A VPN client is end-user software that creates an encrypted tunnel from a device to a company firewall or router, allowing secure access to internal resources over the internet. section 16.3.2
A remote-access VPN client:
- Creates a separate encrypted tunnel for each connected device rather than sharing one tunnel among multiple hosts. section 16.3.2
- Typically uses Transport Layer Security (TLS), although IPsec is also an option. section 16.3.2
- Provides a secure pathway to resources such as internal file servers during remote work. section 16.3.2
- Differs from a site-to-site VPN, which connects networks through routers instead of connecting each individual end-user device. section 16.3.2
