Assumption: You are a business owner and you have at least one remote staff.
You’ll want to think about and find a solution for your files at rest (where they are stored) and your files in transit (when they are sent to you).
If you are having someone send you blog posts, it doesn’t really matter if they get lost or stolen. It might matter a little bit, I mean, who steals blog posts? But if you are having your remote working handle accounting, or customer data, you must take actions to protect it.
That turns out to be quite easy. Most modern cloud storage companies (google drive, dropbox) include data encryption. If someone is able to break into Googles servers, they still would not be able to get access to your files, since they will be encrypted. That means, store your files in an encrypted cloud, and take precautions to keep your password safe. Password safety should involve two-factor authentication and a difficult password created and stored in your own password manager.
Protecting data in transit will be more difficult. The quickest, cheapest way is to have your employee password-protect the file she is working on, then upload it to the cloud storage system. That way it will use HTTPS and be encrypted in transit and still maintain a password.
Simple, free, safe(ish). Obviously, you’ll need to trust your cloud provider and your employee. If you can’t trust either, it doesn’t matter if you start spending real money for security.
