Architecture-level security for organizations: identity, segmentation, and the models that replaced the perimeter.
Home › Enterprise Security
Enterprise security failures are usually architectural rather than technical. Flat internal networks, standing administrative privilege, and implicit trust granted by network location turn a single compromised endpoint into organization-wide access. This category covers the models built to remove that implicit trust — most directly Zero Trust Architecture, following the NIST SP 800-207 definition rather than vendor marketing.
The focus is on what implementation actually involves: identity as the control plane, per-request authorization, microsegmentation, device posture, and continuous verification — along with honest treatment of migration cost, the legacy systems that resist it, and the organizational friction that stalls these programs more often than any technical limitation does.
