A virtual private network (VPN) is an Internet security tool that establishes a secure link between client computers and one or more servers.
Users can safely connect to the internal network of a business or to the Internet in general using VPNs.
Businesses often use a VPN to build a single shared network between numerous office sites or to provide distant employees access to company apps and data.
The end objective in both situations is to keep web traffic from being exposed on the public Internet, especially information that contains private data.
Why are VPNs necessary to accomplish this?
Consider remote workers as an example.
When employees work on-premises, they can connect their computer and mobile device directly to the business’s internal network.
However, if an employee works remotely, their connection to that internal network must take place over the public Internet, potentially exposing their traffic to on-path attacks and other methods of snooping on sensitive data.
Encrypting that traffic with a business VPN or another security service keeps it safer from prying eyes.
