What is a Virtual Private Network (VPN)?

A VPN creates an encrypted connection from a single device to a larger virtual private network, typically powered by one or more web servers. Traffic and internet browsing passed through the VPN encrypts data so that it cannot be intercepted by a government or ISP, or anyone else monitoring. This creates a more secure browsing environment while also preventing any websites from seeing browsing history from your actual IP address.

Why Are Virtual Private Networks (VPNs) Used?

VPN networks are very popular among corporations and are usually the preferred way for employees to login to a corporate network, due to security concerns. VPNs are growing in popularity with individuals and personal browsing as well. Censorship and crackdowns in authoritarian countries have made it difficult for users to reach many popular websites, including Google. Tunneling your traffic through a VPN IP address would allow an individual to bypass any restrictions from their government or ISP.

Are VPN Connections Considered Bad?

Yes and no — VPN IP addresses can be used for both good and bad actions. Examples of good actions would be accessing a corporate office network, anonymous web browsing, and protecting privacy online. However, since VPNs do hide your real IP address and location, cybercriminals and bad actors like to use these connections to engage in fraudulent activity such as credit card chargebacks, creating fake accounts, generating click fraud, and similar behavior. Users abuse VPNs and proxy connections more often than using this technology for good faith actions.
