Tool Review: Tailsnitch, (Tue, Jan 6th)

This piece reviews Tailsnitch, an open-source auditor for Tailscale VPN configurations, demonstrating how to run it and interpret its output. In a test run, it flagged outdated Tailscale versions (medium), non-expiring device keys and missing ACL tests (low), and various informational improvements, surfacing hardening options and some advanced features available only on paid plans. The focus is on configuration hygiene and security posture improvement rather than a specific incident or threat activity.
