Google Cloud announced some new identity tools today at Google Cloud Next designed to simplify identity Access Management within the context of the BeyondCorp Zero Trust security model.

Zero Trust, as the name implies, means you have to assume you can’t trust anyone using your network. In the days before the cloud, you could set up a firewall and with some reasonable degree of certainty assume people inside had permission to be there. The cloud changed that, and Zero Trust was born to help provide a more modern security posture that took that into account.
