+# Greywall
+
+> Container-free, default-deny sandboxing with real-time observability for AI agents on Linux and macOS.
+
+Greywall is an open-source CLI tool that wraps any AI agent (Claude Code, Codex, Cursor, Aider, and others) in a kernel-enforced sandbox. It uses five security layers on Linux (Bubblewrap namespaces, Landlock filesystem, Seccomp BPF syscall filtering, eBPF monitoring, and TUN+SOCKS5 network proxy) and four on macOS (Seatbelt sandbox, filesystem policy, log stream monitor, and proxy-based network control). Default-deny policy means nothing is accessible unless explicitly granted. Built by Greyhaven, licensed Apache 2.0.
+
+## Key Features
+- Filesystem isolation (kernel-enforced read/write/deny per path)
+- Network isolation (all traffic routed through GreyProxy)
+- Command blocking (detects blocked commands in pipes, chains, nested shells)
+- Real-time violation monitoring (every denial captured with full context)
+- Learning mode (auto-generates least-privilege templates from observed access)
+- Syscall filtering (blocks 27+ dangerous system calls via Seccomp BPF)
+- Dynamic allow/deny controls (adjust policies live without restarting)
