The short version

  • Each has a real cost: pfSense pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle; 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: pfSense covers Stateful firewall and NAT, 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.

pfSense

  • A home user or small business wanting a free, fully-featured firewall on commodity hardware with no licence costnot ZeroTier
  • A business wanting an integrated firewall appliance with vendor support, typically buying a Netgate appliance bundled with pfSense Plusnot ZeroTier
  • A team wanting to evaluate advanced features like real-time threat intelligence before committing to Netgate hardware or a Plus migrationnot ZeroTier
  • An organisation replacing an expensive commercial firewall with an open source alternative while retaining the option to add commercial support laternot ZeroTier

ZeroTier

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

Where each one falls short

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

pfSense

  • pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle
  • Running Plus on non-Netgate hardware depends on Netgate's current migration terms, which have changed over time, so a buyer planning to use white-box hardware with Plus should verify current eligibility rather than assume it works as it did previously
  • CE has no official vendor support channel; a business relying on it for production firewalling without a support contract is self-supporting on community forums
  • Some newer features and threat intelligence integrations are Plus-only, so CE users do not get feature parity going forward even though both editions remain under active development
  • Netgate's own appliance pricing and the terms of the CE-to-Plus migration path are not always clearly presented in one place, requiring some digging to understand the real total cost of a Plus deployment on non-Netgate hardware
  • As with any self-managed firewall, security depends on the operator applying updates and correctly configuring rules; there is no managed security operations layer included even in Plus

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
