Where each one falls short

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

Bitdefender Total Security

  • VPN limited to 200MB per day, insufficient for streaming video or extended browsing sessions
  • Limited features on Apple devices with iOS version lacking scheduled scans, firewall, file shredder, and other tools
  • Failed to detect 10% of virus samples during in-house testing, falling short of perfect detection rates
  • Auto-renewal billing issues with complaints about unauthorized recurring charges and difficulties with refunds
  • Device optimization tools less extensive than competitors, lacking game booster, driver updater, startup manager, and battery usage manager

Caddy

  • Smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments
