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

SonicWall

  • Product line page names no price for any firewall model, series or bundled security service
  • Product tiers are segmented strictly by business size (TZ80 for micro-SMBs up to NSsp for large enterprises), so a growing business must migrate hardware series rather than scale within one model
