Build a Secure VPN (Virtual Private Network)

Public networks and ISPs often track and log user activity. A custom VPN ensures your data is encrypted end-to-end, IP addresses are masked, and no third-party logging occurs. It also gives you complete control over routing and encryption protocols, improving both privacy and performance.

The VPN routes traffic through a secure tunnel using strong encryption like AES-256 and protocols such as OpenVPN or WireGuard. It provides client authentication, traffic routing, kill-switch support, and DNS leak protection to maintain user anonymity and security.

When a user connects to the VPN, a secure tunnel is created between their device and the VPN server. All internet traffic is routed through this encrypted channel, masking the user's original IP and preventing packet sniffing or tracking by ISPs, hackers, or third parties.

• Client initiates a VPN handshake using a secure protocol (e.g., OpenVPN or WireGuard).
• User is authenticated via credentials or certificates.
• A tunnel is created, encrypting all outgoing and incoming traffic.
• Traffic is routed through the VPN server’s IP, masking the user’s identity.
• DNS queries and routing policies are handled server-side to prevent leaks or bypassing.
