Secure file sharing: match the route to sensitivity
Identify what the file contains and who genuinely needs it. A public portfolio sample and a private customer export require different handling. Use the client’s approved sharing system and review its documented controls. Do not assume any cloud folder is acceptable simply because the link is convenient or because another service has strong privacy terms.
Limit access deliberately
Use named recipients and suitable permissions where supported. Check whether a link permits forwarding, downloading or editing. An expiry setting can help but does not recall copies already obtained. Avoid granting an entire workspace access when one collaborator needs one document. Record who owns the file and who can manage access after the engagement ends.
Verify the recipient
Confirm addresses and changes through a known route before sending sensitive material. Be cautious about urgent requests to resend records to a new account. Never include passwords or verification codes in ordinary shared documents. Use appropriate account security, including strong credentials and supported MFA. Access controls are less useful if the recipient account is compromised.
Keep versions and retention understandable
Label final files, preserve required originals and remove temporary copies according to policy. Avoid sending several contradictory versions without explaining which is approved. Obtain consent before uploading client content to an AI tool or external converter. Retention and legal obligations vary; do not delete records merely to make a handover folder appear tidy.
Close access at handover
Confirm that the client can use the agreed files and revoke contractor access no longer required. Review shared links and connected applications. A secure-sharing process includes preparation, delivery and offboarding, not just encryption in transit. It reduces avoidable exposure but cannot guarantee that an authorized recipient will never copy or misuse the information.
