Prevent unauthorized access with a free toolkit
Ad-hoc access requests, nested groups, and inherited rights can leave file servers exposed to risk. Analyze NTFS Access Control Lists (ACLs) to achieve least privilege.
See exactly who has access to what
Get one view of every explicit and inherited permission across your Windows file servers mapped by user, group, and folder. Filter by department or sensitivity to spot overexposed data before it becomes a breach.
Fix excessive permissions before they’re a problem
Flag accounts with more access than their role requires, then revoke unused or inherited rights in a few clicks. Close open shares, like Everyone or Authenticated Users, that leave sensitive folders exposed.
Prove least privilege with audit-ready reports
Generate reports mapped to GDPR, HIPAA, PCI DSS, and SOX in a click. Netwrix Auditor users cut their audit prep time by up to 85%, so you spend less time building evidence and more time closing gaps.
