What is a VPN, and how does it improve security?

A Virtual Private Network, commonly known as a VPN, is a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. This connection allows users to send and receive data as if they were directly connected to a private network, enhancing their overall privacy and security.

The primary way a VPN improves security is by encrypting the user's internet traffic, which protects sensitive information from interceptors, such as hackers or unauthorized entities. It operates by routing the user’s connection through a secure server before reaching the final destination on the internet, effectively masking the user's IP address and location. This means that any data transferred is much more difficult for others to access or tamper with.

Additionally, using a VPN can help safeguard against malicious threats when connected to public Wi-Fi networks, as it minimizes the risk of data breaches and unauthorized access to personal data. By facilitating a private and secure connection, VPNs are fundamental tools for enhancing online security and privacy.
