About us:

If you have ever used a VPN service, chances are it was based on OpenVPN, an open-source protocol that we first developed over 16 years ago and that has since become the de-facto industry standard implemented in the majority of commercial VPN software. Millions of companies and individual users worldwide have trusted us to transmit their sensitive data in a secure, encrypted fashion. But this was just the beginning...
We are now developing a whole new range of products aimed to deliver our services in a scalable fashion to tens and even hundreds of millions of customers worldwide. To support this ambitious goal, we have set up an R&D center in Ukraine that will, jointly with our headquarters in the Silicon Valley, be the cornerstone of the future generation of VPN technologies used across the globe. This is the story that we are inviting you to join!
