Zero Trust Network Access (ZTNA) is a security model that requires verification and authentication of every user and device attempting to access a network. This approach is founded on the principle of “never trust, always verify,” meaning no user or device is trusted by default, regardless of their location relative to the corporate network. ZTNA secures access to applications and resources based on identity, device posture, and other contextual factors, rather than relying solely on traditional network perimeters.
ZTNA addresses the limitations of traditional VPNs and perimeter-based security models, which have become less effective in modern, dynamic, and distributed IT environments. The rise of remote work and cloud adoption has made the traditional security perimeter increasingly porous, challenging organizations to enforce consistent security policies and protect sensitive data. ZTNA offers a more granular and adaptive approach to access control, allowing organizations to secure access to applications and resources based on the principle of least privilege.
Implementing ZTNA can help organizations reduce their attack surface, mitigate the risk of unauthorized access, and improve their overall security posture.
