The short version

  • Each has a real cost: Avast One ransomware and Wi-Fi vulnerability protection only on paid plans; ZeroTier the free tier caps at 10 devices and 1 network, which a small business will outgrow quickly and then face both a base plan fee and per-device overage charges
  • They diverge on capability: Avast One covers Antivirus, ZeroTier covers Peer-to-peer mesh networking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Avast One

  • Antivirusnot ZeroTier
  • Internet Securitynot ZeroTier
  • Privacy Toolsnot ZeroTier

ZeroTier

  • A hobbyist or small home lab wanting free virtual LAN connectivity across devices without a business tiernot Avast One
  • A small business connecting a handful of remote offices or remote workers into one virtual network on the Essential plannot Avast One
  • A growing company scaling past the free device limit that needs multiple networks and predictable per-device overage pricingnot Avast One
  • A service provider or large IoT deployer needing custom Enterprise or Quantum packaging for very large device countsnot Avast One

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

ZeroTier

  • The free tier caps at 10 devices and 1 network, which a small business will outgrow quickly and then face both a base plan fee and per-device overage charges
  • Per-additional-device pricing on Essential ($2.00 each) is proportionally expensive for a team that grows just past the included count, since the jump from free to paid is immediate once the 11th device joins
  • Relay fallback, when a direct peer-to-peer path cannot be established (common behind certain NAT or firewall configurations), routes traffic through ZeroTier's infrastructure, adding latency and a dependency the buyer does not fully control
  • Enterprise and Quantum tiers are entirely custom-quoted, so very large deployments cannot be budgeted from the public pricing page
  • Network administration for larger deployments (Scale and above) still requires understanding ZeroTier's access control and network rule model, which has a real learning curve beyond simple device joining
  • As with any software-defined mesh network, security depends on correctly configured network authorization; a misconfigured network can expose devices more broadly than intended
