WireGuard VPN Infrastructure

WireGuard VPN Infrastructure Challenge A distributed team of 15+ engineers working across multiple locations needed secure, low-latency access to internal corporate infrastructure — without relying on heavyweight legacy VPN appliances. The existing setup introduced significant overhead, was difficult to maintain, and caused frequent connectivity issues for remote employees. The goal was to replace it with a lightweight, self-hosted solution that is fast, auditable, and easy to scale. Solution 1.
