Project Overview

Kolpolok Limited partnered with an Italian VPN provider to modernize their legacy application, which had been losing users due to poor usability and its failure to bypass VOIP restrictions across several European markets. The goal was to rebuild the product from the ground up—creating intuitive, high-performance VPN applications for all major platforms and delivering a robust backend system that simplified business operations.

Kolpolok developed native VPN applications for mobile and desktop with a one-tap connect UI, ensuring frictionless use for all audiences. The integration of WireGuard and OpenConnect protocols provided stable, high-speed connections optimized for VOIP use, while the redesigned admin console allowed the client’s internal team to manage everything—from user subscriptions to payment analytics—through a single, unified dashboard.
