Utilize AD/LDAP/POP3/RADIUS servers for BYOD (Bring Your Own Device) identity verification, quickly identify devices and manage connection permissions, and establish zero trust security between personnel and devices. After a person enters the corporate or government network, the system will redirect the webpage for authentication. After verifying their identity according to the enterprise security policy, the system will automatically grant the person corresponding access permissions (external/internal/specific network segments) and effective time. It can also require the device to undergo regular verification every fixed time.
