A Virtual Private Network (VPN) is a cybersecurity technology that creates a secure, encrypted connection over a public network, typically the internet. It functions as a protective tunnel that encrypts all internet traffic and routes it through a remote server operated by the VPN provider.

How VPNs Work

When a user connects to a VPN, the following occurs:

• Encryption: All data transmitted between the user's device and the VPN server is encrypted, making it unreadable to potential interceptors
• IP Masking: The user's real IP address is hidden and replaced with the VPN server's IP address
• Secure Tunneling: Data travels through an encrypted tunnel, protecting it from unauthorized access

Key Benefits

VPNs provide several critical security advantages:

• Privacy Protection: Prevents third parties from monitoring online activities or tracking user location
• Secure Remote Access: Enables employees to safely connect to corporate networks from any location
• Public Wi-Fi Security: Protects data when using untrusted or unencrypted wireless networks
• Data Confidentiality: Ensures sensitive information remains protected during transmission

Common Use Cases

Organizations deploy VPNs to enable secure remote work and protect business communications. Individuals use VPNs to safeguard personal data, maintain privacy from surveillance, and secure their connections on public networks. VPNs have become an essential component of modern cybersecurity frameworks for defending against data interception and maintaining digital privacy.
