The best multi-factor authentication (MFA) solutions for Active Directory

The Best Multi-factor Authentication (MFA) Solutions for Active Directory

Active Directory (AD) is a widely used authentication and authorization system that provides access management for corporate networks. But, as cyberattacks become increasingly sophisticated and target user login credentials as the easiest point of entry, there is a critical need for strong authentication measures to increase protection.

Multi-factor authentication (MFA) adds a layer of security to the login process, requiring users to provide two or more forms of authentication to gain access. Many industries, compliance regulations, and cyber liability insurance providers now require MFA as standard.

To work efficiently, today’s on-premise and hybrid AD environments require an MFA solution that is convenient and robust. It should protect system access while allowing admins and employees to remain productive. The best MFA solutions will also provide granular configurations to best fit each organization’s needs.

To help you find the right MFA product for your organization, we highlight some of the best MFA for Active Directory environments below. For each, we’ll see their features, benefits, and any potential downsides.

UserLock Multi-factor Authentication (MFA)

The UserLock MFA solution offers a straightforward way to implement strong MFA measures across on-premise and hybrid Active Directory environments. Administrators can choose to enable UserLock MFA for VPN, Windows login, RDP, RD Gateway, IIS, and across SaaS and cloud applications.

UserLock also supports implementing MFA with authenticator applications, such as Microsoft or Google Authenticator, as well as hardware tokens like YubiKey and Token2.

Using time-based and HMAC-based one-time passwords (TOTP, HOTP), UserLock helps admins verify the identity of their Active Directory accounts and provide secure access to corporate networks.

Benefits of UserLock for MFA

Utilizing UserLock to manage MFA brings many advantages.

  1. UserLock can be deployed alongside an existing on-premise Active Directory. By integrating seamlessly with an existing on-premise AD, UserLock makes it simple to scale MFA across an organization.
  2. UserLock is designed for both on-premise and hybrid AD environments. With UserLock, it’s possible to implement MFA across various platforms. Administrators can also enable MFA on any computer or device with AD membership.
  3. UserLock enables granular MFA customizations. The best MFA solutions allow administrators to configure MFA to avoid “authentication fatigue.” With its granular MFA, UserLock allows each organization to define its own MFA rules and requirements. This helps avoid a frustrating end-user experience and loss in productivity, while promoting increased security.
  4. UserLock provides contextual access controls. Different organizations have different authentication and user logon requirements. UserLock allows each to define its own access policies through contextual access management. Any authentication attempt that does not meet the requirements is then blocked.
  5.  UserLock supports multiple MFA methods. ​​UserLock works seamlessly alongside multiple MFA options like push notification services, authenticator apps, and hardware tokens.
  6. UserLock can provide MFA to users without internet access. The best MFA options also cater to situations when users are offline. With secured on-premise hosting, UserLock’s offline-available MFA helps secure systems even without an internet connection.
  7. UserLock can prompt remote users for MFA. With remote working and widespread teams, it’s more crucial than ever to protect users outside of the corporate LAN or VPN. With UserLock Anywhere, organizations can require MFA even when the user doesn’t connect to the network.
  8. UserLock can enable MFA on all devices with AD membership or standalone terminal servers. Adding UserLock to new computers and devices is straightforward. UserLock can automatically detect new endpoints, implementing the organization’s MFA requirements straight away.
  9. UserLock can apply MFA across various connection types. It’s possible to implement UserLock MFA on IIS, RDP, RD Gateway, and VPN connections, among others.
  10. UserLock MFA recovery codes can be used as a one-time password (OTP). UserLock provides a number of backup recovery codes for enrolled users. Should a user need to, they can provide an OTP to pass organizational MFA requirements and access the system.
  11. UserLock provides simple MFA enrollment. With UserLock, new users can enroll in corporate MFA requirements quickly and efficiently. IT admins can also choose between adding new users themselves or enabling self-enrollment.

Popular MFA Providers vs UserLock

How does UserLock compare with some of the other MFA solutions on the market today?

Duo by Cisco

Cisco Duo Security is a multi-factor authentication solution that validates user identities through a mobile app and other MFA methods. Users can use the app to confirm or deny a login attempt, or provide a passcode. Overall, Duo is a popular and strong authentication option with potential benefits and drawbacks for organizations.

  • Duo Security is a cloud-based MFA solution that can help protect on-premise Windows logins. On-premise AD integration and capabilities, however, are an add-on rather than a native feature. Users must install an additional piece of software to integrate Duo with their AD environment.
  • Duo has plenty of options for adding new users — IT admins can onboard new users from services such as Microsoft Azure AD, on-premise AD, or Lightweight Directory Access Protocol (LDAP).
  • While Duo offers a straightforward MFA experience, it lacks the overall network visibility provided to admins by Duo MFA alternatives like UserLock.
  • Duo allows admins to report on the deployment status of their MFA, but it might not offer enough session control for some organizations.
  • Duo lacks some offline MFA options when compared with alternatives, like UserLock.
  • Duo’s RDP MFA option does not allow for granular configurations, such as user or group-level settings.

Thales SafeNet Authentication Service (SAS)

Thales SafeNet Authentication Service (SAS) is an on-premise authentication solution. It offers secure authentication through various MFA methods.

Overall, SAS has a broad use case coverage. It offers support for many connection types, such as VPNs, VDI, cloud applications, local network access, and web portals. It also has other potential advantages and downsides.

  • SAS can be straightforward to implement and roll out to new users, although there is a degree of manual admin integration.
  • On-premise AD users may find that SAS does not offer granular MFA policies by user, group, organizational unit, or connection type.
  • Users that also require single sign-on (SSO) must install an additional piece of software.
  • Admins that want a large degree of session control and system visibility might find that SAS lacks certain functionalities when compared to other MFA solutions like UserLock — especially when reporting on Windows logins or RDP connections.
