Safing was originally founded by a small team of privacy activists in Austria. Portmaster and SPN are now developed and operated by IVPN.
Every network connection your device makes can expose information to your ISP, advertisers, or anyone observing traffic. Portmaster monitors and filters those connections at the application level.
Open-source code can be reviewed, audited, and contributed to by anyone. That's how trust is built in software.
Trust in software that handles your data has to be earned. That means clear ownership, honest business practices, and no hidden influences.
Our goal is to give users meaningful control over their own network traffic, across all applications.
Portmaster's core privacy features are free. Paid plans add investigative tools and SPN access. Revenue supports ongoing development.
