File upload system for an organization, what software to use?

Question

Data storage

We need a file upload system that meets the following conditions:
1. Work from a browser.
2. The client must register (or we will make him) an account, upload files, without the possibility of replacement.
3. We want to see client folders and be able to modify files.
Are there ready-made solutions for such a scenario?

Answer 1

owncloud (file storage with http/https access and authorization) + Samba (to share a folder for access from Windows machines, for example)

Answer 2

You can do all this on crutches: ftp + published web muzzle, which will generate a user with the necessary rights.
It is possible to look at some paid MFT solution.

Answer 3

Synology storage any everything is there

Answer 4

Synology and its private cloud (can't remember the name). If buying a shelf is crushed by a toad, install a virtual machine with xpenology. Their programulina directly finally falls on your requirements
