Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Defender

  • Defender Suite requires existing Microsoft 365 E3 or equivalent base licensing
  • Some Defender products use pay-as-you-go pricing with variable costs
  • Prices vary based on Microsoft agreements, requiring sales contact for custom quotes

WireGuard

  • Manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
  • No built-in support for address allocation or DHCP; all IP assignments must be manually configured
  • Limited to UDP; TCP encapsulation requires wrapper tools, making it unsuitable for environments blocking UDP
  • Stateless protocol design means lost packets trigger peer disconnection rather than transparent reconnection
  • Requires operational expertise to securely configure and deploy; not suitable for non-technical users without wrapper tools (Tailscale, Mullvad)
