Separate live drafting from protected milestones
An encrypted archive is not the same as the live collaboration workspace. Define where authors edit, how access is granted, when a milestone is frozen and where plaintext exports can appear.
The supplier uses an approved workspace for drafting, freezes a red-team milestone, encrypts the retained package and removes local exports after confirming the controlled archive and recovery copy.
Run the control in five steps
- 01Choose the approved workspace and accountable owners.
- 02Restrict access by role and remove departed contributors.
- 03Freeze named milestones after color-team or executive approval.
- 04Protect retained copies with an approved encryption method.
- 05Search local, email, download and temporary locations for residue.
Preserve the decision trail
Keep workspace, role list, milestone, source hash, archive path, encryption method, residue check and approver.
Stop and investigate when
- The encrypted archive is treated as the live master.
- Former contributors retain workspace access.
- The only copy is encrypted without tested recovery.
State what this does not prove
Does not replace provider permissions, guaranteed backup, password recovery or enterprise identity management. Solicitation rules, portal identity, contractual safeguards and authorized review remain separate.
Procurement bid security questions
Does encryption manage collaboration roles?
No. Workspace identity and permissions remain separate controls.
Must every draft become a retained milestone?
No. Define meaningful gates and retain according to policy.
