# Simplify hybrid Active Directory security

_Use Case_

Enforce secure hybrid access by extending strong authentication from the on-premises Active Directory domain to Microsoft 365. With UserLock, hybrid Active Directory (AD) security doesn’t have to mean fragmented access security. Centralize access control for every user, session, and resource without forcing an identity migration or slowing down productivity.

## Why hybrid Active Directory security is hard to get right

Securing a hybrid Active Directory environment means securing logins and enforcing access controls consistently, wherever users sign on, to whatever resources they need. 

Many organizations are moving to the cloud, but most still rely on domain-based infrastructure for core identity services. Tools like Microsoft Entra Connect help sync identities between on-premises and cloud environments.

But the security model often fails when: 

- Users bypass conditional access policies
- Privilege escalations and legacy authentication methods introduce risk
- Microsoft-native tools push toward Microsoft Entra ID-only models that disrupt AD setups

## How UserLock supports secure hybrid access

Unlike cloud-based identity and access management (IAM) solutions, UserLock lets you maintain on-prem domain control.

- No disruption to how users sign in
- No need to rewire your identity architecture
- Fewer tools to manage, pay for, and train for
- More consistent, policy-driven security

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

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

## Comprehensive access security for a modern AD network

### Unify MFA across all access

Enforce multi-factor authentication (MFA) for secure access to hybrid AD resources. Apply MFA granularly by AD user, group, and OU, and adjust frequency by session type.

### Control SaaS access with single sign-on (SSO)

Extend secure on-premises AD identity authentication to SaaS. UserLock SSO federates the on-prem AD identity authentication, bringing SaaS apps under local access policies.

### Apply contextual access policies

Set context-based access controls based on AD users, groups, and OUs. Limit access based on login context such as device, location, IP address, session type, and number of concurrent logins.

### Monitor access and respond to threats in real time

Track all access and access attempts across your hybrid AD environment. Set up alerts for suspicious activity, and block or logoff users remotely.

### Audit access to the hybrid network

Get accurate insights on all AD account access to on-prem and SaaS resources.

### Create reports to prove compliance

Stay audit-ready with centralized logs and reports on access to both on-prem and cloud resources. Simplify routine audits and prove your access controls address hybrid security risks.

## Why IT teams choose UserLock for a hybrid AD environment

#### Centralize MFA and access controls

Verify AD user identities at the credential provider level. Manage one MFA solution for AD identity access to on-prem and SaaS resources.

#### Combine MFA and SSO

Bring access to SaaS apps under IT's control, without rewiring identity infrastructure. Apply MFA to the on-premises AD identity at logon, and extend that strong authentication to SaaS with SAML-based SSO.

#### Built for on-prem and hybrid AD

Bring modern controls to bridge the security gap between SaaS resources and on-premises AD, terminal servers, and legacy apps. Reduce dependency on costly Microsoft Entra ID licensing.

#### Remote access security

Apply the same MFA policies and access controls to Remote Desktop, RDP, VPN, and RemoteApp to control remote access to resources across your hybrid environment.

#### Instant visibility and response

See when an AD user account logs on, from where, and how. Remotely respond to suspicious behavior to block or logoff a user with one click.

#### Simplify compliance

Report on every successful or failed AD user login and access to SaaS apps in tamper-proof, searchable logs. Report on user session history, MFA events, administrator actions, and more to satisfy cyber-insurance and regulatory requirements.
