6WIND Virtual Service Router (VSR) vs DefGuard Server: Side-by-Side Comparison (2026)

DefGuard Server

SMB and mid-market teams needing a self-hosted VPN with actual device trust will find DefGuard Server's zero-touch enrollment via Active Directory and pre-logon VPN mode genuinely useful; it solves the "how do we authenticate before the user even logs in" problem that most commercial VPN vendors ignore. Native Windows and macOS clients plus WireGuard's performance backbone mean you're not fighting bloated legacy protocols. Skip this if you need vendor-managed cloud infrastructure or expect hands-off support from a large vendor; DefGuard's seven-person team means you're buying into self-sufficiency.
