About OpenSnitch
OpenSnitch is an interactive application-level firewall for GNU/Linux systems inspired by macOS's Little Snitch, providing real-time visibility and control over outbound network connections made by every application. It intercepts connection attempts at the process level and presents the user with a popup dialog to allow, deny, or create persistent rules for each application's network activity. Security-conscious users, malware analysts, and privacy advocates use OpenSnitch to detect unauthorized network communication, identify data exfiltration attempts, and enforce strict application-level network policies. The tool features a Qt-based GUI with connection logging, traffic statistics, and rule management, making it invaluable for monitoring suspicious software behavior and ensuring that only authorized applications communicate over the network.
About Tirith
Tirith is a terminal security layer that protects developers and AI coding agents from terminal-based attacks. It intercepts and blocks homograph URL attacks (lookalike characters in URLs), dangerous pipe-to-shell patterns (curl | bash), ANSI escape sequence injection, obfuscated payloads, and other terminal-level threats. Ships with 80+ detection rules updated daily from threat intelligence feeds. Particularly relevant as AI coding agents become common - Tirith prevents agents from being tricked into executing malicious commands via prompt injection or supply chain attacks in terminal output.
