How does a virtual private network (VPN) work?
A virtual private network (VPN) provides an encrypted connection for devices to a network over the Internet. An encrypted connection ensures secure transmission of confidential data. Such a connection prevents unauthorized persons from accessing traffic and provides secure remote operation for authorized users. VPN is widely used in corporate environments.
What is secure remote access?
Secure Remote Access provides a secure and reliable way for users and devices to remotely connect to the corporate network. It uses a VPN solution that applies strict user and device authentication procedures. A VPN solution allows you to validate a device against certain requirements (also known as device status) before it is allowed to connect remotely.
Is VPN traffic encrypted?
Yes, traffic in a virtual network is secure because it creates an encrypted connection over the Internet protocol called a tunnel. VPN traffic from a device such as a computer, tablet, or smartphone is encrypted as it travels through this tunnel. Employees working outside the office can use the virtual network to access the corporate network.
