Protect SSH Sessions & UNIX Logins

Duo for UNIX

By securing your local SSH and remote UNIX logins with Duo’s Trusted Access solution, you can keep production, test and development environments secure against remote attacks on your production systems and other critical networks.

We verify the identities of your users with two-factor authentication and check the security health of their devices before granting them access to your production environment.

Duo’s UNIX integration is open source and can be easily installed on all major UNIX distributions, including Linux (Red Hat Enterprise Linux, CentOS, Debian and Ubuntu), BSD (FreeBSD, NetBSD, OpenBSD), Solaris and AIX.
