Excellent worth the money, fast, revocable links

Wanted an application for storage of very important highly personal information. Wanted to be a able to share files temporarily with accountant and financial professionals. Wanted Internet access as well as iPhone access. Face ID feature works well on the iPhone X, and sending a revocable encrypted file link works perfectly fine with Safari. As long as the company doesn’t go bankrupt, I believe it is worth the extra money over its competitors. Uploaded all financial and important personal information as encrypted PDF’s thru macOS’s preview app which are then stored with zero knowledge and can be shared with a password encrypted link, double the safety. 2FA via text works as well perfect.

Good but lacking important features

Looks like my previous, lengthy review got deleted, so I’ll keep this short.

Great for encryption, but a bunch of annoying issues.

- files with /, :, <> characters will not upload.

- Files app integration is counter intuitive if you can’t password protect it - then your files are exposed

- if you try to share a file, such as a pdf, MP3, or video (probably any file type, but these are ones I’ve tried) by creating a link, whoever you send a link to will not be able to open the file on iOS. This is a huge miss.

Dropbox can do all of these things. There’s no reason why a better service such as Tresorit should lack these basic features.

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.
