A firewall inside your Python app, in one line
List the servers your app may talk to, in one line of Python. Any other connection Python makes is refused before it opens, whether it comes from your own code, a dependency or code an AI wrote. Free and open source, with no proxy to run.
Tethered 1.0 is an open-source security tool for Python applications that restricts network connections to a predefined list of servers. It prevents unauthorized connections from the application, its dependencies, or AI-generated code.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
