VPN
A Virtual Private Network (VPN) is a technology that creates a secure, encrypted connection over a less secure network, such as the internet, allowing users to send and receive data as if their devices were directly connected to a private network. It masks the user's IP address and encrypts internet traffic to enhance privacy and security, commonly used to access restricted resources or protect sensitive information from eavesdropping.
Developers should learn and use VPNs when working remotely to securely access company networks, databases, or internal tools, ensuring data protection against cyber threats. It is essential for scenarios like testing geo-restricted applications, conducting secure code deployments, or collaborating on sensitive projects over public Wi-Fi, as it prevents unauthorized access and maintains confidentiality.
