I’ve been in the security space for decades. The bulk of that time has been in identity and access management (IAM). I’ve even published a McGraw-Hill book on the subject. IAM is my baby. But my time in IAM has always been focusing on Day One stuff, as in, I know who you are, so now I’m going to provision you to the apps you can use as part of your role. Recently, I got an invite to do Day Zero stuff, as in, I don't provision you until I know you are truly who you say you are. Day Zero is ID verification. So I've moved my focus a little farther up the stack, touching the identities before they're fully formed. I made this career change because 1) I wanted a change of scene, and 2) Sunil Mahdu.
