Abstract: In the early stages of internet adoption, secure data transmission was largely confined to closed networks or hardwareintensive private infrastructures. As digital communication expanded globally, the need for accessible and reliable encryption over public channels became paramount. Traditional security mechanisms, though foundational, often lacked the flexibility, scalability, or resilience demanded by today’s distributed and mobile user base. This study presents a Virtual Private Network using OpenVPN. The system leverages a Linux-based server. . It sustained encrypted communication with minimal packet loss, reduced latency overhead to under 15%, and successfully mitigated spoofing, sniffing, and man-in-the-middle attack scenarios. Validation was conducted using tools such as Wireshark and nmap to ensure compliance with standard security practices. By combining proven cryptographic techniques with an open-source and configurable framework, this implementation demonstrates a scalable, secure, and adaptable VPN solution for institutions prioritizing secure remote access.
