Portmaster SPN official product pages
Pricing snapshot, SPN architecture snapshot, and ownership snapshot.
Portmaster is a local network monitor, application firewall, privacy filter, and secure resolver for Windows and Linux. The paid SPN redirects selected connections through separately calculated onion-encrypted routes. It can use a different exit address for each connection and exposes per-application routing controls.
The current pages list Portmaster Pro at 8 euro per month or 80 euro per year for up to five devices. They also state that Portmaster and SPN are now developed and operated by IVPN. The pages describe an account-based subscription, not an unlinkable credential design.
