The concept of a traditional security perimeter has faded in the era of cloud-native work. Firewalls and physical network boundaries no longer define the edges of your environment. We've been calling identity the "new" perimeter for over a decade: it determines who has access, from where, and under what circumstances. This makes identity protection the most critical layer in your security strategy. When identity controls are weak or misconfigured, an attacker does not need to break into your systems. They simply log in. Every action beyond that point is implicitly trusted.
