Cisco deploys Duo for workforce zero trust

Security is constantly changing. As we move forward, Duo is going to be a critical enabler to allow us to have zero trust. Where you are, what you want access to, from what devices, and being able to make that very dynamic. And that's what I'm looking forward to enabling through Duo and the Cisco Zero Trust platform.
