Sharing files with customers and vendors is a normal part of business.
The challenge is making sure the right people receive the right information.
Instead of emailing sensitive attachments back and forth, businesses can use controlled SharePoint or OneDrive sharing.
Links can be limited to specific people, set to expire, or restricted from editing.
Sensitive documents may also use encryption or sensitivity labels.
Employees should avoid using personal file-sharing accounts for company information.
Before sharing a file, ask whether the recipient actually needs the entire document or only part of the information.
Secure sharing should be easy enough that employees do not feel the need to work around the system.
The goal is to support collaboration while keeping control of company data.
