Sophos UTM offers advanced next-gen cloud sandboxing technology that provides a whole new level of ransomware and targeted attack protection, visibility, and analysis. After setting up your own Sophos UTM SSL VPN, you may want to enhance it's security. One way to do that is to enable Multi-Factor Authentication (MFA/2FA) for Sophos VPN. Configuring Sophos UTM MFA/2FA solution, let your users to enter their username and password (first factor) as usual, and as a second factor they have to enter an authentication code which will be shared virtually on their device or in the form of a hardware token. This 2FA/MFA setup for Sophos UTM adds an additional security measure to prevent unwanted user access to your Sophos UTM SSL VPN.
The 2-factor authentication can be of two types depending on the VPN clients.
miniOrange accomplishes this by acting as a RADIUS server that accepts the username/password of the user entered as a RADIUS request and validates the user against the user store as Active Directory (AD). After the first level of authentication, miniOrange prompts the user with 2-factor authentication and either grants/revokes access based on the input by the user.
miniOrange supports multiple 2FA/MFA authentication methods for Sophos UTM secure access such as, Push Notification, Soft Token, Microssoft / Google Authenticator etc.
|miniOrange Authenticator||Soft Token|
|miniOrange Push Notification|
|Mobile Token||Google Authenticator|
|SMS||OTP Over SMS|
|SMS with Link|
|OTP Over Email|
|Email with Link|
|Call Verification||OTP Over Call|
|Hardware Token||Yubikey Hardware Token|
|Display Hardware Token|
You can opt for any of the 2FA methods to secure your Sophos UTM. To integrate 2FA, you can enable RADIUS authentication in Sophos UTM and configure policies in miniOrange to enable or disable 2FA for users.

Refer our guide to setup LDAPS on windows server.
Note: Below steps are used to enable one time or manual sync. To enable sync on scheduled basis, you should use LDAP gateway module. Read more and download the LDAP gateway module.
1. Create User in miniOrange
2. Bulk Upload Users in miniOrange via Uploading CSV File.
(The Active Directory Group Provisioning (Sync) setup is done. Now, whenever a user is created or modified in LDAP server and if the Assign Users to groups is enabled, then user group attribute from the LDAP server will be automatically synced and the user group will be assigned or changed accordingly in miniOrange.)
