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; ProtonVPN free plan limited to one device at a time
  • They diverge on capability: pfSense covers Stateful firewall and NAT, ProtonVPN covers No-logs policy.
  • Prices and features above were last checked on 1 September 2026.

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

ProtonVPN

Answered from the vendors’ own pages

pfSense: What is the difference between pfSense CE and pfSense Plus?

pfSense: Can I run pfSense Plus on my own hardware?

It is possible through a migration from a CE installation via Netgate's official channel, but the terms and availability of that path have changed over time and should be confirmed directly with Netgate.

pfSense: Is pfSense CE really free with no catch?

Yes, CE has no licence fee and no hardware lock-in, though it comes with community rather than vendor support.
