Why file sharing security matters
File sharing mistakes can expose confidential documents, customer data, passwords, financial files, or internal system information.
Use the right platform
Use approved platforms such as SharePoint, OneDrive, Google Drive, or internal file servers. Avoid personal email, public links, and consumer storage for business data.
Permission best practices
Grant access to groups instead of individuals where possible, avoid everyone links, set expiration dates, review sharing reports, and remove access when projects end.
Protect sensitive files
Use encryption, labels, password protection where appropriate, and avoid storing secrets like API keys or administrator passwords in shared documents.
Audit and cleanup
Schedule regular reviews of external sharing, anonymous links, inactive users, and old project folders.
