Access Assurance solves many complexity challenges associated with traditional NAC offerings, by removing on-premises server hardware, providing inherent service high-availability, resilience, as well as automatic at-run-time feature updates, security, and vulnerability fixes. Juniper Mist Access Assurance extends Juniper Mist IoT Assurance capabilities, which simplifies on-boarding for headless IoT and BYOD devices, Access Assurance extends support to onboard wired and wireless devices with 802.1X authentication or MAC Authentication Bypass (MAB) methods for non-802.1X devices.

Access Assurance uses hundreds of different vectors to match the identity of the user and the device, such as X.509 certificate attributes, user group memberships, device compliance metrics, as well as location context. These vectors help determine identity-based network admission criteria, such as the network segment or a microsegment a device should connect to and the network policy that should be dynamically applied to a user.
