Two-Factor Authentication (2FA/MFA) for Sophos UTM

Sophos UTM offers advanced next-gen cloud sandboxing technology that provides a whole new level of ransomware and targeted attack protection, visibility, and analysis. Miniorange works with Sophos UTM VPN to provide an additional layer of authentication and protection for administrators and end-users that access Sophos VPN and firewall.

After setting up your own Sophos UTM SSL VPN, you may want to enhance its security. One way to do that is to enable Multi-Factor Authentication (MFA) for Sophos VPN. To boost security, activate Two-Factor Authentication (2FA) for your Sophos VPN Managed AD directory. When you enable 2FA, your users must provide their username and password (first factor) as usual, as well as an authentication code based on your configured 2FA method to gain access to Sophos UTM SSL VPN.

As a second factor, miniOrange offers 15+ MFA methods to choose from, such as Google/Microsoft/Authy Authenticator, Push Notifications via the in-house miniOrange Authenticator app, OTP via SMS/Email, and many more.

Types of 2FA Authentication with RADIUS

Depending on the VPN client, 2-factor authentication can take two forms..

VPN Clients that support RADIUS Challenge.
VPN Clients that do not support RADIUS Challenge.

miniOrange 2FA authentication for Sophos UTM Login

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.

Primary authentication initiates with the user submitting his Username and Password for Sophos UTM.
User request acts as an authentication request to RADIUS Server(miniOrange).
miniOrange RADIUS server passes user credentials to validate against the credentials stored in AD (Active Directory) / Database.
Once the user's first level of authentication gets validated AD sends the confirmation to RADIUS Server.
Now miniOrange RADIUS Server asks for a 2-factor authentication challenge to the user.
Here user submits the response/code which he receives on his hardware/phone.
User response is checked at miniOrange's RADIUS Server side.
On successful 2nd factor authentication the user is granted access to login.
