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

HAProxy

  • Configuration syntax is dense and unforgiving, with a steep initial learning curve
  • No automatic certificate management, unlike newer servers that treat it as default behaviour
  • The built-in stats page is basic, so real observability needs exporters and dashboards
  • A dedicated load balancer is more machinery than small deployments need
