Device posture plays a crucial role in Zero Trust Network Architectures (ZTNA) as it provides critical context for any least-privileged authorization decision. The state of a device's security features, such as firewall status or OS version, is essential to determine whether to authorize access to protected resources. Traditional approaches to secure access have become less effective due to the dynamic nature of user devices and the increasing number of unmanaged endpoints. Device posture checks must be part of every access request, especially when more devices are owned by users, contractors, and third parties. Twingate's Zero Trust solution is uniquely positioned to unify device posture checks within a single, easily-managed system, providing a straightforward way to create and enforce granular least-privilege-access policies on every user device.
