What is a VPN?

What is a VPN?

A Virtual Private Network (VPN) creates a secure, encrypted connection between devices over the internet or a private network. VPNs allow users to access internal systems remotely—while protecting data from interception, tampering, or exposure. In modern enterprise environments, VPNs are critical for enabling safe remote work and site-to-site communication.

How VPNs Work

• Encryption: All traffic is encrypted end-to-end using protocols like IPsec, OpenVPN, or WireGuard.
• Tunneling: VPNs create a virtual “tunnel” between devices that isolates traffic from the public internet.
• Authentication: Secure credentials, certificates, or multi-factor authentication verify user identity.

Types of VPNs

• Client-to-Site VPN: Allows individual users (remote employees, contractors) to securely connect to the company network.
• Site-to-Site VPN: Connects entire networks across different locations, such as branch offices or data centers.
