A virtual private network (VPN) is a connection established over a secure connection with an existing network, usually the public Internet, and is secured through authentication and encryption.
A virtual private network (VPN) is a method of providing secure remote access. A virtual private network can help prevent unauthorized access to a company’s network and sensitive data. A VPN hides your IP address and makes your connection to the Internet more secure.
VPNs have become a crucial part of many organizations’ security strategies regardless of business size, industry vertical, or geographic location. VPNs provide a way for authorized remote users to gain access to files, databases, and other network applications in a secure manner.
Due to the inherent security risks of the Internet, companies providing remote access and telecommuting choices must protect their private data through a VPN.
An even more secure version of the VPN is the Secure Sockets Layer Virtual Private Network (SSL VPN). An SSL VPN uses the Secure Sockets Layer (SSL) protocol to create a secure and encrypted connection over the Internet. The SSL VPN was created to ensure enhanced security and privacy.
There are many techniques and components for establishing and using a VPN.
