Array AG Series SSL VPN Remote Access vs DefGuard Server: Side-by-Side Comparison (2026)

Mid-market and enterprise teams deploying hybrid infrastructure need the Array AG Series SSL VPN Remote Access for its device-identity validation and multi-layer access control, which stops compromised endpoints from reaching sensitive applications even after authentication succeeds. The platform supports up to 256 customizable virtual portals with resource-specific policies and runs on hardware or virtual appliances, giving you granular segmentation without redesigning your network. Skip this if your primary concern is detecting lateral movement post-breach; Array locks down the access gate effectively but doesn't monitor what happens after users connect. 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.
