Limiting the amount of object information available to guest users in the tenant, reduces malicious reconnaissance exposure, should a guest account become compromised or be created by an adversary.

Configured: Guest users have limited access.

Not Configured: Guest user settings do not restrict access.

Scoring: Contributes up to 1 point to the Posture Recommendations score.
