If you have ever used a VPN service, chances are it was based on OpenVPN, an open-source protocol that we first developed 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.
