net‑sentinel

A deny‑by‑default outbound monitor. Every connection your machine makes is matched against a learned allowlist — plaintext is flagged, first‑seen anomalies are caught, and nothing is trusted by default.

Posture

The safe, aggregate view from the live engine — no addresses, no processes. This is all it ever exposes.

A scan, walked through

Illustrative connections (documentation IPs). Watch the policy decide: allow what's known, deny plaintext & unlisted, alert on the genuinely new.

How it works. net‑sentinel is a stdlib‑only engine that watches outbound sockets, matches each against a learned allowlist, and tiers anything unmatched (INFO / WARN / CRITICAL). It's deny‑by‑default: an endpoint earns trust, it isn't granted it. Output is an atomic JSON with a generated_at freshness contract — no cloud, no secrets, nothing leaves the host.

This page is an illustrative demo: synthetic data over documentation IP ranges. A live version would surface only the aggregate posture above — never a real connection.  ← back
