Where each one falls short

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

Avast One

  • Ransomware and Wi-Fi vulnerability protection only on paid plans
  • Free plan VPN is limited, no data breakthrough monitoring
  • Rebuilt app in May 2026 may have stability issues

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)
