Multi-factor authentication for SMBs
MFA for SMBs running Active Directory
Add multi-factor authentication (MFA) to Active Directory at the session level: Windows logon, RDP, VPN, SaaS, UAC, and more. UserLock deploys quickly on top of your existing AD, so a small team can roll it out without disrupting users.

MFA for small business
Enterprise-grade security, without the complexity
Small and medium-sized businesses face the same credential attacks as enterprises, with a fraction of the IT staff. Serious attacks need serious MFA, but it has to fit the way an SMB actually runs.
That's why UserLock runs alongside your existing Active Directory, with minimal management overhead, and stays out of the way of users who need to keep working.
Multi-factor authentication (MFA)
Apply Active Directory MFA across Windows logon, RDP, RD Gateway, RemoteApp, VPN, IIS, SaaS, and UAC. Set policies by connection and session type, so you can ask for MFA more often on remote access, with less strict rules for a workstation login.
Single sign-on (SSO) for Microsoft 365 and SaaS apps
Give users one secure sign-in to Microsoft 365 and other SAML applications with their Active Directory credentials. With UserLock's Active Directory SSO, AD stays the primary identity store to keep things simple.
Access policies based on context
Set contextual access polices and restrictions by time, location, device, and session type, and limit concurrent sessions. When a logon falls outside policy, UserLock blocks it automatically. This helps small IT teams stop credential sharing and block use of stolen credentials.
Real-time session control
See who's logged on, from which machine, and since when. For any suspicious activity, you can take action right from the console. UserLock's session management allows IT lock, log off, or block any suspicious session remotely.
Logon reports for audits and insurers
Native Windows auditing makes it hard to see the full picture. UserLock centralizes every logon event, so you can investigate an incident, create event reporting for an auditor, or show your cyber insurer what access controls are in place in a few clicks.
Why SMBs choose UserLock for multi-factor authentication
Stop credential misuse from outside and inside
Stolen and shared credentials drive both external attacks and insider threats. MFA and session controls at the logon make sure a valid password alone is never enough to get in.
Meet requirements for cyber insurance and compliance
Cybersecurity compliance frameworks such as NIS2, HIPAA, PCI DSS, and CMMC ask for the same thing: access that is identifiable, controlled, and audited. UserLock gives you the control and the reports to prove it.
Protect every account, not just admins
In an SMB, most regular users are just a few lateral movements away from something sensitive. UserLock lets you protect every account, not only privileged access.
MFA and access management that a small IT team can deploy and run
Limited IT overhead
UserLock installs on a Windows server and works alongside your existing Active Directory. There's no new directory to build, and policies reuse the groups and OUs you already have.
Easy adoption for users
Users enroll with up to two approved MFA methods. IT decides when MFA applies, so users see a prompt only when the context calls for it. That means fewer helpdesk tickets and less pushback.
SMB security: The challenge to secure SMBs (small and medium-sized businesses)
SMBs and the MSPs serving them face a challenge: SMB security needs to be just as effective as enterprise-level software, but the tech needs to be easy enough for one person to implement and manage.

The Association Tutélaire des Vosges (ATV), a French non-profit supporting adults under legal guardianship, uses UserLock to automate time-based access controls and secure remote connections. The result: simpler compliance and stronger protection for a hybrid workforce.
