Identity as the primary attack surface: What modern breaches are really exploiting

Modern breaches are exploiting identity as the primary attack surface, rather than traditional network perimeters. Decades of focus on protecting network perimeters through firewalls, intrusion detection systems, and endpoint security have become less effective as users, infrastructure, and applications have expanded beyond confined networks. This shift has rendered traditional security strategies obsolete, with attackers now targeting identity vulnerabilities to gain access to sensitive information. The notion of a secure network perimeter has become an outdated concept, as businesses have invested heavily in security controls that no longer address the primary attack vector¹. As a result, security practitioners must adapt to this new reality, prioritizing identity-centric security measures to stay ahead of emerging threats. This change in attack surface matters to security professionals because it necessitates a fundamental transformation in their approach to security, one that prioritizes identity protection above traditional perimeter defense.
