What type of access does Network Access Server (NAS) facilitate?

Network Access Servers (NAS) primarily facilitate remote access through Virtual Private Networks (VPNs). This capability allows users to securely connect to a private network over the internet, enabling them to access resources, services, and data as if they were locally connected to the network. The use of VPNs ensures that the data transmitted is encrypted and secure, thereby protecting sensitive information from unauthorized access.

The focus of a NAS is on enabling secure connections for remote users, making it an essential component for organizations that support remote work, remote management, or have branch offices requiring secure access to the central network. This function greatly enhances flexibility and accessibility for users who are not physically present at the organization’s location.
