Anecdata

Christopher Glyer

I was talking to a CISO the other day and he mentioned that when his org implemented MFA with the MSFT authenticator app it reduced their aggregate number of security incidents by ~25%. The rollout of Yubikeys for all employees reduced # of security incidents another 25%.
