How can I protect my VPN with two-factor authentication?

Question

In our company we’re under new compliance requirements and the auditors are pressing us to implement multi-factor authentication for any VPN access. Since we’re using Barracuda SSL VPN, I need to research how we can enforce MFA without creating a heavy burden for the team. Is there a resource that explains the end-to-end process for Barracuda and covers both the RADIUS integration and token deployment?

I'm glad it was helpful because I had a hard time finding this information myself; there isn't much of it out there.

That’s perfect. Understanding the threat model (password + token) and how the setup strengthens our defenses helps me justify the project to our managers. I’ll follow the guide and draft a deployment plan with user-groups, token distribution, and fallback procedures. Hopefully we’ll get this feature live before the next audit.

Yes, absolutely. There’s a comprehensive article at barracuda vpn that goes into how to set up Protectimus as the RADIUS server for Barracuda SSL VPN, configure the authentication policies, and enroll users with tokens or mobile apps. It also highlights security benefits — for example, how using time-based OTPs makes credential theft or brute force far less feasible because the attacker would need the token and only has around thirty seconds to use it.
