Use Case

Secure Windows logins

Secure Windows logins from unauthorized access during the logon process and beyond. With UserLock, implement multi-factor authentication (MFA), contextual access controls, and real-time monitoring, all without adding complexity.

Where native Windows authentication falls short

Native Windows systems can’t enforce consistent logon rules or detect suspicious access behavior. IT teams need deeper control over who gains access.

You need to control how many sessions users can keep open, and what happens when access looks suspicious.

Every Windows logon represents a potential attack path. Key risks include:

  • Shared or reused Microsoft account credentials across users or systems

  • Insecure remote access (VPN, RDP, unmanaged devices)

  • Security gaps between legacy systems and cloud-based identity platforms

How UserLock secures
Windows logons

Apply access policies at the most critical point of access: the Microsoft Windows logon.

  • Enforce granular MFA

  • Apply contextual access controls

  • Set limits on sessions

  • Block suspicious behavior without disrupting users.

UserLock sits at the Active Directory authentication layer thanks to a custom Windows credential provider. Built for AD, UserLock lets you set access policies by AD user, group, and OU.

It’s easy to use, easy to scale, and keeps IT in control.

Comprehensive Windows logon security

Two factor authentication

Enforce MFA to verify identity

Implement Active Directory multi-factor authentication (MFA) on interactive logons and non-interactive access. Set different MFA policies for different AD users, groups, and OUs, and adjust frequency according to session type.

Single Sign-On

Extend strong authentication to SaaS access

Enable single sign-on (SSO) for AD identities to extend on-prem authentication from local systems to SaaS resources. Users enter their password once at login, complete strong authentication, and gain access to SaaS apps.

Temporary and permanent policies

Apply context-based controls

Enforce contextual logon requirements to limit user account access by location, time, device, and concurrent logins.

Active sessions - Active Directory

Monitor and manage logon sessions

See all Active Directory network access as it happens. Set up alerts to detect and remotely respond to threats.

Report users and session type

Audit protected Windows access

Get accurate insights on all AD account access with tamper-proof, searchable audit logs. 

Simultaneous sessions chart report

Prove compliance

Produce clear reports of who accessed what, when, and from where, no manual logs required.

Why security teams choose
UserLock for Windows logons

Easy to use MFA at
the sign-in screen

Add hardware, TOTP, or push-based MFA at the credential provider level. Verify every interactive and remote logon before a user session starts. 


Context-aware enforcement that AD alone can’t do

Restrict logons by workstation, IP address, time of day, geolocation, or concurrent session count. Policies follow AD users, groups, and OUs, making setup easy and audits clean.

Built for legacy & locked-down environments

Bring modern controls to on-prem AD, terminal servers, and legacy apps. Keep infrastructure costs down. 


Remote access security

Manage MFA policies and session limits across Remote Desktop, RDP, VPN, IIS, and SaaS.

Instant visibility and response

See who logs on, where, and how in real time. Block, log off, or disable an account with one click the moment a session looks risky. 



Auditing and reporting

Capture every successful or failed Windows login in tamper-proof, searchable logs. Report on user session history, MFA events, administrator actions, and more to prove compliance.

  • Strong 2FA and concurrent login restrictions for HIPAA compliance.

    I can’t trust that someone is a legitimate user or administrator just because they were on a computer on-site. Now I can verify who’s using our computers with UserLock.
