This white paper provides a step-by-step framework for adopting Zero Trust Network Access in modern enterprise environments. It explains why perimeter-based security fails in hybrid and remote work models and outlines how ZTNA enforces continuous verification of users, devices, and applications. The guide covers strategy definition, ZTNA models, asset and user discovery, identity integration, device posture checks, micro-segmentation, granular policy enforcement, and least-privilege access. It also addresses monitoring, logging, user training, and continuous improvement. Practical guidance helps organizations reduce attack surfaces, prevent lateral movement, and securely enable digital transformation with scalable Zero Trust principles.
