What is a VPN?
A VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection between a device and a network via the internet. It is used to protect data, hide IP addresses, and provide remote access to internal systems.
How does a VPN work?
A VPN routes traffic through an encrypted tunnel between the user’s device and a VPN server. Protocols such as IPSec, OpenVPN, and WireGuard are commonly used to secure the transfer.
Benefits of a VPN:
- Increased security: Protects against intrusions and data theft.
- Remote access: Allows secure connection to company networks.
- Protection on public networks: Ensures encryption even on open WiFi.
Different types of VPN:
- Remote Access VPN: Provides secure access for users to internal resources.
- Site-to-Site VPN: Connects multiple offices or networks.
- Mobile VPN: Optimized for mobile devices and unstable connections.
