Why Identity Is the New Perimeter, and How IAM Still Lets Organisations Down

For years, security teams were taught to think in terms of edges, boundaries, and the network perimeter. That made sense when most users, systems, and data sat inside infrastructure the organisation owned and controlled. It makes far less sense now. Staff work remotely, applications live across cloud platforms, suppliers plug directly into shared systems, and automation now acts with privileges that used to belong only to people. In that world, identity has become the control point that matters most. If an attacker can authenticate successfully, or abuse an account that already has access, many traditional security layers become much less relevant. That helps explain why so many serious incidents now begin with a stolen credential, a weak service account, an over-privileged administrator, or a trust relationship nobody has reviewed in far too long.
