Mobile business has become a trend. Employees no longer stay in offices and use fixed IP addresses to access
enterprise networks, which means that users are no longer tied to IP addresses and network borders become
increasingly blurred. An employee should have the same permissions and be subject to the same security policies,
regardless of whether they are using a PC or smartphone. In this new environment, IP address-based access control and
security protection no longer meet enterprise requirements. The NGFW must define security policies based on users.
