Userlock
Enforces AD logon policies and records Windows authentication events for audit.
UserLock — Active Directory logon and session control for Windows
Managing where and how users sign in is a common operational problem in Windows estates. Unrestricted logons, shared accounts and remote access make it hard to enforce who is actually using an account. That adds risk for regulated organisations and multi-site operations that need clear audit trails.
UserLock enforces logon and session rules at the Active Directory account level. It limits concurrent logons, restricts permitted workstations and locations, and can block or terminate sessions that violate policy. The product also records authentication events and produces alerts for IT review and investigation.
Where Userlock is used
Prevent shared accounts and reduce concurrent logins across branch offices by enforcing per-account session limits and approved workstation lists. This helps where staff move between sites or use hot-desking setups.
Use UserLock to capture authentication evidence for investigations or compliance checks. It can alert teams to unusual logon patterns and provide audit-ready records without changing core AD authentication.
Suitable environments
Fits medium and large, Windows-centric organisations with Active Directory. Particularly useful for regulated bodies, multi-site networks and businesses with remote or hybrid workers that need tighter session control and auditability.
