Zero Trust Network Access (ZTNA) is a cybersecurity approach that challenges the traditional security model of trusting everything within a network perimeter. Instead, ZTNA operates on the principle of “never trust, always verify,” requiring authentication and authorization for every access request, regardless of the user’s or device’s location. ZTNA employs micro-segmentation, granting access to network resources on a per-session basis.
This access is determined by multiple factors, including user identity, device health, location, and the sensitivity of the requested resource. By implementing this granular approach, ZTNA reduces the attack surface and mitigates the risk of unauthorized access and lateral movement within the network. The adoption of ZTNA enables organizations to enhance their security posture while supporting modern work practices such as remote work and bring your own device (BYOD) policies.
This security model ensures that only authorized users and devices can access specific resources, irrespective of their network environment or physical location. As cyber threats continue to evolve and remote work becomes increasingly prevalent, ZTNA offers a more robust and adaptable security framework compared to traditional perimeter-based models. This approach allows organizations to maintain strict security controls while providing the flexibility required in today’s dynamic work environments.
