, not even Tresorit themselves can see your files, because only you hold the key. Syncing across multiple devices also works flawlessly, and file upload speed is very fast. Their encrypted-link sharing features with the options of adding a password and limit the number of downloads is a huge plus. I've used and trusted Tresorit since they launched in 2013 and highly recommend them.

I don’t I have ever written an app review before but I have to for this one! I needed something to secure my work files as well as my personal files, sync across all platforms, and be Hippa compliant. I didn’t need a lot of space or anything like that, but I needed something just for me and my files! This app has it all! It has a free tier that is great my my needs and it even has a feature where you can sync only certain things to certain devices! This is just as good or even better than Dropbox and Box and I have them both! Box I got when they first launched and I got 50 free gigs which is great, but as far as features and things working smoothly, I love this app! I’m glad I found it! Blessings!

Encrypted! Cloud drive that works in Files app

This cloud service is Swiss-based, and cybersecurity professional trusted. It completely integrates with the iOS file system as a cloud drive. This allows you to EDIT Word, Excel, PowerPoint, and all the Apple Office suite of products. The storage does have some cost- but you control the encryption keys, and it syncs the files across desktop and mobile operating systems- flawlessly! This service along with ProtonMail/VPN is really telling that user privacy story through technological empowerment—- encryption based services which the providers have no access to the cryptographic keying material to actually read the data they hold.
