Core protections

• Authenticated access with role-based permissions for admins, editors, and viewers.
• Per-sheet sharing controls so access is limited to authorized users.
• Audit logging for key actions such as logins, sharing changes, edits, downloads, and automation activity.

Data controls

• Server-side validation on dates, numbers, emails, dropdowns, and structured fields.
• Attachment access restricted to users with permission to the underlying sheet.
• Shared access can be revoked immediately for both direct members and pending invites.

Operational guidance

• Use strong unique passwords and rotate admin credentials regularly.
• Grant editor access only where editing is truly needed.
• Review shared access and audit logs on a regular cadence.

Platform direction

This deployment is being aligned toward a GLBA-aware operating model with stronger access discipline, cleaner sharing workflows, and tighter governance over stored files and spreadsheet records.
