How to Review Cybersecurity Practices Before Sharing Client Files With a Subcontractor

A subcontractor may need access to client materials but may not operate under the same security controls as the primary business. Sharing links can outlast the work or reach unintended recipients.

What to check

Confirm contractual permissions, data sensitivity, subcontractor identity and location, access controls, MFA, storage and retention, onward sharing, incident notification, and end-of-work deletion.

Recommended next step

Share only the minimum required through an approved, logged channel with a named owner and time limit. Review access during the engagement and confirm revocation and data handling when work ends.
