Fixing Oversharing links in SharePoint Online

Hi SharePoint Brain Trust, 

We are currently focused on addressing oversharing within our SharePoint environment. Previously, we had "Anyone" links enabled, but we have since upgraded the sharing settings to "Specific users only." However, we still need to remediate items that were previously shared too broadly.

My question to the group is: Are there any native tools available for this task, aside from SharePoint Advanced Management (SAM)? If not, which third-party tools have you used or would you recommend for managing oversharing in SharePoint?

Thank you!
