tethered features
- Process-wide activation. Call activate() once to set a global allow-list for all outbound sockets.
- Scoped tightening. Use scope() to apply tighter restrictions to specific code paths or libraries.
- Zero external dependencies. Implements checks by hooking Python's native socket layer, no extra packages needed.
- Works with common frameworks. Compatible with requests, httpx, aiohttp, Django, Flask, FastAPI, and any socket-based library.
- Subprocess propagation. Automatically propagates policies to child processes via site-packages bootstrap.
- Locked-mode integrity checks. Detects tampering of policy payloads and filesystem changes.
- DNS divergence repair. Falls back to safe DNS resolution when standard lookup fails.
- Simple API. One-line allow-list declaration blocks unauthorized network calls with EgressBlocked exceptions.
