Use Case
Secure Microsoft 365 access with Active Directory identities
Enforce secure Microsoft 365 access with access controls at the AD authentication level. With UserLock, apply identity-based access security for Microsoft 365 using your existing Active Directory (AD) setup. No need to move identity to Entra ID, juggle multiple tools, or add complexity.
The Microsoft 365 security gap for on-prem AD
For most organizations, Microsoft 365 is at the core of day-to-day work. But for IT teams with infrastructure built around on-premises AD, MS 365 security is an uphill battle.
Microsoft doesn’t support conditional access with the on-prem AD identity. AD security defaults don’t offer two-factor authentication, period. And Microsoft Defender or third-party authentication apps require an Entra ID tenant. Plus, bolting on complex tools often leads to inconsistent policies, confused users, and added cost.
Relying on Microsoft’s cloud-native identity security solutions can:
Add complexity with multiple identities, directories, and MFA systems
Create blind spots between on-prem and cloud services
Require high-costs licenses costs like Microsoft Entra ID P1 / P2
How UserLock secures Microsoft 365 access without identity rewiring
Federate authentication for on-prem AD identities to secure access to Microsoft 365 and SaaS apps. With UserLock single sign-on (SSO), apply multi-factor authentication (MFA) and context-based access controls. No need to ask users to sign in again or change directories.

Enforce MFA for Microsoft 365 using AD credentials
Apply Active Directory MFA for Office 365 and Exchange Online logins. No need for a cloud-based identity provider (IdP). Enforce MFA policies granularly by AD user, group, and OU, and set different MFA prompt frequency by session type.
)
)
Combine MFA with SSO
Implement single sign-on (SSO) to extend strong authentication and access controls to SaaS access. Users authenticate once at the Windows login, and UserLock SSO federates authentication to MS 365 and other SaaS access.

)
Apply context-based controls
Set login restrictions based on users and devices, location, time, and session type, before users access cloud services.
)
)
Centralize real-time monitoring and response
Track logins across SaaS and on-prem AD access for compliance and to improve security. Detect suspicious behavior and block sessions or users instantly.

)
Audit and report on MS 365 access
Create personalized reports on all Microsoft 365 access. Prove you have the necessary access controls in place for compliance and cyber insurance requirements.

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