Open-source VPN software: performance comparison for remote access

The use of Virtual Private Networks (VPN) as a mean to secure communication has become increasingly important with the growth in remote working. While vendor supplied VPN solutions are widely available, there is a growing trend to evaluate and implement solutions based on open-source software. In th...
