How do you collaborate on documents securely?

For us, the biggest change was stopping email attachments altogether. We moved to a shared platform where we can co-edit documents with role-based permissions. It cut down on version confusion and kept files more secure. Two-factor authentication and limited access are must-haves. I found some recommendations on flash3c.com for tools that make collaboration safer, and that’s what we based our setup on. My advice is to pick something that integrates smoothly into your workflow. People adapt faster when the tools feel like a natural upgrade rather than extra work.
